One truth is that extreme policies that would raise objections in typical times can be swept into law in the "we have to do something" panic of a crisis.
Thus wily insiders await (or trigger) a crisis which creates an opportunity for them to rush their self-serving "fix" into law before anyone grasps the long-term consequences.
a moderate era enables moderate solutions, crisis eras demand extreme solutions. Nobody calls for interest rates to fall to zero in eras of moderate economic growth, for example; such extreme policies may well derail the moderate growth by incentivizing risk-taking and excessive leverage.
even though the bubble was inflated by easy money, fraud, embezzlement and socializing risk and thus was entirely predictable.
The Federal Reserve and other central banks are ready for bubble-related financial crises: they have the extreme tools of zero-interest rate policy (ZIRP), negative-interest rate policy (NIRP), unlimited credit lines, unlimited liquidity, the purchase of trillions of dollars of assets, etc.
What if they deflate slowly, losing value steadily but with the occasional blip up to signal "the Fed has our back" and all is well?
, which I've covered recently: (). The central bank "solution" to runaway credit expansion that flowed into malinvestment was to lower interest rates to zero and enable tens of trillions in new debt. As a result, global debt has skyrocketed from $84 trillion to $250 trillion. Debt in China has blasted from $7 trillion 2008 to $40 trillion in 2018.
the new debt no longer boosts growth, as the returns on additional debt diminish. This leads to what I term : lenders can no longer find creditworthy borrowers, borrowers either don't want more debt or can't afford more debt. Whatever credit is issued is gambled in speculations that the current bubble du jour will continue indefinitely-- a bet guaranteed to fail spectacularly, as every speculative credit bubble eventually implodes.
Over time, marginal borrowers default as revenues and profits erode, and this triggers a corresponding erosion in employment and wages.
Not only do they lack the political will to launch extreme policies in a moderate decline, it would be unwise to empty the tool bag of extreme fixes at the first hint of trouble; what's left for the crisis to come?
Even worse, if the extreme policies fail to restore rapid growth and more importantly,, This will crush confidence and trigger the very crisis the authorities sought to forestall.
Moderate stagnation will not be reversed with moderate fixes (lowering interest rates a quarter of one percent, etc.), and any attempt to institute extreme policies will expose authorities' desperation right when confidence is vulnerable to collapse.
The Fed and other central banks are trapped in more ways than one.
