No Guarantees, No Trade: How Banks Affect Export Patterns
How relevant are financial instruments to manage risk in international trade for exporting? Employing a unique dataset of U.S. banks' trade finance claims by country, this paper estimates the effect of shocks to the supply of letters of credit on U.S. exports. We show that a one-standard deviation negative shock to a country's supply of letters of credit reduces U.S. exports to that country by 1.5 percentage points. This effect is stronger for smaller and poorer destinations. It more than doubles during crisis times, suggesting a non-negligible role for finance in explaining the Great Trade ...

Bank Complexity, Governance, and Risk
Bank holding companies (BHCs) can be complex organizations, conducting multiple lines of business through many distinct legal entities and across a range of geographies. While such complexity raises the costs of bank resolution when organizations fail, the effect of complexity on BHCs’ broader risk profiles is less well understood. Business, organizational, and geographic complexity can engender explicit trade-offs between the agency problems that increase risk and the diversification, liquidity management, and synergy improvements that reduce risk. The outcomes of such trade-offs may ...

Did Subsidies to Too-Big-To-Fail Banks Increase during the COVID-19 Pandemic?
Once a bank grows beyond a certain size or becomes too complex and interconnected, investors often perceive that it is “too big to fail” (TBTF), meaning that if the bank were to become distressed, the government would likely bail it out. In a recent post, I showed that the implicit funding subsidies to systemically important banks (SIBs) declined, on average, after a set of reforms for eliminating TBTF perceptions was implemented. In this post, I discuss whether these subsidies increased again during the COVID-19 pandemic and, if so, whether the increase accrued to large firms in all ...

A Neoclassical Model of the World Financial Cycle
Emerging markets face large and persistent fluctuations in sovereign spreads. To what extent are these fluctuations driven by local shocks versus financial conditions in advanced economies? To answer this question, we develop a neoclassical business cycle model of a world economy with an advanced country, the North, and many emerging market economies, the South. Northern households invest in domestic stocks, domestic defaultable bonds, and international sovereign debt. Over the 2008-2016 period, the global cycle phase, the North accounts for 68% of Southern spreads' fluctuations. Over the ...

What are the consequences of global banking for the international transmission of shocks?: a quantitative analysis
The global financial crisis of 2008 was followed by a wave of regulatory reforms that affected large banks, especially those with a global presence. These reforms were reactive to the crisis. In this paper we propose a structural model of global banking that can be used proactively to perform counterfactual analysis on the effects of alternative regulatory policies. The structure of the model mimics the US regulatory framework and highlights the organizational choices that banks face when entering a foreign market: branching versus subsidiarization. When calibrated to match moments from a ...

No guarantees, no trade: how banks affect export patterns
This study provides evidence that shocks to the supply of trade finance have a causal effect on U.S. exports. The identification strategy exploits variation in the importance of banks as providers of letters of credit across countries. The larger a U.S. bank?s share of the trade finance market in a country, the larger should be the effect on exports to that country if the bank changes its supply of letters of credit. We find that a shock of one standard deviation to a country?s supply of letters of credit increases export growth, on average, by 1.5 percentage points. The effect is larger for ...

How Do Liquidity Conditions Affect U.S. Bank Lending?
The recent financial crisis underscored the importance of understanding how liquidity conditions for banks (or other financial institutions) influence the banks’ lending to domestic and foreign customers. Our recent research examines the domestic and international lending responses to liquidity risks across different types of large U.S. banks before, during, and after the global financial crisis. The analysis compares large global U.S. banks—that is, those that have offices in foreign countries and are able to move liquidity from affiliates across borders—with large domestic U.S. banks, ...

Global Banks and Their Internal Capital Markets during the Crisis
As financial markets have become increasingly globalized, banks have developed growing networks of branches and subsidiaries in foreign countries. This expansion of banking across borders is changing the way banks manage their balance sheets, and the ways home markets and foreign markets respond to disturbances to financial markets. Based on our recent research, this post shows how global banks used their foreign affiliates for accessing scarce dollars during the financial crisis—a liquidity strategy that helped transmit shocks internationally while reducing some of the consequences in the ...

Monetary policy and global banking
Global banks use their global balance sheets to respond to local monetary policy. However, sources and uses of funds are often denominated in different currencies. This leads to a foreign exchange (FX) exposure that banks need to hedge. If cross?currency flows are large, the hedging cost increases, diminishing the return on lending in foreign currency. We show that, in response to domestic monetary policy easing, global banks increase their foreign reserves in currency areas with the highest interest rate, while decreasing lending in these markets. We also find an increase in FX hedging ...

Organizational complexity and balance sheet management in global banks
Banks have progressively evolved from being standalone institutions to being subsidiaries of increasingly complex financial conglomerates. We conjecture and provide evidence that the organizational complexity of the family of a bank is a fundamental driver of the business model of the bank itself, as reflected in the management of the bank?s own balance sheet. Using micro-data on global banks with branch operations in the United States, we show that branches of conglomerates in more complex families have a markedly lower lending sensitivity to funding shocks. The balance sheet management ...
