The Overnight Drift in U.S. Equity Returns
Since the advent of electronic trading in the late 1990s, S&P 500 futures have traded close to 24 hours a day. In this post, which draws on our recent Staff Report, we document that holding U.S. equity futures overnight has earned a large positive return during the opening hours of European markets. The largest positive returns in the 1998–2019 sample have accrued between 2 a.m. and 3 a.m. U.S. Eastern time—the opening of European stock markets—and averaged 3.6 percent on an annualized basis, a phenomenon we call the overnight drift.

800,000 Years of Climate Risk
We use a long history of global temperature and atmospheric carbon dioxide (CO2) concentration to estimate the conditional joint evolution of temperature and CO2 at a millennial frequency. We document three basic facts. First, the temperature–CO2 dynamics are non-linear, so that large deviations in either temperature or CO2 concentrations take a long time to correct–on the scale of multiple millennia. Second, the joint dynamics of temperature and CO2 concentrations exhibit multimodality around historical turning points in temperature and concentration cycles, so that prior to the start of ...

Trends in credit market arbitrage
Market participants and policymakers alike were surprised by the large, prolonged dislocations in credit market arbitrage trades during the second half of 2015 and the first quarter of 2016. In this paper, we examine three explanations proposed by market participants: increased idiosyncratic risks, strategic positioning by some market participants, and regulatory changes. We find some evidence of increased idiosyncratic risk during the relevant period but limited evidence of asset managers changing their positioning in derivative products. While we cannot quantify the contribution of these ...

Counterparty risk in material supply contracts
This paper explores the sources of counterparty risk in material supply relationships. Using long-term supply contracts collected from SEC filings, we test whether three sources of counterparty risk?financial exposure, product quality risk, and redeployability risk?are priced in the equity returns of linked firms. Our results show that equity holders require compensation for exposure to all three sources of risk. Specifically, offering trade credit to counterparties and investing in relationship-specific assets increase the firm?s exposure to counterparty risk. Further, we show that contracts ...

Liquidity Effects of Post-Crisis Regulatory Reform
The post-crisis regulatory reform efforts to improve capital and liquidity positions of regulated institutions provide incentives for banks to change not only the structure of their own balance sheets but also how they interact with their customers and other market participants more generally. A 2015 PwC study on global financial market liquidity, for example, noted that “[a]s banks respond to the new regulatory environment, they have sought to make more efficient use of capital and liquidity resources, by reducing the markets they serve and streamlining their operations.” In this blog ...

The Long and Short of It: The Post-Crisis Corporate CDS Market
The authors establish key stylized facts about the post-crisis evolution of trading and pricing of credit default swaps. Using supervisory contract-level data, they show that dealers became net buyers of credit protection starting in the second half of 2014, both through reducing the amount of protection they sell in the single-name market and switching to buying protection in the index market. More generally, they argue that considering simultaneous positions in different types of credit derivatives is crucial for understanding institutions’ decisions to participate in these markets and ...

Vulnerable growth
We study the conditional distribution of GDP growth as a function of economic and financial conditions. Deteriorating financial conditions are associated with an increase in the conditional volatility and a decline in the conditional mean of GDP growth, leading the lower quantiles of GDP growth to vary with financial conditions and the upper quantiles to be stable over time: Upside risks to GDP growth are low in most periods while downside risks increase as financial conditions become tighter. We argue that amplification mechanisms in the financial sector generate the observed growth ...

Counterparty Risk in Material Supply Contracts
Forming long-term partnerships with customers and suppliers often creates a competitive advantage for firms because it permits resource sharing, eases financial constraints, and encourages investment in relationship-specific capital. While these relationships can be beneficial, they also increase firms? exposure to their counterparties? risk. In a recent Staff Report, Anna Costello of MIT and I study two important and unanswered questions about supply relationships. First, what specific characteristics of the trade relationship make a firm more vulnerable to adverse spillovers from their ...

No Good Deals—No Bad Models
The recent financial crisis has highlighted the significance of unhedgable, illiquid positions in complex securities for individual financial institutions and for the global financial system as a whole. Indeed, the Basel Committee on Banking Supervision notes that "One of the key lessons of the crisis has been the need to strengthen the risk coverage of the capital framework. Failure to capture major on- and off-balance sheet risks, as well as derivative related exposures, was a key destabilizing factor during the crisis."

Intermediary Leverage Cycles and Financial Stability
The financial crisis of 2007-09 highlighted the central role that financial intermediaries play in the propagation and amplification of shocks. Intermediaries increase leverage during the boom, which then makes them more vulnerable to adverse economic developments. In this post, we review evidence on the balance-sheet behavior of financial intermediaries and describe a channel that allows intermediaries to increase leverage during booms when asset market volatility tends to be low, which in turn forces them to dramatically reduce leverage once volatility increases. As shown during the ...
