But what do these numbers really mean?

I don’t think the near-term rebound will be merely a statistical phenomenon resulting from the low base in 2020. 

Rather, it reflects a massive increase in involuntary savings, monetary and fiscal stimulus, and the targeted generosity of bailout programs. 

How long it will last will depend on a complex combination of factors, including the speed at which personal savings are spent down, the continuance (or suspension) of government support, inflationary signals, and the behavior of markets – which themselves will be influenced by all of the above.
