Believe it or not, John D. Rockefeller knew something that many oil investors still don’t know. His insight into crude profits wasn’t a secret, either.
Actually, it was pretty simple — you don’t get rich drilling for oil, the real fortune is in refining it!
While every other businessman in the 1870s was obsessed with finding crude deposits and extracting barrels from underground, Rockefeller understood something they completely missed.
The real profit wasn’t in production, it was in the spread… that gap between what you paid for a barrel of crude and what you could sell its products for.
And it was with this mantra in mind that Rockefeller built Standard Oil — by controlling refining capacity, not oil fields. 
When crude flooded the market and prices crashed, competing producers went bankrupt.
Yet, Rockefeller’s refineries still made money because they owned the margin. He could buy crude from desperate oil men at basement prices and sell gasoline and kerosene at premium rates.
You see, that spread was Rockefeller’s fortress, and it quickly turned him into the richest man in America.
Almost 150 years later, the exact same playbook is printing money again, except now the profits are just funneling into one man’s pocket.
Today’s oil war has created a setup that would make Rockefeller smile.
When the U.S.-Iran war broke out a few months ago, crude prices spiked from $65 to $112 per barrel in under a month.
Shipping routes turned chaotic (spoiler: they still are!), and refined product supply got constrained. Refinery capacity became a scarce resource, and the gap between what refiners pay for crude and what they sell gasoline and diesel for just exploded to historically elevated levels.
Naturally, there are a few players out there with access to cheap domestic crude, and they’re playing Rockefeller’s game right now.
And the best part for their shareholders is that they’re winning.

Meet the Profits Behind 3-2-1 Crack Spread
Okay, here’s how the margin works…
A refinery buys crude oil at one price and sells the gasoline and diesel it produces at another price.
The difference between those two numbers is called the crack spread; it’s essentially the refinery’s gross profit per barrel before operating costs.
Back in March, something remarkable happened.
First, you have to understand that the 3-2-1 crack spread is the single most important number in refining — and most investors have never heard of it.
Here’s how it works…
A refinery takes in three barrels of crude oil and “cracks” them into usable products.
The standard output is two barrels of gasoline and one barrel of diesel, and the crack spread is what those finished products are worth versus what the crude cost — the gross margin on every three barrels that run through the plant.
To put a little more perspective on this, keep in mind that historically, a crack spread above $15 per barrel is considered strongly profitable for most refiners.
Conversely, anything below $5/bbl is barely viable after accounting for operating costs (which run $3-5 per barrel).
That means right now, refiners are operating with cracks in the $25-28 range — nearly double the threshold for strong profitability.
It means that refiners trading 3-2-1 crack spread futures at the moment are locking in approximately $28 per barrel. These aren’t speculative bets, but rather professional hedges where refiners are voluntarily locking in that margin for future production.
Look, when the most sophisticated players in the market are willing to lock in this kind of profitability, they’re confident that it’ll remain elevated through the rest of the year.
But here’s where it gets really interesting for Gulf Coast refiners specifically — they have an additional advantage that international competitors don’t have.
Our Gulf refiners get to buy their crude feedstock at incredibly cheap WTI prices. In fact, crude was trading below $70 per barrel last Friday, which feels exorbitantly cheap considering the unprecedented geopolitical volatility taking place right now.
Now add another dynamic to this mix: rerouted shipping.
You see, with tanker traffic through the Strait of Hormuz constrained, it means longer trade routes around Africa. Of course, longer transit times mean more fuel consumption, and the diesel demand from this rerouting is pushing distillate crack spreads to levels we rarely see.
The spread between crude input and diesel output is even wider than the gasoline spread right now. And refineries are running at 93-95% utilization on the Gulf Coast — they’re making money hand-over-fist on every barrel they process.
This window isn’t sustainable forever, but you can bet this conflict won’t end anytime soon.
So, while oil producers get squeezed by WTI near $59, the refining sector is quietly delivering some of the most dramatic earnings reversals in the S&P 500 this year.
But is it really any surprise to see our downstream sector hauling in profits while the rest of the sector gets pulverized in the market at the whim of media headlines?
Companies that were logging operating losses twelve months ago are printing cash and boosting dividends.
Meanwhile, the media is fixated on bearish narratives crashing oil prices.
Although crack spreads have eased from their March peak as the Strait of Hormuz slowly reopens and Middle Eastern refining trickles back online, even Wall Street doesn’t see diesel margins fully normalizing until well into 2027.
That gap is still open, and the smart money is positioning itself accordingly.
Rockefeller built his empire on the spread between raw crude and finished products.
And just like him, we don’t need oil prices to spike to $100/bbl to profit.
Until next time,
