Here's a neat one: Fed (=central banks) getting less important since 2022.
Fed running the show?
In 2023, however, a remarkable paper by Sebastian Hillenbrand of Harvard Business School set the cat among the pigeons when he showed that the movements in US long-term interest rates could not be divorced from the Federal Reserve.
That relationship basically ended in 2022. Markets no longer place that much faith in the Fed, its influence quite literally waning.
"Markets are no longer taking guidance from the Fed about low long-term interest rates. Instead, they have priced in significant term premia, representing their requirement for higher returns for holding long-term government debt"
The Fed controls rates via speaking to the market, by validating information so that market participants trust it:
Hillenbrand thought the Fed was probably acting as a conduit of wider information. But markets only absorbed information about trends when they were confirmed by the central bank around meeting dates. The Fed, therefore, provided 'long-run guidance'
