The asymmetric behavior and procyclical impact of asset correlations

This paper examines the behavior of asset correlations with the market returns in the asymptotic single risk factor (ASRF) approach of the Basel II accord on regulatory capital requirement. Over a sample period from 1988 to 2007, we find that asset correlations are positively related to firm size, but negatively related to firm default probability. Asset correlations are also industry specific, as firms in media, transportation, pharmaceutical, and semiconductor industries exhibit higher asset correlations than those in retail and consumer staples. Most importantly, asset correlations are asymmetric and have a procyclical impact on the real economy after controlling for these effects. They tend to rise during economic downturns, but decline during economic upturns. The average magnitude of the rise is larger than that of the decline. These findings suggest that asset correlations may be underestimated during economic downturns, and may provide policy implications for the capital requirement framework.     

Prudential Regulation and the "Credit Crunch": Evidence from Japan

The underlying causes of sharp declines in bank lending during recessions in large developed economies, as exemplified by the U.S. in the early 1990s and Japan in the late 1990s, are still being debated due to the lack of any convincing identification strategy of the supply side capital–lending relationship from lending demand. Using within bank share of real estate lending in the late 1980s as an instrumental variable for bank capital, we find that Japanese banks cut back on their lending in response to a large loss of bank capital in fiscal year 1997.     

The Anatomy of Public and Private Real Estate Return Premia

Market-wide, stock market specific, and real estate market specific risk – what kind of risk and to which extent drives the returns of listed real estate? Based on a structural asset pricing model calibrated to the empirical data in the U.S., we show that at least two thirds of the risk premium of listed real estate are driven by the same factors as direct real estate. Our results shed new light on the risk-characteristics of listed real estate returns and are of high interest for academics, regulators, and portfolio managers alike.     

Did the U.S. Treasury’s capital purchase program (CPP) help bank lending and business activity?

The 2008 financial crisis led the U.S. Treasury to implement the capital purchase program (CPP) to revive commercial bank lending and hence stimulate business activity. Employing dynamic panel techniques and methodologies from the bank lending channel literature we find that after controlling for asset size, bank capital, and macroeconomic variables (real GDP growth rate and interest rate spreads), the impact of the CPP program is statistically significant only for money center banks. However, over our sample period from 2008Q3 to 2009Q4 we find a very modest impact on lending by only the largest banks. Overall, our results suggest that CPP’s business objective to boost loan growth and hence business activity during the crisis remained unfulfilled.     

Are real estate specializing depositories viable? Evidence from commercial banks

This study investigates whether depository institutions that concentrate on real estate lending are economically viable by examining the behavior of a sample of commercial banks that chose over the last decade to specialize in real estate lending. The results show that over the 1978–1988 period, the average real estate specializing bank earnings performance was on par with regular commercial banks, and those that were in the business for a longer period of time had higher returns with less risk than substantially more diversified commercial banks. Real estate banks has relatively lower loan losses and relatively higher proportions of lower risk, one- to four-family mortgage loans than regular commercial banks. Finally, it appears that real estate banks exhibited substantial flexibility in their ability to adjust their real estate loan holdings.     

Assessing targeted macroprudential financial regulation: The case of the 2006 commercial real estate guidance for banks

In January 2006, federal regulators issued guidance requiring banks with specific high concentrations of commercial real estate (CRE) loans to tighten managerial controls. This paper shows that banks with concentrations in excess of the thresholds set in the guidance subsequently experienced slower growth in their CRE portfolios than can be explained by changes in bank or economic conditions. Moreover, banks above the CRE thresholds tended to have slower commercial and industrial loan growth but faster household loan growth following issuance of the guidance. The results highlight the potentially broad influence that portfolio-based macroprudential regulation might have on bank behavior.     

Extending the Basel II approach to estimate capital requirements for equity investments

Under the Basel II banking regulatory capital regime the capital requirements for credit exposures are calculated using the Asymptotic Single Risk Factor (ASRF) approach. The capital requirement is taken to be the contribution of an exposure to the unexpected loss on the bank’s diversified portfolio. Here we extend this approach to calculate capital requirements for equity investments. We show that in the case when asset values have a normal distribution an analytical formula for the unexpected loss contribution may be developed. We show that the capital requirements for equity investments are quite different to those of credit exposures, since equity investments can suffer substantial loss of value even when the underlying company has not defaulted.     

