Real carry factors (adjusted for inflation) are currently outperforming nominal carry factors across G10, EM, and global FX. This dynamic is a pattern historically observed in the early stages of inflationary developments, making it a key forward-looking indicator for macro traders.

While still profitable, FX carry trades have become more cyclical and less of a diversifier. They now exhibit a high correlation (~0.5 beta) with the S&P 500 and offer significantly lower yields (7% vs. 11-12% previously), increasing their risk profile in a potential market downturn.

The success of the current EM FX carry trade isn't driven by wide interest rate differentials, which are not historically high. Instead, the strategy is performing well because a resilient global growth environment is suppressing currency volatility, making it profitable to hold high-yielding currencies against low-yielders.

The market believes the Fed is more likely to ease on weak data than tighten on strong data. This perceived asymmetry in its reaction function effectively cuts off the 'negative tail risk' for global growth, making high-yielding emerging market carry trades a particularly favorable strategy in the current environment.

While the macro environment appears supportive of pro-cyclical currencies, several warning signs could trigger a correction. Notably, the aggressive flattening of the US yield curve (e.g., 5s30s spread breaking below 100bps), even if driven by stronger growth, historically signals caution for high-beta assets and could challenge the current consensus view.

Even if US inflation remains stubbornly high, the US dollar's potential to appreciate is capped by the Federal Reserve's asymmetric reaction function. The Fed is operating under a risk management framework where it is more inclined to ease on economic weakness than to react hawkishly to firm inflation, limiting terminal rate repricing.

Despite record-high economic activity surprises, emerging market currencies (EMFX) are fairly valued, not overextended. This suggests near-term upside for spot prices is limited, making carry returns the more likely driver of performance in this bullish cyclical environment.

While broad emerging market currency indices appear to have stalled, this view is misleading. A deeper look reveals that the "carry theme"—investing in high-yielding currencies funded by low-yielding ones—has fully recovered and continues to perform very strongly, highlighting significant underlying dispersion and opportunity.

The most effective FX expression of the AI theme is through carry strategies, not by picking individual currencies. FX carry shows a high correlation with AI-beneficiary equity sectors like tech and energy. This allows a broad basket of high-yield currencies to outperform as a group, even those without direct AI exposure.
