Inflows and Outflows of Capital: Do They Affect You?by The Economist Magazine
Vast capital inflows can harm economies in several ways. Not only can they inflate asset bubbles and spur excessive borrowing, but they can also cause a steep rise in the exchange rate, damaging the competitiveness of export sectors. If a country already has a current-account deficit this will make it even more vulnerable to a quick reversal of capital. On the other hand, if central banks intervene to hold down their currencies, the build-up of reserves can lead to excessively loose monetary conditions and rising inflation.
