|June 2008||Do Peso Problems Explain the Returns to the Carry Trade?|
with A. Craig Burnside, Martin S. Eichenbaum, Sergio Rebelo: w14054
We study the properties of the carry trade, a currency speculation strategy in which an investor borrows low-interest-rate currencies and lends high-interest-rate currencies. This strategy generates payoffs which are on average large and uncorrelated with traditional risk factors. We argue that these payoffs reflect a peso problem. The underlying peso event features high values of the stochastic discount factor rather than very large negative payoffs.

|August 2006||The Returns to Currency Speculation|
with Craig Burnside, Martin Eichenbaum, Sergio Rebelo: w12489
Currencies that are at a forward premium tend to depreciate. This 'forward-premium puzzle' represents an egregious deviation from uncovered interest parity. We document the properties of returns to currency speculation strategies that exploit this anomaly. We show that these strategies yield high Sharpe ratios which are not a compensation for risk. In practice bid-ask spreads are an increasing function of order size. In addition, there is price pressure, i.e. exchange rates are an increasing function of net order flow. Together these frictions greatly reduce the profitability of currency speculation strategies. In fact, the marginal Sharpe ratio associated with currency speculation can be zero even though the average Sharpe ratio is positive.
