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.

Volume and Excess Returns in Foreign Exchange

with Antonio Gargano and Lucio Sarno. Latest version: 8 November 2018.

Media coverage: Quant News (1 and 2), published March 16 2018 and August 24 2018

We investigate the information content of foreign exchange (FX) volume using a novel dataset that offers broad coverage of FX volume across spot, forward and swap market instruments. We find that FX volume embeds predictive information for future currency excess returns, which experience stronger reversals when volume decreases. This is consistent with theories of volume which predict that more informed trading is associated with higher volume and weaker reversals in returns. These results have important implications both for dealers seeking to understand the returns to liquidity provision in FX markets, and for global investors pursuing novel sources of return predictability.

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 both in 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. Finally, we propose a mechanism that generates these facts using an international macro-finance model with long-run risk.

Global Currency Hedging with Common Risk Factors

with Wei Opie. Latest version: 15 November 2018.

We propose a novel method for dynamically hedging foreign exchange exposure in international equity and bond portfolios. The method exploits time-series predictability in currency returns that we find emerges from a forecastable component in currency factor returns. The hedging strategy outperforms leading alternative approaches out-of-sample across a large set of performance metrics. Moreover, we find that exploiting the predictability of currency returns via an independent currency portfolio delivers a high risk-adjusted return and provides superior diversification gains to global equity and bond investors relative to currency carry, value, and momentum investment strategies.
