Last week was rough for oil. Really rough. WTI crude fell 13.42% in five sessions, marking its worst week since the COVID lockdowns sent markets into a tailspin in March 2020. For a minute there, it looked like traders had decided the U.S.-Iran conflict was winding down, ceasefire hopes were real, and the Strait of Hormuz — that crucial chokepoint for global oil shipments — might reopen. The market seemed to be pricing in peace.
But here's the thing about oil crashes: they often set the stage for monster comebacks. And as it turns out, the ceasefire trade lasted about as long as a cheap umbrella in a storm. By Sunday evening, everything changed.
The Blockade That Changed the Game
President Donald Trump announced that the U.S. Navy would start blockading all maritime traffic in and out of Iranian ports, effective April 13 at 10 a.m. ET. This came after U.S.-Iran talks in Islamabad collapsed, with Tehran refusing to give up its nuclear enrichment program — Washington's non-negotiable demand.
So much for that ceasefire optimism. WTI crude, which you can track through the United States Oil Fund (USO), jumped 8.3% to $104.58 a barrel at Monday's open, pushing back above $100 for the first time since Tuesday. Brent crude, tracked by the United States Brent Oil Fund (BNO), rose 6.9% to $101.82. The blockade trade is here, and it might stick around for months.
What History Says About 13% Weekly Oil Crashes
Let's talk numbers. A TradingView Event Study looked at WTI weekly performance all the way back to 1986, searching for every instance where crude dropped more than 13% in a single week — the kind of move that signals a real structural shock, not just everyday market noise. It found 22 episodes over those 40 years.
The dates read like a highlight reel of oil market stress: the 1986 Saudi price war, the Gulf War, the 1998 Asia crisis, post-9/11, the 2008 financial collapse, the Arab Spring, the shale oversupply bear market, COVID-19 demand destruction, and now April 2026.
Here's the interesting part: in roughly three out of four of those episodes, crude was higher one year after the crash than at the moment of maximum weekly decline. That's a 77.3% win rate. The average gain over the next 12 months was 48.4%. Even if you strip out the biggest outliers, the median gain is still a solid 36.2%.
Short term, the data is more cautious. The average one-month gain is just 1.6%, because the market often retests lows before really recovering. So patience tends to pay off better than immediacy.
If history repeats and average forward returns hold, crude could climb to around $150 within the next 12 months. That's not a prediction — it's just what the math suggests based on past behavior.

So, what does this all mean? Oil just had a historically bad week, but history suggests that might be the setup for a significant rebound. Add in a fresh geopolitical spark like the Hormuz blockade, and you've got a recipe for volatility — and potentially, opportunity. Just remember: in oil markets, patience often pays better than panic.
