Trump Helps Make Japan Normal Again

Speculation over the next president’s budgets has driven down the yen -- a reminder of the limits to purely domestic economic policies.

President-elect Donald Trump isn’t even in office yet, and he’s already delivered a helpful boost to the economy -- the Japanese economy. At the end of a year of gloomy announcements, the Bank of Japan has raised its growth forecast for next year, and Trump deserves much of the credit.

The main reason for the BOJ’s improving mood is the fall in the yen, which will help boost Japanese exports. And the main reason for the fall in the yen? The strong dollar -- reflecting in part the prospect of Trumpian tax cuts and new infrastructure investment, which would increase U.S. public borrowing and accelerate the coming rise in U.S. interest rates.

The BOJ’s optimism, to be sure, is relative. The government’s revised forecasts put growth next year at 1.5 percent rather than 1.2 percent. That’s hardly spectacular.  Yet as recently as September, with the policy interest rate already negative and the economy failing to respond, the outlook seemed bleaker.

Despite the improvement, the central bank says it intends to keep monetary policy unchanged -- meaning heavily expansionary. Overnight interest rates will remain at minus 0.1 percent, with 10-year bond yields capped at around zero. And the BOJ will maintain its aggressive bond- and equity-purchase programs.

With inflation still close to zero despite four years of such extraordinary measures, Japan’s economic recovery is still a long way off. But confidence matters a lot in breaking out of a low-growth trap, and every little bit helps.

Something else to ponder: The link from speculation over Trump’s budgets to the outlook for Japan is a timely reminder of the limits of purely domestic economic policy. Economies are connected in subtle and sometimes unpredictable ways through global markets for goods and capital. That’s why a possible side-effect of expanding domestic demand in the U.S. could be a reduction in exporters’ competitiveness from a stronger currency.

It’s not necessarily a problem -- unless, perish the thought, someone were to make it one by accusing other countries of unfair trade practices.
