Is a central bank able to influence stock market returns? In order to answer this question, we test for cointegration between stock market returns and central bank interest rates in Germany for the period 1974 – 2003. Problems related to spurious regression could arise from the mixed order of integration of the series used, from reverse causation between the variables and from the lack of a long run relationship among the variables of the model. We address these problems by applying the bounds testing approach and autoregressive distributed lag models developed by Pesaran and others. The empirical results are also compared with those obtained from a more standard econometric approach, the Johansen procedure. Seen on the whole, we cannot empirically reject the view that the Bundesbank – and then the ECB – have had a significant short- and long-run impact on stock market returns. We conclude that short-term rates drive stock market returns but not vice versa. But the results are confined to a single stock market return measure, namely dividend growth.
