Knowledge that Transforms

We empirically study how banks’ conversions from mutual to stock ownership affect depositor welfare. Using U.S. data and a discrete choice model of deposit account demand, we show that when a bank is mutual, depositors are less sensitive to price, and each unit of cash and liquidity services is valued more positively. We then examine how mutual-to-stock conversions affect deposit account characteristics and combine these changes with our demand estimates to assess conversions’ impact on depositor welfare. Our estimates indicate that conversions increase depositor welfare, challenging the premise that mutual banks operate for the benefit of their members.

We examine global bank lending during geopolitical conflicts. Exploiting Russia’s 2014 countersanctions on the European agricultural industry, we analyze global banks’ syndicated lending to affected firms. We document a significant increase in credit supply to the sanctioned industry, accompanied by a significant increase in the shares of loans with lower spreads and longer maturities. The expansion of credit is not driven by incumbent banks alone. Instead, banks with little prior exposure to agriculture—particularly foreign banks headquartered in alternative export destinations where European firms are likely to redirect trade—account for a considerable proportion of the increased lending. This finding suggests banks actively rebalance their loan portfolio and strategic positioning in response to shifting trade flows. Our findings highlight the role of banks as intermediaries that adjust credit allocation across sectors during geopolitical disruptions, thereby cushioning targeted industries and facilitating their transition toward new markets.
