The euro tumbled against the U.S. dollar on Thursday, breaching the 1.15 level for the first time in seven weeks, after the Federal Reserve raised interest rates and signaled that another increase could be on the horizon later this year. The currency pair was trading near 1.1474 at 08:38 UTC, marking a decline of approximately 1.2% from the previous session's reading of 1.161, according to Yahoo Finance data. The session low touched 1.1460, underscoring the strength of the greenback across the board.
The move was not isolated to the euro; it reflected a broader surge in the U.S. dollar. The U.S. Dollar Index, which measures the currency against a basket of six major peers, stood near 100.24 at 08:28 UTC, up about 0.8% from 99.46. A Reuters market report attributed the repricing to the Fed's policy path and guidance from Chair Kevin Warsh, who indicated that further tightening could be warranted to contain inflationary pressures.
Two Central Banks Hike, But Guidance Separates Them
The Federal Reserve lifted its target range by 25 basis points to 3.75%–4.00% on Wednesday in a unanimous decision. The accompanying projections revealed a median appropriate year-end federal funds rate of 4.1% for both 2026 and 2027, up from 3.8% and 3.6% respectively in June. A 4.1% year-end midpoint implies one more quarter-point increase from the current range, a signal that markets have priced in with a hawkish tilt.
Meanwhile, the European Central Bank had also tightened its policy earlier this month. On September 10, the ECB raised its deposit rate to 2.50%, effective September 16, and revised its 2026 inflation forecast upward to 3.0%. Despite this, the euro fell, as the ECB's move was already widely anticipated and did not signal further action. The contrast in forward guidance was key: the Fed's promise of another hike outweighed the ECB's completed increase in the eyes of currency traders.
A simple comparison places the midpoint of the Fed's range 137.5 basis points above the ECB deposit rate. While these instruments are not identical, the figure serves as a guide to the carry advantage available on dollars. This differential helps explain why the promise of additional U.S. tightening had a greater impact on the exchange rate than the ECB's already-delivered move.
The Currency Math for Investors
The 1.2% move has real implications for conversion values. At 1.1474, €100,000 buys approximately US$114,740, compared with US$116,100 at 1.1610—a difference of US$1,360. Conversely, US$100,000 converts to roughly €87,154 rather than €86,133. These calculations exclude spreads and fees, but they illustrate why the same market movement benefits euro-based holders of unhedged dollar assets while hurting euro importers who pay in dollars.
However, some analysts caution against expecting a sustained dollar rally. Commonwealth Bank currency strategist Carol Kong told Reuters that the bank was not convinced the decision marked the beginning of a long-term dollar uptrend. Softer U.S. inflation or employment data could remove the extra hike now embedded in projections, while another ECB increase could narrow the expected rate gap.
Technical Outlook
For the immediate price action, 1.15 has shifted from support to a recovery threshold. A sustained move back above that level would weaken the post-Fed break, while failure to recover it—especially with the Dollar Index holding above 100—would leave the seven-week low near 1.1460 exposed to another test. Traders will be watching upcoming U.S. data releases for clues on the Fed's next move.