Time-varying correlation between stock market returns and real estate returns

Direct investment in commercial or residential real estate is found to provide valuable diversification benefits for Australian investors though this is not so evident for indirect real estate investment vehicles like listed Australian real estate investment trusts (A-REIT). Further, multivariate analysis of Australian real estate and share market quarterly returns, spanning the period from the 3rd quarter 1986 to the 3rd quarter 2009, suggest that the correlation between real estate returns and share market returns is time-varying. Finally, while all of the asset class correlation coefficients increased with the Global Financial Crisis period this broad movement in asset class correlation is not evident in during the Wall Street Crash of 1987.     

Macroeconomic Factors and Microlevel Bank Behavior

We analyze the link between banks and the macroeconomy using a model that extends a macroeconomic VAR for the U.S. with a set of factors summarizing conditions in about 1,500 commercial banks. We investigate how macroeconomic shocks are transmitted to individual banks and obtain the following main findings. Backward‐looking risk of a representative bank declines, and bank lending increases following expansionary shocks. Forward‐looking risk increases following an expansionary monetary policy shock. There is, however, substantial heterogeneity in the transmission of macroeconomic shocks, which is due to bank size, capitalization, liquidity, risk, and the exposure to real estate and consumer loans.     

Tax liens: a novel application of asset pricing theory

Although relatively obscure, the market for distressed real estate tax liens exists in over 30 U.S. states, with a market size estimated to be around 20 billion dollars. While this niche asset class is relatively unknown to academics, internet advertising hypes tax liens to the populace as providing extraordinary returns. Not yet scientifically studied, this market provides a fertile and untouched arena for the application of asset pricing theory. Using insights from several areas of asset pricing, we formulate and test a pricing model for tax liens. The empirical evidence supports the pricing model, the (increasing) competitiveness of the tax lien market, and an unfair tax auction bidding mechanism for property owners that may provide extraordinary returns to investors, lending some credibility to the industry claims. We suggest avenues for extensions and further research.     

An analysis of the impact of timberland, farmland and commercial real estate in the asset allocation decisions of institutional investors

We examine the effects of including timberland, farmland and commercial real estate in a mixed asset portfolio with stocks, government bonds and T-Bills. Using both smoothed and unsmoothed returns (as per Geltner [Geltner, D. (1993). Estimating market values from appraised values without assuming an efficient market. Journal of Real Estate Research, 8, 25-345.]) and both constrained and unconstrained allocation assumptions (as per Eichhorn, Gupta and Stubbs [Eichhorn, D., Gupta, F., & Stubbs, E. (1998). Using constraints to improve the robustness of asset allocation. Journal of Portfolio Management, Spring, 41-48.]), we employ Markowitz portfolio optimization and find widely varying allocation outcomes. However, timberland entered nearly all portfolios, accounting for large percentages in several scenarios, while farmland entered only low-risk portfolios. At lower risk levels, commercial real estate dominates the real estate allocation but as acceptable risk levels rise, timberland supplants commercial real estate as the primary component of the portfolio's real estate allocation.     

Dynamics of Asset Prices and Transaction Activity in Illiquid Markets: the Case of Private Commercial Real Estate

This paper investigates the relationship between capital flows, turnover and returns for the UK private real estate market. We examine a number of possible implications of capital flows and turnover on capital returns testing for evidence of a price pressure effect, ‘return chasing’ behaviour and information revelation. The main tool of analysis is a panel vector autoregressive (VAR) regression model in which institutional capital flows, turnover and returns are specified as endogenous variables in a two equation system in which we also control for macro-economic variables. Data on flows, turnover and returns are obtained for the ten market segments covering the main UK commercial real estate sectors. Our results do not support the widely-held belief among practitioners that capital flows have a ‘price pressure’ effect on property prices. However, we do find a significant positive relationship between lagged turnover and contemporaneous capital returns, suggesting that asset turnover provides increased price revelation which, in turn, reduces investment risk and increases property values.     

偏低定价、贷款放宽与房地产价格——基于PW模型的中美比较及启示

Pavlov and Wachter(2004,2006)从市场竞争的角度发现住房信贷偏低定价是推动信贷过度扩张从而导致房地产价格膨胀的一个重要原因。本文认为流动性过剩将加剧这种现象,同时贷款放宽也是推动信贷过度扩张导致房地产价格上涨的重要原因。近年来在流动性过剩下中美两国住房信贷市场都出现了偏低定价和贷款放宽现象,其表现和产生的原因具有共性和个性。在中美比较的基础上,本文提出了对我国的几点启示。     

Bank Portfolio Allocation: The Impact of Capital Requirements, Regulatory Monitoring, and Economic Conditions

This paper develops a structural, dynamic model of a banking firm to analyze how banks adjust their loan portfolios over time. In the model, banks experience capital shocks, face uncertain future loan demand, and incur costs based on their proximity to regulatory minimum capital requirements and the intensity of regulatory monitoring. Implications of the model then are estimated using panel data on large U.S. commercial banks operating continuously between December 1989 and December 1997. The estimated model is used to simulate the optimal bank response to (1) past and proposed changes in capital requirements, (2) changes in regulatory monitoring intensity, and (3) economic downturns. The simulation results are used to shed light on the decline in loan growth and the rise in bank capital ratios witnessed over a decade ago as well as the possible impact of the current proposed modification to capital requirements.

