Asymmetric quantile analysis of the Swedish mortgage price discovery process

Based on Swedish banking data we discover robust and significantly positive Asymmetric Price Transmission (APT) effects over all analysed regression quantiles of our mortgage interest rates, with even larger positive APT for the higher percentiles. The analysis was enabled through unique access to a Swedish bank's (SEB) own records of their true borrowing costs. Our central contribution is that there is a higher propensity for the bank to rapidly increase its mortgage interest rates for customers following an increase in its borrowing costs, compared with the propensity for the bank to decrease its customers’ mortgage rates subsequent to a corresponding borrowing cost decrease.     

The efficiency of the Scandinavian banking sector – a wavelet quantile regression analysis

In this article, the Scandinavian housing financing market is analysed in order to determine whether the interest rate price-discovery processes of Denmark, Norway and Sweden are efficient. Based on wavelet quantile regression analysis, we find systematic positive asymmetric price transmission (APT) inefficiencies. We conclude that there is a very high propensity for mortgage lenders to directly increase its customers’ mortgage interest rates subsequently to an increase in its borrowing costs. However, after a corresponding borrowing cost decrease, the same mortgage lenders are very slow to decrease its customers’ mortgage rates. These positive coefficients for so-called APT effects are found in all Scandinavian countries, even if the coefficients for Norway were not statistically significant. Wavelet quantile regression analysis, with a focus on the relevant higher percentiles, is easily motivated since the mortgage rates are adjusted very infrequently. Moreover, wavelet decomposition allows a robust analysis at different time frequency scales, while simultaneously controlling for nonstationary trends, autocorrelation and structural breaks. Except for the still positive but yet insignificant and inconclusive coefficients for Norway, the result is very clear-cut. Regardless of which wavelet scaling decomposition or quantile coefficient that is studied – positive APT effects are clearly identified and confirmed on the Scandinavian mortgage market.     

The Price Impact of Lending Relationships

This study analyzes the impact of bank relationships on a firm's borrowing costs. We find that a firm's borrowing costs decrease with relationship strength, proxied by the share of bank debt provided by the lender. Borrowing costs, however, rise with relationship length. While the increase over time is weak on average, bank‐dependent borrowers face a substantial premium after several relationship years. Switching the lender initially leads to only a small price discount on average. However, the discount is considerable for borrowers that switch and had a strong relationship with their previous lender. Our results suggest that close lending relationships lead to benefits for the firm, but may also imply hold‐up costs in the long term.     

Household’s optimal mortgage and unsecured loan default decision

How do households make optimal borrowing and default decisions when they have the option to borrow in multiple ways? In this paper, I analyze households’ optimal mortgage and unsecured loan borrowing and default decisions in the context of the recent recession. I model households as able to default on mortgage debt to walk away from capital losses, at the price of foreclosure. However, a household can also default on unsecured debt to maintain its home, in exchange for a longer exclusion from credit markets following default. Depending on the costs of each alternative, financially constrained households exhibit heterogeneity in optimal default decisions.Next, I analyze how mortgage loan modification policies, after a sudden drop in house prices, affect household choices in the mortgage and unsecured loan markets. The quantitative exercise shows that the government-driven mortgage modification program, initiated in 2009, reduces the mortgage default rate by 0.27% points. However, this increases the unsecured loan charge-off rate by 0.66% points.     

Beliefs, Bailouts and Spread of Bank Panics

This article highlights the spread of bank panics across countries, as the public reassesses governments' propensity to bailouts. Policymakers decide whether to save collapsing banking systems by weighing social costs of crises against the costs associated with raising taxes to finance rescue packages. Policymakers know those social costs of bank liquidation whereas the public does not. In this setup, financial crises may result from the public's self‐fulfilling prophecies about equilibrium outcomes, as lenders' expectations impinge on the taxation cost of bailouts. It follows that a banking crisis in a country leads creditors to reexamine policymakers' willingness to bailouts in other countries, which eventually makes their banks more vulnerable to self‐confirming depositors' runs.     

Scarce collateral and bank reserves

If collateral for bank loans is scarce and, if as a result, access to secured loans is restricted, the allocation of resources is inefficient. In anticipation of future borrowing constraints, individuals over-invest in collateralized types of capital, and consume and invest inefficiently low levels while they are borrowing constrained. The dual counterpart of this misallocation of resources is inefficiently low interest rates. In this situation, bank reserves play a positive welfare role by adding liquidity to the economy and by increasing not only bank lending rates, but also, paradoxically, bank deposit rates. As a result, in economies with scarce collateral the optimal reserves–requirement ratio is positive.     

Prices versus quantities versus bankable quantities

Quantity-based regulation with banking allows regulated firms to shift obligations across time in response to periods of unexpectedly high or low marginal costs. Despite its wide prevalence in existing and proposed emission trading programs, banking has received limited attention in past welfare analyses of policy choice under uncertainty. We address this gap with a model of banking behavior that captures two key constraints: uncertainty about the future from the firm's perspective and a limit on negative bank values (e.g. borrowing). We show conditions where banking provisions reduce price volatility and lower expected costs compared to quantity policies without banking. For plausible parameter values related to U.S. climate change policy, we find that bankable quantities produce behavior quite similar to price policies for about two decades and, during this period, improve welfare by about a $1 billion per year over fixed quantities.     

