Intermediation Networks and Derivative Market Liquidity: Evidence from CDS Markets

In over-the-counter markets, dealers facilitate trade by providing liquidity and acting as intermediaries. The authors present a model that links the relationships of these intermediaries to market liquidity, and they empirically test the model using supervisory data from the U.S. single-name credit default swap market (Working Paper no. 24-01).

Crash Narratives

The financial press is a conduit for popular narratives that reflect collective memory about historical events. Some collective memories relate to major stock market crashes, and investors may rely on associated narratives, or crash narratives, to inform their current beliefs and choices. Using recent advances in computational linguistics, we develop a higher-order measure of narrativity based on newspaper articles that appear following major crashes. We provide evidence that crash narratives propagate broadly once they appear in news articles and significantly explain predictive variation in market volatility. We exploit investor heterogeneity using survey data to distinguish the effects of narrativity and fundamental conditions and find consistent evidence. Finally, we develop a measure of pure narrativity to examine when the financial press is more likely to employ narratives (Working Paper no. 23-10).

Trend Inflation Under Bounded Rationality

This paper evaluates the implications of introducing bounded rationality into a New Keynesian model with trend inflation. We develop a New Keynesian model with trend inflation that departs from rational expectations and introduces cognitive discounting. In a model with rational expec­tations, higher trend inflation generates macroeconomic instability by making the economy more susceptible to equilibrium indeterminacy. We find that cognitive discounting increases the region of determinacy, and therefore, trend inflation becomes less destabilizing (Working Paper no. 23-09).

Are Short-selling Restrictions Effective?

Despite strong predictions based on theories of disagreement, limited empirical evidence has linked short-selling restrictions to higher prices. We test this relationship using quasi-experimental methods based on Rule 201, a threshold-based policy that restricts aggressive short selling when intraday returns cross −10%. When comparing stocks on either side of the threshold in the same hour of trading, we find that the restriction leads to short-sale volumes that are 8% lower and daily returns that are 35 bps higher. These price effects do not reverse after the restriction is lifted (Working Paper no. 23-08).

The Transition to Alternative Reference Rates in the OFR Financial Stress Index

The OFR Financial Stress Index (OFR FSI or FSI) is a daily market-based snapshot of stress in global financial markets. Originally, the OFR FSI was constructed from 33 financial market variables that are correlated with some form of financial stress. Seven of these variables are based on LIBOR or other ceasing and/or already-ceased benchmark interest rates. As such, these seven variables are now obsolete. However, since its inception, the OFR FSI was intended to allow for the periodic replacement of obsolete variables as the need arises (Working Paper no. 23-07).

Technology Shocks and Predictable Minsky Cycles

This paper offers an economical and internally consistent model to rationalize macrofinancial boom-bust cycles. The authors present a simple model that can clarify the interaction of optimism with capital reallocation and demonstrate how this interaction can generate predictable boom-bust financial cycles. This clarification enhances our understanding of the channels through which credit markets could threaten financial stability (Working Paper no. 23-06).

Sustainability with Risky Growth

This research will help policymakers understand how economic growth, risk, and the financial sector influence sustainability objectives. It provides a useful theoretical framework useful to help assess what policies related to growth and financial depth are likely to affect sustainability (Working Paper no. 23-05).

Anatomy of the Repo Rate Spikes in September 2019

Repurchase agreement (repo) markets represent one of the largest sources of funding and risk transformation in the U.S. financial system. Despite the large volume, repo rates can be quite volatile, and in the extreme, they have exhibited intraday spikes that are 5-10 times the rate on a typical day. This paper uses a unique combination of intraday timing data from the repo market to examine the potential causes of the dramatic spike in repo rates in mid-September 2019 (Working Paper no. 23-04).

Can Supply Shocks be Inflationary with a Flat Phillips Curve?

