Uncertainty and currency crises: Evidence from survey data

Abstract: This paper studies empirically how uncertainty a¤ects speculation in the foreign exchange markets. We use the dispersion of survey forecasts of key macroeconomic variables to measure uncertainty about fundamentals. We …nd that uncertainty has a non-monotone e¤ect on exchange rate pressures: namely, uncertainty heightens speculative pressures when expected fundamentals are good and eases them when they are bad. We prove that this prediction arises from a broad class of currency crisis theories, ranging from …rs… Show more

“…The change in the non-fuel component is much less pronounced, as nominal rigidities are relatively high and firms end up absorbing almost entirely the increase in production costs driven by higher fuel prices. Results are in line with those reported by ECB (2010) and Jacquinot et al (2009). Differently from the oil supply and oil-specific demand shocks, the positive RW demand shock has a positive effect on euro area exports and GDP.…”

“…First, by inserting microfoundations of the supply of oil. One possibility is to follow Nakov and Pescatori (2009,2010), that endogenize OPEC decisions. On a different but complementary route, taking into account the role of oil inventories could be relevant for clearly distinguishing between precautionary demand and supply.…”

“…Consistent with predictions of theoretical currency crises models, Prati and Sbracia (2010) find a nonmonotonic link between uncertainty about fundamentals and the likelihood of a speculative currency attack. An increase in uncertainty raises the likelihood of a currency crisis when expected fundamentals are 'good' and lowers the likelihood of a currency crisis when expected fundamentals are 'bad'.…”

“…Thus, currency depreciates during these volatile periods. Further, higher volatility (uncertainty) increases the probability of a speculative attack on an existing exchange rate regime (see Prati and Sbracia, 2010) or agents demand foreign currency to hedge themselves against future policy shocks, thus depreciating This is currency. 11 From the viewpoint of classical economics, when Marshall-Lerner conditions are satisfied, the devaluation will lead to an improvement in the current account, hence an increase in aggregate demand.…”
