The Yen and Japan’s Trade Deficit
Exchange rates don’t drive trade flows, savings rates do.

According to conventional wisdom, a weaker currency should boost exports and reduce imports, but the real world doesn’t work that way. Take the trade figures out of Japan this week. Despite the yen losing 15% of its value against the dollar over the past year, Japan posted a record trade deficit of $5.7 billion in November.The usual caveat about a single month’s data applies, and most of the deficit is due to imports of fossil fuels post-Fukushima. Nevertheless, it’s striking that a depreciating currency hasn’t arrested a trend of declining trade surpluses that’s been underway for years.
In the 1980s, the situation was very different, with Japan running a large surplus and the U.S. in deficit. But the lesson was the same. Washington pushed Tokyo into the 1985 Plaza Accord, an agreement to strengthen the yen. But even after the Japanese currency appreciated by a whopping 87% over the following three years, the bilateral trade gap continued to grow.
The real driver of Japan’s exports, as Charles Wolf, Jr. wrote on these pages in 1989 and we excerpt on the following page, was a high savings rate due to demographic trends. As Japan’s population aged and savings declined, he predicted, Japan would become a mature creditor country and trade surpluses would give way to deficits. And so it is coming to pass.
Despite history’s repetition, the fact that exchange rates don’t drive trade flows hasn’t sunk in. The Bush and Obama Administrations pressured Beijing to appreciate the yuan by 37% since 2005, but the bilateral trade gap grew by 45% over the same period. China, like Japan in the 1980s, has a very high savings rate that causes trade surpluses, but its population is set to age even more rapidly than Japan’s. Why not let this supposed problem solve itself?
