The Council of Foreign Relations has some bad news for Australia:
Over the past two years, as our left-hand figure above shows, foreign portfolio investors have piled prodigiously into Chinese assets, helping to support the RMB. But history suggests this trend is about to reverse. While inflows have been rising, Chinese stocks have been tumbling—they are down over 20 percent from their January peak. Dreadful performance like this typically drives funds out of emerging markets. We may be seeing the beginning of such outflows in China.
Repatriation of liquid foreign capital will make it far more challenging for China to keep its currency up. Of course, China could change course and let it fall, but that risks exacerbating the foreign-debt burden of its highly leveraged corporates. It could raise interest rates, but that would further slow a slowing economy. It could, to keep capital at home, demand higher returns on its foreign lending, but that would mean sacrificing its efforts to subsidize its companies operating abroad, as well those aimed at putting dollars to the service of geostrategic objectives—like Belt and Road.
