You know the drill. A geopolitical shock hits the market, oil jumps, and the immediate chorus from a certain corner of Wall Street is: "It's priced in," "It's contained," "Don't overreact." It's a well-documented instinct to downplay the surprise. Robin Brooks, a Senior Fellow at The Brookings Institution, isn't having it this time.
In a Substack post, Brooks called out analysts who were already minimizing Monday's oil price move in the wake of the U.S.-Iran conflict. "If you admit to being surprised, this means you didn't see something coming, which in markets means you failed," he wrote. "This is why so much market commentary tends to downplay shocks when they happen."
But Brooks says the numbers don't lie, and they tell a story of a shock that's being undersold. He put a direct comparison on it: Monday versus February 24, 2022—the day Russia invaded Ukraine. Brent crude surged over 7% on Monday. On invasion day in 2022, it rose just 2%. "Yesterday's spike in oil prices was more than three times as big," Brooks noted. "That's a big shock no matter how you cut it."
Why the bigger reaction? It's simple supply math. Russia exports around 7 million barrels of oil per day. The Strait of Hormuz—the narrow waterway now at the center of the U.S.-Iran tensions—sees a staggering 20 million barrels transit every single day. The potential choke point for global oil flows is just that much more significant.
The market's behavior on Monday backed up the "big shock" thesis, but in a different way than in 2022. Back then, the S&P 500 rallied 2% on invasion day. This Monday, it was flat. Gold rallied this time, whereas it fell initially in 2022. The dollar strengthened across the board. Brooks called it a classic risk-off session, with markets "trading Iran like it's a big shock—not a little one."
The commodity volatility didn't stop at Monday's close. According to data from Trading Economics, WTI crude pushed toward $81 a barrel on Tuesday, and coal jumped over 8%. Equity markets, meanwhile, turned lower. The S&P 500, tracked by the SPDR S&P 500 ETF Trust (SPY), was down 1.36%. The Nasdaq Composite, tracked by the Invesco QQQ Trust (QQQ), fell 1.42%.
The message from Brooks is clear: when the initial market move is three times the size of the Ukraine invasion shock, and it's centered on the world's most critical oil artery, maybe it's time to listen to what the price action is screaming, not the commentary trying to explain it away.
