Remarks by U.S. President Donald Trump about Iran and a decline in vessel traffic through the Strait of Hormuz increased concerns about energy supplies in global markets. Nvidia’s plan to mobilize more than $500 billion in financing for artificial intelligence infrastructure, however, partly limited the negative mood in the markets.
Trump’s Iran remarks raise risk concerns
Donald Trump said the possibility of a major attack against Iran remained if an agreement could not be reached with the country. Trump said Iran was demanding war reparations in exchange for signing an agreement and argued that Tehran was the party that should make the payment.
The remarks reinforced expectations that reaching an agreement with Iran could take longer. Iran’s demand that the Strait of Hormuz remain closed also kept concerns about energy supplies alive.
Brent crude rises to $87.70
Driven by supply concerns, October-dated Brent crude rose 5% to $87.70 a barrel. Brent later traded sideways at around $87.80.
The rise in oil prices brought global inflation risks back into focus, while the yield on the U.S. 10-year Treasury note rose by about 6 basis points to 4.71%. Expectations for a hawkish stance from the Federal Reserve also strengthened.
Analysts said weaker employment in the United States had shifted expectations for possible Fed moves to a less hawkish position than in the previous period. Pricing in money markets pointed to divided expectations over the Fed’s move next month, while the probability that the bank would end the year with one rate hike was assessed at 75%.
Cleveland Fed President Beth Hammack said multiple rate hikes might be needed to bring inflation down. The U.S. inflation data due to be released could change expectations for the Fed, and market volatility could increase both before and after the data.

Nvidia targets more than $500 billion in capital
Investment activity in the artificial intelligence sector partly offset pressure stemming from the Middle East. U.S.-based technology company Nvidia announced that it had formed a strategic partnership with six financial institutions to mobilize more than $500 billion in third-party capital for the development of AI infrastructure.
The company signed memorandums of understanding with Apollo, Blackstone, BlackRock, Brookfield, Goldman Sachs and KKR to establish independent computing finance platforms.
Nvidia Founder and Chief Executive Officer Jensen Huang said the company’s operations, which began with chip production, were expanding toward the creation of a new, investable infrastructure class known as AI factories.
BlackRock Chief Executive Officer Larry Fink said unprecedented levels of investment and a skilled workforce were needed to build AI infrastructure. Goldman Sachs Chief Executive Officer David Solomon viewed positively the possibility of creating a new credit market based on Nvidia computing.
Analysts said the agreement could make it easier to secure financing for AI infrastructure investments in the coming period. However, increased cyclicality in the sector could amplify the impact of potential negative developments.
Gold tests a peak at $4,435
The U.S. 10-year Treasury yield remained broadly flat amid concerns that higher energy prices could increase inflationary pressure. The dollar index held its position around 99.
Supported by uncertainty over the Fed’s future steps, gold rose 1.1% to $4,390 an ounce. The price later tested a roughly two-and-a-half-month high at $4,435; after retreating from that level, gold traded at $4,377 an ounce, down 0.3%.
