Now Japan is faced with the same difficult options that it faced twenty years ago and that China faces today. It can privatize government assets, or it can revert to the bad old days of consumption constraining policies. But if it constrains consumption growth and does not replace consumption with a surge in investment, how can it possibly grow except with explosive growth in the trade surplus? Domestic consumption, domestic investment, and the trade surplus are, after all, the only sources of demand growth for any economy.
So where does all this leave us? It’s all pretty clear to me. Of the two big trade deficit entities, neither the US nor peripheral Europe can allow their deficits to rise and we may even see, in the latter case, a sharp drop in the deficit. Of the three big surplus countries, Germany is reluctant to allow it’s surplus to decline by much, and certainly if it declines faster than the European deficits decline, Europe’s debt crisis will be much worse than ever.
China’s surplus can decline only if we see a very improbable decline in its savings rate or a very unwelcome increase in its investment rate – and my guess is that the internal pressures are for the savings rate to hold steady as the investment rate declines. And Japanese reluctance to solve its debt problems by privatization requires that it resolve them with an increase in the trade surplus.
Needless to say this isn’t going to work, and at least one of the above is going to be extremely disappointed. The “good” news is that if this conflict leads to much slower global growth, as it certainly will, the resulting reduction in commodity prices, including oil, will help absorb some of the changes in the trade imbalances as commodity exporting countries see their exports fall sharply. But I don’t see much other relief.
