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.

J.P. Morgan maintains a constructive stance on the Eurodollar due to its asymmetric response to Fed pricing. The currency strengthens more when the Fed's terminal rate is priced lower but shows stickiness when it's priced higher, creating a favorable risk-reward profile for bullish positions despite lowered upside targets.
Contrary to fears of a spike, a major rise in 10-year Treasury yields is unlikely. The current wide gap between long-term yields and the Fed's lower policy rate—a multi-year anomaly—makes these bonds increasingly attractive to buyers. This dynamic creates a natural ceiling on how high long-term rates can go.
A recent global fixed income sell-off was not triggered by a single U.S. event but by a cascade of disparate actions from central banks and data releases in smaller economies like Australia, New Zealand, and Japan. This decentralized shift is an unusual dynamic for markets, leading to dollar weakness.
Due to massive government debt, the Fed's tools work paradoxically. Raising rates increases the deficit via higher interest payments, which is stimulative. Cutting rates is also inherently stimulative. The Fed is no longer controlling inflation but merely choosing the path through which it occurs.
Policymakers can maintain market stability as long as inflation volatility remains low, even if the absolute level is above target. A spike in CPI volatility is the true signal that breaks the system, forces a policy response, and makes long-term macro views suddenly relevant.
The Fed expects inflation from tariffs to be a temporary phenomenon, peaking in Q1 before subsiding. This view allows policymakers to "look through" the temporary price spike and focus on what they see as a more pressing risk: a cooling labor market. This trade-off is described as the "cost of providing insurance to the labor market."
The disinflationary impact from goods prices has largely run its course in emerging markets. The remaining inflation is concentrated in the service sector, which is sticky and less responsive to monetary policy. This structural shift means the broad rate-cutting cycle is nearing its end, as central banks have limited tools to address services inflation.
The US dollar's rally has a natural ceiling because the government shutdown is withholding crucial growth and labor market data. Without this data, markets lack the conviction to push the dollar significantly higher, making the trend self-limiting.
The U.S. government's debt is so large that the Federal Reserve is trapped. Raising interest rates would trigger a government default, while cutting them would further inflate the 'everything bubble.' Either path leads to a systemic crisis, a situation economists call 'fiscal dominance.'
Fed Chair Powell's hawkish tone caused a short-term dollar rally by pushing back on a December rate cut. However, the market has not fundamentally re-evaluated the Fed's terminal rate, suggesting the dollar's upward potential from this single factor is capped as the core long-term trajectory remains unchanged.
