Interest Rate Risk Rewards in Stock Returns of Financial Corporations: Evidence from Germany

Abstract

The interest rate sensitivity of stock returns of financial and non-financial corporations is a well-known phenomenon. However, only little is known about the part of total stock returns that is attributable to the compensation an investor receives for being exposed to interest rate risk when investing in equity securities. We pursue here a benchmark portfolio approach, constructing benchmark portfolios having the same interest rate risk exposure as a particular stock. By studying the time series of returns of these assetspecific benchmarks, we find: i) Regardless of the industry considered, the interest rate risk benchmarks of German corporations have mostly earned a significantly positive reward. ii) Returns of interest rate risk benchmarks of financial institutions exceeded significantly those of non-financial corporations. iii) An investor willing to bear nothing but the average interest rate risk of German financial institutions would have earned a mean return of about or even exceeding 70% of the corresponding total stock returns. iv) Returns of the interest rate risk benchmarks of the German insurance sectorThe helpful comments of the editor are acknowledged with thanks. We especially thank an anonymous referee for several comments and suggestions that have significantly improved the paper. All remaining errors are our own.

Quantifying the Interest Rate Risk of Banks: Assumptions Do Matter

“…This approach was pioneered by Stone (1974) and has recently been applied by several authors to European financial corporations, including Oertmann et al . (2000) and Czaja et al . (2009a, 2009b).…”

“…7 There are also numerous models and papers that analyse the interest rate sensitivity of (exchange-traded) banks based on stock returns rather than on accounting-based regulatory data. This approach was pioneered byStone (1974) and has recently been applied by several authors to European financial corporations, includingOertmann et al (2000) andCzaja et al (2009aCzaja et al ( , 2009b. However, because in many countries (including Germany) most banks are not listed, this approach to analysing the interest rate risk is not universally applicable for supervisory purposes.…”

Fundamental Analysis in China: An Empirical Study of the Relationship between Financial Ratios and Stock Prices

“…Adjustment of all benchmark rates can affect a stock price. For example, the investment value of a security may decrease during an increasing period, bringing about stock price dropping; in the contrary situation, the result shows an opposite direction [8]. Numerous empirical studies exist on the potential influence of inflation/level of GDP on the evolution of the assets' price (see Weale and Wieladek [9] for a recent analysis of these aspects).…”

Testing the Excess Return Hypothesis: The Canadian Case

“…The study confirmed that stock returns are partially predictable while rejecting the random walk model. In another study, Czaja and Scholz (2009) examined the sensitivity of German stock returns to interest rate changes and concluded that the industry curvature and, to a lesser extent, the slope of the term structure, are useful in predicting variations in stock returns. The study also found that interest rate risk was of greater relevance for financial institutions than non-financial institutions.…”
