Salad Oil Scandal
One of the worst corporate scandals of its time. It occurred when Allied Crude Vegetable Oil Company discovered that banks would make loans secured by its salad oil inventory.
When the ships full of salad oil would arrive in the docks, inspectors would test it and confirm that the ship was full of salad oil. However, the company didn't remind anyone that oil floats on water. They had filled salad oil tanks with water and put a few feet of oil on top, fooling everyone. The company would even transfer oil to different tanks while taking inspectors out to lunch. In 1963, the scam was busted and over $175 million worth of salad oil was missing.
Investopedia Commentary
American Express took one of the biggest hits from the scandal, losing nearly $58 million and experiencing a 50% drop in AMEX stock as a result.
