TradingKey’s The Week on Wall Street: Iran Truce Cools Inflation, Fed Hawks Rate, but U.S. Stocks Still End Week Higher

TradingKey - The geopolitical ceasefire between the United States and Iran on Monday, June 15, marked a major breakthrough, reopening the Strait of Hormuz and sending Brent crude down 4.8 percent to around 83 dollars per barrel, which significantly eased global inflation anxieties. Domestically, May retail sales surged by a better-than-expected 0.9 percent month-over-month, with the core control group rising 0.7 percent, demonstrating resilient consumer spending. Meanwhile, May industrial production edged up 0.1 percent, showing steady domestic manufacturing improvement supported by tariffs and energy sector activity, despite falling slightly short of consensus estimates.

In a holiday-shortened trading week ending Thursday, June 18, before the Juneteenth National Independence Day holiday on Friday, June 19, major U.S. stock indexes posted solid weekly gains. The S&P 500 rose 0.9 percent over the period to close at 7,500.58, marking its eleventh positive week in twelve, while the Nasdaq Composite jumped 2.4 percent to end at 26,517.93, driven by a late-week technology resurgence. The Dow Jones Industrial Average finished in positive territory, closing at 51,564.70 after a minor gain of 0.14 percent on Thursday. Semiconductor stocks experienced high volatility, undergoing a sharp pullback on Wednesday following hawkish monetary signals, but rebounded strongly on Thursday as the iShares Semiconductor ETF jumped over 6 percent, led by a 10.6 percent surge in Intel and a 3 percent rise in Nvidia.

The Federal Open Market Committee meeting on June 17 was the week's focal event, marking Kevin Warsh's debut as Federal Reserve Chair. While the Fed unanimously held the policy rate target range steady at 3.50 percent to 3.75 percent, the updated Summary of Economic Projections delivered a hawkish shift. The median dot plot projected a rate hike by year-end 2026, targeting 3.75 percent, a complete reversal from the rate cuts projected in March. Chair Warsh demonstrated a distinct shift in communications, drastically shortening the official policy statement to just 132 words, stripping away previous forward guidance on rate cuts, and explicitly stating the Committee’s absolute commitment to price stability.

Market sentiment oscillated between geopolitical relief and monetary caution. Risk appetite surged early on the Middle East ceasefire and falling oil prices, but briefly soured on Wednesday as investors digested the Fed's hawkish rate projections. However, sentiment rebounded sharply on Thursday, catalyzed by the Trump administration's announcement of a partnership between Intel and Apple to manufacture chips domestically, which triggered substantial inflows into technology and semiconductor equities. Meanwhile, Treasury yields saw modest upward pressure as fixed-income markets adjusted to a higher-for-longer rate horizon, while post-IPO profit-taking saw recently listed SpaceX trim recent gains.

Overall, the U.S. equity market is operating under a logic of resilient growth colliding with restrictive monetary policy. The underlying economic cycle remains robust, characterized by a healthy labor market, steady manufacturing activity, and strong consumer demand, which effectively mitigates immediate stagflation risks. Although the Federal Reserve's hawkish stance acts as a valuation headwind, the cooling of energy-driven inflation from the geopolitical truce is expected to eventually alleviate price pressures. In the interim, strong corporate fundamentals and targeted policy support in high-tech manufacturing are offsetting restrictive rate dynamics, keeping the broader upward trend intact.
