A "dollar discount" versus fair value widened significantly after the July FOMC meeting raised credibility concerns. The Fed's recent hawkish delivery helps restore that credibility, potentially unshackling the dollar to rally and close this valuation gap, providing a new baseline of support.

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 argument for a strong US dollar is more robust than a simple bet on higher rates. It's underpinned by multiple factors, including US growth exceptionalism, AI investment, and equity inflows. This provides an asymmetric risk profile with more paths to a positive outcome.

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.

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.

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 U.S. Dollar's value has been driven less by conventional factors like growth expectations and more by an unconventional "risk premium." This premium reflects market reactions to policy uncertainty, such as talk of FX intervention or tariffs. This has caused the dollar to weaken far more than interest rate differentials alone would suggest, creating a significant valuation gap.

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.
