Banks’ Foreign Currency Exposure and the Real Effects of Exchange Rate Shocks (R&R at the Review of Financial Studies)
Abstract: In contrast to standard theory, recent empirical evidence shows that currency depreciations are not always expansionary. I show that a bank lending channel of exchange rates can explain this disconnect. I provide causal evidence on the importance of this channel using a large and unanticipated currency appreciation shock from Switzerland. I construct a novel dataset on foreign currency exposure of Swiss banks and bank-firm relationships, and show that the currency appreciation shock enabled banks with net foreign currency liability exposure to increase lending, allowing firms to increase investment. The bank lending channel thus partially offsets the negative effect of currency appreciation on exports, explaining the muted response of aggregate output to the shock. I also construct a new historical database on banks’ foreign currency exposure for a sample of 43 countries and provide evidence on the general importance of this channel across historical global currency depreciations.
Inflation and Disintermediation (with Matthew Baron) R&R at the Journal of Financial Economics
Abstract: We test a bank credit channel through which unexpected increases in inflation lead to short-run macroeconomic fluctuations. For identification, we study an unexpected U.S. inflation increase in early 1977 and exploit differences in state-level reserve requirements for Federal Reserve nonmember banks, which create differences in banks’ inflation exposures. More exposed banks cut lending, reducing local house prices and construction employment. We provide evidence for potential mechanisms, including a bank net wealth and a loan misallocation channel. Our results suggest that an important consequence of inflation is its impairment of the banking sector.
Relative Pricing of Private and Public Debt: The Role of Money Creation Channel (with Jan Bena and Joyce Xuejing Guan)
We examine how the money creation function of banks affects the relative cost of firm financing in the bank loan vs public bond market – the loan-bond spread. Using a sample of loans and bonds issued by the same firm with the same maturity and at the same time, we show that the loan-bond spread is lower for firms impacted by information cost shocks. We call this decline in the relative cost of bank credit induced by firm information cost shock the opacity discount and argue that it is consistent with the “money creation” hypothesis in the theory of financial intermediation according to which banks need to keep information about their assets secret to produce private money.
Bank Regulation and Supervision: A Symbiotic Relationship (with Tirupam Goel)
Abstract: Supervisory assessments such as stress-tests gauge banks’ riskiness and allow regulators to impose bank-specific capital regulation. This can improve welfare. Yet, regulation based on noisy supervision can decrease welfare by mis-classifying banks, distorting incentives, and creating riskier banks. Regulation should not be bank-specific in such cases. When bank defaults are costlier, supervision should lower the probability that riskier banks go undetected, i.e., reduce false-negatives even if this leads to more false-positives. When the supervisor can conduct a more comprehensive but costlier assessment that optimally reduces both false-positive and false-negative rates, the regulator should make capital requirements more bank specific.
Lending by Servicing: How Shadow Banks Dampen Monetary Policy Transmission (with Malin Hu and Keling Zheng)
Abstract: Despite the growing share of shadow banks in the U.S. mortgage market, the interaction between their origination and servicing business and its implications for monetary policy transmission are not well understood. We propose and test a novel channel of monetary policy transmission through shadow banks in the mortgage market, the mortgage servicing channel. We document that, during periods of monetary tightening, mortgage servicing rights (MSRs) act as a hedge and weaken the transmission of monetary policy to mortgage lending by shadow banks. Higher interest rates reduce prepayment risk, increasing the collateral value of MSRs and allowing shadow banks to receive more funding to originate mortgages. This effect is stronger for shadow banks with ex ante low liquidity and capital ratios and riskier portfolios.
The Determinants of China’s International Portfolio Equity Allocations (with Grace Weishi Gu and Eswar Prasad), IMF Economic Review, May 2020 (previously circulated as China’s Impact on Global Financial Markets, NBER Working paper No. 26311)
Abstract: We analyze shifts in the structure of China’s capital outflows over the past decade. The composition of gross outflows has shifted from accumulation of foreign exchange reserves by the central bank to nonofficial outflows. Unlocking the enormous pool of domestic savings could have a significant impact on global financial markets as China continues to open up its capital account and as domestic investors look abroad for returns and diversification. We analyze in detail the allocation patterns of Chinese institutional investors (IIs), which constitute the main channel for foreign portfolio investment outflows. We find that, relative to benchmarks based on market capitalization, Chinese IIs underweight developed countries and high-tech sectors in their international portfolio allocations but overinvest in high-tech stocks in developed countries. To further examine Chinese IIs’ joint decisions on destination country-sector pairs, we construct continuous measures of revealed relative comparative advantage and disadvantage in a sector for a country based on trade patterns. We find that, in their foreign portfolio allocations, Chinese IIs overweight sectors in which China has a comparative disadvantage. Moreover, Chinese IIs concentrate such investments in countries that have higher relative comparative advantage in those sectors. Diversification and information advantages related to foreign imports to China seem to influence patterns of foreign portfolio allocations, while yield-seeking and learning motives do not.

Commodity Prices and Bank Lending (with Rupa Duttagupta and Andrea Presbitero), Economic Inquiry, August 2019
Abstract: We analyze the transmission of changes in commodity prices to bank lending in a large sample of developing countries. A bank-level analysis shows that a fall in commodity net export prices is associated with a reduction of bank lending, particularly for commodity exporters and during episodes of terms-of-trade decline. We complement this analysis with loan-level data from a credit register, which allows us to identify the effect of a commodity price shock on the supply of credit, controlling for unobserved factors that could drive borrowers’ credit demand. Results show that banks with relatively lower deposits and poor asset quality transmit the changes in commodity prices to lending more aggressively.
