On 10 October 1973 the Yom Kippur War begun, causing the 1973 oil crisis, tripling oil prices to US$10 per barrel, halting economic growth. Newly build ships sometimes went straight from the yard to lay-up. The situation worsened when the Suez Canal was reopened in 1975. Just when the situation began to improve in 1979, the Iranian Revolution caused the second oil crisis, causing oil prices to rise to US$30. Ships were sometimes sent to the breakers after being in service for only ten years. It took until the end of the 1980s before any profits were being made in oil transport.
