Asian share indices continued to weaken on Tuesday after a sharp advance in crude oil and renewed geopolitical tension between the U.S. and Iran raised fresh inflation concerns and clouded the interest-rate outlook.
U.S. stock futures ticked lower during Asian hours following a steep decline on Wall Street the previous session. Investors were bracing for a key U.S. consumer-price inflation reading due later in the day that could influence the Federal Reserve's policy trajectory.
Oil moves and geopolitical drivers
Oil prices pressed higher, extending a 10% rally from Monday, after U.S. President Donald Trump said Washington would reinstate a blockade on Iranian shipping and impose a 20% charge on cargo transiting the Strait of Hormuz. Renewed U.S. military strikes on Iran further increased worries about possible disruptions to global crude supplies, contributing to the rise in prices toward one-month highs.
The jump in oil rekindled concerns that inflation could remain elevated, which prompted traders to pare back expectations for monetary easing and to reassess the likely path for rates.
Policy signals and market expectations
Comments from Federal Reserve Governor Christopher Waller were viewed as hawkish by markets, and futures markets moved to price in a greater chance of a Fed interest-rate increase later this month. The combination of higher oil and hawkish central-bank rhetoric pushed investors to increase bets on a July rate hike.
Regional market moves
South Korea's KOSPI led declines in the region, falling 2.5% and extending sharp losses from the previous session, as semiconductor stocks remained volatile following a sharp decline in SK hynix's U.S.-listed shares overnight. Japan's Nikkei 225 slipped 1%, while the broader TOPIX index traded largely flat. China's Shanghai Composite was mostly unchanged, and the blue-chip Shanghai Shenzhen CSI 300 rose 0.5%. Hong Kong's Hang Seng was muted.
Elsewhere, Australia's S&P/ASX 200 dipped 0.5%, Singapore's Straits Times Index fell 1%, and futures tied to India's Nifty 50 were largely steady.
China trade data and broader demand trends
Tuesday's data showed China's exports and imports grew much faster than expected in June. The report attributed the resilience to robust global demand for artificial intelligence-related products and other technology goods, which helped offset mounting geopolitical headwinds.
Near-term focus
With oil pushing higher and central-bank commentary tilting hawkish, market participants were focused on the U.S. consumer price inflation report due later in the day for fresh clues on policy. The data is expected to be closely watched for indications of whether current inflationary pressures will persist and how central banks may respond.
