In response to the economic impact of the COVID-19 pandemic, the U.S. Federal Reserve and central banks worldwide have deployed tools that past policymakers and economists might have considered radical. Programmes like large-scale securities purchases and a new policy framework remain a source of confusion for investors, journalists and ordinary citizens alike. Twenty-First Century Monetary Policy demystifies these opaque techniques to reveal how economic ideas, historical events and political forces have transformed the Fed’s policies over several decades. From the stagflation of the 1970s to the Great Recession and the recent pandemic, Ben S. Bernanke masterfully examines how the Fed’s policies—and the institution itself—may change as it grapples with persistently low interest rates, systemic financial risk, rapid technological change and polarised politics. With unparalleled depth of expertise and robust historical sweep, Twenty-First Century Monetary Policy is a must-read for anyone interested in understanding modern finance, investments or U.S. economic policy.
