Points clés :

• We show the price impact of biofuels on the current account for agricultural commodity-producing and exporting countries depends on the level reached by the price of oil.
• Positive shocks in the price of biofuels lead to a current-account appreciation for agricultural commodity exporters and producers only when the price of oil is below a certain threshold.
• When the price of oil exceeds this threshold, fluctuations in the price of biofuels no longer affect the current account.
• A rise in the price of oil exerts a negative effect on the trade balance of commodity exporters which are also oil importers, dampening the biofuel price impact on the current-account position.

 Résumé :
Many developed countries promote the use of biofuels for environmental concerns, leading to a rise in the price of agricultural commodities utilized in their production. Such environmental policies have major effects on the economy of emerging and developing countries whose activity is highly dependent on agricultural commodities involved in biofuel production. This paper tackles this issue by examining the price impact of biofuels on the current account for a panel of 16 developing and emerging countries, and the potential nonlinear effect exerted by the price of oil on this relationship. Relying on the estimation of panel smooth-transition regression models, we show that positive shocks in the price of biofuels lead to a current-account appreciation for agricultural commodity exporters and producers only when the price of oil is below a certain threshold. When the price of oil exceeds this threshold, fluctuations in the price of biofuels no longer affect the current account. These findings illustrate that a rise in the price of oil exerts a negative effect on the trade balance of commodity exporters which are also oil importers, dampening the biofuel price impact on the current-account position.