Owner-occupied homes,income-producing properties,and REITs as inflation hedges: Empirical findings

New evidence on the correlation patterns of various real estate returns with inflation is presented. Returns on a wide array of real estate, nonresidential as well as residential, are investigated. Stock and bond returns are also analyzed for comparison purposes. Extensive heterogeneity is found in real estate return correlations with inflation. Nonresidential property returns are most strongly positively correlated with inflation, although the appreciation in owner-occupied homes is also positively associated with inflation. However, REIT returns tend to be strongly negatively correlated with inflation. In this respect, they look more like traditional stocks and bonds than any other type of real estate. Finally, new evidence on return correlations with energy prices is also presented. Nonresidential real estate performs best here, too, although no real estate asset fully compensates investors for adverse energy price shocks.     

U.S. credit union motivation for involvement in the first-mortgage market

U.S. credit union involvement in first-mortgage lending has grown rapidly since extended lending powers were granted through several regulatory changes from 1977 to 1984. The purpose of this study is to examine credit unions that initiated first-mortgage lending programs during the period 1983 through 1988, and attempt to identify factors or variables that influenced the decision to become active in the first-mortgage market. The results indicate that there are certain factors that distinguish credit unions that become involved in first-mortgage lending from those that do not. Specifically, the size of a credit union, a full-service orientation, and a residential type of membership bond were factors consistently significant in their relationship to first-mortgage initiation.     

The Basel Committee proposals for a new capital accord: implications for Italian banks

Following a few general considerations on the recently proposed revision of the Basel Agreement on capital adequacy, this paper focuses on the first pillar of the Basel Committee proposals, the handling of capital requirements for credit risk in the banking book. The Basel Committee envisages an approach alternatively based on external ratings or on internal rating systems for the determination of the minimum capital requirement related to bank loan portfolios. This approach supports a system of capital requirements that is more sensitive to credit risk. On the basis of specific assumptions, these requirements provide a measure of the value at risk (VaR) produced by models used by major international banks. We first address the impact of the standardised and (internal ratings-based) IRB foundation approach using general data on Italian banks loans' portfolios default rates. We then simulate the impact of the proposed new rules on the corporate loan portfolios of Italian banks, using the unique data set of mortality rates recently published by the Bank of Italy. Three main conclusions emerge from the analysis: (i) the standardised approach implicitly penalizes Italian banks in their interbank funding as their rating is generally below AA/Aa, (ii) the average default rate experienced by Italian banks is higher than the one implied in the benchmark risk weight (BRW) proposed by the Basel Committee for the IRB foundation approach, thereby potentially leading to an increase in the regulatory risk weights, and (iii) the risk-weight is based on an average asset correlation that is significantly higher than the one historically recorded within the Italian banks' corporate borrowers. These findings support the need for a significant revision of the basic inputs and assumptions of the Basel proposals. Finally, in relation to the conditions that allow the capital market to effectively discipline banks, we comment on the proposals advanced in relation to the third pillar of the new capital adequacy scheme.     

Asset correlations and bank capital adequacy

This paper addresses the estimation of confidence sets for asset correlations used in credit risk portfolio models. Research on the estimation of asset correlations using endogenous probabilities of default estimations has focused on the impact of concentration risk factors, such as firm size and industry. The empirical evidence from Italian small- and medium-size companies show that the assumptions underlying the Basel Committee regulatory capital risk weight function are not substantiated. The regulatory impact is that the capital adequacy is significantly compromised, driving an adverse selection, which favors the worst companies, and transferring the procyclical effects from firms to banks.     

Inflation and Asset Returns in a Monetary Economy

Postwar U.S. data are characterized by negative correlations between real equity returns and inflation and by positive correlations between real equity returns and money growth. These patterns are closely matched quantitatively by an equilibrium monetary asset pricing model. The model also implies negative correlations between expected asset returns and expected inflation, and it predicts that the inflation-asset return correlation will be more strongly negative when inflation is generated by fluctuations in real economic activity than when it is generated by monetary fluctuations.
