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. (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)

| By Phillip Monin

The OFR Financial Stress Index

The 2007-09 financial crisis showed that stress in the financial system can have devastating effects on the economy. To measure such stress, the OFR has developed a Financial Stress Index. This working paper describes how the index is constructed and how the OFR uses it to monitor financial stability. (Working Paper no. 17-04)

The Complexity of Bank Holding Companies: A New Measurement Approach

Some bank holding companies are very complex, with hundreds or thousands of subsidiaries. This complexity complicates the job of unwinding a failed bank holding company. In this working paper, OFR researchers propose a new way to measure complexity that can support the resolution process after a bank holding company fails. (Working Paper no. 17-03)

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. (Working Paper no. 17-02)

| By Paul Glasserman and Qi Wu

Persistence and Procyclicality in Margin Requirements

This paper describes how to set margin levels for derivatives contracts so that margin calls do not add to market stress during times of instability. Price volatility varies by asset class. Certain qualities of volatility should be taken into account to set the most effective margin levels without adding to market stress. (Working Paper no. 17-01)

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)

| By Mark Paddrik, Sriram Rajan, and H. Peyton Young

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. (Working Paper no. 16-12)

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. (Working Paper no. 16-11)

| By Richard Neuberg, Paul Glasserman, Benjamin Kay, and Sriram Rajan

The Market-implied Probability of European Government Intervention in Distressed Banks

This paper assesses the likelihood of European government support in distressed banks. To measure market expectations of these events, the authors study the credit spread between old credit default swap contracts and new ones with a definition of default linked to government intervention. (Working Paper no. 16-10)

Interconnectedness in the Global Financial Market

This working paper shows how network analysis can facilitate the monitoring of movements by stocks in the global financial system over time. The paper analyzes nearly 4,000 stocks in 15 countries. It concludes that stock returns tend to move together within regions — but not across them — in times of stability, but move in sync globally in times of crisis. (Working Paper no. 16-09)

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)

| By Samim Ghamami and Paul Glasserman

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. (Working Paper no. 16-07)

| By Andrea Aguiar, Richard Bookstaber, Dror Y. Kenett, and Thomas Wipf

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)

The Real Consequences of Bank Mortgage Lending Standards.

This paper describes how mortgage lending standards, as measured by responses to the Federal Reserve's quarterly Senior Loan Officer Opinion Survey, relate to changes in the availability of mortgage loans at banks from 1990 to 2013. The research suggests that the survey's reported changes in credit standards are a leading indicator of the financial industry's vulnerability to shocks. (Working Paper no. 16-05)

| By Harry Mamaysky and Paul Glasserman

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. (Working Paper no. 16-03)

Form PF and Hedge Funds: Risk-measurement Precision for Option Portfolios

This paper examines the precision of Form PF in measuring the risk hedge funds pose to the financial system. Hedge funds and other private funds now file Form PF with the Securities and Exchange Commission. The paper extends the methodology of a 2015 OFR working paper and finds that options significantly weaken the risk-measurement tolerances in Form PF. (Working Paper no. 16-02)

| By Jill Cetina, Mark Paddrik, and Sriram Rajan

Stressed to the Core: Counterparty Concentrations and Systemic Losses in CDS Markets

This paper applies the Federal Reserve's supervisory stress test scenarios to examine the impacts on banks — and the banking system as a whole — from default of their largest counterparties in the credit derivatives markets. The authors find higher loss concentrations for the banking system than for individual firms and potential for large indirect losses when a major counterparty defaults. (Working Paper no. 16-01)

| By Maya Eden and Benjamin Kay

Safe Assets as Commodity Money

This paper examines the systemic implications of the supply of liquid safe assets, such as Treasury bills. The paper explores how liquid safe assets facilitate the trades of risky assets. The paper finds that financial markets may be remarkably resilient to changes in the stock of liquid assets. (Working Paper no. 15-23)

| By Benjamin Munyan

Regulatory Arbitrage in Repo Markets

This paper documents a pattern of foreign-owned broker-dealers reducing their borrowing in the U.S. triparty repo market, a key source of short-term funding in the financial system, at quarter end and immediately returning to the market when a new quarter begins. This activity reduces their capital requirements under the leverage ratio. (Working Paper no. 15-22)

| By Paul Glasserman and H. Peyton Young

Contagion in Financial Networks

This paper surveys the rapidly growing literature about interconnectedness and financial stability. The paper focuses on insights in the literature on the relationship between network structure and the vulnerability of the financial system to contagion. (Working Paper no. 15-21)

| By Jill Cetina and Katherine Gleason

The Difficult Business of Measuring Banks' Liquidity: Understanding the Liquidity Coverage Ratio

Bank regulators adopted a new requirement called the Liquidity Coverage Ratio after the financial crisis to help ensure banks maintain enough liquid assets to cover their financial obligations during times of stress. This paper uses a series of increasingly complex examples to demonstrate issues in analyzing this new liquidity metric. (Working Paper no. 15-20)

| By Jingnan Chen, Mark D. Flood, and Richard B. Sowers

Measuring the Unmeasurable: An Application of Uncertainty Quantification to Financial Portfolios

Uncertainty is a crucial factor in financial stability, but it is notoriously difficult to measure. This working paper extends techniques from engineering to quantify fundamental economic uncertainty, and applies the method to an example of portfolio stress testing. By this measure, uncertainty peaked in late 2008. (Working Paper no. 15-19)

| By Richard Bookstaber and Mark Paddrik

An Agent-based Model for Crisis Liquidity Dynamics

This paper presents an agent-based model for examining price impacts and liquidity dynamics during financial crises, which are often characterized by sharp reductions in liquidity followed by cascades of falling prices. The model highlights the implications of changes in market makers' ability to provide intermediation services and the decision cycles of liquidity demanders versus liquidity suppliers during a crisis. (Working Paper no. 15-18)

| By Viktoria Baklanova, Adam Copeland, and Rebecca McCaughrin

Reference Guide to U.S. Repo and Securities Lending Markets

This paper is a reference guide on U.S. repo and securities lending markets. It discusses the main institutional features of these markets, their vulnerabilities, and data gaps that prevent market participants and regulators from addressing known vulnerabilities. (Working Paper no. 15-17)

| By Paul Glasserman and Linan Yang

Bounding Wrong-Way Risk in Measuring Counterparty Risk

This paper proposes a new method for bounding the impact of "wrong-way risk" on counterparty credit risk measurement for a portfolio of derivatives. Wrong-way risk refers to the possibility that a counterparty's default risk increases with the market value of the exposure. (Working Paper no. 15-16)

Gauging Form PF: Data Tolerances in Regulatory Reporting on Hedge Fund Risk Exposures

This paper examines the precision of Form PF, a regulatory filing introduced after the financial crisis to measure risk exposures for private funds, including hedge funds. The paper finds that Form PF's measurement tolerances are large enough to allow private funds with dissimilar risk profiles to report similar risk measurements to regulators. (Working Paper no. 15-13)

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. (Working Paper no. 15-11)

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. (Working Paper no. 15-09)

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)

| By Paul Glasserman, Ciamac C. Moallemi, and Kai Yuan

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)

| By Mark D. Flood and Oliver R. Goodenough

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. (Working Paper no. 15-03)

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)
