There are no extreme "fixes" to secular declines in sales, profits, employment, tax revenues and asset prices.
The saying "never let a crisis go to waste" embodies several truths worth pondering as the stock market nears new highs. 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 second truth is that crises and solutions are generally symmetric: 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.
Speculative credit bubbles inevitably deflate, and this is universally viewed as a crisis, 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.
But what if the current speculative credit bubbles in junk bonds, stocks and other assets don't crash into crisis? 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?
A slow, steady decline is precisely what we can expect in an era of credit exhaustion, which I've covered recently: ( The Coming Global Financial Crisis: Debt Exhaustion). 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.
A funny thing happens when you depend on borrowing from the future (i.e. debt) to fund growth today: the new debt no longer boosts growth, as the returns on additional debt diminish. This leads to what I term credit/debt exhaustion: 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.
