Dollar Carry Trade: Timing the Dollar with Currency Forward Discounts

Summary

The dollar carry trade uses the average forward discount of a basket of developed-market currencies relative to the US three-month Treasury rate to choose a currency position. If the US rate exceeds the basket’s average forward discount, the strategy goes long the dollar and short the basket; if it is lower, it reverses those positions. The basket is equally weighted, and the portfolio is rebalanced monthly. The document notes that average three-month currency rates can substitute for forward discounts.

The cited research interprets the signal as capturing compensation for US-specific risk, which can vary over time and differ from the global risk exposure represented by conventional currency carry. The source abstract reports return predictability and low correlation with conventional carry, while related papers give mixed and broader evidence on currency risk factors. The page does not provide enough detail to verify implementation costs or a full performance history, and it explicitly says the strategy’s equity-hedging behavior is unknown without further testing.

Key ideas

• The signal compares the US three-month Treasury rate with the equal-weighted average forward discount of developed-market currencies.
• The strategy takes the opposite side of the currency basket when the US rate is above or below that average.
• Positions are rebalanced monthly, and average three-month currency rates are offered as an alternative signal input.
• The cited explanation links the strategy to time-varying compensation for bearing US-specific risk.
• The document does not establish whether the strategy hedges equities during market crises.
