The international transmission of bank capital requirements: Evidence from the UK

We use data on UK banks? minimum capital requirements to study the impact of changes to bank-specific capital requirements on cross-border bank loan supply from 1999Q1 to 2006Q4. By examining a sample in which each recipient country has multiple relationships with UK-resident banks, we are able to control for demand effects. We find a negative and statistically significant effect of changes to banks? capital requirements on cross-border lending: a 100 basis point increase in the requirement is associated with a reduction in the growth rate of cross-border credit of 5.5 percentage points. We also find that banks tend to favor their most important country relationships, so that the negative cross-border credit supply response in “core” countries is significantly less than in others. Banks tend to cut back cross-border credit to other banks (including foreign affiliates) more than to firms and households, consistent with shorter maturity, wholesale lending which is easier to roll off and may be associated with weaker borrowing relationships.     

FOREIGN EXCHANGE AND CROSS-BORDER VALUATION

Should a corporate financial manager analyze a cross-border investment proposal from the perspective of the foreign currency or the home currency? The conventional wisdom among economists is that it doesn't matter–the valuation of an asset should be the same in one currency as in another, given the spot FX rate. This assertion implies that it is irrelevant whether we analyze an overseas investment's NPV in the home currency or the foreign currency, as long as we use consistent cross-border conversions.
But what happens if managers' foreign exchange forecasts differ from the efficient markets forecast that is implicit in interest rates? In that case, as this article demonstrates through a series of examples, managers' FX forecasts can affect their investment, hedging, and financing decisions.     

Cross-border banking,bank market structures and market power: Theory and cross-country evidence

Patterns in cross-border banking have changed since the global financial crisis. This may affect domestic bank market structures and macroeconomic stability in the longer term. In this study, I theoretically and empirically analyze how different modes of cross-border banking impact bank concentration and market power. I use a two-country general equilibrium model with heterogeneous banks developed by DeBlas and Russ (2010a) to grasp the effect of cross-border lending and foreign direct investment in the banking sector on bank market structures. The model suggests that both cross-border lending and bank FDI mitigate concentration. Empirical evidence from a panel dataset of 18 OECD countries supports the theoretical predictions: higher volumes of bank FDI and of cross-border lending coincide with lower Herfindahl-indexes in bank credit markets.     

The international transmission of monetary policy

This paper presents the novel results from an internationally coordinated project by the International Banking Research Network (IBRN) on the cross-border transmission of conventional and unconventional monetary policy through banks. Teams from seventeen countries use confidential micro-banking data for the years 2000 through 2015 to explore the international transmission of monetary policies of the United States, euro area, Japan, and United Kingdom. Two other studies use international data with different degrees of granularity. International spillovers into lending to the private sector do occur, especially for US policies, and bank-specific heterogeneity influences the magnitudes of transmission. The effects are supportive of the international bank lending channel and the portfolio channel of monetary policy transmission. They also show that the frictions that banks face matter; in particular, foreign currency funding and hedging considerations can be a key source of heterogeneity. The forms of bank balance sheet heterogeneity that differentiate spillovers across banks are not uniform across countries. International spillovers into lending can be large for some banks, even while the average international spillovers of policies into nonbank lending generally are not large.     

Does Macro‐Prudential Regulation Leak? Evidence from a UK Policy Experiment

The regulation of bank capital as a means of smoothing the credit cycle is a central element of forthcoming macro‐prudential regimes internationally. For such regulation to be effective in controlling the aggregate supply of credit it must be the case that: (i) changes in capital requirements affect loan supply by regulated banks, and (ii) unregulated substitute sources of credit are unable to offset changes in credit supply by affected banks. This paper examines micro evidence—lacking to date—on both questions, using a unique data set. In the UK, regulators have imposed time‐varying, bank‐specific minimum capital requirements since Basel I. It is found that regulated banks (UK‐owned banks and resident foreign subsidiaries) reduce lending in response to tighter capital requirements. But unregulated banks (resident foreign branches) increase lending in response to tighter capital requirements on a relevant reference group of regulated banks. This “leakage” is substantial, amounting to about one‐third of the initial impulse from the regulatory change.     

Foreign banks in syndicated loan markets

Foreign banks play a prominent role in syndicated loan markets. In this paper we examine foreign banks’ motives in participating in cross-border deals in 25 European countries. We find that usual explanations of foreign banking activities can only account partly for the high rate of foreign involvement in syndicated loan markets. The usual argument is that foreign banks are at a disadvantage because they lack soft information and thus they tend to lend to more transparent firms compared to their domestic counterparts. We find that this relationship only holds in relatively small financial systems. We illustrate different motivations for the large amount of cross border lending in large developed markets. In these markets foreign banks tend to lend to especially risky borrowers and projects.