Empirical estimates find that the relationship between inflation and the output gap is close to nonexistent—a so-called flat Phillips curve. We show that standard pricing frictions cannot simultaneously produce a flat Phillips curve and meaningful inflation from plausible supply shocks. This is because imposing a flat Phillips curve immediately implies that the price level is also rigid with respect to supply shocks. In quantitative versions of the New Keynesian model, price markup shocks need to be several orders of magnitude bigger than other shocks in order to fit the data, leading to unreasonable assessments of the magnitude of the increase in costs during inflationary episodes. Hence, we propose a strategic microfoundation of price stickiness in which prices are sticky with respect to demand shocks but flexible with respect to supply shocks (Working Paper no. 23-03).

Fragility of Safe Assets

The market for U.S. Treasury securities experienced extreme stress in March 2020, when prices dropped precipitously (yields spiked) over a period of about two weeks. This was highly unusual, as Treasury prices typically increase during times of stress. Using a theoretical model, we show that markets for safe assets can be fragile due to strategic interactions among investors who hold Treasury securities for their liquidity characteristics. Worried about having to sell at potentially worse prices in the future, such investors may sell preemptively, leading to self-fulfilling “market runs” that are similar to traditional bank runs in some respects. Our results motivate potential policy interventions to stabilize the market during times of stress and disruption (Working Paper no. 23-02).

Digital Currency and Banking-Sector Stability

Digital currencies provide a potential form of liquidity competing with bank deposits. We introduce digital currency into a macro model with a financial sector in which financial frictions generate endogenous systemic risk and instability. In the model, digital currency is fully integrated into the financial system and depresses bank deposit spreads, particularly during crises, which limits banks’ ability to recapitalize following losses. The probability of the banking sector being in crisis states can grow significantly with the introduction of digital currency. While banking-sector stability suffers, household welfare can improve significantly. Financial frictions may limit the potential benefits of digital currencies (Working Paper no. 23-01).

Counterparty Choice, Bank Interconnectedness, and Bank Risk-taking

We investigate whether banks’ counterparty choices in OTC derivative markets contribute to network fragility. We use novel confidential regulatory data and show that banks are more likely to choose densely connected non-bank counterparties and do not hedge such exposures. Banks are also more likely to connect with riskier counterparties for their most material exposures, suggesting the existence of moral hazard behavior in network formation. Finally, we show that these exposures are correlated with systemic risk measures despite greater regulatory oversight after the crisis. (Working Paper no. 22-06).

Hedge Funds and Treasury Market Price Impact: Evidence from Direct Exposures

The increasing importance of non-bank financial intermediaries has raised new questions about the risks that hedge funds pose to the financial system. The OFR examined how changes in hedge fund exposures affect U.S. Treasury prices and the yield curve. Using confidential hedge fund data from the SEC's Form Private Fund (PF), OFR analysts calculated hedge funds' aggregate, net Treasury exposures, and their fluctuations over time. This revealed economically significant and consistent evidence that changes in hedge fund exposures are related to Treasury yield changes. Furthermore, particular strategy groups and lower-levered hedge funds were seen to have a larger estimated price impact on Treasuries. Finally, asset pricing tests show that U.S. Treasury investors demand additional return compensation due to the risks associated with hedge fund demand (Working Paper no. 22-05).

Central Bank Digital Currency: Stability and Information

One often cited concern about central bank digital currency (CBDC) is that it could make runs on banks and other financial intermediaries more common. This working paper identifies two ways a CBDC may enhance rather than weaken financial stability. First, banks do less maturity transformation when depositors have access to CBDC, reducing their exposure to depositor runs. Second, monitoring the flow of funds into CBDC allows policymakers to react more quickly to periods of stress, which lessens the incentive for depositors and other short-term creditors to withdraw assets (Working Paper no. 22-04).

