# Stock markets rise as oil prices plunge ahead of Fed meeting Hormuz Strait negotiations and Fed decision stir markets. - **Source:** [Fortune](https://fortune.com) - **Published:** 2026-07-27 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/bfd605d2-0f6d-4e5b-94c2-49ebf0d1e862 ## Market rally Easing tensions between the U.S. and Iran, along with the potential reopening of the Strait of Hormuz, created a positive atmosphere in global markets. Dow Jones, S&P 500, and Nasdaq futures saw significant gains. South Korea's Kospi index also rose by 1.1%. ## Sharp drop in oil prices Positive progress in Hormuz Strait negotiations pushed oil prices lower. U.S. crude fell 5.44% to $84.45 per barrel, while Brent crude dropped 5.25% to $91.70. This could provide the Fed with some breathing room in its inflation fight. ## Fed meeting expectations Wall Street is closely watching this week's Fed meeting. A debate is expected between raising interest rates or keeping them steady to combat inflation. The decision could also impact AI stocks, which have recently weakened. ## Tech giants' earnings reports Earnings reports from Microsoft and Meta on Wednesday, followed by Apple and Amazon on Thursday, could create market volatility. Alphabet surpassed expectations last week but reported negative cash flow due to high spending. ## Developments in the semiconductor sector Chip giants like SK Hynix and Samsung signed new deals to expand in the AI infrastructure market. SK Hynix will supply semiconductors to AI developer Anthropic, while Samsung secured a $200 billion chip manufacturing deal with Broadcom. ## Impact of geopolitical tensions on markets Alongside U.S.-Iran negotiations, Ukraine's attack on an Iranian support ship in the Caspian Sea has heightened regional tensions. These developments could lead to fluctuations in oil markets and shifts in investor risk perception. ## Sources covering this story - https://fortune.com/2026/07/26/kospi-index-dow-futures-us-stocks-hormuz-talks-oil-prices-iran-war-fed-meeting/ — --- _Summary written by Brifing from the original reporting.