The spillovers,interactions, and (un)intended consequences of monetary and regulatory policies

Have bank regulatory policies and unconventional monetary policies—and any possible interactions—been a factor behind the recent “deglobalisation” in cross-border bank lending? To test this hypothesis, we use bank-level data from the UK—a country at the heart of the global financial system. Our results suggest that increases in microprudential capital requirements tend to reduce international bank lending and some forms of unconventional monetary policy can amplify this effect. Specifically, the UK׳s Funding for Lending Scheme (FLS) significantly amplified the effects of increased capital requirements on cross-border lending. Quantitative easing did not appear to have a similar effect and countries with stronger prudential capital regulations were partially insulated against the effects of these changes in UK policy. We find that this interaction between microprudential regulations and the FLS can explain roughly 30% of the contraction in aggregate UK cross-border bank lending between mid-2012 and end-2013, corresponding to around 10% of the global contraction in cross-border lending. This suggests that unconventional monetary policy designed to support domestic lending can have the unintended consequence of reducing foreign lending.     

Monetary Policy and Global Banking

When central banks adjust interest rates, the opportunity cost of lending in local currency changes, but—absent frictions—there is no spillover effect to lending in other currencies. However, when equity capital is limited, global banks must benchmark domestic and foreign lending opportunities. We show that, in equilibrium, the marginal return on foreign lending is affected by the interest rate differential, with lower domestic rates leading to an increase in local lending, at the expense of a reduction in foreign lending. We test our prediction in the context of changes in interest rates in six major currency areas.     

Foreign Banks in Transition Countries: To Whom Do They Lend and How Are They Financed?

We use focused interviews with managers of foreign parent banks and their affiliates in Central Europe and the Baltic States to analyze the small‐business lending and internal capital markets of multinational financial institutions. Our approach allows us to complement the standard empirical literature, which has difficulty in analyzing important issues such as lending technologies and capital allocation. We find that the acquisition of local banks by foreign banks has not led to a persistent bias in these banks' credit supply toward large multinational corporations. Instead, increased competition and the improvement of subsidiaries' lending technologies have led foreign banks to gradually expand into the SME and retail markets. Second, it is demonstrated that local bank affiliates are strongly influenced by the capital allocation and credit steering mechanisms of the parent bank.     

“When the cat's away the mice will play”: Does regulation at home affect bank risk-taking abroad?

This paper provides the first empirical evidence that bank regulation is associated with cross-border spillover effects through the lending activities of large multinational banks. We analyze business lending by 155 banks to 9,613 firms in 1,976 different localities across 16 countries. We find that lower barriers to entry, tighter restrictions on bank activities, and to a lesser degree higher minimum capital requirements in domestic markets are associated with lower bank lending standards abroad. The effects are stronger when banks are less efficiently supervised at home, and are observed to exist independently from the impact of host-country regulation.     

Withdrawal from Foreign Lending in the Financial Crisis by Parent Banks and Their Branches and Subsidiaries: Supply Versus Demand Effects

This study investigates the different channels through which internationally active banks can provide loans abroad. Using data on German banks from 2002 to 2010, we contrast determinants for cross-border lending by the parent bank with lending by affiliates located abroad. We show that lending by parent banks is based almost entirely on supply-side determinants, in particular on bank-specific factors. The more the loans are intermediated by banks’ affiliates located abroad, the more relevant become foreign countries’ demand and risk characteristics. This applies in particular when banks operate via locally focused affiliates - rather than regionally active hub affiliates - as well as when the affiliates have the status of branches as opposed to legally independent subsidiaries. In general, banks with a greater risk aversion withdraw more from foreign lending during the financial crisis, especially following the collapse of Lehman Brothers. However, at a Tier I capital ratio of around 11 %, a further increase in the ratio did not affect lending anymore.     

The effect of banking regulation on cross-border lending

Banking regulations often differ between countries: Some regulators require banks to document their evaluation of firms’ creditworthiness, which determines the banks’ choice of lending technology. In a theoretical model, we study how differences in regulation influence competition between domestic and foreign banks and analyze the effect of regulatory harmonization on cross-border lending. We predict that lending rates are lower and access to credit is easier for firms in a border region if the national regulations differ. Using unique bank- and firm-level data from Germany, we show that firms in a border region have better access to credit if regulation differs.     

