The Use of Foreign Currency Derivatives and Firm Market Value

TLDR

The study investigates how foreign currency derivatives used by large U.S. nonfinancial firms between 1990 and 1995 affect firm value. The authors analyze 720 firms by measuring the ratio of foreign currency derivatives to foreign sales as a proxy for hedged exposure, revealing significant dispersion in hedge ratios.

Abstract

This paper examines the use of foreign currency derivatives (FCDs) by a sample of 720 large U.S. nonfinancial firms between 1990 and 1995 and its potential impact on firm value. Using Tobin's Q as an approximation of a firm's market valuation, we find a positive relationship between firm value and the use of FCDs. The hedging premium is statistically and economically significant mostly after 1993 and is on average 5.7\% of firm value. This result is robust to a) controls for size, profitability, leverage, growth opportunities, ability to access financial markets, industrial and geographical diversification, credit quality, industry classification (4-digit SIC), year-dummies and firm fixed-effects; b) the use of a weight-adjusted industry Tobin's Q and other measures of value, such as the market to book and the market to sales ratios; and, c) alternative estimation techniques that handle the potential impact of outliers. Using the ratio of foreign currency derivatives to foreign sales as a proxy for the percentage of exposure that a firm hedges, we observe a significant dispersion in our measure of the hedge ratio. In univariate tests we find a nonlinear relationship between Q and our proxy. However, firm-specific factors explain this relationship in multivariate tests and it appears that firms are hedging optimally.
