Abstract: This paper uncovers that 30% of trading in interbank funding markets is driven by banks’ usage of securitized “repo” lending to deliver on their obligations in bond markets, suggesting widespread leveraging and short-selling activity. I exploit a regulatory reform that shortened the settlement cycle of fixed income markets to identify a class of agents routinely using repo to source cash and securities in time for settlement; their trading patterns shifted instantly as they moved to a correspondingly shorter repo maturity. I demonstrate that this dynamic distorts both the term structure of interest rates as well as the transmission of the monetary policy rate. This paper thus identifies a preferred habitat effect at the core of interbank funding markets, a notable finding given the ultra-short-term nature of this segment.

Abstract: Deviations from covered interest rate parity (CIP) have been attributed to limits to arbitrage, but trading volumes surge during periods of no-arbitrage violations. We show that such distortions are caused by constraints on non-U.S. agents’ access to wholesale U.S. dollar markets, and thus reflect a premium for obtaining unencumbered synthetic dollar funding. Three main findings emerge. First, non-U.S. banks substitute secured USD borrowing with foreign exchange swaps to comply with regulatory requirements. Second, the cross-currency basis reflects the shadow costs imposed on non-U.S. agents for borrowing in U.S. wholesale segments. Third, U.S. dealers extract rents on dollar provision; the costs are ultimately passed on to the real economy, with non-U.S. customers paying an additional $10.4 billion in hedging costs. Our study highlights how intermediary constraints impact interconnected money markets and drive segmentation in global dollar funding.
Foreign Exchange Swap Liquidity
with Peteris Kloks and Angelo Ranaldo. Swiss Finance Institute Research Paper No. 23-22, SSRN.
Conferences: 2023 SFI Research Days in Gerzensee, IFABS 2023 Oxford, 29th Annual Meeting of the German Finance Association (DGF), 18th Central Bank Conference on the Microstructure of Financial Markets at the Federal Reserve Board, 2024 BEAR Conference on the Prudential Framework, Bank of England, IMF, Morgan Stanley, Queen Mary University of London, University of St.Gallen, University of Zurich. Media coverage: FX Markets, Risk.net.
Abstract: We present the first comprehensive examination of liquidity in the global foreign exchange (FX) swap market, assessing both its tightness and depth. Three main findings emerge. First, as compared with spot, FX swap liquidity conditions are highly fragmented and more unstable. Second, constrained dealers reduce liquidity supply around quarter-end reporting periods. However, while this would imply a decline in trading activity, we find that volumes surge. A novel demand channel for short-term funding jointly explains volume and liquidity dynamics during these periods. Third, we show a strong and consistent relationship between illiquidity and deviations from the law of one price.
