Iran War, 5% Yields, and Nasdaq at Records: Markets Don't Care

Let's do a quick vibe check. The US is fighting a war in Iran, the 10-year Treasury yield hit 5.01%, the Strait of Hormuz is partially closed, and Trump is at the UN General Assembly getting yelled at by CNN reporters. And the Nasdaq just closed at 27,122, up 2.26% on Monday, good for a fresh record high. Totally normal stuff.

The S&P 500 finished at 7,764.70, up 1.49% on Monday after two down days to open the week. The VIX sits at 14.87, which is the market's way of saying 'war? what war?' Historically, a VIX below 15 signals investors are about as stressed as someone on their third vacation margarita. Mohamed El-Erian flagged this disconnect in a recent CNBC appearance, warning that inflation is primarily a supply-side problem and that central banks are being pushed center stage as the only game in town, even though rate hikes are the wrong tool for the job. He also noted the 10-year has not seen the relief you would normally expect, partly because hyperscaler bond issuance is crowding out demand. When El-Erian is bearish on the bond market and bulls are still buying tech, someone is going to be wrong.

So what is actually driving the rally? Three things are doing most of the heavy lifting. First, Meta's Muse AI lit a fire under the Nasdaq after the stock surged roughly 11% in one of its best non-earnings days ever. JP Morgan called Muse a potential candidate for the most widely used consumer AI app since ChatGPT. Second, Alibaba unveiled a new AI chip claiming three times the performance of its previous generation, rattling Nvidia's cage and pulling the whole AI infrastructure trade higher. Third, Iran signaled it is ready to reopen the Strait of Hormuz within seven days if the US eases military pressure, which bled geopolitical premium out of oil and gave bond traders a brief moment of calm before yields snapped back to 5.01%.

The bull case is pretty straightforward: AI spending is accelerating, a Bloomberg strategist cited a Goldman Sachs projection of $7.5 trillion in AI infrastructure investment, and roughly 30% of S&P 500 companies raised guidance last quarter. The bear case is that the average stock is still down 20% from its highs despite index strength, multiple compression is real, and the Fed is expected to hike once more in October with rate cuts nowhere in sight for 2026 or 2027. That is a recipe for a narrow, index-distorting rally where the Magnificent Few drag everyone else along.

The Trump-Xi summit later this week is the real wildcard. The Iran war headlines are loud, but analysts described the summit as the more significant geopolitical event, with Chinese purchases of Iranian oil (roughly 90% of Iran's output goes to China) and trade tensions both on the table. Trump has historically been deferential to Xi, which means the US sanctions pressure on Iran may have a very large hole in it.

Markets are pricing in a diplomatic soft landing on Iran and a Fed that threads the needle. That is a lot of optimism to pack into a VIX of 14, but then again, the market has been wrong for longer than most short sellers can stay solvent.
