In short, because in 2Q2020 the Fed dropped the savings account cap of 6 monthly transfers to DDA accounts, M1 was redefined to include savings account.
Thus the massive ramp-up is the result of a ledger entry, not fundamentals. No need to jump.
The monthly YoY % change in M2 averaged 6.8% from 1960-2019, with a few stretches of 10-15% growth in the 70s and early 1980s. The avg from 2020-2021 of 17.9% reflects the 20%+ growth through March 2021 tapering to about 13% more recently.
Keep in mind, M2 creation isn't just the Fed but the result of commercial lending - Dr loans, Cr DDA accounts.
A lot of this money seems to be sitting on the sidelines.
