Monetary Policy in a Developing Country
The transmission of monetary policy to credit aggregates and the real economy can be impaired by weaknesses in the contracting environment, shallow financial markets, and a concentrated banking system. We empirically assess the bank lending channel in Uganda during 2010–2014 using a supervisory dataset of loan applications and granted loans. Our analysis focuses on a short period during which the policy rate rose by 1,000 basis points and then came down by 1,200 basis points. We find that an increase in interest rates reduces the supply of bank credit both on the extensive and intensive margins, and there is significant pass-through to retail lending rates. We document a strong bank balance sheet channel, as the lending behavior of banks with high capital and liquidity is different from that of banks with low capital and liquidity. Finally, we show the impact of monetary policy on real activity across districts depends on banking sector conditions. Overall, our results indicate significant real effects of the bank lending channel in developing countries.
Bank Lending in the Knowledge Economy
We study bank portfolio allocations during the transition of the real sector to a knowledge economy in which firms use less tangible capital and invest more in intangible assets. We show that, as firms shift toward intangible assets that have lower collateral values, banks reallocate their portfolios away from commercial loans toward other assets, primarily residential real estate loans and liquid assets. This effect is more pronounced for large and less well capitalized banks and is robust to controlling for real estate loan demand. Our results suggest that increased firm investment in intangible assets can explain up to 20% of bank portfolio reallocation from commercial to residential lending over the last four decades.
Negative Monetary Policy Rates and Portfolio Rebalancing: Evidence from Credit Register Data
We study negative interest rate policy (NIRP) exploiting ECB's NIRP introduction and administrative data from Italy, severely hit by the Eurozone crisis. NIRP has expansionary effects on credit supply-- -and hence the real economy---through a portfolio rebalancing channel. NIRP affects banks with higher ex-ante net short-term interbank positions or, more broadly, more liquid balance-sheets, not with higher retail deposits. NIRP-affected banks rebalance their portfolios from liquid assets to credit—especially to riskier and smaller firms—and cut loan rates, inducing sizable real effects. By shifting the entire yield curve downwards, NIRP differs from rate cuts just above the ZLB.
Balance Sheet Strength and Bank Lending During the Global Financial Crisis
We examine the role of bank balance sheet strength in the transmission of financial sector shocks to the real economy. Using data from the syndicated loan market, we exploit variation in banks’ reliance on wholesale funding and their structural liquidity positions in 2007Q2 to estimate the impact of exposure to market freezes during 2007–08 on the supply of bank credit. We find that banks with strong balance sheets were better able to maintain lending during the crisis. In particular, banks that were ex-ante more dependent on market funding and had lower structural liquidity reduced the supply of credit more than other banks. However, higher and better-quality capital mitigated this effect. Our results suggest that strong bank balance sheets are key for the recovery of credit following crises, and provide support for regulatory proposals under the Basel III framework.
Crisis Transmission in the Global Banking Network
We study the transmission of financial sector shocks across borders through international bank connections. For this purpose, we use data on long-term interbank loans among more than 6,000 banks during 1997-2012 to construct a yearly global network of interbank exposures. We estimate the effect of direct (first-degree) and indirect (second-degree) exposures to countries experiencing systemic banking crises on bank profitability and loan supply. We find that direct exposures to crisis countries squeeze banks' profit margins, thereby reducing their returns. Indirect exposures to crisis countries enhance this effect, while indirect exposures to non-crisis countries mitigate it. Furthermore, crisis exposures have real effects in that they reduce banks' supply of domestic and cross-border loans. Our results, based on a large global sample, support the notion that interconnected financial systems facilitate shock transmission.
Business Cycle Fluctuations, Large Shocks, and Development Aid
We examine the cyclical properties of development aid using bilateral data for 22 donors and over 100 recipients during 1970?2005. We find that bilateral aid flows are on average procyclical with respect to business cycles in donor and recipient countries. However, they become countercyclical when recipient countries face large adverse shocks to the terms-of-trade or growth collapses-thus playing an important cushioning role. Aid outlays contract sharply during severe donor economic downturns; this effect is magnified by higher public debt levels. Additionally, bilateral aid flows are higher in the presence of IMF programs and are more countercyclical for recipient countries with stronger institutions.
A network analysis of global banking
In this paper we explore the properties of the global banking network using cross-border bank lending data for 184 countries over 1978-2009. Specifically, we analyze financial interconnectedness using network metrics of centrality, connectivity, and clustering. We document a relatively unstable global banking network, with structural breaks in network indicators identifying several waves of capital flows. Interconnectedness rankings, especially for borrowers, are relatively volatile over the period. Connectivity tends to fall during and after systemic banking crises and sovereign debt crises. The 2008-09 global financial crisis stands out as an unusually large perturbation to the cross-border banking network.
Financial Crises and the Composition of Cross-Border Lending
We examine the composition and drivers of cross-border bank lending between 1995 and 2012, distinguishing between syndicated and non-syndicated loans. We show that on-balance sheet syndicated loan exposures account for almost one third of total cross-border loan exposures during this period. Furthermore, syndicated loan exposures increased during the global financial crisis due to large drawdowns on credit lines extended before the crisis. Our empirical analysis of the drivers of cross-border loan exposures in a large bilateral dataset shows three main results. First, banks with lower levels of capital favor syndicated over other kinds of cross-border loans. Second, borrower country characteristics such as level of development, economic size, and capital account openness, are less important in driving syndicated than non-syndicated loan activity, suggesting a diversification motive for syndication. Third, information asymmetries between lender and borrower countries, which are important both in normal and crisis times, became more binding for both types of cross-border lending activity during the recent crisis.
Financial Inclusion Under the Microscope
We examine the impact of a large-scale microcredit expansion program on access to finance and the transition of first-time borrowers from microfinance institutions to the formal banking sector. Using administrative micro-data covering the universe of loans to individuals from a developing country, we show that the program significantly increased access to credit, particularly in less developed areas. This effect is driven by the newly set-up credit cooperatives (U-SACCOs), which grant loans to previously unbanked individuals. About 10\% of first-time U-SACCO borrowers that need a second loan switch to the formal banking sector, with commercial banks cream-skimming less risky borrowers from U-SACCOs and granting them larger, cheaper, and longer-term loans. These borrowers are not riskier than similar individuals already in the formal banking sector and only initially receive smaller loans. Our results suggest that the microfinance sector, together with a well functioning credit reference bureau, help mitigate information frictions in credit markets.
Household Credit, Global Financial Cycle, and Macroprudential Policies
We analyze the effects of macroprudential policies on local bank credit cycles and interactions with international financial conditions. For identification, we exploit the comprehensive credit register containing all bank loans to individuals in Romania, a small open economy subject to external shocks, and the period 2004-2012, which covers a full boom-bust credit cycle when a wide range of macroprudential measures were deployed. Although household leverage is known to be a key driver of financial crises, to our knowledge this is the first paper that employs a household credit register to study leverage and macroprudential policies over a full economic cycle. Our results show that tighter ma...
