Wall Street indices posted modest gains on Tuesday as cooling inflation data boosted investor sentiment, even as a historic collapse in IBM shares rattled the technology sector. The S&P 500 rose 0.38%, the Nasdaq Composite climbed 0.9%, and the Dow Jones Industrial Average added 0.02%. Simultaneously, geopolitical instability in the Middle East drove oil prices up by approximately 3%.
Market Response to Easing Inflation
Inflation figures for June dropped to 3.5%, a significant cooling from the 4.2% rate recorded the previous month, according to official data. Core inflation settled at 2.6%. This deceleration is being closely monitored by the Federal Reserve, which has maintained interest rates between 3.5% and 3.75%.
Kevin Warsh, the new Fed-sjef, addressed the finance committee in Congress on Tuesday, signaling a firm stance against persistent price increases. “If we succeed in conducting the right monetary policy, and we will, the inflation peak of the last five years will belong to the past,” Warsh stated during the hearing.

IBM Records Worst Single-Day Performance
International Business Machines (IBM) suffered its most severe stock market decline in history, with shares closing down 25.2% on Tuesday. The sell-off surpassed the company’s previous record drop of 23.7% in 1987.

The decline followed a weak quarterly report. IBM reported preliminary second-quarter revenue of 12.7 billion dollars, falling well short of analyst expectations of 17.9 billion dollars. Arvind Krishna attributed the shortfall to supply chain disruptions and a shortage of memory chips, which he noted were exacerbated by the current artificial intelligence boom.
“The development turned out worse than we had expected,” Krishna wrote in a letter to investors, noting that the company’s Z-series mainframes and related software also contributed to the revenue miss. The weakness in IBM’s performance spilled over to other tech-related firms, with Workday Inc. falling 3.49% and ServiceNow dropping 5.79%.
Geopolitical Volatility and Oil Prices
Brent spot oil prices climbed to approximately $85 per barrel by Tuesday evening, marking a 3% increase since midnight. Prices have remained volatile as conflict in the Middle East intensifies.
The upward pressure on oil follows reports of ongoing military activity, including U.S. strikes against Iran for three consecutive days. These actions occurred in response to alleged Iranian attacks on commercial vessels and U.S. bases in neighboring countries. Before the escalation in late February, around 20 percent of the world’s oil was transported through the Strait of Hormuz, underscoring the market’s sensitivity to regional instability.
Pro Tip:
When tech bellwethers like IBM miss earnings targets, investors often look to the broader software and infrastructure sector to determine if the issue is company-specific or systemic.
