August 2017The U.S. Treasury Premium
with Joanne Im, Jesse Schreger: w23759
We quantify the difference in the convenience yield of U.S. Treasuries and the bonds of near default-free sovereigns by measuring the gap between the FX swap-implied dollar yield paid by foreign governments and the U.S. Treasury dollar yield. We call this wedge the “U.S. Treasury Premium.” We find that this premium was approximately 21 basis points for five-year bonds prior to the Global Financial Crisis, increased up to 90 basis points during the crisis, and has disappeared since the crisis with the post-crisis mean at -8 basis points. We show the decline in the premium cannot be explained away by credit risk or FX swap market mispricings. In addition, we present evidence that the relative supply of government bonds in the United States and foreign countries affects the premium.

February 2017Deviations from Covered Interest Rate Parity
with Alexander Tepper, Adrien Verdelhan: w23170
We find that deviations from the covered interest rate parity condition (CIP) imply large, persistent, and systematic arbitrage opportunities in one of the largest asset markets in the world. Contrary to the common view, these deviations for major currencies are not explained away by credit risk or transaction costs. They are particularly strong for forward contracts that appear on the banks' balance sheets at the end of the quarter, pointing to a causal effect of banking regulation on asset prices. The CIP deviations also appear significantly correlated with other fixed-income spreads and with nominal interest rates.

September 2016Sovereign Debt Portfolios, Bond Risks, and the Credibility of Monetary Policy
with Carolin E. Pflueger, Jesse Schreger: w22592
We document that governments whose local currency debt provides them with greater hedging benefits actually issue relatively more foreign currency debt. We introduce two features into a government's debt portfolio choice problem to explain this finding: risk- averse lenders and varying degrees of inflation commitment. A government with imperfect commitment chooses an excessively counter-cyclical inflation policy function ex post, which leads risk-averse lenders to require a risk premium ex ante. This makes local currency debt too expensive from the government's perspective and thereby discourages the government from borrowing in its own currency.
