U.S. Dollar Drops After Four Weeks of Gains as Market Expectations Shift
Washington, Sunday, 18 October 2026.
On October 18, 2026, the U.S. dollar experienced its first weekly decline in over a month, falling as investors overwhelmingly bet the Federal Reserve will hold interest rates steady.
Weekly Performance and Technical Reversal
The U.S. Dollar Index (DXY) settled at 101.87 points on October 18, 2026, marking a decisive shift in momentum after a sustained period of growth [1]. This closing price represents a weekly decline of 0.35% for the week ending October 17, 2026, effectively ending a four-week streak of gains [1]. The pullback follows a recent high near 103.00 points reached on October 15, 2026, which was the highest level recorded since April 2025 [5]. Market analysts had been monitoring the 101.8 to 102.0 level for potential buyer support, a threshold that remains critical as the index fluctuates below 102 points [4]. Prior to this decline, the index had shown strength earlier in the month, rising 0.2% toward an 18-month high as of October 12, 2026 [2]. The recent volatility underscores the sensitivity of the greenback to shifting macroeconomic data and trader sentiment during mid-October 2026 [6].
Federal Reserve Policy Expectations
Market consensus indicates an 83% probability that the Federal Reserve will maintain current interest rates at their scheduled meeting in late October 2026 [1]. This expectation has risen significantly from approximately 49% in mid-September 2026, reflecting a stabilization in investor outlook regarding monetary policy [1]. Federal Reserve Chair Kevin Warsh contributed to this sentiment through remarks made during a Fireside Chat with the International Monetary Fund, where he noted witnessing structural growth and an investment surge [7]. Chair Warsh confirmed that future monetary policy determinations would be assessed at upcoming meetings in October and December 2026 [7]. Despite higher-than-expected U.S. inflation figures reported earlier in the month, the belief persists that borrowing costs will remain steady in the immediate term [1][5]. Government data revealed a 0.3% increase in core inflation for September, characterized as broad-based, which initially supported dollar strength before the latest reversal [2].
Global Economic Implications and Trading Ranges
The stabilization of the U.S. dollar has direct implications for international currency demand and foreign exchange exposure for global operations [1]. In Vietnam, the USD/VND exchange rate remained stable domestically on October 18, 2026, with commercial bank selling rates ranging between 26,060 and 26,096 VND/USD [1]. Market participants are closely monitoring whether the DXY remains below 102 points as trading resumes, alongside the State Bank of Vietnam’s central exchange rate settings [1]. Technical analysis indicates a primary resistance level for the DXY at 102.95, representing the recent cycle high [5]. A clear break above this resistance level is projected to facilitate a stronger bullish extension for the U.S. Dollar, whereas failure to reclaim this ground may sustain the current downward pressure [5]. The FXS Fed Sentiment Index remained unchanged at 127.51, suggesting a consistent hawkish territory despite the index’s decline [7].
