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 ...

Trends in Arbitrage-Based Measures of Bond Liquidity
Corporate bonds are an important source of funding for public corporations in the United States. When these bonds cannot be easily traded in secondary markets or when investors cannot easily hedge their bond positions in derivatives markets, the issuance costs to corporations increase, leading to higher overall funding costs. In this post, we examine recent trends in arbitrage-based measures of liquidity in corporate bond and credit default swap (CDS) markets and evaluate potential explanations for the deterioration in these measures that occurred between the middle of 2015 and early 2016.

Bank-intermediated arbitrage
We argue that post-crisis banking regulations pass through from regulated institutions to unregulated arbitrageurs. We document that, once post-crisis regulations bind post 2014, hedge funds use a larger number of prime brokers and diversify away from GSIB-affiliated prime brokers, and that the match to such prime brokers is more fragile. Tighter regulatory constraints disincentivize regulated institutions not only to engage in arbitrage activity themselves but also to provide leverage to other arbitrageurs. Indeed, we show that the maximum leverage allowed and the implied return on basis ...

Negative swap spreads
Market participants have been surprised by the decline of U.S. interest rate swap rates relative to Treasury yields of equal maturity over the past two years, with interest rate swap spreads becoming negative for many maturities. This movement of swap spreads into negative territory has been attributed anecdotally to idiosyncratic factors such as changes in foreign reserve balances and liability duration management by corporations. However, we argue in this article that regulatory changes affected the willingness of supervised institutions to absorb shocks. In particular, we find that ...

Bank-Intermediated Arbitrage
Since the 2007-09 financial crisis, the prices of closely related assets have shown persistent deviations—so-called basis spreads. Because such disparities create apparent profit opportunities, the question arises of why they are not arbitraged away. In a recent Staff Report, we argue that post-crisis changes to regulation and market structure have increased the costs to banks of participating in spread-narrowing trades, creating limits to arbitrage. In addition, although one might expect hedge funds to act as arbitrageurs, we find evidence that post-crisis regulation affects not only the ...

Trends in credit basis spreads
Market participants and policymakers were surprised by the large, prolonged dislocations in credit market basis trades during the second half of 2015 and the first quarter of 2016. In this article, we examine three explanations proposed by market participants: increased idiosyncratic risks, strategic positioning by asset managers, 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. Although we cannot quantify the contribution of these two channels to ...

Credit Market Arbitrage and Regulatory Leverage
In a companion post, we examined the recent trends in arbitraged-based measures of liquidity in the cash bond and credit default swap (CDS) markets. In this post, we turn to the mechanics of the CDS-bond arbitrage trade and explore how the costs and profitability of such trades might be affected by the finalization of the supplementary leverage ratio (SLR) rule in September 2014.

How Has Post-Crisis Banking Regulation Affected Hedge Funds and Prime Brokers?
“Arbitrageurs” such as hedge funds play a key role in the efficiency of financial markets. They compare closely related assets, then buy the relatively cheap one and sell the relatively expensive one, thereby driving the prices of the assets closer together. For executing trades and other services, hedge funds rely on prime brokers and broker-dealers. In a previous Liberty Street Economics blog post, we argued that post-crisis changes to regulation and market structure have increased the costs of arbitrage activity, potentially contributing to the persistent deviations in the prices of ...
