According to CoinMeta, and as reported by The Wall Street Journal, Iran's "shadow tanker" fleet no longer has any oil to transport. For most of the duration of the conflict, Iran possessed dozens of tankers loaded with millions of barrels of crude oil, safely anchored in Asian waters. Tehran earned billions of dollars in much-needed cash by continuously selling this crude oil. However, by mid-October, these maritime reserves had been completely depleted, due to the U.S. Navy's blockade that hindered Iran's ability to replenish its crude oil supply.
