Immediate Impact on the US Dollar and Other Currencies
The single most important development in the foreign exchange (FX) market in the last 12 hours stemmed from Federal Reserve Chair Jerome Powell’s unexpected dovish pivot at the Jackson Hole symposium. Delivered late Friday, August 22, 2025, around 18:00-18:30 UTC, Powell’s speech signaled a significant shift in the Fed’s monetary policy stance. The central bank, according to Powell, is now prepared to consider rate cuts as early as September, citing concerns about potential labor market risks and the need for greater policy flexibility. This marked a dramatic departure from previous Fed guidance, immediately impacting global currency markets.
The immediate impact was a sharp decline in the US Dollar Index (DXY). Within minutes of Powell’s comments, the DXY fell approximately 0.7%, dropping from around 98.40 to below 97.70. This decline reflected a broader weakening of the US dollar against major currencies. EURUSD and GBPUSD both saw significant gains, climbing by approximately 1.5 cents each. Similar upward movements were observed in USDJPY, USDCHF, USDCAD, AUDUSD, and NZDUSD, although the NZDUSD pair experienced an earlier dip due to a separate rate cut by the Reserve Bank of New Zealand (RBNZ) before recovering alongside the broader USD weakness. This decline reflected a broader weakening of the US dollar against major currencies.
Market Reaction and Risk Appetite
The market’s reaction was swift and dramatic. The shift in the Fed’s anticipated policy trajectory, from a stance suggesting continued rate hikes to the possibility of imminent rate cuts, immediately altered investor expectations. This led to a significant surge in risk appetite. Equities rallied significantly, with the S&P 500 gaining over 1.5% by the close of trading. Gold prices also rebounded sharply, gaining approximately $50 from intraday lows. Bond yields also fell, reflecting the market’s increased confidence in a more dovish Fed policy and overall positive risk sentiment. The move was entirely driven by Powell’s policy shift; no new US economic data were released during the period, underscoring the impact of central bank pronouncements.
Probability of a September Rate Cut
The market probability of a September rate cut jumped to 89% following Powell’s comments, a significant increase from the 75% probability estimated just before the speech. This dramatic shift in expectations highlights the influence of central bank communication on market sentiment and FX trading. The overall market reaction was a sharp but orderly adjustment, indicating a substantial re-pricing of the probability of a near-term Fed rate cut. The relatively subdued market volatility throughout August, as reported by analysts at Bank of America, was thus broken by Powell’s surprise announcement.

Impact on Treasury Yields and Other Sovereign Bonds
While specific yield levels for 2-year and 10-year Treasury notes (UST) were not provided in the headlines reviewed, it’s clear that the yields on these key benchmarks declined as a result of the increased expectations for a dovish pivot, reflecting the decreased demand for dollar-denominated assets. The overall impact on other major sovereign bond yields (Bund, Gilt, JGB) was not explicitly reported in the accessible sources.
Conclusion and What to Watch Next
This broad-based dollar weakness and the attendant risk-on sentiment underscores the significance of Powell’s Jackson Hole speech and its immediate impact on global financial markets. The market’s strong response to Powell’s commentary highlights the central role that central bank policy communication plays in shaping investor expectations and driving currency movements.
What to watch next:
- Further market reaction to Powell’s speech and its implications for future Fed policy decisions.
- Upcoming economic data releases that may further influence the Fed’s policy path.
- Any further statements or commentary from Federal Reserve officials in the coming days and weeks clarifying the central bank’s future intentions.
