When economic journalists speculate about looming inflation risks in the U.S. or any other country, they implicitly assume that each country’s inflation depends on that country’s fiscal or monetary policies, and perhaps the unemployment rate. Yet The Economist for March 3rd–9th shows approximately 1–2 percent inflation in the consumer prices index (CPI) for virtually all major economies.
Inflation rates were surprisingly similar regardless of whether countries had budget deficits larger than ours (Japan and China) or big surpluses (Norway and Hong Kong), regardless of whether central banks experimented with “quantitative easing” or not, and regardless of whether a country’s unemployment rate was 16.9 percent (Spain) or 1.3 percent (Thailand).
The latest year-to-year rise in the CPI was below 1 percent in Japan and Switzerland, 1.5 percent in Hong Kong and the Euro area, 1.6 percent in Canada and China, 1.8 percent in Sweden, 1.9 percent in Norway and Australia, 2 percent in South Koreas and 2.1 percent in the U.S. Among major countries, U.K. was on high side with inflation of 2.7 percent. Three economies with super-fast economic growth above 6 percent (India, Malaysia and the Philippines) do have slightly higher inflation—above 3 percent—but the CPI is up just 1.6 percent in one of them, namely China.
The remarkable similarity of CPI inflation rates is surprising since countries measure inflation differently and consume different mixes of goods and services. The fact that inflation rates are nonetheless so similar, and move up and down together, suggests that inflation is largely a global phenomenon. The U.S. may well have a disproportionate influence on global inflation, since it accounts for about 24 percent of global GDP and key commodities are priced in U.S. dollars. Yet U.S. inflation nonetheless goes up and down in synch with other major economies, as the graph shows.
