This paper aims to explore the effects of illiquidity on portfolio weight and return dynamics.

Using a novel continuous-time framework, the paper makes two key contributions to the literature on asset pricing and illiquidity. The first is to study the effects of illiquidity on portfolio weight dynamics. The second contribution is to analyze how illiquidity affects the risk/return dynamics of a portfolio.

The numerical results highlight that investors should be prepared for potentially large and skewed variations in portfolio weights and can be away from optimal diversification for a long time when adding illiquid assets to a portfolio. Additionally, the paper shows that illiquidity increases portfolio risk. Interestingly, this effect gets more pronounced when the return correlation between the illiquid and liquid asset is low. Thus, there is a correlation effect in the sense that illiquidity costs, as measured by the increase in overall portfolio risk, are inversely related to the return correlation of the assets.

This is the first paper that highlights that the increase in portfolio risk caused by illiquidity is inversely related to the return correlation between the liquid and illiquid assets. This important economic result contrasts with the widely used argument that the benefit of adding illiquid (alternative) assets to a portfolio is their low correlation with (traditional) traded assets. The results imply that the benefits of adding illiquid assets to a portfolio can be much lower than typically perceived.

This study aims to demonstrate and measure the impact of liquidity shocks on a bank’s solvency, especially when the bank does not hold sufficient liquid assets.

The proposed model is an extension of Merton’s (1974) model. It assesses the bank’s probability of default over one or two (short) periods relative to liquidity shocks. The shock scenarios are materialised by different net demands for the withdrawal of funds (NDWF) and may lead the bank to sell illiquid assets at a depreciated value. We consider the possibility of second-round effects at the beginning of the second period by introducing the probability of their occurrence. This probability depends on the proportion of illiquid assets put up for sale following the initial shock in different dependency scenarios.

We observe a positive relationship between the initial NDWF and the bank’s probability of default (particularly over the second period, which is conditional on the second-round effects). However, this relationship is not linear, and a significant proportion of liquid assets makes it possible to attenuate or even eliminate the effects of shock scenarios on bank solvency.

The proposed model enables banks to determine the necessary level of liquid assets, allowing them to resist (i.e. remain solvent) different liquidity shock scenarios for both periods (including eventual second-round effects) under the assumptions considered. Therefore, it can contribute to complementing or improving current internal liquidity adequacy assessment processes (ILAAPs).

The proposed microprudential approach consists of measuring the impact of liquidity risk on a bank’s solvency, complementing the current prudential framework in which these two topics are treated separately. It also complements the existing literature, in which the impact of liquidity risk on solvency risk has not been sufficiently studied. Finally, our model allows banks to manage liquidity using a solvency approach.

The paper examines how equity mutual funds manage their liquidity. Specifically, the authors investigate what strategies fund managers use to meet investor redemption demand, whether these strategies vary over time, whether different type of funds employ different liquidation practices in response to fund outflows, and whether liquidity strategies impact fund performance.

This study uses a sample of U.S. actively managed equity funds over the period 1990–2019. The authors use three different measures to capture funds' liquidity management practices. The authors examine the relationship between fund liquidity measures and net flow by estimating panel regressions over the entire sample period, on 2 sub-sample periods of different market conditions measured by the magnitude of implied market volatility (VIX), and on 2 sub-samples of funds with different liquidity profiles. The authors also examine the relationship between funds liquidity status and near-term performance through both a portfolio approach and regression analysis.

The authors find that on average, mutual funds reduce their cash position and the most liquid asset holdings to meet investor redemption demand. Furthermore, the authors find that fund managers choose different liquidity strategies under different market conditions. During highly volatile markets, mutual funds use cash and their most liquid assets to meet redemption demand while maintaining their portfolio liquidity. During low volatility markets, mutual funds rely heavily on cash but less on liquidity assets and tend to increase their portfolio illiquidity. Upon further examination of funds across portfolio liquidity profiles, the authors find that liquid funds increase portfolio liquidity when facing outflows, whereas illiquid funds maintain their portfolio liquidity position. The different liquidity strategies have significant impact on funds' near-term performance. Specifically, liquid funds underperform illiquid funds following the increase in their portfolio liquidity.

