We develop a model in which capital moves quickly within an asset class, but slowly between asset classes. While most investors specialize in a single asset class, a handful of generalists can gradually reallocate capital across markets. Upon the arrival of a large supply shock, prices of risk in the directly impacted asset class become disconnected from those in others. Over the long run, capital ‡ows between markets and prices of risk become more closely aligned. While prices in the directly impacted market initially overreact to the supply shock, we show that prices in related asset classes underreact under plausible conditions. We use the model to assess event-study evidence on the impact of recent large-scale asset purchases by central banks.

This paper examines the joint determination of deviations in long-term covered interest rate parity and dierences in the credit spread of bonds of similar risk but dierent currency denomination. These two pricing anomalies are highly aligned in both the time series and the cross-section of currencies. The sum of these two pricing deviationsthe corporate basisrepresents the currency-hedged borrowing cost difference between currency regions and explains up to a third of the variation in the aggregate corporate debt issuance ow. I show that arbitrage aimed at exploiting one type of security anomaly can give rise to the other.

We characterize how U.S. global systemically important banks (GSIBs) supply shortterm dollar liquidity in repo and foreign exchange swap markets in the post-Global Financial Crisis regulatory environment and serve as the "lenders-of-second-to-lastresort". Using daily supervisory bank balance sheet information, we find that U.S. GSIBs modestly increase their dollar liquidity provision in response to dollar funding shortages, particularly at period-ends, when the U.S. Treasury General Account balance increases, and during the balance sheet taper of the Federal Reserve. The increase in the dollar liquidity provision is mainly financed by reducing excess reserve balances at the Federal Reserve. Intra-firm transfers between depository institutions and broker-dealer subsidiaries within the same bank holding company are crucial to this type of "reserve-draining" intermediation. Finally, we discuss factors that contributed to the repo spike in September 2019 and the subsequent response of U.S. GSIBs to recent policy interventions by the Federal Reserve.
