The Wall Street Journal passed along warnings from the Bank of International Settlements (BIS) that central banks should start to curtail monetary expansion and that governments need to reduce their debt levels. The piece tells readers:

"The BIS has issued similar warnings in recent years concerning an overreliance on monetary policy, but its advice has gone largely unheeded."

It is worth noting that the BIS has been consistently wrong in prior years, warning as early as 2011 about the prospects of higher inflation due to expansionary monetary policy:

"But despite the obvious near-term price pressures, break-even inflation expectations at distant horizons remained relatively stable, suggesting that central banks’ long-term credibility was intact, at least for the time being.

"But controlling inflation in the long term will require policy tightening. And with short-term inflation up, that means a quicker normalisation of policy
rates."

Since that date, the major central banks of the world have been struggling with lower than desired inflation and doing whatever they could to raise the rate of inflation. It would have been helpful to readers to point out that the BIS has been hugely wrong in its past warnings, so people in policy positions appear to have been right to ignore them. This is likely still the case.
