The 1963 Great Salad Oil Scandal

The 1963 Great Salad Oil Scandal

@Dr. Arthur Grift · June 13, 2026

Wall Street once nearly collapsed because of a man who understood salad dressing better than the banks. Anthony De Angelis realized that since oil floats on water, you don't need a full tank to look rich.

He filled massive vats with water and topped them with a thin layer of soybean oil. When inspectors dipped their sticks, they saw "liquid gold" and approved millions in loans based on inventory that didn't exist.

This "ghost oil" scam almost took down American Express and the Stock Exchange before anyone finally bothered to check the bottom of the barrel.

Wait, why was a credit card company even messing with salad oil?

Back then, American Express wasn't just about credit cards. They ran a side hustle called "field warehousing," acting as the world's most expensive babysitters for industrial goods.

They would slap their logo on a warehouse and pinky-promise banks that the inventory inside was legit. Their signature was the "gold standard" that turned a vat of liquid into a bank loan.

Amex got so lazy they eventually signed receipts for more soybean oil than the entire United States actually produced. They were basically selling their reputation to a con artist for a quick fee.

Wait, nobody noticed they'd surpassed the entire nation's oil supply?

It was a masterpiece of "not my job" energy. Inspectors would climb the vats, dip a stick, see oil on the tip, and call it a day. They never checked if that "liquid gold" was just a two-inch layer floating on a sea of cheap water.

The paperwork was also scattered across dozens of different banks. Since everyone trusted the American Express logo like a holy relic, nobody bothered to add the numbers up until the bubble finally popped.

By the time they did the math, the "paper oil" Amex had guaranteed was worth more than every real soybean in America. It was the ultimate "fake it 'til you break the global economy" move.

What was the specific pin that finally popped this giant oily balloon?

De Angelis wasn't just hiding water; he was a high-stakes gambler. He used his fake oil loans to bet big on the soybean market, hoping to drive prices up and become the undisputed Oil King.

But the market eventually turned against him. When prices dipped, his brokers demanded cash he didn't have. He went bankrupt practically overnight.

With the money gone, the creditors finally rushed to the warehouses to claim their liquid gold. Instead of a fortune, they found 1.8 billion pounds of missing oil and a lot of very confused inspectors holding wet sticks.

Did they actually throw this Oil King in jail for the mess?

De Angelis didn't ride off into the sunset. He got 20 years in prison, serving seven. When you almost bankrupt American Express and cause a NYSE panic, the government loses its sense of humor.

The kicker? This wasn't his first rodeo. He had already been caught selling sub-par meat to school lunch programs. He was a career con artist who 'failed up' until hitting the ceiling of global finance.

Even after jail, he couldn't stop. He was later caught in another scam involving more fake food certificates. Some people just love the smell of a bad deal.
