insurance rates for oil tankers of 0.25% of ship's value increase to 1-2% in Iran war for Straits of Hormuz, US Development Finance Corporation says it will offer reinsurance to insurers to cap the price shippers pay. There is no shortage of insurers to insure ships for the Straits of Hormuz, Lloyd's of London is open for business. Shipping executives say they are concerned about the safety of the crew members, that it is about more than insurance. About 1000 shipos are waiting outside the Straits of Hormuz to make the journey through the Straits. At its narrowest point it is only 19 miles making it possible to plant mines in that area. The US is taking action and has sunk many Iranian minelayer ships.