Cash-Hedged Stock Returns

This paper studies firms’ cash holdings and the implications for asset prices and financial stability. Corporate cash piles vary across companies and over time, and cash holdings are important for financial stability because of their value in crises. Firms’ cash holdings earn low returns that are correlated across firms. Thus, the asset pricing results are important both for investors who are managing a portfolio’s risk and policymakers concerned about sources of vulnerability. We show how investors can hedge out the cash on firms’ balance sheets when making portfolio choices. Cash generates variation in beta estimates, and we decompose stock betas into components that depend on the firm’s cash holding, return on cash, and cash-hedged return. Common asset pricing premia have large implicit cash positions, and portfolios of cash-hedged premia often have higher Sharpe ratios because of the correlation between firms’ cash returns. We show the value of a dollar increased in 2020, and firms hold cash because they are riskier. (Working Paper no. 22-03).

Aggregate Risk in the Term Structure of Corporate Credit

Higher rates of default can occur when corporations have difficulty accessing short- and long- term credit markets, increasing risks to financial stability. This paper uses credit spread data across different maturities to study what the shape and risk sensitivity of a firm's term structure can tell us about its fragility. Firms that are more financially constrained display a negatively sloped credit spread curve, have short-term spreads that are more sensitive to aggregate conditions, and face heightened rollover risks. Such financing fragility at the short end of the curve can harm a firm's ability to take advantage of investment opportunities (Working Paper no. 22-02).

Financial Intermediary Funding Constraints and Segmented Markets

This working paper examines the role of financial intermediaries, namely authorized participants (APs), in the propagation of shocks across funds that they support and the underlying assets held by those funds. Corporate bond ETF trades by the Federal Reserve through the Secondary Market Corporate Credit Facility (SMCCF) beginning in May 2020 were extremely large and likely alleviated inventory capacity constraints for APs that were counterparties to those transactions. ETFs that were not traded by the Federal Reserve, but overlap in their bond holdings with those traded, exhibit a positive and significant price reaction within minutes of the transaction. Consistent evidence is found for the prices of their underlying bonds. The paper's findings support the view that the inclusion of ETFs in the SMCCF had broader "spillover" effects in stabilizing markets beyond the ETFs directly targeted by the program (Working Paper no. 22-01).

Assessing the Safety of Central Counterparties

Under central clearing, parties to a financial contract enter into two matched contracts with the central counterparty that offset one another. Central clearing protects against defaults among counterparties that could threaten financial stability, but also concentrates the risk of default at the central counterparty. This working paper shows how to estimate the probability that a central counterparty could cover any specified fraction of payment defaults by its members using public disclosure data. The framework supplements conventional risk management approaches predicated on a specific number of member defaults. The paper applies the approach to assessing the safety of a wide range of central counterparties located in different geographical regions and specializing in different asset classes (Working Paper no. 21-02).

Hedge Funds and the Treasury Cash-Futures Disconnect

This paper examines the potential financial stability risks of the Treasury cash-futures basis trade, an arbitrage of pricing differences between the two Treasury markets. Using regulatory data on hedge fund exposures and repurchase agreement (repo) transactions, the paper provides evidence that at its peak the trade was associated with more than half of hedge funds' Treasury positions and a quarter of dealers' repo lending. The trade exposes hedge funds to rollover risk on repo financing and margin risk on the futures, both of which materialized in March 2020. While Treasury market disruptions spurred hedge funds to sell Treasuries, the unwinding of the basis trade was likely a consequence rather than the primary cause of the stress. We present evidence suggesting prompt intervention by the Federal Reserve prevented larger spillovers from the trade into broader Treasury market functioning. (Working Paper no. 21-01)

Credit Risk and the Transmission of Interest Rate Shocks

Unexpected changes in interest rates, often observed through the course of monetary policy, can have a significant effect on corporate credit risk. Using high frequency measures of interest rate surprises surrounding Federal Open Market Committee announcements and daily credit default swap (CDS) spreads, this paper finds a positive, significant relationship between monetary policy shocks and corporate credit risk over the last two decades. One component of the spread affected is compensation related to expected losses in default. The other affected component is the credit risk premium, which measures additional compensation for default risk. Riskier firms, with higher CDS spreads or leverage, or lower market capitalization, are much more sensitive to monetary policy shocks. Among the three measures of firm risk, CDS spreads appear to capture this sensitivity best. High frequency and daily equity returns also exhibit a significant and asymmetric response to policy announcements. (Working Paper no. 20-05)

