NEW YORK / RankWire.AI / – U.S. Dollar Index decreased by 0.25% to 102.27 on Tuesday, October 13, retreating from its highest point in 18 months. The index, which compares the US dollar against a basket of six major currencies, had risen to 102.61 on Monday, marking its peak since April 2025. The decline was influenced by falling oil prices and a reassessment of the rally driven by artificial intelligence enthusiasm. Additionally, investors awaited new cues regarding the future direction of US interest rates.
During Tuesday’s session, crude oil prices dropped 0.86%, settling at $105.75 per barrel. Traders evaluated the potential influx of additional Russian diesel supplies into the market. Moscow indicated it could restore diesel exports beyond the levels previously established by US President Donald Trump in an agreement with Russia. Market participants also anticipated that Trump might avoid escalating tensions in the Middle East before the upcoming midterm elections next month. Last week, Trump stated that the US would not attack Iran before the vote and mentioned an energy ceasefire involving Russia and Ukraine on Sunday.
The elevated cost of oil had recently supported the dollar against the euro and the yen. Both currencies are tied to economies that depend more heavily on imported oil compared to the US. According to BNY strategist John Velis, the slight decline in oil prices contributed to a weaker dollar. He also noted that earnings reports from major banks showed mixed results, while bond yields hovered just below recent highs. Earlier in October, the dollar had reached a 17-month high following a surge in Treasury yields.
Euro recovers from May’s lowest level
On Tuesday, the euro increased by 0.3% to $1.1189. The previous day, it had fallen to $1.11525, the weakest point for the currency since May 2025. This rise occurred despite gas prices, a significant factor influencing inflation within the eurozone, climbing again. Concerns over France’s fiscal stability also persisted. Against the Japanese yen, the euro gained 0.21%, reaching 177.32 yen, while the yen itself strengthened by 0.15% to 158.38 per dollar.
Meanwhile, the Australian dollar was trading at $0.6979 following the release of minutes from the Reserve Bank of Australia’s latest meeting. The document revealed that the board members unanimously supported a fourth interest rate hike this year. The September increase raised the official cash rate by 25 basis points to 4.60%. Analysts are also growing increasingly skeptical of the AI-driven investment narrative supporting demand for US assets. Corpay’s chief market strategist Karl Schamotta commented that the US’s exceptionalism trade had once again become overstretched and vulnerable to a technical correction.
Federal Reserve Rate Expectations Influence Next Dollar Movements
Market participants are now focusing on the upcoming September Consumer Price Index, scheduled for release on Wednesday, to gauge possible additional tightening by the Federal Reserve. According to CME Group’s FedWatch Tool, there is approximately an 80% chance that rates will remain unchanged at the October 27-28 meeting, up from 51% a month earlier. The market also prices in about 75 basis points of rate increases through late 2027. The Fed implemented a rate hike in September. Federal Reserve governor Christopher Waller indicated that inflation expectations are still firmly anchored.
Inflation data released on Wednesday exceeded expectations, pushing the dollar index to an 18-month high. However, on Thursday, October 15, the dollar retreated slightly, falling 0.44% to 102.00. On the same day, the euro rebounded to $1.1210. Statements from Fed officials including Michelle Bowman and Mary Daly suggested that the central bank might wait for further clarity before making additional moves. Attention now shifts to Fed Chair Kevin Warsh’s remarks at the IMF-World Bank annual meetings in Bangkok scheduled for Friday.
