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.

We investigate the transmission of monetary policy through the supply chains with US data on corporate linkages. Our analysis uncovers three key insights. First, contractionary monetary conditions lead to production disruptions in financially constrained rms. Second, these disruptions extend to the suppliers and customers of such firms. Third, disruptions intensify when financially constrained firms purchase or sell specialized goods. These findings suggest that monetary tightening creates bottlenecks in supply chains, forcing firms to curtail production when they cannot substitute their constrained business partners. \Monetary policy bottlenecks" amplify the impact ofmonetary policy beyond the standard balance sheet channel of transmission.

We document a significant role for nonbanks in financing the green transition following the Paris Agreement, primarily through lending partnerships with banks. Using textual analysis to identify green loans, we show that nonbanks participate in a greater number of green syndicated loans and commit larger amounts in response to corporate demand for green financing. Such nonbank investment in green loans is associated with more favorable loan terms and is consistent with a nonbank-led expansion in credit supply rather than bank-driven risk offloading. Nonbank investment is highly sensitive to policy signals, suggesting that regulatory transition risk is a key driver. Overall, our findings show the potential for nonbanks to support the transition but only under credible political commitment to climate goals.
