A year ago airline CEO’s were routinely invited to appear on CNBC’s Fast Money and Mad Money shows.  The one question they were always asked was their level of fuel hedging.  CNBC commentators praised Southwest Airlines for its decision to hedge fuel by locking in at such a low cost.  But CNBC commentators never discussed the possibility of those hedges going wrong.  And in most cases, they are.

From Marketwatch, China Eastern just reported fuel hedging losses of $906 million.  Hedges are very common in multi-national companies, but when it comes down to it, they are a gamble.  And those gambles can work against you too!

China Eastern Airlines said Sunday it suffered a fair value loss of 6.2 billion yuan ($906 million) on fuel hedges last year and that operations have been affected by deteriorating business conditions since the second half, warning it would report a “significant loss” for 2008. The Shanghai-based airline said losses were accumulated under an “industry-wide crisis.” It said its aviation-fuel hedges ballooned into losses after crude oil prices fell sharply.
