    U.S. dollar trades near multi-month lows; oil rises above $90

The U.S. dollar remained near multi-month lows against major currencies on Tuesday as investors reduced expectations for an interest rate hike by the Federal Reserve. This market shift follows recent data indicating a softening U.S. economy, though escalating tensions in the Middle East have limited the dollar's decline through safe-haven buying.

The shift in market sentiment follows a series of economic indicators from the past few weeks, including unexpected job losses in July and mild inflation reports. These factors have led many market participants to reconsider the likelihood of the Federal Reserve, the U.S. central bank, raising rates in the near term. Most economists surveyed by Reuters over the past week expect the Fed to keep rates unchanged through the end of the year.

According to the CME FedWatch tool, traders now estimate a 35% probability of a rate hike at the Federal Reserve's September meeting, a decrease from the 52.2% chance estimated one week ago. In currency markets, the euro traded at $1.1571 on Tuesday after reaching a two-month high on Monday, while the British pound stood at $1.3534. Meanwhile, the Japanese yen was valued at 159.72 per dollar as investors look toward a Bank of Japan meeting next month where a rate increase is expected.

The scale of this shift is reflected in the global energy and bond markets. Brent crude futures rose to $91.38 a barrel, a cost that typically translates to higher prices at the gasoline pump within weeks. This price pressure is exacerbated by the effective closure of the Strait of Hormuz, a critical global shipping lane where traffic has dropped to single digits. For an average household, sustained oil prices above $90 a barrel can increase monthly commuting and heating expenses. Additionally, the yield on 30-year U.S. Treasury bonds has reached its highest level since 2007, a benchmark that influences the long-term interest rates banks charge for home mortgages.

The broader impact involves a potential return of high inflation due to supply shocks. A senior Iranian official stated the country would move to a "fully offensive" posture as peace talks stalled and the U.S. declined to extend a June ceasefire. If the conflict continues to disrupt shipping and energy supplies, the progress made in cooling inflation over the past year could be reversed. Investors and policymakers are now focused on the Federal Reserve's September meeting and the Bank of Japan's upcoming rate decision to see how central banks will balance recession risks against the inflationary pressure of $90-per-barrel oil.
