Simplifying a complicated global economy

Aug 19,2023 - Last updated at Aug 19,2023

CAMBRIDGE — The global economy this year is full of puzzling surprises. Japan’s GDP growth is currently surpassing that of China, and July retail sales in the United States were double the consensus forecast, despite the US Federal Reserve pursuing one of the most concentrated rate-hiking cycles in decades.

In the United Kingdom, wage growth has risen to an annualized rate of 7.8 per cent and core inflation has remained high, even after 14 consecutive rate hikes by the Bank of England (with more to come). Meanwhile, Brazil and Chile have both cut interest rates, diverging from market expectations that the Fed will keep rates high for a prolonged period.

These oddities are just a few of many, and adding to the complexity are the uncertain implications of significant structural shifts on the horizon. These include the necessary transition to zero-carbon energy, the artificial-intelligence revolution, and various other innovation-driven changes. Add in geopolitical tensions and the retreat from economic and financial globalisation, and a wide range of potential scenarios opens up.

With so many moving pieces, and under such unconventional (and in many cases unprecedented) conditions, navigating this landscape would be challenging for anyone. That is when I find it particularly useful to return to a simple analytical framework that I learned early in my career as an economist. It is an extreme version of a “reduced-form equation” that economists use to focus on just a handful of key factors for predicting outcomes. These factors may not fully explain a phenomenon, but this strategy is better than relying on an impractically large and unwieldy set of factors.

In today’s context, my analytical approach poses a simple question: What single piece of information would be most valuable if I were stranded on a desert island for six months and wanted to understand what had happened to the global economy during that time? Given the current state of affairs, I would primarily want to know how the US had managed its growth-inflation dynamics. Or, more to the point, I would want to know whether the Fed had achieved a “soft landing” (bringing inflation back down toward its target without causing a sharp increase in unemployment).

This information is crucial, because the global economy currently lacks alternative engines. After all, the growth challenges facing China, the UK and the eurozone are not susceptible to quick policy fixes; a still-levered international financial system with high debt levels can ill afford another surge in US interest rates and strong dollar appreciation; Japan has yet to figure out how to exit its “yield-curve control” policy in a smooth manner; and the global economy continues to suffer gradual fragmentation.

At first glance, the prospects for the Fed achieving a soft landing do appear promising. Inflation has receded from its peak of over 9 per cent last year to slightly above 3 per cent, bringing it much closer to the 2 per cent target. At the same time, household spending continues to drive economic growth, and corporate balance sheets are solid. These conditions suggest that the US economy can absorb the cumulative impact of the Fed hiking rates by five percentage points, while also sidestepping the effects of faltering Chinese growth and Europe’s on-and-off flirtation with recession.

But, as the economic historian Niall Ferguson recently pointed out, “managing monetary policy is not in the least like flying a plane”. This simile seems especially applicable to the current Fed, for several reasons.

First, the Fed’s operating manual is outdated. Its “new monetary framework” is, in fact, suited for the prior decade of insufficient aggregate demand, rather than to this decade of insufficient aggregate supply. Second, the Fed’s landing zone is questionable, because the inflation target it is pursuing may well be too low given current structural and secular realities.

Third, with its excessive focus on immediate conditions, the Fed could end up neglecting the future wind patterns that it will encounter as its altitude changes. Fourth, it initiated its landing sequence late, following a long period in which it had mischaracterised inflation as “transitory” before finally implementing an intense cycle of rate hikes. And, finally, it is not clear whether the Fed has learned enough from its forecasting and communication mistakes to make the necessary course corrections.

Yes, the US economy has defied sceptics by maintaining robust growth above that of other major economies, and despite its notably higher interest rates and significant external headwinds. But the continuation of this exceptional performance hinges on the Fed’s ability to establish a low and stable inflation rate without triggering a recession. This is a delicate balancing act, and whatever happens will significantly influence the rest of the global economy and how policymakers navigate today’s extraordinary uncertainty.

My hope is that six months from now, we will celebrate the Fed’s success in achieving a soft landing and in positioning the US and the global economy to manage the exciting, but challenging, secular and strategic transitions ahead. My fear, however, is that the process will be much more complicated than many economic and market analysts expect, casting a once-avoidable shadow over one of the few bright spots in the global economy.
