The US Dollar's trade-weighted index is trading 3-4% cheap compared to where interest rate differentials suggest it should be. This valuation gap implies that the dollar has significant room to appreciate simply to catch up to what rates markets have already priced in, creating an asymmetric upside risk, especially if the Fed delivers a hike.

The Fed's long-standing asymmetric dovish reaction function, which has weighed on the dollar, is neutralizing. Internal dissents and Chairman Powell's commentary signal a more balanced policy stance, which could shift from being a dollar headwind to a tailwind depending on incoming economic data.

The US dollar has been trading cheaply relative to interest rates. A hawkish Fed outcome could trigger a rally as the currency closes this 'misvaluation' gap, even if short-term rates don't reprice significantly. This suggests the dollar has a valuation-based tailwind independent of immediate policy moves.

Analysis of the last five US Federal Reserve hiking cycles reveals a consistent pattern: the dollar appreciates by 4-5% in the window from six months before to one month after the first rate hike. This historical precedent provides a specific timeline and magnitude for anticipating future dollar strength.

Analyzing historical Fed hiking cycles provides a quantitative framework for the dollar's trajectory. A conservative 75 basis point cycle, combined with the dollar's historical beta to rates and its current cheapness versus rate models, suggests a reasonable base case of 3% appreciation.

The US dollar's sharp decline post-FOMC was driven less by the policy decision and more by concerns over the new Fed Chair's credibility in fighting inflation. This concern manifested in a rare "twist steepening" of the 2s/30s Treasury curve, a market dynamic historically negative for the dollar.

Contrary to the belief that the first rate hike marks the dollar's peak, analysis over 30 years shows multiple instances where the dollar appreciated post-hike. This suggests the current cycle may have further room to run, especially given the dollar's relative underperformance leading up to this point.

The current environment is not a repeat of the 2025 dollar debasement. The most damaging scenario for the dollar is rising term premium alongside a Fed with an easing bias. Today, the Fed maintains a hiking bias, preventing the front-end rate collapse needed for a similar sustained dollar sell-off.

The dollar's resilience to disappointing US economic data stems from the market's low starting point for Fed rate hike expectations (less than two hikes priced in). This creates a high bar for further dovish repricing, effectively putting a floor under the currency.
