US stocks advanced on Monday as investors welcomed signs that the United States and Iran would pull back from the brink after exchanging fire near the Strait of Hormuz over the weekend, easing fears of a broader Middle East war that had hung over markets for weeks. The S&P 500 rose about 0.8%, the Dow Jones Industrial Average added roughly 0.4%, and the technology-heavy Nasdaq Composite climbed around 1.3%.
The gains followed reports, citing US officials, that both sides would 'stand down for now' and that technical talks to advance an interim agreement reached earlier in the month remained 'on track.' The de-escalation reversed some of the anxiety that had built up after the weekend strikes, which had threatened to derail the diplomatic process.
Oil prices, the most sensitive barometer of the conflict, stayed contained. West Texas Intermediate crude traded near $69.82 a barrel, up modestly on the day but well below the levels that a serious disruption to Hormuz shipping would imply, while Brent crude hovered around $72.39. The Strait carries roughly a fifth of global oil supply, and the prospect of Iran restricting traffic there had been the central worry for energy traders.
Adding to the conciliatory tone, Iran's president said Monday that the country was set to receive $6 billion in frozen assets held in Qatar, describing the release as part of the memorandum of understanding underpinning the US-Iran framework. The funds had been a sticking point, and their release was read by markets as a sign that the broader deal remained intact despite the weekend's violence.
The relief rally extended beyond the headline indexes, with risk appetite returning across sectors after a stretch of choppy, headline-driven trading in June. The S&P 500 had drifted lower in the final full week of the month as conflict fears and questions over the path of interest rates weighed on sentiment; Monday's bounce recovered a chunk of that ground.
Still, analysts cautioned that the calm rests on a fragile foundation. The ceasefire has already been strained once, and the same diplomatic process that buoyed markets on Monday could just as easily unsettle them if talks stall or fighting resumes. With oil holding below $70 and equities recovering, investors are betting the standoff stays contained — a bet that depends on a deal both Washington and Tehran have tested in recent days.
