NEW YORK / RankWire.AI / – The U.S. Dollar Index declined by 0.25% to reach 102.27 on Tuesday, October 13, marking a retreat from its highest point in 18 months. The index, which measures the dollar against six key currencies, had risen to 102.61 the previous day. That level represented the highest since April 2025. Declining oil prices and a reassessment of the rally driven by artificial intelligence contributed to the US currency’s decline. Investors also awaited new indications on the direction of US interest rates.

Crude oil prices decreased by 0.86%, settling at $105.75 per barrel during Tuesday’s trading session. Market participants evaluated the potential for additional Russian diesel exports to enter the market, with Moscow indicating it could resume diesel shipments above the levels previously agreed upon by US President Donald Trump in a deal with Russia. Meanwhile, investors are betting that Trump will steer clear of escalation in the Middle East before next month’s midterm elections. Last week, Trump stated that the US would not attack Iran before the elections and on Sunday, referenced an energy ceasefire between Russia and Ukraine.
Recently, the elevated oil prices supported the dollar against both the euro and the yen, as these currencies are linked to economies more heavily dependent on imported oil than the US. According to BNY strategist John Velis, a slight dip in oil prices weakened the dollar modestly. He also noted that earnings reports from major banks were mixed and bond yields traded slightly below recent peaks. Earlier in October, the dollar reached a 17-month high following a surge in Treasury yields.
Euro Gains from Its Lowest Level Since May
On Tuesday, the euro rose by 0.3% to $1.1189, having fallen to $1.11525 the day before, its weakest since May 2025. The upward movement occurred despite gas prices—an essential factor in eurozone inflation—rising once again. Concerns regarding France’s fiscal health also persisted. The euro gained 0.21% against the Japanese yen, reaching 177.32 yen, while the yen itself strengthened by 0.15% to 158.38 per dollar.
The Australian dollar was trading at $0.6979 after the Reserve Bank of Australia released minutes from its latest meeting, which showed unanimous support among board members for a fourth interest rate hike this year. The September increase lifted the official cash rate by 25 basis points to 4.60%. Additionally, analysts expressed growing skepticism about the AI-driven investment narrative fueling demand for US assets. Corpay chief market strategist Karl Schamotta commented that the US exceptionalism trade had become overly extended and was vulnerable to a technical correction.
Federal Reserve Rate Outlook Influences Next Dollar Movements
Market participants shifted their focus to the upcoming September Consumer Price Index, set to be released on Wednesday, as a potential indicator of further Federal Reserve tightening. The CME Group’s FedWatch Tool indicated about an 80% likelihood that rates will remain unchanged at the October 27-28 meeting, compared to a 51% chance a month prior. The market continues to price in roughly 75 basis points of tightening through late 2027. The Fed implemented a rate hike in September. Fed Governor Christopher Waller stated that inflation expectations remain well anchored.
Inflation data released on Wednesday exceeded expectations, pushing the dollar index to another high not seen in 18 months. However, the greenback retreated on Thursday, October 15, falling by 0.44% to 102.00, while the euro rebounded to $1.1210 on the same day. Several Fed officials, including Michelle Bowman and Mary Daly, indicated that the central bank might wait for additional clarity before making further moves. All eyes now turn to Fed Chair Kevin Warsh’s remarks at the IMF-World Bank annual meetings in Bangkok scheduled for Friday.
