Complexity in large U.S. banks
While both size and complexity are important for the largest U.S. bank holding companies (BHCs), specific types of complexity and their patterns across banks are not well understood. We introduce a range of measures of organizational, business, and geographic complexity. Comparing 2007 with 2017, we show that large U.S. BHCs remain very complex, with some declines along organizational and geographical complexity dimensions. The numbers of legal entities within some large BHCs have fallen. By contrast, the multiple industries spanned by legal entities within the BHCs have shifted more than ...

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 ...

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 ...

U.S. Banks and Global Liquidity
We characterize how U.S. global systemically important banks (GSIBs) supply short-term dollar liquidity in repo and foreign exchange swap markets in the post-Global Financial Crisis regulatory environment and serve as the "lenders-of-second-to-last-resort". Using daily supervisory bank balance sheet information, we find that U.S. GSIBs modestly increase their dollar liquidity provision in response to dollar funding shortages, particularly at period-ends, when the U.S. Treasury General Account balance increases, and during the balance sheet taper of the Federal Reserve. The increase in the ...

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 ...

Did Too-Big-To-Fail Reforms Work Globally?
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 fail, the government would likely bail it out. Following the global financial crisis (GFC) of 2008, the G20 countries agreed on a set of reforms to eliminate the perception of TBTF, as part of a broader package to enhance financial stability. In June 2020, the Financial Stability Board (FSB), a sixty-eight-member international advisory body set up in 2009, published the results of a year-long evaluation of the ...

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 ...

Will Capital Flows through Global Banks Support Economic Recovery?
While policymakers around the world have aggressively and swiftly reacted to the common negative economic shock from COVID-19, the timing and forms of policy responses in the economic recovery stage may be more geographically differentiated. The range in policy responses, along with variations in the financial health of banks, likely will affect the flow of international credit through global banks. In this post, we ask whether, based on historical precedent, global banks are likely to provide additional support to the economic recovery in the locations they serve.

Follow That Money! How Global Banks Manage Liquidity Globally
Banks increasingly move money around the world. Over the last thirty years, gross international claims of banks from all countries have grown ten-fold, reaching a peak of about $25 trillion in 2007 (see chart below). Such global banking flows have been much in the news recently, sometimes depicted as a key culprit of the transmission around the globe of the shocks following the bankruptcy of Lehman Brothers, and more recently the European sovereign debt crisis. The discourse in the regulatory arena seems to share this sentiment, with a bias towards curbing some of the global banking activity ...
