U.S. stock markets posted modest gains today, March 18, 2025, as investors navigated a mix of economic signals, ongoing trade policy uncertainty, and anticipation for the Federal Reserve’s next moves. The S&P 500 rose approximately 0.6% by midday, building on yesterday’s 36-point climb, while the Dow Jones Industrial Average ticked up nearly 1%, buoyed by strength in industrial and energy sectors. The Nasdaq Composite saw more muted gains, hovering near flat as tech stocks faced selective profit-taking after a volatile stretch.
The backdrop remains choppy. President Donald Trump’s tariff threats—set to escalate April 2—continue to rattle sentiment, though Ontario Premier Doug Ford’s suspension of a 25% electricity export surcharge has eased some cross-border tension. Meanwhile, Nvidia’s GTC conference, kicking off this week, has investors buzzing about AI-driven growth, with CEO Jensen Huang’s keynote today expected to spotlight new products like the Vera Rubin GPU.
Volatility lingers as a key theme. The VIX, Wall Street’s “fear gauge,” eased slightly but remains elevated, signaling unease ahead of the Fed’s rate decision. Economists suggest the Bank of Canada’s recent inflation jump to 2.6% in February could ripple into U.S. policy thinking, though focus here remains on domestic data and trade.
