Do Firms Believe in Interest Rate Parity?

Using a broad sample of international corporate bond offerings, we provide evidence that corporate borrowers make opportunistic currency choices, in that they denominate the currency of their bonds in a manner that is inconsistent with a belief in either covered or uncovered interest rate parity. Using firm-level tests, we identify a number of characteristics of firms that engage in opportunistic behavior. We observe that large issuers located in developed markets with investment-grade ratings and low cash flow characterize those firms that are responsive to covered borrowing rate differences across currencies. Corporate responsiveness to uncovered borrowing rate differences appears more general. We observe that although the gains firms achieve through opportunistic currency denomination are economically significant, the yield differential tends to systematically decline after issuance. This finding suggests that opportunistic issuance by corporations may be a primary mechanism for driving covered interest yields toward parity.
