ISTANBUL, June 15, 2026 — Global financial markets moved higher on Monday after reports that the United States and Iran had reached an agreement, easing concerns over geopolitical tensions and energy supply disruptions. The development boosted investor confidence worldwide and supported gains across Turkish financial markets.
According to reports, Pakistan’s Prime Minister announced that Washington and Tehran had reached a deal, while U.S. President Donald Trump said a peace agreement had been completed and that restrictions affecting the Strait of Hormuz would be lifted. Iranian Deputy Foreign Minister Kazem Gharibabadi also confirmed that an agreement had been reached, with a memorandum expected to be signed in Switzerland on June 19.
The prospect of reduced geopolitical risk encouraged investors to increase exposure to risk assets. Analysts said the agreement could ease inflationary pressures by lowering energy market uncertainty and may reduce the need for prolonged high interest rates globally. The development comes as several major central banks prepare to announce monetary policy decisions this week.
In Turkey, the benchmark BIST 100 index climbed 3.1% during the first half of trading, reaching 14,370.35 points. Banking stocks led the rally, with the sector index rising more than 5%, while holding companies also posted strong gains.
The precious metals market also advanced. On Borsa Istanbul’s Precious Metals and Diamond Market, the price of standard gold increased 4.3% to close at TRY 6.55 million per kilogram, compared with TRY 6.28 million at the previous close. Total gold trading volume exceeded TRY 11 billion.
Currency markets showed limited movement. In Istanbul’s free market, the U.S. dollar traded at approximately TRY 46.28, while the euro changed hands near TRY 53.81.
Market participants continue to monitor economic data from the United States, including industrial production, capacity utilization, and the New York Federal Reserve’s manufacturing index, for further indications of the global economic outlook.
Background: Markets had been closely watching U.S.-Iran negotiations for weeks, with investors viewing any breakthrough as potentially positive for global trade, energy supplies, and inflation trends. Recent optimism surrounding a possible agreement had already contributed to improved market sentiment before Monday’s reported breakthrough.