Creditor concentration: An empirical investigation

Most of the literature on multiple banking assumes equal financing shares. However, unequal, asymmetric or concentrated bank borrowing is widespread, and creditor concentration is only weakly correlated with the number of bank relationships. This paper therefore investigates the determinants of creditor concentration for German firms using a comprehensive firm-bank level dataset for the time period between 1993 and 2003. We document that corporate borrowing from banks is very often concentrated, even for the largest firms in our sample. Leveraged firms and firms with more redeployable assets concentrate their borrowing from banks, as are firms dealing with a relationship lender that is profitable, that has lower monitoring costs, or that operates in a concentrated regional lending market.     

Capital controls and welfare with cross-border bank capital flows

This performance of time-varying capital controls on cross-border bank borrowing is studied in an open-economy, dynamic stochastic general equilibrium model with financial frictions and imperfect capital mobility. The model is parameterized for a middle-income country and replicates the stylized facts associated with a drop in world interest rates—capital inflows, real appreciation, credit boom, asset price pressures, and output expansion. A capital controls rule, which is fundamentally macroprudential in nature, is defined in terms of changes in bank foreign borrowing. The welfare-maximizing rule is established numerically and compared to the Ramsey policy. The analysis is then extended to solve jointly for optimal countercyclical reserve requirements and capital controls rules. The results show that the implementation of a countercyclical credit-based reserve requirement rule induces less reliance on capital controls. Thus, these two instruments are partial substitutes in maximizing welfare.     

Assessing the macroeconomic impact of alternative macroprudential policies

This article assesses effects on the wider economy and overall costs and benefits of two alternative macroprudential policies - loan-to-value ratios on mortgage lending and variable bank capital adequacy targets. It also traces the potential effects of such policies if introduced prior to the subprime crisis. The work is performed within the National Institute Global Econometric Model, with a focus on Germany, Italy and the UK. Detailed banking sectors and addition of a macroprudential block to our model enable effects of policies to be captured. A systemic risk index tracks the likelihood of the occurrence of a banking crisis and establishes thresholds at which macroprudential policies should be activated by the authorities. Capital adequacy impacts the economy by acting on the spread between borrowing and lending of corporates and households, while loan-to-value transmits through its impact on the housing market. We find generally loan-to-value policy has a lesser effect than capital adequacy on crisis probabilities and net benefits, but there is considerable cross country variation. We show that the introduction of macroprudential policy prior to the crisis would have led to improvement in a number of key macroeconomic measures and might thus have reduced the incidence of the crisis.     

Alternative Approaches to Cost Containment in a Cap-and-Trade System

We compare several emissions reduction instruments, including quantity policies with banking and borrowing, price policies, and hybrid policies (safety valve and price collar), using a dynamic model with stochastic baseline emissions. The instruments are compared under the design goal of obtaining the same expected cumulative emissions across all options. Based on simulation analysis with the model parameterized to values relevant to proposed US climate mitigation policies, we find that restrictions on banking and borrowing, including the provision of interest rates on the borrowings, can severely limit the value of the policy, depending on the regulator-chosen allowance issuance path. Although emissions taxes generally provide the lowest expected abatement costs, a cap-and-trade system combined with either a safety valve or a price collar can be designed to provide expected abatement costs near those of a tax, but with lower emissions variance than a tax. Consistently, a price collar is more cost-effective than a safety valve for a given expected cumulative emissions outcome because it encourages inexpensive abatement when abatement costs decline.     

Bayesian analysis of Hong Kong's housing price dynamics

This paper uses a Bayesian vector‐autoregressive model with sign restrictions to estimate the underlying drivers of Hong Kong's housing price dynamics in the short run. While existing studies are useful in analysing housing valuation, little attention has been paid to the short‐run dynamics. In contrast, the present paper identifies short‐run drivers of housing prices using structural identification with theoretical underpinnings. We find that among the shocks that we have identified, bank lending shock and housing supply shock were the main factors affecting Hong Kong's housing prices. Low mortgage rates were another key factor that led to the significant increase in housing prices after the global financial crisis.     

A QUEST FOR UNFETTERED CREDIT: HOW MONETARY POLICY DRIVES CREDIT RISK TRANSFER OF STRUCTURED FINANCE PRODUCTS

This study examines the effects of monetary policy contractions on bank loans to households and firms and instruments in three different credit risk transfer (CRT) capital markets over two separate time periods (1995–2006 and 2007–2015). The findings show that in both periods, banks decrease business lending but increase lending to consumers through a combination of mortgage, auto, credit card, and student loans from more liquidity produced by consumer‐related CRT activity. Additional results reveal relative CRT movements toward securitized mortgages from bank mortgage debt over both periods and toward securitized and insured business loans from bank business debt in the latter period, which suggest vulnerabilities among interconnected credit markets.

