Conditions are ripe for repeat of 1970s stagflation and 2008 debt crisis

Warning signs are there for global economy, and central banks will be left in 
impossible position



In April, I warned that today’s extremely loose monetary and fiscal policies, 
when combined with a number of negative supply shocks, could result in 
1970s-style stagflation (high inflation alongside a recession). In fact, the 
risk today is even bigger than it was then.

After all, debt ratios in advanced economies and most emerging markets were 
much lower in the 1970s, which is why stagflation has not been associated with 
debt crises historically. If anything, unexpected inflation in the 1970s wiped 
out the real value of nominal debts at fixed rates, thus reducing many advanced 
economies’ public-debt burdens.

Conversely, during the 2007-08 financial crisis, high debt ratios (private and 
public) caused a severe debt crisis – as housing bubbles burst – but the 
ensuing recession led to low inflation, if not outright deflation. Owing to the 
credit crunch, there was a macro shock to aggregate demand, whereas the risks 
today are on the supply side.

We are thus left with the worst of both the stagflationary 1970s and the 
2007-10 period. Debt ratios are much higher than in the 1970s, and a mix of 
loose economic policies and negative supply shocks threatens to fuel inflation 
rather than deflation, setting the stage for the mother of stagflationary debt 
crises over the next few years.

The same loose policies that are feeding asset bubbles will continue to drive 
consumer price inflation

For now, loose monetary and fiscal policies will continue to fuel asset and 
credit bubbles, propelling a slow-motion train wreck. The warning signs are 
already apparent in today’s high price-to-earnings ratios, low equity risk 
premia, inflated housing and tech assets, and the irrational exuberance 
surrounding special purpose acquisition companies, the crypto sector, 
high-yield corporate debt, collateralised loan obligations, private equity, 
meme stocks, and runaway retail day trading. At some point, this boom will 
culminate in a Minsky moment (a sudden loss of confidence), and tighter 
monetary policies will trigger a bust and crash.

But in the meantime, the same loose policies that are feeding asset bubbles 
will continue to drive consumer price inflation, creating the conditions for 
stagflation whenever the next negative supply shocks arrive. Such shocks could 
follow from renewed protectionism; demographic ageing in advanced and emerging 
economies; immigration restrictions in advanced economies; the reshoring of 
manufacturing to high-cost regions; or the Balkanisation of global supply 
chains.

More broadly, the Sino-American decoupling threatens to fragment the global 
economy at a time when climate change and the Covid-19 pandemic are pushing 
national governments toward deeper self-reliance. Add to this the impact on 
production of increasingly frequent cyber-attacks on critical infrastructure, 
and the social and political backlash against inequality, and the recipe for 
macroeconomic disruption is complete.

Making matters worse, central banks have effectively lost their independence 
because they have been given little choice but to monetise massive fiscal 
deficits to forestall a debt crisis. With both public and private debts having 
soared, they are in a debt trap. As inflation rises over the next few years, 
central banks will face a dilemma. If they start phasing out unconventional 
policies and raising policy rates to fight inflation, they will risk triggering 
a massive debt crisis and severe recession; but if they maintain a loose 
monetary policy, they will risk double-digit inflation – and deep stagflation 
when the next negative supply shocks emerge.

But even in the second scenario, policymakers would not be able to prevent a 
debt crisis. While nominal government fixed-rate debt in advanced economies can 
be partly wiped out by unexpected inflation (as happened in the 1970s), 
emerging-market debts denominated in foreign currency would not be. Many of 
these governments would need to default and restructure their debts.

At the same time, private debts in advanced economies would become 
unsustainable (as they did after the global financial crisis), and their 
spreads relative to safer government bonds would spike, triggering a chain 
reaction of defaults. Highly leveraged corporations and their reckless 
shadow-bank creditors would be the first to fall, soon followed by indebted 
households and the banks that financed them.

To be sure, real long-term borrowing costs may initially fall if inflation 
rises unexpectedly and central banks are still behind the curve. But, over 
time, these costs will be pushed up by three factors. First, higher public and 
private debts will widen sovereign and private interest-rate spreads. Second, 
rising inflation and deepening uncertainty will drive up inflation risk premia. 
And, third, a rising misery index – the sum of the inflation and unemployment 
rate – eventually will demand a “Volcker moment.”

When former Fed chair Paul Volcker increased rates to tackle inflation in 
1980-82, the result was a severe double-dip recession in the US and a debt 
crisis and lost decade for Latin America. But now that global debt ratios are 
almost three times higher than in the early 1970s, any anti-inflationary policy 
would lead to a depression rather than a severe recession.

Under these conditions, central banks will be damned if they do and damned if 
they don’t, and many governments will be semi-insolvent and thus unable to bail 
out banks, corporations and households. The doom loop of sovereigns and banks 
in the eurozone after the global financial crisis will be repeated worldwide, 
sucking in households, corporations and shadow banks as well.

As matters stand, this slow-motion train wreck looks unavoidable. The Fed’s 
recent pivot from an ultra-dovish to a mostly dovish stance changes nothing. 
The Fed has been in a debt trap at least since December 2018, when a stock- and 
credit-market crash forced it to reverse its policy tightening a full year 
before Covid-19 struck. With inflation rising and stagflationary shocks 
looming, it is now even more ensnared.

So, too, are the European Central Bank, the Bank of Japan and the Bank of 
England. The stagflation of the 1970s will soon meet the debt crises of the 
post-2008 period. The question is not if but when.
