Market Flash: Iran War Fears Has Investors Pressing Sell Button

1) Markets Reprice “Geopolitics” in Real Time

U.S. equities sold off hard this morning as the Iran conflict escalated and shipping risk in the Strait of Hormuz jumped from “headline noise” to “macro variable.” The S&P 500 slid ~2% on March 3, volatility popped, and the market’s reflex was classic: sell cyclicals/growth, buy energy exposure. Ask airlines how that’s going.

Oil did the heavy lifting. Brent spiked roughly 7% on the day (after big weekend moves) as markets priced actual disruption risk — tankers rerouting, insurance getting yanked, and escalating strikes tied to Gulf energy infrastructure. Supply constraints make all the oil bulls go “Moooo.”

2) Inflation’s Uninvited Plus-One: Oil Moves the Cut Timeline

The bigger issue wasn’t just “stocks down.” It was “stocks down and inflation risk up.” Treasuries sold off as energy prices shoved inflation expectations higher — pushing yields up and making the usual “risk-off = bonds rally” trade look less reliable.

Rate-cut expectations got nudged out again. Markets started leaning further away from near-term easing as the oil shock complicates the Fed’s “inflation gliding path” narrative, especially with multiple Fed voices signaling caution about declaring victory.

3) The “Prices Paid” Problem: Manufacturing Expanded… and So Did Cost Pressure

Away from the fireworks, the data tape had an awkward undertone: U.S. manufacturing stayed in expansion territory for a second straight month — but input prices surged. ISM’s Prices Index jumped to its hottest reading since mid-2022, a reminder that inflation can reappear through the side door even when growth looks “fine.” Layer that on top of an energy shock and you get the market’s current mood: growth is holding up, but the margin for policy comfort is shrinking.

4) Credit Clears Its Throat: Private Credit Gets a Stress Test

One under-the-radar “tell” this week: liquidity sensitivity in private credit. Blackstone’s flagship private credit fund saw elevated withdrawal requests (and Blackstone increased its usual withdrawal cap to meet them). That doesn’t mean “doom”— it means investors are paying attention to liquidity terms, valuations, and what happens when risk premia wake up.
