With interest rates close to zero in the US and at zero in Japan and Europe governments will have no choice but to rely on quantitative easing if another recession arrives. This goes along with the MMT theory that as long as inflation doesn’t increase governments don’t need to worry about how much they borrow and spend.
There are risks of politicizing government spending and politicians doing as they please for political reasons. I’m curious what happens if inflation does rise, will the Fed stop buying gov bonds prompting politicians to rein in spending? Or will the power of the Fed be eroded?