This paper contributes to the literature on liquidity management by asset managers by taking a holistic approach to examine funds liquidation practice at the portfolio holdings level. Considering the recent increase in market volatility, mutual fund liquidity management has drawn an increasing share of interest and attention from policy makers, investment professionals, and academia. This study covers both uncertain and stable market states during a long sample period and provides empirical evidence on the flow-induced liquidation decisions by equity mutual funds. In addition, this paper also contributes to the literature on mutual fund performance by providing evidence that funds' liquidity strategies significantly impact their near-term performance.

We suggest the method of evaluation of illiquid assets on the market in the presence of proportional transaction costs by using two consumption/investment models. We study an investor's implicit evaluation of an illiquid asset whose trading incurs a proportional transaction cost. We show that the investor assigns an implicit value between the bid and ask price and uses it for his investment and/or consumption decisions. We also show that the implicit value is an increasing function of the investor's liquidity ratio, which is a measure of liquidity of the investor's asset holdings.

This study aims to investigate the existence of contagion between liquid and illiquid assets in the credit default swap (CDS) market around the recent financial crisis. The authors perform analyses based on vector autoregression model and the dynamic conditional correlation model. The estimation of vector autoregression models reveals that changes in liquid CDS (LCDS) spreads lead to changes in illiquid CDS spreads at least one week ahead during the financial crisis period, whereas the leading direction is reversed during the post-crisis period. Moreover, the results are robust after controlling for structural variables which are proven as determinants of CDS spreads and are empirically supported. This study interprets that information was incorporated first into the LCDSs because of the flight-to-liquidity during the recent crisis period but there is a default contagion effect by reflecting illiquidity-induced credit risk after the crisis. Finally, the dynamic conditional correlation analysis also confirms the main results.

The purpose of this study is two‐fold. The first purpose is to properly measure the level of US property and liability (P/L) insurers liquidity creation, applying the liquidity creation measure developed by Berger and Bouwman. The second purpose is to identify factors affecting P/L insurers' liquidity creation using a regression. Particularly, this paper tests two competing hypotheses regarding the relationship between the level of capital and liquidity creation.

The paper calculates liquidity creation for the US P/L insurers. First, the paper categorizes all items in assets, liabilities and surplus into liquid, semi‐liquid, or illiquid. This process is based on the ease, cost, and time for insurers to meet their contractual obligation to obtain liquid funds or to pay off their liability. The paper also constructs the regression model to test the impact of insurers' surplus level on liquidity creation while controlling for the firm‐specific variables. The paper examines this relationship for the time period between 1998 and 2007.

Contrary to the study of depository institutions, the paper reports that P/L insurers are liquidity destroyers than liquidity creators. This paper also provides that liquidity destruction varies over time and differs among insurers in different size. The total amount of liquidity destruction ranges from 47 to 58 percent of insurer total asset. In addition, the results of a regression show that insurer capital is negatively related to the level of liquidity creation. This provides implications that insurers with lower level of capital face more regulatory requirements and are forced to meet liquidity demand more.

The level of liquidity creation and the trend of liquidity creation of P/L insurers are of particular interest to regulators and consumers because the level of liquidity creation as shown during the financial crisis has a significant adverse impact on the financial intermediaries.

The paper do not aware of any study that attempts to measure liquidity creation by insurers and its relationship with both organizational and financial characteristics. The paper reports that P/L insurers are, unlike depository institutions, liquidity destroyers. Whether or not P/L insurers create/destroy liquidity is an interesting economic question to shed light on the roles of P/L insurers as a financial intermediary.

The purpose of this paper is twofold: first, this paper measures how much liquidity is transformed by the US life insurance industry for the sample period; and Second, this study tests the “risk absorption” hypothesis and “financial fragility-crowding out” hypothesis to identify the impact of capital on liquidity creation in the US life insurance industry. In addition, a regression model is conducted to explore the relationship between liquidity creation and other firm characteristics.

In order to construct the liquidity creation measures, all assets and liabilities are classified as liquid, semi-liquid, or illiquid with appropriate weights to these classifications, which will then be combined to measure the amount of liquidity creation. In addition, a regression model is analyzed. The level of insurers’ liquidity creation is regressed on the capital ratio (surplus over total assets) and other financial and organizational variables to test two prevailing hypotheses.

