Currency Premia and Global Imbalances
with Pasquale Della Corte and Lucio Sarno.
Review of Financial Studies
We show that a global imbalance risk factor that captures the spread in countries external imbalances and their propensity to issue external liabilities in foreign currency explains the cross-sectional variation in currency excess returns. The economic intuition is simple: net debtor countries offer a currency risk premium to compensate investors willing to finance negative external imbalances because their currencies depreciate in bad times. This mechanism is consistent with exchange rate theory based on capital flows in imperfect financial markets. We also find that the global imbalance factor is priced in cross sections of other major asset markets.

The Two Faces of Cross-Border Banking Flows
with Dennis Reinhardt
IMF Economic Review
We examine the determinants of cross-border interbank and intra-group funding across crisis and non-crisis periods. Using a previously unexplored data set spanning 25 banking systems, we find aggregate intra-group funding is unrelated to fluctuations in either global or local macroeconomic fluctuations, while flightier interbank funding responds pro-cyclically to both worldwide and domestic economic trends. This feature of the data means intra-group funding remains comparatively stable when global conditions deteriorate -- even during the global financial crisis. During `normal' times we find intra-group funding responds counter-cyclically to global interest rate changes, with parent banks using affiliates to o set tighter global funding conditions. More generally, we find intra-group funding has a closer relationship with domestic banking system profitability and solvency, being used to support banks in weaker banking systems during the global financial crisis.

The Value of Volume in Foreign Exchange
with Antonio Gargano and Lucio Sarno
We investigate the information content of foreign exchange (FX) volume using a novel dataset from CLS, the leading FX settlement institution. Consistent with theoretical predictions from models containing liquidity trading and private information, we find that FX volume embeds predictive information for both the time series and cross section of currency returns, which generates substantial economic value. A reversal investment strategy that conditions on past daily volume generates an annualized return of over 19% and a Sharpe ratio of 1.82. We show the returns remain high after accounting for bid-ask spreads, and are unrelated to other common currency strategies and risk factors.

We find a strong link between currency returns and the relative strength of the business cycle. Buying currencies of strong economies and selling currencies of weak economies generates high returns in both the cross section and time series of countries. These returns stem primarily from spot exchange rate predictability, are uncorrelated with common currency strategies, and cannot be understood using traditional risk factors. We also show that a business cycle factor implied by our results is priced in a broad currency cross section. These results contrast with a vast literature that detects no linkages between currency fluctuations and macroeconomic variables.

Currency Hedging in International Portfolios
with Wei Opie
We propose a novel method for dynamically hedging currency exposure that exploits the predictability of global currency factor returns. We evaluate the method against nine leading alternatives and show it generates statistically superior out-of-sample Sharpe ratios and certainty equivalent returns across both international equity and bond portfolios. A risk-averse investor is found willing to pay a high-performance fee to switch to the method from all alternative hedging frameworks. Furthermore we show that a currency portfolio that exploits factor return predictability generates a high Sharpe ratio, and provides global equity and bond investors with larger diversification gains than a portfolio comprising of currency carry, value and momentum strategies.
