The Fed’s zero lower bound policies have dislodged credit risk as the primary concern for investors, only to replace it with a major technical headache: interest rate risk. If rates remain too low for too long, financial stability suffers as investors reach for yield, companies lever up, and lending standards decline. The greatest of financial stability risks is probably the least discussed among those that matter at the Fed: the deterioration in trading volumes. As such, we suspect that the longer low rates persist, the worse the unwind of QE may be. And it may, in fact, already be too late. As events in the past two weeks have shown, credit markets also appear vulnerable to a rise in rates that occurs too quickly or in a chaotic fashion. Moreover, to the extent that issuers sense demand may be waning for bonds, there’s a distinct possibility the pace of supply increases precisely at the same time that demand decreases. Invariably, it’s this sort of dynamic that ends in tears.
