- Asian markets traded cautiously as U.S.-Iran talks faced renewed obstacles.
- Treasury yields rose, increasing expectations of possible Federal Reserve rate hikes.
- Japanese yen hit a 40-year low against the dollar, prompting intervention concerns.
- Oil prices edged higher as Strait of Hormuz negotiations remained unresolved.
Asian markets opened the third quarter on a cautious note Wednesday as investors weighed renewed uncertainty over U.S.-Iran diplomacy, rising U.S. Treasury yields and the prospect of additional Federal Reserve rate hikes. The stronger dollar pushed the Japanese yen to a fresh 40-year low, keeping traders alert for possible currency intervention by Tokyo.
Market sentiment also reflected caution ahead of remarks from Federal Reserve Chair Kevin Warsh and Thursday’s U.S. employment report, both of which could influence expectations for the Fed’s July policy meeting. While technology stocks continued to support equities after a strong second quarter, higher borrowing costs and geopolitical risks limited broader risk appetite.
Japan’s Nikkei 225 rose 1%, extending gains after rallying 37% during the second quarter, while South Korea’s Kospi fell 1.4% following its 68% surge over the same period. MSCI’s broadest Asia-Pacific index outside Japan was little changed. European stock futures were broadly flat, while U.S. futures edged lower after Wall Street recorded its strongest quarterly performance since 2020, led by semiconductor stocks.
Fed Rate Expectations and Treasury Yields Pressure Global Markets
Investors grew more cautious after U.S. Treasury yields climbed sharply overnight, with the benchmark 10-year Treasury yield rising nearly 9 basis points to 4.55%, reflecting expectations that the Federal Reserve could keep monetary policy restrictive for longer.
According to CME Group’s FedWatch Tool, futures markets imply a 33% probability of a Fed rate increase at the July meeting and about a 70% chance of a hike by September. The reassessment follows resilient U.S. economic data that has complicated expectations for monetary easing.
Attention now turns to Fed Chair Kevin Warsh’s appearance at the European Central Bank forum and Thursday’s U.S. nonfarm payrolls report, both of which could provide further direction for interest-rate expectations and global financial markets.
U.S.-Iran Diplomatic Deadlock Supports Oil Prices
Geopolitical uncertainty also remained in focus after Tehran said it would not meet senior U.S. envoys who had travelled to the region, underscoring continued differences over a framework that would fully reopen the Strait of Hormuz.
The Strait of Hormuz remains one of the world’s most strategically important energy corridors, with roughly 20 million barrels of crude oil and petroleum products per day – around 20% of global petroleum liquids consumption – passing through the waterway in 2024, according to the U.S. Energy Information Administration (EIA).
Brent crude futures rose 0.5% to $73.31 a barrel, while U.S. West Texas Intermediate crude gained 0.7% to $69.96. Prices remain well below Brent’s May peak of $126.41, reflecting improved supply conditions despite ongoing geopolitical risks.
Yen Hits Four-Decade Low as Dollar Strength Dominates
The U.S. dollar climbed to 162.715 yen, its strongest level against the Japanese currency in approximately four decades, renewing speculation that Japanese authorities could intervene in foreign exchange markets.
Japan’s Ministry of Finance previously spent nearly 12 trillion yen (about $75 billion) on currency intervention during April and May in an effort to stabilize the yen, though the impact proved temporary.
Analysts at Deutsche Bank said the latest move reflected broad-based dollar strength rather than exceptional yen weakness. They noted Japan continues to benefit from lower global energy prices as a major net importer, while narrowing real yield differentials suggest the yen’s depreciation could become more limited if U.S. dollar momentum eases.
Technology Earnings Seen as Key Test for Equity Rally
Despite rising bond yields, investors continue to expect strong corporate earnings to support equity valuations, particularly in the technology sector that has driven global markets higher throughout 2026.
The Philadelphia Semiconductor Index surged 88% during the second quarter, helping Wall Street post its strongest quarterly gain since 2020. Major U.S. banks will begin reporting earnings in mid-July, followed by large technology companies whose results are expected to determine whether current valuations remain justified.
Market participants will closely monitor corporate guidance alongside central bank policy signals to assess whether robust earnings can offset the headwinds from elevated interest rates and ongoing geopolitical uncertainty.
