Oil prices remain near $100 per barrel overnight, with Brent crude hovering around $99, as investors assess ongoing geopolitical tensions between the United States and Iran. Recent US military strikes in southern Iran have tempered optimism regarding potential peace talks, despite signals of progress from US officials. Analysts warn that a prolonged disruption of the Strait of Hormuz, a crucial shipping lane, poses the greatest threat to global energy markets in decades, potentially leading to significant oil and LNG supply shortages and impacting global economic growth. This uncertainty underscores the fragility of the energy market and its direct influence on inflation risks and broader economic stability today.
Oil prices stayed elevated in morning trading on May 27 as investors weighed mixed signals over possible U.S.-Iran peace talks against the risk that the conflict could disrupt one of the world’s most important energy corridors.
Brent crude was hovering around $99 a barrel, with crude prices broadly near the $100 mark overnight, after recent U.S. military strikes in southern Iran tempered optimism about diplomatic progress. U.S. officials have signaled movement in talks, but markets remain focused on the possibility of a prolonged disruption in the Strait of Hormuz, a key route for oil and liquefied natural gas shipments.
Analysts cited in the day’s research warned that a closure or extended disruption of the strait would represent one of the most serious global energy supply shocks in decades. Such an outcome could tighten oil and LNG supplies, push up fuel costs and complicate the inflation outlook for major economies already sensitive to energy-driven price pressures.
The pressure is being felt most immediately in currency and rates markets. The Japanese yen traded close to 160 per dollar, a level that has previously drawn intervention from Japanese authorities. Traders are watching whether higher oil prices worsen Japan’s inflation pressures, while Bank of Japan Governor Kazuo Ueda struck a more hawkish tone, warning that an energy shock could become persistent in an environment of elevated inflation expectations and rising wages. That message has reinforced speculation that Japanese rate increases could come earlier than previously expected.
New Zealand’s central bank delivered a similar signal. The Reserve Bank of New Zealand kept its cash rate unchanged on Wednesday after a split vote, but warned that interest rates would probably need to rise sooner and by more than earlier anticipated. Markets responded by narrowing the odds of a rate increase as early as July and pricing in expectations for at least two further hikes by year-end.

The renewed energy shock has not derailed the global equity rally, however. World stocks extended gains overnight, powered by technology shares and continued investor enthusiasm around artificial intelligence. Taiwan’s market capitalization rose to $4.95 trillion, overtaking India to become the world’s fifth-largest stock market. The advance has been driven largely by Taiwan Semiconductor Manufacturing Co., which accounts for roughly 42% of the benchmark TAIEX index and is benefiting from strong demand for AI chips.
South Korea has also participated in the chip-led rally, with the Kospi posting significant gains. Samsung workers approved a substantial bonus deal, supported in part by rising profits in the company’s memory chip division as AI-related investment boosts demand.
Beyond markets, the picture remains uneven. A survey by the European Union Chamber of Commerce in China found tentative improvement in conditions for European companies operating in China, but confidence remains fragile. Firms continue to cite China’s economic slowdown, intense competition, regulatory uncertainty and market-access barriers. Profitability and growth expectations have recovered from last year’s lows, but the chamber said deeper reforms would be needed for a durable recovery in confidence.
In Russia, parliament passed a law allowing banks and other financial institutions, including Sberbank, to operate defense systems and arm staff against drone attacks without direct involvement from special forces. The institutions will bear the costs themselves. The move underscores how the war in Ukraine continues to impose security and operating burdens on parts of Russia’s financial system as drone attacks target infrastructure and facilities inside the country.
For global investors, the morning’s central tension is clear: an AI-driven stock boom is still lifting equity markets, but the oil shock has revived inflation and supply-risk concerns across currencies, central banks and corporate planning. The path of U.S.-Iran tensions, and any threat to energy flows through the Strait of Hormuz, remains the key variable for markets heading into the rest of the day.
