The past quarter-century has been a tumultuous period for the global economy, characterized by significant events that have reshaped monetary policy and economic stability.The Great Financial Crisis (GFC), the Covid-19 pandemic, and a subsequent surge in inflation have tested the resilience of economies worldwide, revealing both the strengths and limitations of monetary policy.Since the turn of the 21st century, the GFC marked a pivotal moment, ending the era known as the Great Moderation, which was characterized by low volatility in output and inflation in advanced economies (AEs).
