Abstract

Large shifts in countries’ external current account positions can be disruptive, often reflecting sudden stops in the flows of external finance and leading to exchange rate and banking crises. As a result, an empirical literature has emerged on the sustainability of, and the determinants of large swings in, current account positions. We shed further light on this issue by testing for the presence of unit roots in the current account balance-to-GDP ratios of a large set of mature and emerging-market economies using a methodology that allows for structural breaks in intercepts and trends. We then construct a chronology of current account reversals that is consistent with sustainability of external positions and use it to estimate the factors explaining the likelihood and magnitude of such reversals using a selection model with ordered probit in the first stage. We find that most of the factors that explain the probability of reversals, such as trends in capital flows, in the budget balance and in external positions, also influence their magnitude. But there are a few exceptions. For instance, the stance of monetary policy and the magnitude of external imbalances prior to a reversal seem to be more powerful predictors of the probability of reversals than of their magnitude. Les déséquilibres mondiaux sont-ils viables ? : Mieux comprendre les causes des retournements de balance courante Les amples variations des soldes des paiements courants des pays peuvent avoir des effets perturbateurs, puisqu'elles tiennent souvent à de brusques interruptions des entrées de capitaux extérieurs et débouchent fréquemment sur des crises de change et bancaires. En conséquence, de nombreux travaux empiriques ont été réalisés sur la viabilité des soldes des paiements courants et les déterminants de leurs amples fluctuations. Nous apportons un nouvel éclairage sur cette question en procédant à un test de racine unitaire sur les ratios solde des paiements courants/PIB d'un vaste ensemble d'économies parvenues à maturité et émergentes, à partir d'une méthodologie tenant compte des ruptures structurelles dans les niveaux et les tendances des séries statistiques considérées. Nous établissons ensuite une chronologie des retournements de balance courante concordant avec la viabilité des positions extérieures, et nous l'utilisons pour estimer les facteurs qui expliquent la probabilité et l'ampleur de ces retournements à l'aide d'un modèle de sélection probit ordonné au premier stade. Nous parvenons à la conclusion que la plupart des facteurs qui expliquent la probabilité des retournements, telles que les tendances dans les flux de capitaux, dans le solde budgétaire et dans les positions extérieures, influent également sur leur ampleur. On relève toutefois quelques exceptions. Ainsi, l'orientation de la politique monétaire et l'ampleur des déséquilibres externes avant un retournement semblent être de meilleures variables explicatives de la probabilité des retournements que de leur ampleur.
