Fear of Floating or Fear of Flying: Exchange Rate Policy in the New Millenium Eduardo Levy Yeyati The World Bank & Universidad Torcuato Di Tella December, 2006
Storyboard • The basics: The debate post-Bretton Woods • The tradeoff: Exchange rate regimes and the real economy • The evidence: Regimes in the 2000s • The FIT (float + inflation targeting) paradigm: natural evolution or fad? • Fear of flying: building a case for a proactive exchange rate policy
The basics • The real view (‘70s) • Trade (and welfare) gains vis à vis users of the peg currency vs. loss of the exchange rate as a shock absorber in the presence of nominal rigidities. • Pro peg Openness, propensity to trade, trade concentration • Pro float Incidence of real shocks
The basics • The political view (‘80s) • Bands, “tablitas” & other soft species: Exchange rate anchors as a “policy crutch” to compensate for the lack of monetary credibility or political power • Pro peg high inflation, weak governments
The basics • The financial view (‘90s) • The trilemma: as the world integrates, countries have to choose between monetary autonomy & a stable ER • The bipolar view: Exchange rate policy in emerging economies become more vulnerable to the limits imposed by the trilemma: hard peg or float • The unipolar view: Balance sheet effects due to currency mismatches limit the scope for expansionary devaluations Hard pegs
The tradeoff • Oversimplifying: • Fix vs. flex Enhanced monetary & fiscal discipline (lower inflation) at the cost of greater sensitivity to real shocks & output volatility… • …except under FD (contractionary devaluations) • Is this theoretical tradeoff validated by the evidence? • Yes
The tradeoff • Preliminary evaluation: • Pegs contribute to lower inflation expectations… • …at the cost of greater output volatility…

Argentina: Monetary (in)discipline Source: De la Torre-Schmukler-LY (2002)
The bipolar view after Argentina • Lack of external discipline by private markets Hard pegs do not lead to fiscal discipline • Fiscal dominance Hard pegs do not lead to monetary discipline • Is de jure dollarization hard enough?
Where do we stand? • Pegs are passé In most cases, inefficient short-term substitute for credibility • Hard pegs failed the test in Argentina • Learning to live with BS effects The (dynamic) scope for countercyclical exchange rate policy • The double D: Domestication and de-dollarization of sovereign debt • A unipolar view in reverse?
Exchange rate regimes in the 2000s: Classification • Key criterion: ER variability relative to forex intervention • The intervention dimension is key to characterized exchange rate policy (as opposed to the evolution of exchange rates) and its consequences

Emerging LATAM: A FIT paradigm? Source: LYS (2006)
The FIT paradigm • Natural evolution or this year’s model? • Less than a paradigm, more than a fad • Negative experience with alternative options • Inflation awareness CB autonomy, fiscal restraint • Decline in inflation –and dollar indexation– tilts the balance towards more flexibility • Inflation targets substitute for ER anchors • Still far from the benign neglect
The comeback of exchange rate policy? • Mercantilist interventions as a substitute for protection • Less specific than subsidies • Less prone to mismanagement & corruption • Fear of floating or fear of flying? • Invertion of the ER anchor problem: sustaining an undervalued currency • Instead of amplified recessions due to price rigidities… • …inflationary expansions fueled by positive real shocks. • Does it work? How?
Fear of flying: A characterization • Fear of floating’s underlying fears: • Contractionary devaluations (due to BS effects) and currency and debt crisis propensity • Dollar pricing, pass-through and inflation • Fear of flying: Leaning against the appreciation wind • Intervention to strenthen the demand for the foreign currency, to avoid/mitigate appreciation pressures

Taking stock • Dedollarization and debt reduction reduce the incidence of capital reversals • Soft FIT paradigm replaces the ER as nominal anchor • Fear of flying is an increasingly popular contender to drive domestic saving & investment (but not so much exports) • The exchange rate debate appears to have gone full circle to the issues of the 1970s

De facto regimes over the years: Classification • Exchange rate volatility (e): average of the absolute value of monthly changes in the exchange rate • Volatility of exchange rate changes (e ): standard deviation of monthly changes in the exchange rate • Volatility of reserves (R): average of the absolute value of monthly changes in international reserves relative to the monetary base of the previous month (both denominated in US dollars)