This paper finds that the US life insurers de-create liquidity. The authors provide that the amount of liquidity de-creation is related to the size of insurers such that liquidity de-creation has increased as assets grow and that large insurers de-create most of liquidity. The US life insurance industry de-created $2.1 trillion in liquidity, i.e., 43 percent of total industry assets, in 2008. The empirical results support the “financial fragility-crowding out” hypothesis. Life insurers’ liquidity de-creation is mainly caused by the large portion of liquid assets, which is required by regulation and capital is not a main factor of liquidity de-creation.

There is no known study on the issue of liquidity creation by life insurers. Thus, the extent of liquidity creation by the life insurance industry, if any, is an empirical matter to investigate, but also an important matter to regulators and the academia since the products and business operations (e.g. asset portfolio and asset and liability management) of life insurers are different from those of property and liability insurers.

The purpose of this paper is to investigate how much liquidity banks create and how liquidity creation changed over time in the MENA countries and to examine the soundness of banks in these countries based on the CAME rating system, in addition to investigating the relationship between CAME ratios and liquidity creation of these banks.

The study regresses the CAME ratios together with other control variables to model liquidity creation. The robustness of the results is evaluated by using a different measure of liquidity creation and by excluding the observations of the Islamic banks.

The results show that the CAME rating system, as an indicator of bank soundness, is negatively related to bank liquidity creation. Specifically, capital adequacy, management efficiency and earning ability ratios affect the on-balance sheet components of liquidity creation, while asset quality ratio affects its off-balance sheet component.

The paper offers insights to regulators and banks managers in terms of better understanding of the negative relationship between CAME rating system and bank liquidity creation.

This paper sheds more light on the relationship between bank soundness and liquidity creation by using the ratios of the CAMEL rating system as an indicator of bank strength and soundness.

The purpose of this paper is to investigate the interrelationship between liquidity creation (LC) and bank capital in Vietnamese banking between 2007 and 2015.

A three-step procedure is used to measure LC. Thereafter, a simultaneous equations model with a three-stage least squares estimator is employed to examine the links between LC and bank capital.

The findings show that large banks mainly contributed a strong growth in LC in Vietnam between 2007 and 2015. The findings also indicate that off-balance sheet activities only played a small role in LC. In addition, the findings indicate a negative two-way relationship between LC and bank capital in Vietnam. The results of the robust checks reinforce the main findings.

The evidence shows that the implementation of Basel III may reduce LC and greater LC may increase banks’ insolvency. Consequently, this trade-off between the benefits of financial stability induced by tightening capital requirements and those of enhanced LC has important implications for Vietnamese authorities in strengthening the banking system.

This study is the first attempt to investigate the interrelationship between LC and bank capital in Vietnam, in which fat liquidity creation and non-fat liquidity creation are used and alternative measures of LC are also employed to provide robustness to the main findings.

This research examines the relationship between market power and liquidity creation in the specific context of bank profitability in the Vietnamese banking sector.

The study applies the methodology proposed by Berger and Bouwman (2009) to demonstrate the creation of bank liquidity through a three-step procedure for investigating the relationship between market power and liquidity creation. The three steps include non-fat liquidity (NFLC), fat liquidity (FLC) and system generalized method of moments estimation for panel data.

This study finds that liquidity creation increases when a bank has high market power. Further, highly profitable banks positively impact the market power of banks with regard to liquidity creation, relative to less profitable banks. Moreover, bank size, capital, economic growth and interest rate negatively influence bank liquidity creation, while credit risk positively relates to bank liquidity creation.

Measurements used in this study are based on the works of Berger and Bouwman (2009). There are specific variations, relative to Basel III. In addition, other variables significantly impact bank liquidity creation that have not been considered in the models, and a quadratic model should have been considered to measure market power and bank liquidity creation.

This study suggests that managers should control the liquidity of their banks by supervising vulnerable characteristics that have been mentioned herein and emphasizing improvements in profitability. Further, the government may consider encouraging banks to generate more liquidity by modifying regulations concerned with market power or reinforcing policies about improving the transparent business environment.

This study characterizes an attempt to examine the influence of market power on the liquidity creation of banks in Vietnam, which represents one of the most dynamic systems in Asia, with several varied participating banks. The current study also examines the same within the specific context of the modifying impact of the profitability of banks.
