Banks of a Feather: The Informational Advantage of Being Alike

Research question and motivation: Can banks effectively monitor their peers under asymmetric information? Effective peer monitoring matters for functioning interbank markets and, by implication, financial markets and the transmission of monetary policy. If banks monitor effectively, central banks can stay in a “night-watchman” role (Goodfriend and King 1988); if they systematically fail to identify solvent counterparties, central banks should be more active (Freixas and Jorge 2008). The paper argues that PORTFOLIO SIMILARITY between two banks is the key to their reciprocal monitoring ability: a lender uses private information about its own loan portfolio to assess the quality of a peer’s portfolio, so it is better informed the more similar the two exposures.

Research question and motivation. The paper asks how exchange rate movements affect the real economy and what role the banking system’s foreign-asset exposure plays in transmitting exchange rate shocks. The motivation is concrete: with the Federal Reserve’s “tapering” of quantitative easing, the euro lost slightly more than 20% against the US dollar between 2014:Q2 and 2015:Q1, a sharp, persistent and largely unanticipated move. Standard open-economy models predict depreciations raise output via the trade balance, but recent work questions this classical trade channel and emphasizes firm/bank balance-sheet channels. The paper complements this by examining how a depreciation reshapes the composition of bank credit and, ultimately, regional output—working through banks’ net foreign asset (NFA) exposure rather than trade.
