Global financial markets edged lower on Friday as investors weighed growing uncertainty surrounding efforts to secure a lasting peace agreement between the United States and Iran.

The cancellation of high-level negotiations between American and Iranian officials dampened market sentiment, while the Japanese yen hovered near its weakest level in almost 40 years, increasing speculation that Tokyo may be forced to intervene in currency markets.

Investors entered the day cautiously after U.S. Vice President JD Vance withdrew from planned peace talks with Iranian negotiators in Switzerland. The move raised fresh doubts about the durability of recent diplomatic progress that had briefly eased fears of a broader conflict in the Middle East.

The setback in negotiations came at a sensitive moment for global markets, which have been closely tracking developments in the region. Although tensions have eased somewhat following a ceasefire agreement between Israel and Hezbollah in Lebanon, traders remain uncertain about whether recent diplomatic breakthroughs can evolve into a comprehensive and lasting peace settlement.

As a result, global equities slipped. The MSCI All-World Index moved lower, while European stock markets surrendered earlier gains. U.S. stock futures also declined modestly, reflecting investor caution despite the closure of American financial markets for the Juneteenth holiday.

Energy markets remained a central focus. Oil prices slipped below the $80-per-barrel mark after news emerged that Israel and Hezbollah had agreed to a ceasefire, reducing immediate concerns about disruptions to regional energy supplies. The decline in crude prices was also supported by the reopening of key shipping routes through the Strait of Hormuz, one of the world’s most important energy corridors.

The waterway had been effectively closed during the recent conflict after the United States imposed a blockade on Iran. Following the lifting of that blockade, commercial tankers have begun moving through the strait once again, offering hope that global oil supplies can normalize.

However, analysts warned that a full recovery in shipping activity may take considerable time. While the reopening of Hormuz is a positive development, shipping companies and insurers remain cautious due to ongoing geopolitical risks. Some market observers believe traffic levels could remain significantly below pre-conflict levels even if the current agreements hold.

Meanwhile, currency markets continued to be dominated by the strength of the U.S. dollar. The greenback climbed toward its strongest weekly performance in a month, supported by expectations that the Federal Reserve could raise interest rates later this year.

Confidence in the dollar has been reinforced by Federal Reserve Chair Kevin Warsh’s commitment to combating inflation and maintaining price stability. Investors have rapidly adjusted their expectations, with traders now assigning a much higher probability to at least one U.S. rate increase before the end of the year.

The changing outlook for monetary policy has also affected bond markets. Short-term Treasury yields have risen sharply as investors price in the possibility of tighter policy, while longer-dated yields have remained relatively stable amid expectations that lower energy prices could help contain inflation over the longer term.

The strongest impact of the dollar’s rise has been felt in Japan. The yen weakened to around 161 per dollar, leaving it close to levels not seen since 1986. The currency has now declined in five of the last six weeks, prompting repeated warnings from Japanese officials that intervention remains a possible option if market movements become excessively volatile.

Currency traders are paying close attention to the 160-per-dollar threshold, which many analysts view as a level that could trigger official action from Tokyo. Japanese authorities have repeatedly stressed that they are monitoring foreign exchange markets closely and stand ready to respond if necessary.

In the United Kingdom, the pound recovered slightly after suffering a sharp decline following the Bank of England’s decision to leave interest rates unchanged. The central bank voted 7-2 in favor of maintaining its current policy stance, signaling continued caution as policymakers assess inflation and economic growth prospects.

Political developments also attracted attention in Britain. Labour politician Andy Burnham secured a parliamentary election victory in northern England, a result that strengthens his position within the party and removes a major obstacle to a potential leadership challenge against Prime Minister Keir Starmer. Reports suggested that several senior cabinet members may soon press Starmer to outline a timetable for his departure, adding another layer of political uncertainty to the UK’s economic outlook.

As investors look ahead, attention remains firmly focused on the Middle East, where the success or failure of ongoing diplomatic efforts could shape market sentiment in the weeks ahead. While falling oil prices and the reopening of key shipping routes have provided some relief, the suspension of U.S.-Iran talks serves as a reminder that geopolitical risks continue to cast a shadow over the global economy.

For now, traders are balancing optimism about easing regional tensions against concerns that the path toward lasting peace remains fragile, leaving markets vulnerable to sudden shifts in both politics and investor confidence.
