Unlike the 2023 Treasury surprise that occurred when financial conditions were tight, today's actions have less potential to drive a major dollar sell-off. With Financial Condition Indexes (FCIs) already at their loosest levels in years, there is little room for further policy-driven easing to weaken the currency.

The typical pattern preceding the first Federal Reserve rate hike in a cycle involves the dollar strengthening significantly in the six months prior. This historical precedent provides a clear, tactical playbook for being long the dollar ahead of anticipated tightening.

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.

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.

The combination of restrictive trade policy, locked-in fiscal spending, and a Federal Reserve prioritizing growth over inflation control creates a durable trend toward a weaker U.S. dollar. This environment also suggests longer-term bond yields will remain elevated.

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 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.

Despite the dovish perception of the recent Fed meeting, a sustained US dollar collapse is unlikely. Several offsetting factors provide support: the prospect of a December rate hike, superior carry versus other currencies, strong labor market data, and geopolitical risks like rising oil prices which favor the dollar as a safe haven.
