Wall Street indexes advance with boost from chips, US-Iran deal optimism

US stock indexes rallied on Thursday (Jun 18), with the Nasdaq’s 1.9 per cent advance boosted by gains in semiconductor shares, while inflation fears eased after the US and Iran signed a peace agreement, although investors still priced in interest rate hikes in 2026 from the US Federal Reserve.

The Philadelphia semiconductor index sharply outperformed the rest of the market with a 6.4 per cent rally as Intel’s shares jumped to a record high and finished up 10.6 per cent. US President Donald Trump said iPhone maker Apple had agreed to work with Intel to design and manufacture its chips in the US.

Early in the session, oil prices had slid to their lowest levels since early March after the US and Iran signed an interim agreement that extends the April ceasefire by another 60 days to allow the sides time to reach a final deal.

Inflation has been a huge worry for investors as oil prices had soared since the war began in late February. Although Trump threatened to resume attacks if Iran failed to honor its commitments, the first ships started sailing through the Strait of Hormuz, where transportation of oil, gas, fertiliser and other cargoes had been disrupted since the start of the war.

On Wednesday, all three of Wall Street’s major indexes tumbled, with investors pricing in the likelihood of Fed rate hikes after the central bank’s new chair Kevin Warsh underscored the need to curb inflation and other policymakers signalled higher borrowing costs ahead.

“Markets got spooked by Warsh yesterday essentially promising to contain inflation,” said Tony Welch, chief investment officer at SignatureFD, but he pointed to easing oil prices and recent strength in earnings and economic data. “All together, the package of data is still supportive whether or not the Fed has become a little bit more hawkish.”

Traders were betting on a roughly 50 per cent chance of a 25-basis-point rate hike as soon as September and a roughly 20 per cent probability for a 50-basis-point hike, according to CME Group’s FedWatch tool.

Investors were still assessing Warsh’s indication that the Fed would provide less guidance on future policy moves and his stated focus on price stability. Eric Johnston, chief equity and macro strategist at Cantor, said, “The conclusion today is that the Fed has more credibility around inflation.”

The Dow Jones Industrial Average rose 72.15 points, or 0.14 per cent, to 51,564.70, the S&P 500 gained 80.48 points, or 1.08 per cent, to 7,500.58 and the Nasdaq Composite gained 496.28 points, or 1.91 per cent, to 26,517.93.
