We assess whether, complementary to trade and financial linkages, banking sector fragility helps explain the transmission of currency crises. We attempt to strike a balance between the precision of measurement of banking sector fragility on the one hand and its consistent measurement across various crisis episodes on the other. We find that while the role of trade and financial linkages is robust over time, the independent role of banking sector fragility is rather weak and unstable across crisis episodes. Consequently it is difficult to extrapolate observed banking fragility transmission channels from one crisis to another. As a corollary we cannot conclude that during future crisis episodes economies characterized by fragile banking sectors are more prone to crisis transmission.
