When central banks started raising interest rates in reaction to the spike in inflation which followed the COVID-19 epidemic, they put an end to a more than a decade of "low for longer" interest rates to which the financial sector had adjusted their balance sheets and business models. The resulting "new monetary order" has required all parts of the financial sector to make serious adjustments. The fate of the US and Swiss banks caught up in the March 2023 "bank turmoil" can be seen as a cautionary tale for those who do not adjust in a timely fashion. This book reviews how the financial sector evolved during "low for longer" and examines how monetary policy, financial regulation and supervision, the banking and the non-bank financial sectors can be expected to evolve under this new order.
