Global Stocks Mixed as Japan and South Korea Hit Record Highs Following U.S.-Iran Peace Agreement

BY COMFORT OGBONNA

Global stock markets delivered a mixed performance on Thursday, with benchmark indexes in Japan and South Korea climbing to fresh record highs as investors welcomed a newly signed agreement between the United States and Iran aimed at ending months of conflict and reducing tensions in the Middle East.

The positive sentiment across much of Asia reflected growing optimism that the agreement could help stabilize global energy markets and ease concerns over supply disruptions that had weighed on the global economy throughout the conflict. Investors also viewed the deal as a potential boost for economic growth, particularly in countries heavily dependent on imported energy.

Under the agreement signed by leaders from both nations, the United States and Iran have committed to a permanent cessation of hostilities while launching a 60-day negotiation period intended to produce a broader and more comprehensive accord regarding Iran’s nuclear program. As part of the initial framework, Tehran agreed to dilute portions of its stockpile of highly enriched uranium, while Washington moved to lift sanctions that had significantly restricted Iran’s oil exports. The easing of sanctions is expected to allow Iran to increase crude shipments to global markets, potentially improving supply conditions and helping to moderate energy prices.

While the diplomatic breakthrough boosted investor confidence in Asia, markets remained cautious after a weak session on Wall Street the previous day. U.S. stocks retreated sharply after the Federal Reserve signaled that interest rates could remain elevated longer than previously expected. Updated projections released by policymakers showed that nearly half of Federal Reserve officials anticipate at least one interest rate increase in 2026 as inflation remains a concern.

Despite the uncertainty surrounding monetary policy, U.S. stock futures pointed higher ahead of Thursday’s opening bell. Futures tied to the S&P 500 gained 0.9%, while Dow Jones Industrial Average futures advanced 0.6%, suggesting investors were focusing on the potential economic benefits of easing geopolitical tensions.

European markets showed mixed results in early trading. Germany’s DAX index posted modest gains, while France’s CAC 40 edged slightly lower. Britain’s FTSE 100 declined as investors assessed both global economic developments and the outlook for interest rates.

In Asia, Japan’s Nikkei 225 extended its remarkable rally, rising 1.7% to a new record close above 71,000. The index has benefited from strong demand for technology-related shares and growing enthusiasm surrounding artificial intelligence investments. Investors also welcomed expectations that lower energy costs could support Japan’s economic recovery and improve corporate profitability.

South Korea’s Kospi index also reached a historic high, advancing 2.3%. The market continued to draw support from major semiconductor manufacturers, with Samsung Electronics and SK Hynix posting strong gains. Demand for advanced chips used in artificial intelligence systems has fueled investor interest in technology companies across the region and helped drive South Korean stocks sharply higher over the past year.

Taiwan’s stock market also moved higher, supported by optimism surrounding the global technology sector and continued demand for semiconductor products.

Not all Asian markets participated in the rally. Hong Kong’s Hang Seng Index fell more than 2%, while mainland China’s Shanghai Composite Index recorded a modest decline. Investors remain concerned about the pace of China’s economic recovery, ongoing property sector challenges, and uncertainty surrounding future policy support measures.

Australia’s benchmark index also slipped as traders weighed the impact of global interest rate expectations and commodity market fluctuations.

The previous session on Wall Street was dominated by concerns over the Federal Reserve’s outlook. The S&P 500 fell 1.2%, while the Dow Jones Industrial Average lost 1%. The technology-heavy Nasdaq Composite dropped 1.3%, pressured by declines among several major technology companies.

Federal Reserve Chair Kevin Warsh, speaking after the central bank’s policy meeting, offered few clues regarding the future direction of interest rates. He indicated that policymakers remain focused on bringing inflation under control and suggested that the central bank may revise the way it communicates policy decisions to investors, businesses, and households. Market participants interpreted the comments as a sign that borrowing costs could remain higher for longer than previously anticipated.

Several large technology companies contributed to the market’s decline. Microsoft, Amazon, and Nvidia all recorded losses, weighing heavily on major indexes. Meanwhile, SpaceX shares fell nearly 5%, marking their first decline since the company’s highly anticipated stock market debut last week.

Economic data released during the session provided some encouragement, showing stronger-than-expected retail revenue growth in May. The figures suggested consumer spending remains resilient despite elevated borrowing costs and ongoing concerns about inflation.

Energy markets continued to react to developments surrounding the U.S.-Iran agreement. Oil prices fell as traders anticipated increased crude supplies from Iran and the reopening of key shipping routes. The Strait of Hormuz, one of the world’s most important energy transit corridors, is expected to see increased tanker traffic as restrictions ease and regional security improves.

Brent crude, the international benchmark, dropped nearly 2% to around $78 per barrel, while U.S. benchmark crude fell more than 2% to approximately $74 per barrel. Although prices remain above levels seen before the conflict began, they have retreated significantly from the triple-digit levels reached during the height of tensions.

Currency markets were relatively stable. The U.S. dollar traded near 160.6 Japanese yen, while the euro edged higher against the dollar. Investors continued to monitor both central bank policy developments and geopolitical events for clues about future market direction.

As global markets digest the implications of the U.S.-Iran agreement, investors will remain focused on upcoming economic data, progress in nuclear negotiations, and signals from central banks. The combination of easing geopolitical risks, fluctuating energy prices, and uncertainty over interest rates is expected to remain a key driver of market performance in the weeks ahead.
