In the aftermath of the devastating earthquake that has hit Japan, fears are growing over the potential for radiation leaks from damaged nuclear plants. Equity markets have been hit while FFA prices have also sustained significant losses. With the situation still unfolding, the longer term impact of the disaster on commodity markets is unclear, although some initial conclusions can be drawn. In the short term, shipping has been disrupted with 13 ports reported by Reuters to have closed, with some of these unlikely to be operational for several months or even years. Initial assessments by Macquarie and the Steel Index put production at five large steel mills in the worst-affected region at risk, accounting for 15-18 million tonnes (Mt) of annualized steel production capacity.
