Asian Shares Slip as Markets Reprice Fed Rate Hike Expectations

Asian stocks traded mostly lower on Tuesday as investors contended with rising expectations for Federal Reserve tightening and lingering uncertainty over the conflict in Iran, even as initial peace talks yielded what mediators called “encouraging progress.”

Mixed Markets Amid Dual Pressures

Japan’s Nikkei 225 fell 0.9% to 71,681.29 in Tuesday morning trading, while South Korea’s Kospi dropped 2.8% and Hong Kong’s Hang Seng also declined. Australia’s S&P/ASX 200 edged up marginally, and China’s Shanghai Composite gained 0.2%.apnews

The selling came as the two-year U.S. Treasury yield — the maturity most sensitive to Federal Reserve policy expectations — climbed to 4.24% on Monday, its highest since early 2025. The move extended a surge that began after Fed Chair Kevin Warsh’s inaugural meeting on June 17, when updated projections showed nine officials anticipating a rate hike by year-end and the policy statement dropped language suggesting future cuts.reuters

Markets now price a roughly 72% probability of a quarter-point hike by October. Bloomberg reported earlier this month that traders had fully priced in at least one increase by December after a stronger-than-expected May jobs report pushed shorter-dated yields sharply higher.yahoo

Oil Steadies After US-Iran Progress

Oil prices regained some ground in early Asian trading on Tuesday, with U.S. benchmark crude rising 35 cents to $74.21 per barrel and Brent crude adding 23 cents to $78.13. The recovery followed Monday’s steep drop of more than 2% after Vice President JD Vance said the first round of U.S.-Iran talks in Switzerland had produced a 60-day roadmap toward a final peace deal.yahoo

The U.S. Treasury also issued a temporary general license authorizing the sale of Iranian oil until August 21, a concession tied to Tehran’s agreement to readmit International Atomic Energy Agency inspectors and cooperate on keeping the Strait of Hormuz open.reuters

Wall Street Backdrop

On Wall Street Monday, the S&P 500 fell 0.4%, snapping an 11-week winning streak, as large technology names dragged the broader market lower. Alphabet dropped 5%, Amazon declined 4.7%, and Broadcom lost 4.5%. The Nasdaq Composite tumbled 1.3%, while the Dow Jones Industrial Average bucked the trend with a modest gain.apnews

For Asian investors, the combination of hawkish Fed repricing and a still-uncertain geopolitical outlook left little room for optimism, even as easing oil prices offered some relief to energy-importing economies across the region.
