The U.S. dollar strengthened against major currencies in trading at the New York foreign exchange market on Wednesday (Aug. 26) after the U.S. reported higher-than-expected inflation data, which could support a rate hike by the Federal Reserve. Meanwhile, investors are watching for a speech by Fed Chair Kevin Warsh at the Jackson Hole symposium on Friday. The dollar index rose 0.25% to 99.165. The dollar strengthened against the yen to 159.40 yen from 159.22 yen, and firmed against the Swiss franc to 0.8055 francs from 0.8020 francs. The euro weakened to $1.1651 from $1.1674, and the pound fell to $1.3592 from $1.3646. The U.S. Commerce Department reported that the personal consumption expenditures (PCE) price index rose 3.7% in July year-on-year, higher than the 3.6% forecast by analysts. Core PCE, which excludes food and energy, rose 3.3%, in line with expectations. The latest inflation figures have raised investor concerns that the Fed may raise interest rates. The CME Group's FedWatch Tool indicated that investors assign a 40% probability of a rate hike at the September meeting, compared with 36% before the PCE release. Investors are also awaiting Fed Chair Kevin Warsh's speech at the annual Jackson Hole symposium on Friday, Aug. 28, at 10:00 a.m. U.S. time, or 9:00 p.m. Thai time. Additionally, the Commerce Department released its second estimate for second-quarter GDP, showing growth of 1.5%, unchanged from the initial estimate, and durable goods orders rose 1.1% in July, beating the 0.4% forecast.
