The 1997 Asian financial crisis: the crash that began in Thailand

When did the 1997 Asian financial crisis begin and end?

The 1997 Asian financial crisis began on 2 July 1997, when Thailand devalued the baht against the US dollar. Federal Reserve History dates the crisis from July 1997 to December 1998. Growth in the hardest-hit economies had exceeded 5% and often approached 10% before the shock, so the turn was abrupt. A regional stock market crash followed the currency fall within weeks.

Three phases help to read the record. The first, from July to October 1997, saw currencies fall in Thailand, Malaysia, the Philippines, and Indonesia. The second, from October to December 1997, brought the Hong Kong stock market fall and the South Korean debt emergency. The third, through 1998, brought deep recessions and spillovers to Russia and Brazil.

What caused the 1997 Asian financial crisis?

Four conditions came together: currency pegs, heavy short-term foreign borrowing, fast credit growth with weak supervision, and rising current account deficits (Federal Reserve History). When a peg failed, the local-currency value of dollar debts jumped, and firms and banks became insolvent. The detailed guide on Asian financial crisis causes explains each condition and how contagion linked them.

Wikipedia adds a number: foreign debt compared with GDP in the four large ASEAN economies rose from 100% to 167% between 1993 and 1996, then passed 180% at the worst of the crisis. A rising ratio signals that borrowing outruns the income that repays it. Readers can track the same ratio for any economy today.

Why did the Thai baht start the 1997 crash?

The baht was pegged at 25 to the US dollar, and Thailand ran out of foreign reserves while defending that rate. On 2 July 1997 it let the currency go. Thailand then faced both a balance-of-payments problem and a banking crisis (Federal Reserve History). The page on the Thai baht crisis tells the story of that first domino in detail.

The IMF unveiled a rescue package of more than $17 billion for Thailand on 11 August 1997, and approved $2.9 billion more on 20 August. Thailand shows how fast a currency problem becomes a market problem: the baht fell, banks weakened, and share prices followed. Later cases in the region followed a similar order.

How far did the 1997 crash spread across Asia?

Malaysia, the Philippines, Indonesia, and South Korea were directly affected (Federal Reserve History). South Korea reached the brink of default, and on 24 December 1997 a meeting hosted by the New York Fed led US banks to roll over short-term loans, which were restructured into medium-term loans by April 1998. Hong Kong defended its peg through a Hang Seng fall of 23% between 20 and 23 October 1997.

The damage differed by country. Indonesia lost 13.5% of its GDP in 1998 and Malaysia 6.2%, while Singapore recorded real growth of minus 2.2% (Wikipedia). These figures show a stock market crash turning into an economic one. Debt levels, bank strength, and early policy choices all shaped the outcome for each economy.

How did rescue packages answer the 1997 Asian financial crisis?

The IMF offered Indonesia a package of $23 billion and provided $58.4 billion to South Korea, after more than $17 billion for Thailand. Together with the World Bank, the Asian Development Bank, and several governments, the international community arranged loans of $118 billion for the three countries (Federal Reserve History). Each package came with reform conditions.

Malaysia chose a different path. It refused IMF aid, announced defensive measures in September 1998, and fixed the ringgit at 3.80 to the US dollar. A reader comparing the two paths sees different tools applied to the same shock, which is why the literature on the crisis returns to the contrast so often.

What lessons did ASEAN take from the 1997 Asian financial crisis?

ASEAN members, China, Japan, and South Korea built regional safety nets after the shock. A meeting of finance ministers in Chiang Mai on 6 May 2000 started the Chiang Mai Initiative, a regional reserve arrangement. The guide on ASEAN and the financial crisis follows what the region built and what it still watches.

The arrangement became multilateral on 24 March 2010, with a pool that began at $120 billion and grew to $240 billion in 2012 (Wikipedia). A pool of this kind gives a member a source of dollars at the moment foreign funding dries up, which is the problem that 1997 exposed.

How can you use the 1997 Asian financial crisis to read today’s risk?

Turn the record into a short checklist. Is the currency pegged or managed? How large is short-term foreign debt compared with reserves? Is credit growing faster than income? Do banks hold dollar liabilities without matching assets? As of October 2026 these four questions apply to any Asian market, and each answer is a number you can find in public data.
