In November 2020, as markets reached record valuations – despite a weak economy, divided Congress, and trade wars – Bloomberg called Powell "Wall Street's Head of State", as a reflection of how dominant Powell's actions were on asset prices, and how profitable his actions were for Wall Street.[24] On 19 November 2020, Treasury secretary Steve Mnuchin got into an "unprecedented spat" with Powell over the return of unused crisis funds, to which Powell relented.[80] In December 2020, Powell defended high asset prices by invoking the controversial Fed model, saying: "Admittedly P/Es are high but that's maybe not as relevant in a world where we think the 10-year Treasury is going to be lower than it's been historically from a return perspective".[25] The author of the Fed model, Dr. Edward Yardeni, said Powell's actions could form the greatest financial bubble in history,[81] while the Wall Street Journal described Powell's comparison as an attempt to "rewrite the laws of investing".[26]

In January 2021, investor Jeremy Grantham said that markets were in an "epic bubble",[82] and wrote that "All three of Powell’s predecessors claimed that the asset prices they helped inflate in turn aided the economy through the wealth effect", before eventually collapsing.[83][84] In reviewing 2020, BNN Bloomberg noted that Powell showed almost "complete dominance over financial markets", despite the challenges encountered in the year.[21]

Waiting for the Last Dance, Jeremy Grantham

Yet the market is much higher today than it was last fall when the economy looked fine and unemployment was at a historic low. Today the P/E ratio of the market is in the top few percent of the historical range and the economy is in the worst few percent. This is completely without precedent and may even be a better measure of speculative intensity than any SPAC.

This time, more than in any previous bubble, investors are relying on accommodative monetary conditions and zero real rates extrapolated indefinitely. This has in theory a similar effect to assuming peak economic performance forever: it can be used to justify much lower yields on all assets and therefore correspondingly higher asset prices. But neither perfect economic conditions nor perfect financial conditions can last forever, and there’s the rub.
