Shutting down Hormuz visualized and put into perspective...

During the first oil shock in 1973, about 5 million barrels were removed from the global oil market. Daily global oil production was approximately 56 million barrels per day at the time, which means about 9% of the supply vanished.

Oil prices roughly quadrupled.

During the second oil shock in 1979, about 4 million barrels were removed from the global oil market. Daily global oil production was approximately 67 million barrels per day at the time, which means about 6% of the supply vanished.

Oil prices nearly tripled.

During the third oil shock in 1990, about 4.3 million barrels were removed from the global oil market. Daily global oil production was approximately 66 million barrels per day at the time, which means about 7% of the supply vanished.

Oil prices more than doubled.

If Iran were to shut down the Strait of Hormuz, it would remove a whopping 21 million barrels of oil from the global market. Today, global oil production is approximately 94 million barrels per day, which means about 22% of the worldwide oil supply could disappear.

As we can see in the chart below, it would be the largest oil supply shock the world has ever seen… by far.