Central Counterparty Default Waterfalls and Systemic Loss

This paper examines how a central counterparty (CCP) uses a default waterfall to manage and allocate resources to cover defaults of clearing members and clients. A resilient waterfall ensures cleared payments are paid in full and on-time, reducing the threat to financial stability from losses and their spillovers. However, the amount of resources collected and their allocation affect clearing incentives. This paper models and evaluates the trade-offs between resiliency and participation in a credit default swaps market. It finds that the benefits of greater central clearing rates generally dominate the benefits of increased waterfall resources. (Working Paper no. 20-4)

Illiquidity in Intermediate Portfolios: Evidence from Large Hedge Funds

This paper examines whether hedge funds’ returns include a premium that compensates investors for accepting the risk from illiquid asset holdings. It finds that the premium is large and a significant share of risk-adjusted returns. The size of the premium matters for financial stability because it signals investors’ view of the importance of illiquidity risk. (Working Paper no. 20-03)

Leverage and Risk in Hedge Funds

This paper examines the relationship between hedge funds’ use of leverage and their portfolio risk. It finds that more leveraged funds tend to have less volatile returns and less chance of an extreme negative return. More leveraged funds also tend to hold higher quality and more liquid assets. (Working Paper no. 20-02)

The Hedge Fund Industry is Bigger (and has Performed Better) Than You Think

This paper shows that hedge fund industry gross assets exceeded $8.3 trillion, and net assets were at least $5.0 trillion, at year-end 2016. This estimate is around 37 percent larger than the next largest estimate. This paper also shows that funds reporting publicly available data have much lower returns, and much higher net flows, than funds reporting only non-public regulatory data. The outperformance of the non-publicly reporting funds appears to arise entirely from alpha rather than greater exposure to systematic risk factors. (Working Paper no. 20-01)

Cross-Asset Market Order Flow, Liquidity, and Price Discovery

This paper examines the complex intra-day linkages between the U.S. equity securities market and the equity derivatives market. The paper finds a positive, but short-lived, relationship between the two markets’ order flow activities, which relate to the supply, demand, and withdrawal of liquidity between the two markets. The paper also finds that cross-asset market order flow is a key component of liquidity and price discovery, particularly during periods of market volatility. (Working Paper no. 19-04)

The Life of the Counterparty: Shock Propagation in Hedge Fund-Prime Broker Credit Networks

This paper shows the post-crisis hedge fund-prime broker credit network is concentrated among 10 percent of participants. The average fund borrows from three brokers, and the brokers lending the most are highly connected. The paper finds that a liquidity shock to a prime broker results in reduced borrowing by hedge funds due to the broker reducing its supply of credit. Larger, more connected, and better-performing funds, and those that do less over-the-counter trading, are better able to compensate for the reduction in credit from the broker. (Working Paper no. 19-03)

The Effects of the Volcker Rule on Corporate Bond Trading: Evidence from the Underwriting Exemption

This paper examines the impact of the Volcker rule, which bans proprietary trading by commercial banks and their affiliates, with some exceptions. It finds evidence that the rule has increased the cost of liquidity provided by firms it covers, but not decreased the firms’ exposure to liquidity risk. It also finds that the rule has decreased the market share of covered firms. Customers appear to be trading more with non-bank dealers, who are exempt from the Volcker rule but also cannot borrow at the Federal Reserve's discount window. (Working Paper no. 19-02)

Market-Making Costs and Liquidity: Evidence from CDS Markets

This paper examines whether liquidity deteriorated in the single-name credit default swaps market due to regulatory reforms after the 2007-09 financial crisis. It finds evidence of both increased spreads and lower volumes, consistent with the reforms increasing the cost of market-making for bank-dealers. It also finds that transaction prices between dealers and clients have become more dependent on the inventories of individual dealers as interdealer trade has declined. (Working Paper no. 19-01)

