Emerging-Market Crises: The Asian and Twin Crises
Week 11 analyses emerging-market financial crises, above all the Asian crisis of 1997-98. It explains why several Asian economies ran large current-account deficits that reversed sharply during the crisis, and the twin-crisis dynamic in which a currency depreciation and a banking crisis reinforce each other. It shows why large foreign-currency-denominated debt makes depreciation especially damaging by raising the domestic value of bank liabilities. Expect true/false on FX debt and pegs, and short essays on the current-account reversal and the fundamentalist-versus-panic debate.
What this chapter covers
- 01Current-account deficits financed by capital inflows, and the sharp reversal (sudden stop) when confidence collapses
- 02Currency crisis: intense pressure on a currency causing sharp depreciation, reserve loss or the collapse of a peg
- 03Twin crisis: a banking crisis and a currency crisis occurring together — common in emerging markets
- 04Common vulnerabilities: fixed exchange-rate pegs, heavy short-term foreign borrowing, unhedged foreign-currency debt
- 05Maturity mismatch and currency mismatch, often sustained by expected government bailouts (moral hazard)
- 06Why FX-denominated debt turns a depreciation into a banking crisis (liabilities rise in domestic-currency value)
- 07Two views on causes: the fundamentalist view (flawed financial system) versus the panic view (self-fulfilling capital flight)
- 08How the crisis unfolded in Thailand and spread, and the IMF-led policy responses and reforms
How foreign-currency debt turns a depreciation into insolvency
- +1Initial position. The USD 40m debt at 25 domestic units per dollar is worth 40 × 25 = 1000 in domestic currency. Net worth = assets − liabilities = 1200 − 1000 = 200 > 0, so the bank is solvent.
- +1The depreciation. The domestic currency falls from 25 to 35 per dollar — a 40% depreciation (10/25). Because the debt is denominated in dollars and unhedged, its domestic-currency value jumps to 40 × 35 = 1400, up 40%.
- +1New net worth. Assets are in domestic currency and unchanged at 1200, so net worth = 1200 − 1400 = −200 < 0. The bank is now insolvent purely because of the currency move — the depreciation inflated the domestic value of its liabilities while its assets did not keep pace.
- +1Twin-crisis mechanism. The currency crisis has caused a banking crisis. Distressed, insolvent banks and the capital outflows that accompany the loss of confidence put further downward pressure on the currency, deepening the depreciation and the banking losses — a self-reinforcing loop. Large unhedged foreign-currency debt under a peg is exactly what made the Asian crisis so destructive.
Key terms
- Current-account reversal (sudden stop)
- The sharp swing from a capital-inflow-financed current-account deficit to balance or surplus when foreign lenders stop rolling over funding, forcing depreciation and a collapse in imports. A defining feature of emerging-market crises.
- Currency crisis
- Intense pressure on a currency producing a sharp depreciation, a large loss of foreign-exchange reserves, or the collapse of a fixed-rate regime — often when a peg becomes indefensible.
- Twin crisis
- A banking crisis and a currency crisis occurring around the same time and reinforcing each other. Common in emerging markets, especially where banks hold large unhedged foreign-currency debt under a peg.
- Currency mismatch
- Holding liabilities in foreign currency while assets and revenues are in domestic currency. An unhedged mismatch means a depreciation raises the domestic value of debt without raising assets, destroying net worth.
- Maturity mismatch
- Funding long-term, illiquid assets with short-term foreign borrowing. When short-term lenders refuse to roll over, the borrower faces a funding crisis even if the underlying assets are sound.
- Fundamentalist vs panic view
- Two explanations of the Asian crisis: the fundamentalist view blames a flawed, under-regulated financial system with mismatches and moral hazard; the panic view blames a self-fulfilling shift in expectations that triggered capital flight despite sound fundamentals.
Emerging-Market Crises: The Asian and Twin Crises FAQ
Why does foreign-currency debt make a depreciation so dangerous?
Because it creates a currency mismatch. A bank or firm with unhedged foreign-currency debt but domestic-currency assets sees the domestic value of its liabilities jump when the currency depreciates, while its assets do not keep pace. Net worth can go from positive to negative purely from the exchange-rate move, turning a currency crisis into a banking crisis. This is the core reason the Asian crisis, with heavy short-term dollar borrowing under pegs, was so destructive.
What makes a crisis a 'twin' crisis?
A twin crisis is a banking crisis and a currency crisis happening together and feeding each other. A depreciation weakens banks with foreign-currency debt (banking crisis), and weak banks plus capital outflows put further pressure on the currency (currency crisis). Because each worsens the other, twin crises are deeper and harder to stop than either alone, and all three major developing-country crises since the 1980s were twin crises.
What was different about the Asian economies before their crisis?
Unlike the earlier Latin American debt crises, the Asian economies had rapid growth, low inflation and little government debt before 1997, which is partly why the crisis surprised observers. Their vulnerability lay elsewhere: fixed pegs to an appreciating dollar that hurt export competitiveness, maturity mismatches from short-term foreign borrowing funding long-term assets, and unhedged currency mismatches — mismatches often sustained by an expectation of government bailouts. The fundamentalist and panic views debate how much was flawed fundamentals versus self-fulfilling capital flight.
Can AI help me with emerging-market crises in ECON30005?
Yes. Sia can work the foreign-currency-debt net-worth calculation, trace the twin-crisis feedback loop, and help you structure an essay on the current-account reversal or the fundamentalist-versus-panic debate. Use it to rehearse the mechanism and the arguments; it does not sit graded assessment for you, and you should confirm the rules on Canvas.
Exam move
This final content week ties the subject together, so link it back to earlier chapters. Master the foreign-currency-debt mechanism numerically — a depreciation raises the domestic value of unhedged FX liabilities while domestic-currency assets are unchanged, so net worth can turn negative — and be able to draw the twin-crisis feedback loop (depreciation → weaker bank balance sheets → outflows → further depreciation). For essays, rehearse the current-account reversal story (inflows and deficits pre-crisis, sudden stop and reversal in crisis) and the fundamentalist-versus-panic debate, giving evidence for each side. Keep the common vulnerabilities (pegs, short-term foreign debt, currency and maturity mismatch, bailout-driven moral hazard) as a checklist. Watch the exchange-rate convention, which is the opposite of the PPP chapter's. This material rewards synthesis with the banking-risk and exchange-rate weeks. Confirm the exam structure on Canvas.
