This means that at some point large-scale, persistent sterilized foreign-exchange intervention – amounting to several percentage points of GDP – would satisfy the additional demand for emerging-market assets and stop the inflows, even if interest-rate differentials remain. As sterilization induces issuance of domestic assets, global investors’ desire for diversification would be met without causing excessive currency appreciation, with all its collateral damage, in emerging markets.
这就意味着，在某些时间节点上，大规模的持续冲销式外汇干预（相当于GDP的几个百分点）将可以满足市场上对新兴市场资产的需求，从而使资本流入停止，哪怕利率差仍然存在。冲销过程就是国内资产对外发行的过程，它既可以满足全球投资者分散资产的需求，又不会导致本币过度升值，从而对新兴市场造成一系列打击。
