Sudden Stop, SS: Key Observation • Since the 1990s crises provoked by Sudden Stop (of capital inflows) have become more frequent. • SS involves large real currency depreciations, and have grave output and employment effects if the crisis involves the domestic banking system. • Empirical studies show that this dangerous combination is more likely to take place the larger is Domestic Liability Dollarization, DLD, • i.e., foreign-exchange denominated loans from domestic banks as a share of GDP.
SS: Further Empirical Analysis • DLD is dangerous because • banks tend to have short-term dollar liabilities (maturity mismatch). • DLD deteriorates banks’ balance sheets after large real depreciations (currency-denomination mismatch on the part of bank debtors). • Real depreciation is likely to be higher • the larger is the Current Account Deficit • the smaller is the share of Tradable Goods in output. • To prevent deleterious effects of bank runs under DLD it is necessary to have an effective Lender of Last Resort in dollars.

1997/1998: A Global SS for EMs • The Asian 1997 and Russian 1998 crises coordinated a major SS in most EMs. • It resulted in • much higher interest rates • large real currency depreciation • lower output growth and investment. • Its effects were long-lasting, and resulted in a transitory shrinkage of the EM bond market, and EM debt de-leveraging.

Asia/Russia Crises: Implications • External factors cannot be ignored, and may be crucial. • Financial globalization places EMs in the equivalent of a SS Tornado Alley, SS-TA. • Individual countries cannot move away from SS-TA, unless they become financially autarkical—which carries high costs. • Therefore, the relevant domestic policy options are • Lowering domestic financial vulnerabilities (e.g., de-dollarization), • Self-insurance (large stock of international reserves and/or contingent credit lines).

Phoenix Miracles: Implications • Phoenix Miracles suggest that SS is associated with drastic “capacity underutilization,” likely linked to financial factors. • It also suggest that crises are not “solvency crises,” but rather “liquidity crises.” • This reinforces earlier conclusion that relevant domestic policy options are • Lowering domestic financial vulnerabilities (e.g., de-dollarization), • Self-insurance (large stock of international reserves and/or contingent credit lines).
Monetary Policy • In essence, the problem is not monetary. • International credit suffers a drastic cut. • This cannot be offset by expanding credit from the central bank. • Unless central bank makes international reserves available to the rest of the economy: public or private sector. • This gives a rationale for the policy—clearly followed in Asia—of accumulating a large stock of international reserves as a form of self-insurance.
Monetary Policy (cont’d) • Empirical evidence shows that actually central banks’ reserves collapse after SS, much independently of the adopted exchange rate system • which, as noted, is a natural response to SS. • Typically, central banks lose international reserves by foreign exchange intervention, even though otherwise they prefer not to. • But this policy response is not necessarily first-best, e.g., because of market segmentation it could just give rise to Capital Flight. • Central bank could, alternatively, lend dollars to the export sector (like Brazil 2002).
Monetary Policy (cont’d) • Expansionary monetary policy through open market operations jacks up the nominal exchange rate and, in the short run, also the real exchange rate. • The latter has a positive impact on net exports and, on that account, alleviates the effects of SS (see Korea 1997/98, and Chile 1998/99). • However, under large DLD, real devaluation may worsen financial difficulties, resulting in lower output and employment.
Tight monetary policy? • Experience suggests that tight monetary policy has not interfered with necessary real exchange rate adjustment. • In all cases, in the short run the RER has exhibited large increase and overshooting. • However, excessive tightness may destroy domestic credit, unnecessarily deteriorating output and employment. (“You can’t push on a string but you can pull on a string!”); • but inflation is not an answer, because it also destroys real domestic credit, and has negative effect on output.
Tight monetary policy? (cont’d) • Domestic interest rates are not reliable indicators for assessing tightness because of • e.g., increase and volatility in country risk factors and inflationary expectations after SS. • Neither is output a good indicator because, e.g., typically SS is associated with changes in output levels and composition. Thus, “full-capacity output” is hard to assess. • Thus, in the short run after SS it may be desirable not to target interest rates or capacity utilization. • To prevent excessive tightness it may be advisable to temporarily peg the exchange rate to a sustainable level, and let money supply be endogenously determined. • For sustainability it is advisable to make sure that banks’ bailouts will not be needed.
Fiscal Policy • Expansive fiscal policy, especially credit to private sector, could alleviate the effects of SS. • However, typically both public and private sectors are subject to SS. • In which case the public sector can only implement expansionary fiscal policy on the strength of its stock of internationally liquid assets(e.g., international reserves), or international credit lines.
Government Policy: Need & Risks • Gov’t is a big player and major determinant of country risk. • Thus, e.g., a large stock of international reserves may send a strong signal that gov’t will use them to bail out banks and, thus, avoid interruption of domestic payments system. • Gov’t could implement ex post contracts that would be optimal ex ante, but that would be too costly to write ex ante. • However, the above policies may cause Moral Hazard on the part of the private sector. • Effective bank regulation is key to prevent Moral Hazard in that sector. • Moral Hazard justifies charging high interest rates during a SS • which should, however be significantly lower than the market’s.
