Zylostar Market Wrap – May 27, 2026

Global markets extended their rally as easing geopolitical tensions in the Middle East, falling oil prices, and continued enthusiasm around artificial intelligence boosted investor sentiment. US equity futures advanced for a fifth consecutive session, with S&P 500 futures rising 0.4% and Nasdaq 100 futures gaining 0.6% after semiconductor stocks pushed Wall Street to fresh record highs.

The AI-driven momentum remained a key market theme, with South Korea’s SK Hynix joining Micron Technology above the $1 trillion market capitalization mark. Meanwhile, Qualcomm secured an agreement with ByteDance to supply chips for AI data centers, highlighting the ongoing expansion of AI infrastructure demand beyond traditional smartphone markets.

European equities also moved higher, led by automakers and consumer stocks, while Treasury yields continued to decline. The US 10-year yield slipped to 4.46% as lower oil prices helped ease concerns over another inflation shock.

Oil markets remained highly volatile amid developments surrounding Iran and the Strait of Hormuz. Brent crude dropped sharply below $97 per barrel on optimism that diplomatic progress between Washington and Tehran could eventually reopen the vital trade route and stabilize energy flows. However, tensions remained elevated after Iran’s IRGC Navy reiterated that passage of “hostile countries” vessels through the Strait of Hormuz remains prohibited.

At the same time, Iran confirmed that 25 commercial vessels had crossed the Strait with Tehran’s permission over the past 24 hours, while US CENTCOM denied reports that American forces had resumed escorting ships through the region. Iran’s President Pezeshkian also stated that Tehran seeks a “dignified framework” to end the conflict following talks with Qatar’s Emir.

In the region, geopolitical risks remained active as the IDF confirmed strikes on more than 150 Hezbollah targets in southern Lebanon and the Beqaa Valley, while Prime Minister Netanyahu said Israeli forces are operating with large ground presence in southern Lebanon.

Federal Reserve officials continued to maintain a cautious tone on inflation. Minneapolis Fed President Kashkari warned it remains “far too soon” to predict the next Fed move, emphasizing that recent US data continues to show inflation risks are higher than expected. Kashkari also warned that inflationary pressures from the Middle East conflict could persist globally and feed into bond markets.

In Asia, the Japanese Yen traded near 159 against the Dollar, keeping intervention concerns alive. Bank of Japan Governor Ueda stated that energy shocks since 2021 helped Japan move away from deflation, though he stressed the country is not experiencing a 1970s-style inflation spiral.

Despite the bullish tone across equity markets, the ECB warned that investors may be underestimating risks tied to geopolitical tensions and rising fiscal pressures, cautioning that financial markets remain vulnerable to a sharp correction.
