CAMBRIDGE – Japan’s new government, led by Prime Minister Shinzo Abe, could be about to shoot itself in the foot. Seeking to boost economic growth, the authorities may soon destroy their one great advantage: the low rate of interest on government debt and private borrowing. If that happens, Japanese conditions will most likely be worse at the end of Abe’s term than they are today.
The interest rate on Japan’s ten-year government bonds is now less than 1% – the lowest in the world, despite a very high level of government debt and annual budget deficits. Indeed, Japan’s debt is now roughly 230% of GDP, higher than that of Greece (175% of GDP) and nearly twice that of Italy (125% of GDP). The annual budget deficit is nearly 10% of GDP, higher than any of the eurozone countries. With nominal GDP stagnating, that deficit is causing the debt/GDP ratio to rise by 10% annually.
Japan’s government is able to pay such a low rate of interest because domestic prices have been falling for more than a decade, while the yen has been strengthening against other major currencies. Domestic deflation means that the real interest rate on Japanese bonds is higher than the nominal rate. The yen’s rising value raises the yield on Japanese bonds relative to the yield on bonds denominated in other currencies.
That may be about to come to an end. Abe has demanded that the Bank of Japan pursue a quantitative-easing strategy that will deliver an inflation rate of 2-3% and weaken the yen. He will soon appoint a new BOJ governor and two deputy governors, who will, one presumes, be committed to this goal.
