In order to address the deficiencies in the banking regulation revealed by the recent financial crisis the Basel III introduces two minimum standards for funding liquidity, Liquidity Coverage Ratio (LCR) and Net Stable Funding Ratio (NSFR). The goal of this thesis is to analyze whether the NSFR is defined optimally or whether the Basel Committee on Banking Supervision (BCBS) will be forced to relax NSFR conditions similarly as happened by the LCR. Based on the approximation of the NSFR between 2007 and 2012 for a sample of 3 128 European banks we test the ability of banks to satisfy the NSFR. Our results suggest that the European banks have not started to converge to the NSFR yet. Despite this fact they should not have problems with meeting this requirement as 40.3% of banks in our sample would have already satisfied the NSFR in 2011. A Probit model analysis suggests that the NSFR requirement will decrease the probability of bank defaults and therefore increase the stability of the banking sector in the future which proves that the NSFR is correctly specified. Moreover, a simple stress testing shows that the stability of the system would not be improved anymore if the NSFR was defined more strictly. The current version of the NSFR therefore seems to be optimal and in our opinion should be...

Esse trabalho propõe a inserção de restrição de liquidez em um modelo de seleção de carteiras, visando aplicação no mercado brasileiro. No Brasil, a Comissão de Valores Imobiliários (CVM) expõe a importância do controle da liquidez de fundos de investimentos através de instrução publicada em 2012. A restrição proposta considera parâmetros utilizados nas normas brasileiras de controle de liquidez, como percentual do total negociado máximo, nível de liquidação e prazo para liquidação. O modelo é aplicado considerando-se diversos cenários, sendo variados parâmetros como valor da carteira formada e nível de liquidação aceitável, em diferentes intervalos de formação de carteiras. Verificam-se os níveis de liquidação das carteiras formadas e seu impacto no nível de risco das mesmas. Os resultados se mostraram consistentes, com bons níveis de percentual liquidado das carteiras formadas, próximos aos níveis de liquidação aceitáveis. Foi constatado também um aumento do nível de risco das carteiras mais restritas pela liquidez. / This work proposes the insertion of a liquidity constraint in a portfolio selection model, aiming to be applied in the Brazilian market. In Brazil, the "Comissão de Valores Imobiliários" (CVM) exposes the importance of controlling the liquidity of investment funds through the instruction published in 2012 . The constraint proposed in this work considers parameters used in the Brazilian regulatory standards of liquidity control parameters such as maximum percentage of monetary value, liquidation level and liquidation term date. The model is applied considering several scenarios, varying parameters such as the portfolio value and acceptable liquidation level, in different portfolio formation intervals. The liquidation levels of the portfolios formed and their impact on the risk of the portfolios are verified. The results were consistent, with good levels of liquidation of the portfolios formed, close to acceptable liquidation levels. There was also an increase in the risk of liquidity-restricted portfolios.

This dissertation studies the demand and supply of liquidity with a particular focus on the financial intermediation sector. The first essay analyzes the role of financial intermediaries as suppliers of inside money. The demand for money arises from the needs of nonfinancial corporations to buffer liquidity shocks. The dynamic interaction between inside money supply and demand gives rise to a mechanism of financial instability that puts the procyclicality of intermediary leverage at the center. Introducing outside money, in the form of government debt, can be counterproductive, as it may amplify the procyclicality of inside money creation and intermediary leverage, making booms more fragile and crises more stagnant. The second essay addresses an issue that is left out in the first essay -- the interaction between money and credit. It offers a model of macroeconomy where intermediaries are needed for both money and credit creation. Specifically, entrepreneurs hold money to finance new projects, while intermediaries issue money backed by investments in existing projects. The complementarity between money and credit arises from financial frictions and amplifies economic fluctuations. In the third essay, my coauthors and I model the liquidity demand of banks. To buffer liquidity shocks, banks hold central bank reserves and can borrow reserves from each other. The propagation of liquidity shocks, depend on the topology of interbank credit network, but more importantly, on the type of equilibrium on the network (strategic complementarity vs. substitution). The model is estimated using data on reserves, interbank credit, bank balance sheets, and macroeconomic variables. We propose a method to identify banks that contribute the most to systemic risk, and offer policy guidance by comparing the decentralized outcome with the choice of a benevolent planner.

As the demand for liquidity risk management has increased, the importance of comprehensive liquidity assessments of exchanges has been highlighted. This thesis investigates the liquidity on the Nasdaq OMX Stockholm exchange by using daily end of day data. The transaction cost is evaluated using the Holden model and the price impact from trading is evaluated using the Illiq model. Considering the three segments; small cap, mid cap, and large cap, the results suggest that both the transaction cost and price impact is highest for small cap stocks and lowest for large cap stocks. It is also shown that the transaction cost has decreased between 2002-03-20 and 2012-01-06 for all three segments although the cost is increasing for the small cap segment again. No decrease in price impact over this time period could be found. The data behind the results has then been used to create a combined liquidity measure with the purpose of indicating the liquidity condition of a mutual fund. The combined measure can also be used to assess whether it is price impact or transaction cost that contributes most to the liquidity cost when liquidating stocks or reveal what stocks in a portfolio that are the most illiquid. It is hence suggested as a tool for assessing large portfolios.

This study investigates the main drivers of excess liquidity in the financial sector of Lesotho using Vector Auto Regression (VAR) analysis. The study also undertakes a comparative analysis of Lesotho and CMA economies for economic and financial sector characteristics to benchmark and assist policy recommendation. The results of the study suggest that excess liquidity in Lesotho’s financial sector is driven by undeveloped financial sector as reflected by significant private sector credit to GDP ratio in the results, government expenditure and central bank activities in the open market operations, together with past levels of excess liquidity in the model. Compared to CMA, financial intermediary in Lesotho is relatively undeveloped with government dominating economic activity. The banking sector is observed to be non-competitive for deposits as hinted by the wide intermediation margin compared to other CMA countries.