The Impact of Treasury Yields on US Presidential Approval, 1960–2010

ABSTRACT

The ‘power of bond markets’ is a widely assumed and poorly understood feature of the global economy. We demonstrate that even in a bond market as stable as the United States this influence is considerable. In this article, we scrutinise a particularly direct influence, the impact of US Treasury yields on presidential approval rates. Our empirical analysis from 1961 to 2010 demonstrates that rising/falling bond yields lead to a decline/increase in approval rates. We show that this impact is mediated via the US mortgage market. The stronger the rise in mortgage rates, the stronger the influence of Treasury yields on presidential approval. We then outline the broader possible political impacts of this, particularly given foreign and domestic central bank ownership of US Treasuries.     

转移成本、价格歧视与银行竞争——基于霍特林模型的实证分析

在银行业竞争中,转移成本能够锁定消费者,使银行能够对锁定的消费者定一个较高的价格,但是,转移成本也使银行对没有被锁定的消费者的竞争更加激烈。研究发现,转移成本的存在增加了银行的利润,并且转移成本越高,银行从信贷中获得的利润越高。但是,当存在存款市场和贷款市场竞争时,由于价格歧视的存在,银行的利润随着转移成本的增加而降低,转移成本没有给银行带来优势。     

The transmission of bank capital requirements and monetary policy to bank lending in Germany

We investigate the transmission of changes in bank capital requirements and monetary policy, and their interaction, on German banks’ corporate loan growth and lending rates. Our results show that increases in capital requirements are associated with an immediate decrease in total domestic and cross‐border bank lending. Changes in the euro area's monetary policy stance are positively related to corporate loan interest rates in general. Regarding the interacting effect of national bank capital requirements and euro area monetary policy, we observe that the transmission of accommodative euro area monetary policy to corporate lending rates can be attenuated by contemporaneous increases in bank capital requirements. Moreover, more strongly capitalized banks increase their loan growth in response to accommodative monetary policy whereas, for weaker banks, increasing capital requirements implies a decrease in their corporate loan growth. Our results confirm a tradeoff between higher capital requirements and accommodating monetary policy originating from banks’ capital constraints.     

Bank loan portfolios and the Canadian monetary transmission mechanism

Abstract .  Following a monetary tightening, bank loans to consumers decrease. This is true for both mortgage and non-mortgage loans, and it is true for a tightening by the Bank of Canada that is, and is not, a response to a tightening by the Federal Reserve System. In contrast, business loans increase following a monetary tightening. The 'perverse' response of business loans cannot be explained by an increase in the demand for funds due to a reduction in real activity. These results are consistent with a change in bank portfolio behaviour in favour of business loans in response to a monetary tightening.     

Determinants of bank failures in the US revisited

This study investigates factors influencing the bank failure rate in the United States over the period 1970 to 2007. The bank failure rate was found to be an increasing function of the unemployment rate, the average cost of funds, volatility of the S&P 500 Stock Index, and charge-offs as a percentage of outstanding loans and a decreasing function of the mortgage rate on new 30-year fixed-rate mortgages. The evidence implies also that the Federal Deposit Insurance Corporation Improvement Act acted to reduce bank failures whereas the Riegle–Neal Interstate Banking Act of 1994 may inadvertently have (by increasing competition and/or increasing costs through branch bank expansion) induced increased bank failures.     

国库现金转存商业银行的货币政策效应研究——基于Hollenhorst扩展框架的分析

本文构建了国库现金转存商业银行对货币政策影响的分析框架,研究表明,国库现金转存商业银行的货币政策效应主要取决于存款扩张乘数、国库现金抵押需求、公众贷款需求和国库现金存款形成的贷款对国内商品和服务的需求水平等因素。存款扩张乘数越大,国库现金对商业银行信贷水平的影响就越强。国库现金存款的抵押债券需求比例对信贷供给造成了反向影响,抵押比例越高,商业银行必须留出越多的储备购买债券,从而政府国库现金存款的增加可能导致信贷增量的下降。在平滑国库现金影响的政策选择上,中央银行表现出一定的被动性,通过制定国库现金存款的区别法定准备金率是中央银行调控国库现金影响货币政策的重要手段。     

The interaction between bank solvency and funding costs: A crucial effect in stress tests

This paper presents new evidence on the empirical relationship between bank solvency and funding costs. Building on a newly constructed data set drawing on the supervisory data of 54 large banks from six advanced countries over 2004–2013, we use a simultaneous equation approach with panel data to estimate the contemporaneous interaction between solvency and funding costs. Our results and test statistics show that these two are (a) determined simultaneously and (b) more pronounced than suggested by the existing empirical literature. A 100‐bps increase in regulatory capital ratios is associated with a decrease of bank funding costs of about 113 bps. A 100‐bps increase in funding costs reduces regulatory capital buffers by 48 bps. Applying our estimation results to the 2014 EU‐wide stress test reveals that neglecting the solvency‐funding cost nexus leads to the systematical and significant underestimation of the impact of shocks on bank capital ratios.
