To buy time, the Chinese government is stimulating its growing economy and keeps it shielded from currency revaluations, in the hope that vibrant growth can continue. But they see the omens. And they are not good. On the one hand, China’s consumption-to-GDP ratio is falling; a sure sign that the domestic market cannot generate enough demand for China’s gigantic factories. On the other hand, their fiscal injections are causing real estate bubbles. If these are unchecked, they may burst and thus cause a catastrophic domestic unwinding. But how do you deflate a bubble without choking off growth? That was the multi-trillion dollar question that Alan Greenspan failed to answer. It is not clear that the Chinese authorities can.
