Will the same causes produce the same effects? In other words, will the outbreak of war in Iran and the associated surge in oil prices (+44% to date) and gas prices (+64%) lead to an inflationary shock comparable to that of 2022? Will their negative effects on growth be the same as those of the war in Ukraine and the ensuing energy shock (a rise in oil prices of around 30% between 23 February and its peak in early June 2022, and a rise in gas prices of around 210% between 23 February and the peak in late August 2022)? The risk cannot be ruled out. Indeed, there are similarities and numerous uncertainties.
