(Sharecast News) - Major indices closed lower on Monday as optimism over a potential US‑Iran agreement to re-open the Strait of Hormuz faded.

At the close, the Dow Jones Industrial Average was down 0.11% at 53,975.98, while the S&P 500 shed 0.06% to 7,753.11 and the Nasdaq Composite saw out the session 0.32% weaker at 26,605.36.

The Dow closed 60.95 points lower on Monday, taking a bite out of gains recorded in the previous session after a much weaker-than-expected non-farm payrolls report made a September rate hike from the Federal Reserve appear unlikely.

However, investor sentiment weakened after Iran said that it was not engaged in any direct negotiations with Washington on restoring free passage through the key shipping corridor.

Iran's foreign minister Abbas Araghchi said there was "no possibility of restarting negotiations" with the US if it continued to violate the pair's June memorandum of understanding, without compensating for its "violations". Tehran did announce that it was closing in on a deal with Oman to re-open the Strait of Hormuz.

As a result, West Texas Intermedia crude rose 5.24% to $82.28 a barrel as traders reassessed the geopolitical backdrop, while international benchmark Brent crude moved 5.07% higher to $87.79 a barrel.

Hopes for a breakthrough had been lifted last week after Treasury Secretary Scott Bessent told CNBC a deal was close. However, Donald Trump later told Axios on Sunday that the US was "only semi‑negotiating" with Iran and intended to maintain economic pressure.

No major corporate earnings or data points were released on Monday.
