A comment on mortgage procylicality
2012
This paper comments on mortgage procyclicality. A framework for credit constraints along the lines of Kiyotaki and Moore (1997) is applied to illustrate a potential regime shift in the credit risk assessments of mortgagees. Depending on the relationship between house price growth and the alternative rate of return the weight given to collateral and debt-servicing ability may vary according to the house price cycle as mortgagees engage in search-for-yield. The regime shifts induced by increased global liquidity and expectations of continued housing appreciation might stimulate owner-occupation and LTV-ratios and induce mortgage procyclicality.
The response of Brent crude oil to the European central bank monetary policy
2022
Este artículo examina el impacto de las decisiones de política monetaria del Banco Central Europeo (BCE) sobre los precios del petróleo y la liquidez mediante un estudio de eventos con datos intradía. Analizamos el período de enero de 1999 a diciembre de 2020, que incluye la crisis financiera que comenzó en agosto de 2007. Nuestros resultados muestran una respuesta significativa de los rendimientos del petróleo solo durante la crisis financiera. Específicamente, encontramos que los rendimientos de los futuros de petróleo crudo Brent respondieron negativamente a variaciones inesperadas en la prima de riesgo italiana como medida de acciones de política monetaria no convencionales, y positivam…
Anatomy of Risk Premium in UK Natural Gas Futures
2015
In many futures markets, trading is concentrated in the front contract and positions are rolled-over until the strategy horizon is attained. In this paper, a pair-wise comparison between the conventional risk premium and the accrued risk premium in rolled-over positions in the front contract is carried out for UK natural gas futures. Several novel results are obtained. Firstly, and most importantly, the accrued risk premium in rollover strategies is significatively larger than conventional risk premiums and increases with the time to delivery. Specifically, for strategy horizons between three and six months, this difference increases from 1% to 10%. Secondly, it is the first time that risk …
Rolling Over EUAs and CERs
2012
Whatever derivative contract has a finite life limited by their maturity. The construction of long series, however, is of interest for academic, hedging and investments purposes. In this study, we analyze the relevance of the choice of the rollover date on European Union Allowances (EUAs) and Certified Emissions Reduction (CERs) futures contracts. We have used five different methodologies to construct long series and the results show that, regardless of the criterion applied, there are not significant differences between the resultant return distribution series. Therefore, the least complex method, which is to roll on the last trading day, can be used in order to reach the same conclusions.…
Il PAV di Torino, un parco in movimento
2013
Nella “liquidità” contemporanea, la possibilità di una cura dell’afasia diffusa impone un ripensamento che coincide con la parola ri-uso, nella sua accezione di recupero di senso, traduzione, riconversione. In una parola trasformazione. In una poetica del riuso, nella sua accezione di ritorno alla vita e trasformazione, s’inserisce il PAV - Parco Arte Vivente di Torino, con la sua architettura semi-ipogea. Attraverso l'esperienza del PAV, centro sperimentale di arte contemporanea, si analizza il ruolo del museo nei processi di trasformazione urbana. In contemporary "liquidity," the possibility of a cure for widespread aphasia imposes a rethinking that coincides with the word re-use, in its …
Network-Based Computational Techniques to Determine the Risk Drivers of Bank Failures During a Systemic Banking Crisis
2018
This paper employs a computational model of solvency and liquidity contagion assessing the vulnerability of banks to systemic risk. We find that the main risk drivers relate to the financial connections a bank has and the market concentration, apart from the size of the bank triggering the contagion, while balance sheets play only a minor role. We also find that market concentration might facilitate banks to withstand liquidity shocks better while exposing them to larger solvency chocks. Our results are validated through an out-of-sample forecasting that shows that both type I and type II prediction errors are reduced if we include network characteristics in our prediction model.
High-frequency trading and networked markets
2021
Financial markets have undergone a deep reorganization during the last 20 y. A mixture of technological innovation and regulatory constraints has promoted the diffusion of market fragmentation and high-frequency trading. The new stock market has changed the traditional ecology of market participants and market professionals, and financial markets have evolved into complex sociotechnical institutions characterized by a great heterogeneity in the time scales of market members’ interactions that cover more than eight orders of magnitude. We analyze three different datasets for two highly studied market venues recorded in 2004 to 2006, 2010 to 2011, and 2018. Using methods of complex network th…
Liquidity-adjusted value-at-risk optimization of a multi-asset portfolio using a vine copula approach
2019
Abstract This paper develops a novel approach to assess liquidity-adjusted Value-at-Risk (LVaR) optimization of multi-asset portfolios based on vine copulas and LVaR models. This framework is applied to stock markets of the G-7 countries, gold, commodities and Bitcoin. The results show that our approach is superior to the classical mean–variance Markowitz portfolio technique in terms of the optimal portfolio selection under a number of realistic operational and budget constraints. We find that both Bitcoin and gold improves the risk-return performance of the G-7 stock portfolio. However, Bitcoin (gold) performs better under a scenario of only long-positions (when short-selling is allowed).
The adaptive nature of liquidity taking in limit order books
2014
In financial markets, the order flow, defined as the process assuming value one for buy market orders and minus one for sell market orders, displays a very slowly decaying autocorrelation function. Since orders impact prices, reconciling the persistence of the order flow with market efficiency is a subtle issue. A possible solution is provided by asymmetric liquidity, which states that the impact of a buy or sell order is inversely related to the probability of its occurrence. We empirically find that when the order flow predictability increases in one direction, the liquidity in the opposite side decreases, but the probability that a trade moves the price decreases significantly. While the…
THE KEY ROLE OF LIQUIDITY FLUCTUATIONS IN DETERMINING LARGE PRICE CHANGES
2005
Recent empirical analyses have shown that liquidity fluctuations are important for understanding large price changes of financial assets. These liquidity fluctuations are quantified by gaps in the order book, corresponding to blocks of adjacent price levels containing no quotes. Here we study the statistical properties of the state of the limit order book for 16 stocks traded at the London Stock Exchange (LSE). We show that the time series of the first three gaps are characterized by fat tails in the probability distribution and are described by long memory processes.
