Capital Flows and Hot Money

How money flows between countries through investment and lending, why sudden reversals can cause crises, and how countries manage the risk.

Money moves between countries not only to pay for goods and services, but also for investment. These movements are called capital flows, and they can have a big effect on currencies, interest rates and financial stability.

Types of capital flows

Foreign direct investment: buying a large stake in a business or building factories abroad. It tends to be long-term and stable.
Portfolio investment: buying shares and bonds. It can move in and out quickly.
Bank lending: loans from foreign banks.

Hot money

Short-term, fast-moving portfolio flows are sometimes called hot money. Investors move money to countries offering higher returns and pull it out quickly when conditions change.

Sudden stops

A sudden stop occurs when foreign capital inflows abruptly halt or reverse. This can cause:

A sharp fall in the currency.
Rising interest rates.
Falling stock and bond prices.
Difficulty repaying foreign-currency debts.

The 1997 Asian financial crisis was partly driven by large inflows followed by sudden outflows.

The taper tantrum

In May 2013, the U.S. Federal Reserve hinted it might slow its bond purchases. Investors pulled money from emerging markets, and several currencies, including the Indian rupee, fell sharply. India was grouped among the “fragile five” economies with large current account deficits. India responded by raising interest rates and attracting special foreign currency deposits, and later built up large foreign exchange reserves.

Why reserves help

A country holds large foreign exchange reserves. When foreign investors suddenly pull out, the central bank can sell some reserves to buy its own currency, slowing its fall and calming markets. Countries with small reserves have fewer tools and may face deeper crises.

Managing the risks

Countries manage capital flow risks through:

Foreign exchange reserves.
Flexible exchange rates.
Capital flow management measures, such as limits on certain inflows. The IMF, once opposed to such controls, now accepts they can be useful in some circumstances.
Sound fiscal and external positions.

Thinking all foreign money is equally stable

Long-term direct investment in factories is much harder to pull out quickly than portfolio investment in shares and bonds. The type of capital flow matters for financial stability.

Key takeaways

Capital flows include direct investment, portfolio investment and bank lending.
Hot money is short-term portfolio money that moves quickly.
Sudden stops can cause currency falls and crises, as in 1997 and the 2013 taper tantrum.
Reserves, flexible exchange rates and capital flow measures help manage risks.
