America’s July jobs report has shown the dilemma central banks and governments face in the most inflationary period since the two oil shocks and Vietnam War in the late 1970s and early ’80s.

More than half a million jobs were created in July and US unemployment fell to 3.5%. That’s despite the US Federal Reserve putting interest rates up to 2.25-2.5% from 0.1% in just seven months.

Monetary policy is slow to work at the best of times, but the central bank’s “shock and awe” approach of large-scale rate rises is partly designed to change consumer and business behaviour as rapidly as possible. There’s no evidence it’s worked so far in terms of employment outcomes — not in the US, where unemployment has fallen from 4% to 3.5% since the start of the year, and the three months to the end of July saw nearly 1.3 million new jobs created. And not in Australia, the UK, Europe, Canada and other developed economies. Jobs growth just keeps on coming.

What hasn’t been coming, though, is real wages growth. Even though US inflation has risen to 9.1% in June (there’s an update for July this week) from 7.4% in January, US hourly wages growth has slowed from 5.7% in January to 5.2% in July, meaning tens of millions of US workers are seeing a growing fall in real wages.

US markets are now tipping another 0.75% rise from the Fed at its next meeting, but there’s no meeting now until September 20-21. August is reserved for the annual Jackson Hole Symposium in Wyoming run by the Kansas Fed on August 25-27. That means the Fed will have both the July and August consumer inflation data, allowing some perspective on the trajectory of inflation — though if the CPI jumps well past 10%, it may force a very rare between-meetings rate increase.

High unemployment is a toxic and immiserating phenomenon that leaves permanent scars on communities. But it’s also a very strange problem to have, reflecting just how unusual our current economic circumstances are, when inflation is caused not by excess demand of wage-price spirals but external factors beyond the capacity of governments or central banks to address.

It’s also a taste, perhaps, of what the future will increasingly look like: low unemployment driven by the fact that there’s a growing global shortage of workers; supply chain dislocation driven by weather extremes (and, perhaps, novel diseases) caused by the climate emergency; market power wielded by giant corporations against workers and consumers.

Central banks, however, only have one tool, interest rates, with which to clobber demand, rather than address the primary causes of inflation. So far, the jobs market has shown no evidence that clobbering demand has so far had any impact. Central banks like the Federal Reserve and the Reserve Bank might need to hit and keep hitting demand until they kill it. If only demand were actually the problem.