Reducing Moral Hazard at the Expense of Market Discipline: The Effectiveness of Double Liability Before and During the Great Depression

This paper examines the impact of double liability on bank risks and depositor safety before and during the Great Depression. Under double liability, shareholders of failing banks lost their initial investments and had to pay up to the par value of their stock to compensate depositors. The paper finds that double liability did not reduce bank risk before the Great Depression, but that deposits were less susceptible to runs. (Working Paper no. 18-06)

OTC Intermediaries

This paper estimates the systemic effects of exit by a key over-the-counter (OTC) intermediary. In the model, risk-averse traders are connected by a core-periphery network. If traders are also averse to concentrated bilateral exposures, then the incomplete network prevents full risk sharing. The impact of the network structure on prices is quantified using proprietary data on all credit default swap transactions in the United States from 2010 to 2013. There are a small number of key OTC intermediaries whose exit can move markets dramatically. Eliminating one of these intermediaries leads to over a 20 percent increase in credit spreads. The Internet Appendix includes extensions of the model. (Working Paper no. 18-05)

Competitive Pay and Excessive Manager Risk-taking

This paper assesses whether compensation plans can drive excessive risk-taking. It develops a model showing that principals offer contracts incentivizing less risky behavior when the market for managers is sluggish. But hot labor markets result in contracts that incentivize risk-taking. The market for executive talent heats up for larger projects and during financial bubbles, when debt funding increases. The results suggest policymakers should consider the impacts of compensation and corporate governance policies on competition for managers. (Working Paper no. 18-02)

The OFR Financial System Vulnerabilities Monitor

This paper describes the purpose, construction, interpretation, and use of the OFR Financial System Vulnerabilities Monitor. The monitor, a heat map of 58 quantitative indicators, is a starting point for assessing vulnerabilities in the U.S. financial system. The OFR launched the monitor in 2017 to help fulfill its mandate to measure and monitor risks to U.S. financial stability. (Working Paper no. 18-01)

Investor Concentration, Flows, and Cash Holdings: Evidence from Hedge Funds

Some hedge funds have a few large investors. Such a concentrated investor base can make a fund vulnerable to unexpected requests for large redemptions. This paper shows that U.S. hedge funds in part account for that risk by holding more cash and liquid assets. These holdings help funds accommodate large outflows, but also result in lower risk-adjusted returns. The Internet Appendix includes methodology details. (Working Paper no. 17-07)

How Safe are Central Counterparties in Derivatives Markets?

How likely is a central counterparty, or CCP, to default after a severe credit shock? This working paper uses credit default swap data to estimate the direct and indirect impacts of a default by CCP counterparties in derivatives trades. It finds that a CCP could be more vulnerable to failure than conventional stress tests have shown. (Working Paper no. 17-06)

The Intersection of U.S. Money Market Mutual Fund Reforms, Bank Liquidity Requirements, and the Federal Home Loan Bank System

After the financial crisis, reforms of money market funds and changes to banks’ liquidity requirements had an unintended consequence of increased Federal Home Loan Banks’ reliance on short-term funding from money market funds to finance longer-term loans and other assets. This increase could make the financial system more vulnerable and pose risks to financial stability. (Working Paper no. 17-05)

Europe’s CoCos Provide a Lesson on Uncertainty

European banks issue contingent convertible bonds. These bonds can force investors to absorb losses when a bank is under stress. The authors find that heightened uncertainty about discretion by banks on when to make payments to investors and by regulators on when to trigger a loss absorption mechanism worsened price declines in a stressed market.

