With unprecedented stimulus stoking the global recovery, concerns are taking hold that inflation dynamics are about to shift. Higher costs from dislocated supply chains, a reduced service sector and pent up demand as vaccine adoption crests will likely pressure prices. However, many of these factors may be transitory. Once the economy adjusts to any new constraints, price pressure will likely moderate.
The biggest threat to financial normalization may be swelling government debt and the money printing that is helping monetize it. Could this debt buildup and related deficit spending push inflation and rates significantly higher?
Developed economy experience suggests the answer is no. Over the last two centuries, wealthy democracies have generally succeeded in preventing capital flight. Some of the most notable currency meltdowns and inflation spikes have been caused by loss of investor confidence. So, the main metric to monitor going forward is not the size of the debt, but the adequacy of the tax base to service it. If that materially erodes, then inflation could erupt.
Lessons From Japan
Japan is an advanced case of a developed country with an outlier debt to GDP ratio, yet inflation has been moderate for decades and its currency remains a safe haven.
Adam Posen, Head of the Peterson Institute and former member of the Bank of England’s Monetary Policy Committee, has concluded from his decades of research that sustainable debt is more a function of a country’s ability to tax.
Posen argues that for inflation to take off, debt monetization has to make its way into credit growth and create demand that significantly outstrips supply. Therefore, printing money to buy government debt is unlikely to fire up inflation, unless demand overwhelms supply and investors lose confidence and dump the currency.
In the 1990s, after the property and stock market crash in 1989, Japan’s fiscal and monetary policy was tame, resulting in anemic growth. But in 2001, Japan shifted to an unprecedented Quantitative Easing (QE) program that they let fizzle out in 2006. By 2010 it was resurrected, and in 2012 turned up several notches when Shinzo Abe became Prime Minister. He combined an ambitious program of fiscal, monetary and structural policies to accelerate the recovery. It worked.
While Japan’s per capital GDP was the lowest amongst G-7 peers from 1990-2002, it was the third highest after that, and also delivered the second highest productivity growth rate. Without massive QE, Japan would have been trapped in secular stagnation, as was confirmed by the lagging growth of the 1990s. Through a succession of QE programs, growth was revived.
The path of the stock market (Nikkei 250) captures the recovery as investor confidence and monetary policy gained traction and the market cheered.
