Deep Look: Stocks Rise and Oil Prices Ease as Iran War Drives Volatility
NEW YORK — U.S. stocks climbed Wednesday as investors reacted to renewed hopes that the ongoing conflict involving Iran could ease, while oil prices declined amid expectations that energy supply disruptions might lessen. Despite the gains, markets remained volatile, reflecting continued uncertainty about the duration and escalation of the conflict.
The S&P 500 rose 0.8% during morning trading, continuing a pattern of sharp swings since the war began more than three weeks ago. The Dow Jones Industrial Average climbed 323 points, or 0.7%, while the Nasdaq composite advanced 1.3%.
However, early gains proved unstable. The S&P 500 initially surged as much as 1.2% before quickly trimming those gains within the first half hour of trading. The rapid shifts reflect the broader volatility gripping global markets as investors respond to evolving geopolitical developments.
War Uncertainty Keeps Markets on Edge
Financial markets have experienced dramatic swings since strikes by the United States and Israel on Iran triggered the conflict. Investor sentiment has shifted repeatedly, sometimes within hours, depending on developments in diplomacy or military escalation.
Adding to uncertainty Wednesday, Iranian state media reported that Tehran rejected a 15-point U.S. ceasefire proposal. Iran also launched new attacks across the Middle East, including a strike that caused a major fire at Kuwait International Airport. Meanwhile, the United States announced plans to deploy additional paratroopers and Marines to the region.
Despite those developments, optimism remained evident across global markets.
Stock indexes rose more than 1% in major international markets, including London, Paris, and Shanghai. Japan’s Nikkei 225 index jumped 2.9%, reflecting global investor confidence that tensions could eventually cool.
Oil Prices Fall as Supply Hopes Grow
Oil prices dropped sharply, helping lift equities and ease inflation concerns. Brent crude fell 4.3%, slipping below $96 per barrel after previously nearing $120 during the conflict.
The drop came as investors anticipated that a potential easing of hostilities could allow oil shipments to resume through the Strait of Hormuz, a crucial shipping route near Iran’s coast. Many tankers have been stalled outside the region, contributing to earlier price spikes.
Lower oil prices often provide relief for companies with high fuel costs, and travel-related stocks responded positively.
Norwegian Cruise Line Holdings rose 3.8%, while United Airlines gained 3.5% as fuel cost concerns eased.
Treasury Yields Decline
Bond markets also reflected improving sentiment. The yield on the 10-year Treasury note fell to 4.33% from 4.39% the previous day. Lower Treasury yields can help reduce borrowing costs for consumers and businesses.
Even with the decline, yields remain higher than before the conflict began, when the 10-year Treasury yield stood at 3.97%.
Higher borrowing costs tied to rising yields have been a concern for investors, particularly if elevated oil prices fuel inflation and delay potential Federal Reserve interest-rate cuts.
Gold Rebounds
Gold prices rose 3.5% to approximately $4,556 per ounce. The rebound followed earlier declines triggered by rising Treasury yields.
Gold typically performs well during geopolitical uncertainty but can struggle when bond yields rise, since gold does not provide interest income.
Earlier this month, gold briefly approached $5,400 per ounce before retreating as yields climbed.
Individual Stock Movers
Several companies posted notable moves:
- Arm Holdings surged 15.2% after unveiling new AI-focused data center chips
- Robinhood Markets jumped 7.3% after announcing a $1.5 billion stock buyback
- Terns Pharmaceuticals rose 5.4% following Merck’s $6.7 billion acquisition deal
- Merck gained 2.1% following the announcement
On the downside:
- On Holding fell 6.8% after CEO Martin Hoffmann stepped down
- Pop Mart International tumbled 22.5% after earnings failed to meet expectations
Global Markets Reflect Cautious Optimism
Markets worldwide showed cautious optimism as investors balanced diplomatic hopes against military escalation risks. Analysts warn volatility could continue as developments unfold.
With oil prices, interest rates, and geopolitical risks all shifting rapidly, investors remain focused on any signs of progress toward ending the conflict.
For now, markets continue to “yo-yo” — rising on hope and falling on uncertainty — as the Iran conflict remains a central driver of global financial sentiment.
