Oil prices tumble again on US-Iran deal; S&P 500 falls

Market Reactions to US-Iran Deal and Global Financial Movements

By Caroline Valetkevitch and Amanda Cooper

Oil Prices Plunge on Hopes of Middle East Peace

NEW YORK/LONDON, June 16 (Reuters) - Oil prices fell more than 5% on Tuesday, extending this week's losses on hopes a U.S.-Iran deal to end the Middle East war will allow oil to flow through the Strait of Hormuz, while technology shares weighed on the S&P 500 and Nasdaq.

Details of the US-Iran Interim Deal

Details began to emerge of the U.S. and Iran's interim deal, with U.S. President Donald Trump saying it will rule out a nuclear weapon for Tehran and a U.S. official saying it allows Iran to sell oil upon signing.

Oil Market Performance

Brent crude futures fell $4.21, or 5.1%, to settle at $78.96 a barrel, while U.S. West Texas Intermediate (WTI) crude fell $4.70, or 5.8%, to $76.05.

Technology Stocks and Major Market Movers

SpaceX Surges Past Tech Giants

SpaceX roared past Amazon's market valuation and briefly topped that of Microsoft, rapidly scaling the list of the world's most valuable companies on a topsy-turvy trading day fueled by frenzied action in the firm's newly listed options contracts. SpaceX, which started trading on the Nasdaq on Friday, was up 4.8% on the day.

Analyst Insights on Tech Sector Momentum

"It's still really all about the exuberance of SpaceX and what SpaceX can pull along with it as far as the Nasdaq," said Bruce Zaro, managing director at Granite Wealth Management in Plymouth, Massachusetts.      Tech shares could struggle to keep the momentum going, with second-quarter U.S. earnings still weeks away, he said. 

Nvidia's Bond Market Move

Nvidia, the world's most valuable maker of AI chips, surprised investors by tapping the bond markets for $25 billion. The company said the cash would be used for general corporate purposes and the debt sale was to establish a liquid benchmark for future issuance. Nvidia shares dropped 2.4%.

Federal Reserve and Central Bank Updates

Fed Policy Outlook

Investors were also cautious ahead of the Federal Reserve's policy update due on Wednesday afternoon, with some concerned new Fed Chair Kevin Warsh could strike a more hawkish tone at his first meeting.

Interest Rate Expectations

The Fed is widely expected to hold rates steady at 3.50% to 3.75% and could drop its easing bias from the policy statement.
