This article investigates the potential of nonlinear causal relationships between world oil prices and stock markets in Middle East and North Africa (MENA) countries during a black swan period that is characterized by rarity and devastating impacts. Our study is carried out using the daily data for 11 MENA countries over the period from 2 July 2007 to 27 August 2012. By using the nonlinear and asymmetric causality test of Kyrtsou and Labys (2006), we mainly find that: (i) the oil prices and MENA stock markets interact in a nonlinear manner; (ii) the signs of changes in the causing variables are important for detecting the true causality links between the variables and (iii) the nonlinear causality is more pronounced in the case of the Brent than West Texas Intermediate oil prices.
