Economists used to think that financial factors are not important in the business cycle, but the 2008 global financial crisis has made it apparent that financial cycle plays a much larger role in macroeconomic dynamics than anticipated. Against this background, economists endeavor to introduce financial factors into macroeconomic models. In this paper, we incorporate financial cycle into a four‐equation model to study the linkages and interactions between financial cycle, business cycle and monetary policy. The results suggest that financial cycle plays a significant role in the business cycle, and that financial cycle shock has become a main driving force for macroeconomic fluctuations, especially during times of financial instability. In addition, by comparing the performance of the finance‐augmented Taylor rule with that of the conventional Taylor rule, we find that both the financial system and the real economy will be better stabilized under the finance‐augmented Taylor rule. This result adds new evidence to the argument that monetary policy has an important role in safeguarding the financial system and that financial stability should be adopted as a target for monetary policy.
