Research PaperMSCI Liquidity Risk Monitor Report
During this unprecedented time, we are observing severe spikes in liquidity parameters. In order to keep you informed, we have created the MSCI Liquidity Risk Monitor Special Report, a weekly interim report, demonstrating the behavior of several liquidity risk indicators during the global COVID-19 crisis. Use this report to view movement of key liquidity indicators, as well as to communicate these trends with your internal and external stakeholders.
Research PaperMBS Performance through COVID-19
This Model Insight document discusses the performance and updates of MSCI Agency MBS prepayment and mortgage rate models through the COVID-19 pandemic.
Research PaperMSCI Agency Prepayment Model Updates
The document describes the impact of MSCI Prepayment Model updates for the 2020 Adverse Market Refinance Fee. Initially planned to be effective from September 1, 2020, this additional surcharge has been announced by Fannie Mae and Freddie Mac (Enterprises), to cope with the increasing credit loss related to COVID-19 pandemic. On August 25, 2020, Federal Housing Finance Agency (FHFA) directed the Enterprises to delay the implementation until December 1, 2020 and exempt refinance loans with...
Research PaperBuilding Single-Factor Portfolios
In this study, we focus on some of the issues investors face when constructing long-only non-optimized single-factor portfolios using simple heuristics-based rank-select-weight algorithms. In doing so, investors may ask: Should they start from a universe of securities with a fixed target-market-cap coverage or a fixed number of securities? Should they assess factor exposure based on single or multiple factor descriptors? How broad a subset of securities will they use from the underlying...
Research PaperLiquidity Risk Management for Funds: Part 2: Best Practices for Stress Testing
This is the second in a series of research papers proposing MSCI’s best practices for fund liquidity risk management. Here we propose best practices for liquidity stress testing at funds, drawing on guidelines from the European Securities and Markets Authority for undertakings for the collective investment in transferable securities (UCITS) and alternative investment funds. When designing market stress tests, we create both historical and hypothetical scenarios. Both cover at least three...
Research PaperLiquidity Risk Management for Funds: Part 1: Dilution Effects
This is the first in a series of research papers proposing MSCI best practices for fund liquidity risk management. These practices were developed over the past years in collaboration with asset-management firms that have adopted MSCI’s liquidity risk management tools. The objectives of this study are as follows: to draw a synthesis from the progress generated in the field of fund liquidity risk management and address fund liquidity risk management through a systematic formulation of the...
Research PaperA ‘Normal’ Choice of Interest-Rate Model for MBS
The valuation of mortgage-backed securities is highly dependent on the accuracy and mathematical construction of the chosen interest-rate models. In this document, we discuss two key aspects of the choice of an interest-rate model for MBS: volatility skew and correlation structures of forward rates.
Research PaperWhat Type of Companies Were Best Prepared for Remote Work?
COVID-19 disrupted the operating models of many businesses and forced a shift to remote working, digitization and low-contact transactions and services, which we term “Remote Operation Capability” (ROC). Some corporations were better positioned to take advantage of a remote, automated and digitized operating environment. We utilized machine-learning and natural language-processing techniques to build a potential ROC factor that looks at the extent to which a company was more likely to thrive...
Research PaperLiquidityMetrics Model Validation
LiquidityMetrics provides an analytical framework for liquidity risk management and regulatory reporting. This paper provides validation results for fixed-income securities through the lens of observed transaction costs. The validation period covers the relatively calm markets in 2019, as well as the onset and recovery from the COVID-19 crisis in 2020.
Research PaperRank-Based Error Tracking for Agency MBS Prepayment Models
Model testing, also called error tracking, is a key requirement for collateral behavior forecasting models in securitized products. The high dimensionality and statistical noise associated with agency mortgage-backed securities prepayment behavior makes error tracking a complex task. The traditional method focuses on a single dimension, and does not provide a clear measure of model accuracy and effectiveness. A rank-based error-tracking methodology provides an efficient and comprehensive...
