The Asian Financial Crisis of 1997: A Pattern Worth Knowing

The crisis began in Thailand in July 1997, when the government gave up defending the baht's peg to the dollar and let it float. The currency fell sharply, and the contagion spread across the region.

The conditions were familiar. Thailand had a large current account deficit, heavy short-term foreign debt, and a currency fixed at a level many considered overvalued. Foreign capital had flowed in during years of strong growth, and when confidence faded, it flowed out. The central bank spent reserves to defend the peg until it could not.

After Thailand, pressure spread to Indonesia, South Korea, Malaysia, and the Philippines. Currencies lost large shares of their value, banks and companies with foreign-currency debts faced insolvency, and economies contracted sharply. The IMF organized rescue programs, with conditions that were controversial.

The lessons apply to today's emerging markets. Pegs defended with reserves can break suddenly. Foreign-currency debt turns depreciation into a solvency problem. Contagion can hit countries with similar vulnerabilities, even if their own fundamentals differ somewhat.

For traders, the crisis shows how large and fast moves can be in managed currencies, and how stops fail when markets gap.

It also shows why risk premiums in high-yield currencies exist.

Practical step: list three vulnerability indicators from this crisis, and check them for one emerging market you follow today.

The foreign-currency debt part is what turned a devaluation into a full crisis. Companies earning in baht and owing in dollars saw their debts balloon overnight. The baht went from about 25 to the dollar before the float to around 50 within six months, so a dollar loan roughly doubled in local terms while revenues didn't. Banks that had borrowed short term in dollars and lent long term in baht were caught on both sides. That's the pattern I watch for in any emerging market today: how much of the borrowing is in foreign currency, and how much of it is short term. Those two numbers tell you how painful a depreciation would be.

Contagion is the lesson for traders. Countries with similar weaknesses got hit even before anyone checked their own numbers closely. Once Thailand broke, investors sold Indonesia, Malaysia, the Philippines and then South Korea, partly because they looked similar and partly because funds needed to cut exposure to the whole region. The same thing has happened since, for example in 2018 when the Turkish lira and Argentine peso crises spilled into other emerging currencies. If you hold a position in one EM currency and a similar country starts to crack, assume yours will be tested too. Reducing early costs a bit, waiting can cost a lot.