Interbank Contagion: An Agent-based Model Approach to Endogenously Formed Networks

The authors create an agent-based model that can help regulators understand risk in the interbank funding market. Tests of the model against actual bank failures before, during, and after the 2007-09 financial crisis suggest that the market has become more resilient to asset write-downs and liquidity shocks. The model uses balance sheet data from more than 6,600 U.S. banks. (Working Paper no. 16-14)

Bank Networks and Systemic Risk: Evidence from the National Banking Acts

This paper uses unique data to analyze how the national banking acts in 1863 and 1864 reshaped the U.S. bank network in the 1860s. The laws concentrated reserves in New York and regional cities, creating systemically important banks. The paper shows this concentration made contagion more likely if big banks faced economic shocks. (Working Paper no. 16-13)

Contagion in the CDS Market

This paper assesses the risk of contagion in the credit default swap (CDS) market. This risk emerges through the inability of CDS counterparties to make payments during systemic stress. The authors find that the central counterparty contributes significantly less to network contagion than do several peripheral firms that are large net sellers of CDS protection.

Do Higher Capital Standards Always Reduce Bank Risk? The Impact of the Basel Leverage Ratio on the U.S. Triparty Repo Market

This paper examines how risk-taking in the repurchase agreement, or repo, market changed after regulators introduced the supplementary leverage ratio for banks. The paper finds that broker-dealers owned by U.S. bank holding companies now borrow less in the repo market overall after the change, but a larger percentage of the borrowing is backed by more risky collateral.

A Pilot Survey of Agent Securities Lending Activity

A new securities lending survey sheds light on these transactions that help underpin smooth-functioning capital markets. The pilot project by the OFR, Federal Reserve, and staff of the Securities and Exchange Commission shows that participating agents facilitated about $1 trillion in daily securities loans during a three-day period in 2015. Collecting these data on a permanent basis could help regulators identify potential vulnerabilities in a key component of our financial system. (Working Paper no. 16-08)

Does OTC Derivatives Reform Incentivize Central Clearing?

The requirement that standardized over-the-counter derivatives be cleared through central counterparties, or CCPs, is intended in part to create a cost incentive favoring central clearing. This working paper shows that the cost incentive does not necessarily favor central clearing, and when it does, it might be because of insufficient levels of guarantee funds, which banks provide to protect CCPs in the event of CCP member default.

A Map of Collateral Uses and Flows

Collateral is exchanged among market participants to support financial activities, including secured funding, securities lending, securities exchanges, margin lending, derivatives, and clearing. This working paper creates a collateral map to show how collateral moves among bilateral counterparties, triparty banks, and central counterparties, and can spread stress through the financial system. The paper also discusses the recent increase in collateral demand, effects of post-crisis regulation, and collateral-related stress scenarios. (Working Paper no. 16-06)

Does Unusual News Forecast Market Stress?

This paper investigates the use of automated text analysis by computers as a tool for monitoring financial stability. The authors find negative sentiment extracted from tens of thousands of news articles about 50 large financial services companies is useful in forecasting volatility in the stock market. The method, which also considers the "unusualness" of news, may help anticipate stress in the financial system. (Working Paper no. 16-04)

Stopping Contagion with Bailouts: Microevidence from Pennsylvania Bank Networks During the Panic of 1884

This working paper examines how a bailout orchestrated by New York Clearinghouse member banks stopped financial contagion during the Panic of 1884. The private-sector assistance to Metropolitan National Bank, an important correspondent bank for many banks outside New York City, prevented a minor financial crisis in New York from becoming a broad, systemic event, according to the authors' analysis.

Dynamical Macroprudential Stress Testing Using Network Theory

This paper presents a dynamic bipartite network model for a stress test of a banking system's sensitivity to external shocks in individual asset classes. As a case study, the model is applied to investigate the Venezuelan banking system from 1998 to 2013. The model quantifies the sensitivity of bank portfolios to different shock scenarios and identifies systemic vulnerabilities that stem from connectivity and network effects, and their time evolution. The model provides a framework for dynamical macroprudential stress testing. (Working Paper no. 15-12)

Systemwide Commonalities in Market Liquidity

This paper identifies hidden liquidity regimes (high, medium and low) across a broad range of financial markets that can be used for characterizing periods of market stress and identifying underlying predictors of liquidity shocks. This regime could have provided meaningful predictions of liquidity disruptions up to 15 trading days in advance of the 2008 financial crisis. These methods offer a potential framework for monitoring and predicting a systemwide collapse in market liquidity, which could signal a collapse of liquidity in the funding markets as experienced in the financial crisis.

