A sleuth’s guide to the coming wave of corporate fraud

The bad news just keeps coming. Ten months after America’s stockmarket peaked, its big technology companies have suffered another rout. Hopes that the Federal Reserve might change course have been dashed; interest rates are set to rise by more than previously thought. The bond market is screaming recession. Could things get any worse? The answer is yes. Stockmarket booms of the sort that crested in January tend to engender fraud. Bad times like those that lie ahead reveal it.

“There is an inverse relationship between interest rates and dishonesty,” says Carson Block, a short-seller. Quite so. A decade of ultra-low borrowing costs has encouraged companies to load up on cheap debt. And debt can hide a lot of misdeeds. They are uncovered when credit dries up. The global financial crisis of 2007-09 exposed fraud and negligence in mortgage lending. The stockmarket bust of the early 2000s unmasked the deceptions of the dotcom bonanza and the book-cooking at Enron, WorldCom and Global Crossing. Those with longer memories in Britain will recall the Polly Peck and Maxwell scandals at the end of the go-go 1980s.
