Last year, the daily cost of hiring an oil supertanker (known as a Very Large Crude Carrier, or VLCC) to sail from the Persian Gulf to China was just $65,000, according to Clarksons, a London-based research firm.
By the time the Iran war was about to begin, that cost had climbed to $230,000 per day.
Now? It costs $1.6 million per day to hire a VLCC for that route, according to Clarksons.
All of this -- the cost to hire a tanker, exorbitant payments to sailors and surging insurance rates -- is making it more expensive for consumers and businesses around the world.
It used to cost just $2 per barrel to get crude out of the Persian Gulf. Now, that cost has spiraled to about $33, according to Tom Kloza, chief energy adviser at Gulf Oil.
"We're getting a reasonable amount of crude out, but that's misleading because the cost of that crude exiting is incredible," he said.
