This paper investigates the convergence in real gross domestic product growth focusing on the impact of financial crises (i.e. banking crises, currency crises and debt crises) and nominal exchange-rate regimes (i.e. fixed, intermediate and flexible) on convergence. To that end, we compute four convergence indicators (<italic>σ</italic>-convergence, <italic>γ</italic>-convergence, absolute <italic>β</italic>-convergence and conditional <italic>β</italic>-convergence) for 163 countries classified into four income groups during the period 1970--2011. The results suggest that (i) there is evidence in favour of <italic>σ</italic>-convergence and <italic>γ</italic>-convergence only for high-income countries; (ii) absolute and conditional <italic>β</italic>-convergence are present in each of the four income groups of the countries under study; (iii) exchange-rate regimes seem to play some role in upper-middle and lower-middle-income countries; and (iv) financial crises have a negative and significant impact on GDP growth independently of the income level of the countries.
