Do you mean fiscal policy? You absolutely can infuse trillions of dollars into the economy without causing inflation after the economy takes a $4T hit from a pandemic; the government spending will be what prevents disastrous deflation.

People worry about inflation, but forget how awful deflation is.

(And on a side-rant, it’s really bizarre how the hyperinflation of Weimar Germany is cited as enabling the rise of the Nazi party. The timing doesn’t work. They came to power during the depression-era deflation.)