Are the Borrowing Costs of Large Financial Firms Unusual?

This paper examines evidence of a too-big-to-fail subsidy for large financial firms by comparing borrowing costs of large and small firms across industries. The paper finds that larger firms borrow more cheaply in many industries, and this size effect is often largest in nonfinancial industries. These results challenge the notion that expected government bailouts are behind borrowing cost advantages enjoyed by the largest financial firms. (Working Paper no. 15-10)

The Influence of Systemic Importance Indicators on Banks' Credit Default Swap Spreads

This paper examines credit default swap (CDS) spreads in a sample of international banks for evidence of a benefit related to possible measures of systemic importance. The authors find a consistent, statistically significant negative relationship between five-year CDS spreads of banks and nine different systemic importance indicators. The paper shows that the benefit is most pronounced for banks within a certain asset range. Such evidence is weaker for banks identified by regulators as global systemically important banks.

Systemic Risk: The Dynamics under Central Clearing

This paper develops a model for concentration risks that clearing members pose to central counterparties. Over time, larger clearing members crowd out smaller clearing members. Systemic risk is created because high clearing member concentration results in relatively lower lending, higher cost of capital, and increasingly costly hedging. To address this risk, the paper proposes a self-funding systemic risk charge. (Working Paper no. 15-08)

Hidden Illiquidity with Multiple Central Counterparties

This paper focuses on the systemic risks in markets cleared by multiple central counterparties (CCPs). Each CCP charges margins based on the potential impact from the default of a clearing member and subsequent liquidation of a large position. Swaps dealers can split their positions among multiple CCPs, effectively "hiding" potential liquidation costs. A lack of coordination among CCPs can lead to a "race to the bottom" because CCPs with lower perceived liquidation costs can drive competitors out of the market. (Working Paper no. 15-07)

The Effect of Negative Equity on Mortgage Default: Evidence from HAMP PRA

This paper uses data from the Home Affordable Modification Program to examine the impact of principal forgiveness on mortgage default. On average 3.1 percent of loans become delinquent and exit the program each quarter. The authors estimate that the rate would have been 3.8 percent absent principal forgiveness, which averaged 28 percent of the initial mortgage balance. (Working Paper no. 15-06)

Liquidity Risk, Bank Networks, and the Value of Joining the Federal Reserve System

The Federal Reserve System was created to reduce risks related to seasonal swings in loan demand and to stabilize fluctuations in interest rates. Many state-chartered banks chose not to join the system because of the cost of the Federal Reserve's reserve requirements. The inability to attract many state-chartered banks created indirect access to government protection (lender of last resort) without federal regulation. (Working Paper no. 15-05)

Contract as Automaton: The Computational Representation of Financial Agreements

This paper shows that the fundamental legal structure of a well-written financial contract follows a logic that can be formalized mathematically as a "deterministic finite automaton." This allows, for example, automated reasoning to determine whether a contract is internally coherent and complete. The paper illustrates the process by representing a simple loan agreement as an automaton. (Working Paper no. 15-04)

Market Liquidity and Heterogeneity in the Investor Decision Cycle

This paper presents a model of market liquidity in which those who need to sell come into the market with a greater need for immediacy than those who are willing to buy. This is a critical market dynamic behind the illiquidity that arises during market dislocations and crises, when some are in forced-selling mode while others are hesitant to come in and take the other side of the trade.

Are the Federal Reserve's Stress Test Results Predictable?

This paper examines the results of four rounds of stress testing of the largest U.S. bank holding companies, starting in 2009. The data reveal a growing correlation in results from one year to the next, highlighting whether the stress tests in their current form may be losing some of their information value over time. The authors discuss the implications of these patterns and recommend greater diversity in the stress scenarios analyzed. (Working Paper no. 15-02)
