Having begun over four months ago, the U.S.-Iran conflict continues to draw the attention of investors and traders around the world while influencing global markets and industries. Following the exchange of strikes on Tuesday night, the U.S. president stated that the memorandum of understanding - signed by the two parties last month to end the conflict - was no longer in effect. Speaking at the NATO summit in Turkey, Trump said he no longer wanted to engage with Tehran. Although he allowed negotiators to continue the ongoing talks, he expressed little confidence that they would produce meaningful results.

In addition, the U.S. reimposed previously lifted sanctions on Iranian oil sales in response to attacks on tankers in the Strait of Hormuz, though Iran hasn’t explicitly claimed responsibility.

The announcement that the ceasefire was over triggered a surge in oil prices, after they had already approached prewar levels. Brent crude climbed to a two-week high. 

Meanwhile, the U.S. dollar strengthened on safe-haven demand, reaching its highest level in nearly a week, while investors also eyed the upcoming release of the June 17–18 FOMC meeting minutes - the first chaired by Warsh. The EUR USD exchange rate hovered near $1.14, close to its weakest level in nearly a year. The USD JPY rate advanced for a fourth consecutive session, climbing to its highest level since July 2. Rising oil prices reignited inflation concerns, putting pressure on Japan, which relies heavily on Middle Eastern oil imports, and weighing on the yen. As a result, markets remain alert to the possibility of an intervention. Japan's Finance Minister recently reiterated that the authorities stand ready to step in if necessary.

Moreover, surging oil prices also weighed on equities, leading to broad declines in U.S. stocks. The Dow Jones Industrial Average fell below 53,000, while the S&P 500 and Nasdaq 100 declined 0.6% and 0.4% respectively.

As a result, markets now await the next move. Trump's remarks could ultimately mark either a complete breakdown of diplomatic efforts or merely a temporary pause in negotiations. Either outcome will have implications not only for the economies of the two countries but also for broader financial markets. For oil markets, however, even if prices retreat in the near term, the underlying situation is unlikely to change significantly. The U.S.-Iran crisis has already disrupted global energy supply flows and contributed to a severe inventory shortage.
