Política monetária e bolhas financeiras: uma análise dos desafios na investigação e mitigação dos riscos

Abstract

This monograph analyzes the challenges involved in investigating and mitigating risks related to the formation of financial bubbles, considering the role of monetary policy in this context. It starts from the premise that monetary policy decisions directly influence financial markets and may, under certain conditions, contribute to imbalances that result in asset bubbles. The study discusses key concepts related to financial bubbles, identifies methodological difficulties in their early detection, and examines the monetary policy instruments used to prevent or mitigate their effects. The analysis offers a critical perspective on the role of central banks, highlighting the tension between economic stimulus and the preservation of financial stability. It concludes that, although monetary policy plays an important role in risk containment, its effectiveness depends on integration with other macroprudential tools and on preventive action based on sound diagnostics