Network effects in currency internationalisation: Insights from BIS triennial surveys and implications for the renminbi

The dominance of the US dollar in foreign exchange (FX) markets appears to reflect very strong network effects in the use of international currencies. What we observe today is the result of a slow-moving process that has witnessed a switch from the dominance of the pound sterling to the US dollar, perhaps during the interwar period in the early part of the 20th century. This paper presents a discrete choice model of FX trading that explicitly allows for this type of critical transitions in order to understand the dynamics of currency turnover in FX markets. We estimate the model using the Bank for International Settlements' data from triennial surveys of FX markets and also examine the factors that could potentially shift the dynamic path and lead to an earlier critical transition. We then discuss the implications for the renminbi, a budding international currency. If the renminbi were to become a dominant international currency, it would require China to attain a much higher level of financial development and openness. It is important to note that our model does not address the possibility of a gradual weakening of the network effects in FX markets due to, for example, the advancement of trading technologies, which would allow the co-existence of a few equally dominant major currencies.     

Can central banks be heard over the sound of gunfire?

In this study, we examined the effectiveness of central bank communications during times of significant adverse shocks. Specifically, we examined how the National Bank of Ukraine (NBU) regulated foreign exchange (FX) markets during the Russo-Ukrainian War in 2022. Data collected from both the black and authorized FX markets suggested that the content of the NBU's announcements significantly impacted FX market agents. Announcements aimed at maintaining a fixed (floating) FX rate prompted an increase (decrease) in the black market premium in cash transactions. Moreover, the NBU's announcements influenced the sale side of foreign currency more than any other aspect, an area where the black market FX traders held near monopolistic power.     

Foreign Bank Behavior during Financial Crises

This paper studies whether lending by foreign banks is affected by financial crises. We pair a bank‐level data set of foreign ownership with information on banking crises and examine whether the credit supply of majority foreign‐owned banks that underwent home‐country crises differ systematically from those of other foreign banks. In contrast to the literature, our broad global coverage allows us to exploit variations between foreign banks; this enables us to identify an average treatment effect directly attributable to crises. Our baseline results show that banks exposed to home‐country crises between 2007–08 exhibit changes in lending patterns that are lower by between 13% and 42% than their noncrisis counterparts. This finding is robust to potential alternative explanations, and also holds, though less strongly, for the 1997/98 Asian crisis.     

The Effects of Dynamic Changes in Bank Competition on the Supply of Small Business Credit

We study the effects of structural changes in banking markets on the supply of credit to small businesses. Specifically, we examine whether bank mergers and acquisitions (M & As) and entry have ``external' effects on small business loans by other banks in the same local markets. The results suggest modest positive external effects from these dynamic changes in competition, except that large banks may reduce small business lending in reaction to entry. We confirm bank size and age as important determinants of this lending, and show that the measured age effect does not appear to be driven by local market M & A activity.     

Intra- and inter-regional portfolio diversification strategies under regional market integration: Evidence from U.S. global banks

This study empirically assesses whether being a part of any specific region affects global banks' decisions on capital allocation across 20 developed and 44 emerging markets by using data on U.S. banks in the period from 2006 to 2015. We find that both the intra-bank lending of a parent bank to its affiliates abroad and the local lending of foreign affiliates decrease as internal lending to neighboring countries within a region increases. This finding provides evidence of the negative spillover or contagion effects from regional allocations on the capital allocation of global banks to individual economies. Our findings reflect that financial markets are integrated within the region, which suggests no intra-regional diversification benefits to the United States or to other global investors. Moreover, parent banks' intra-bank lending translates into foreign affiliates' local lending in the host country. A policy implication is that countries in the same region should strengthen coordinated efforts to ensure free intra-regional capital mobility and diversify country-specific risk. The findings of this study can help enhance our understanding of the relationships between financial markets interconnectedness and global banks' portfolio management strategies.

Does FOMC news increase global FX trading?

Does global currency volume increase on Federal Open Market Committee (FOMC) days? To test hypotheses of abnormal currency volume on FOMC days, a new data set from the Continuous Linked Settlement (CLS) Bank is used. The CLS measure captures more than half of the global trading volume in foreign exchange (FX) markets. The evidence shows that FX trading volume increases about 5% in the spot and the spot-next market following FOMC deliberations. The novelty of this result is that the aggregated CLS data controls for responses in various derivatives markets: a feature that existing studies based on intradaily data for specific trading platforms do not consider.
