Price distortions and municipal bonds premiums: evidence from Switzerland

This study examines the pricing of municipal bonds before and after a currency shock in Switzerland. Two approaches are used to decompose the municipal to treasuries bond spreads into liquidity, maturity, and default risk premiums. The first approach is the model of the cross-sectional instrumental variables, and the second approach is the model of the instrumental variables with panel data. This study examines the composition of spreads for both approaches, in three scenarios: before, throughout, and after the currency shock. The study performed Durbin-Wu-Hausman tests for each decisive model to verify endogeneity issues, including the Lagrangian Multiplier test, the Cragg-Donald Wald F statistic to confirm the relationship of instrumental and endogenous variables, and the structural break test (Bai-Perron test) to determine the existence of structural breaks in bond distortions. This study finds that the currency price distortions of the Swiss franc in January 2015 made long-run changes in the composition of the municipal bond spreads. This research contributes to the understanding of municipal bond pricing by showing that default risk accounts for a large portion of the municipal bond spread, while maturity risk plays a lesser role. According to our empirical findings, unexpected large currency price shocks may have long-term implications on the municipal bond spreads.

Dealer Inventory Constraints in the Corporate Bond Market during the COVID Crisis

Beginning in late February 2020, market liquidity for corporate bonds dried up and corporate bond credit spreads soared amid broad financial market dislocations related to the COVID-19 pandemic. The causes of this liquidity dry-up and the spike in corporate bond spreads remain subjects of debate.

Euro, dollar or Swiss franc: which currency had the greatest impact on the Hungarian, Polish and Czech economies during the global financial crisis?

The article presents an analysis of the impact of foreign currency dynamics on the fundamentals (basic indices of the economic performance) of the Czech Republic, Hungary and Poland during the financial crisis of 2007/2008 and its aftermath until 2017. The subject of the analysis are three currencies: the US dollar, the euro and the Swiss franc. The assessment of their impact on the fundamentals of the three above-mentioned economies is based on the joint volatilities of bond spreads and currencies. A series of copula-GARCH models was estimated. The research demonstrates that the impact of foreign currencies was the strongest in the case of Poland and Hungary, as these two countries were more dependent on loans in foreign currencies than the Czech Republic. Another finding shows that the impact decreased significantly in Hungary after its government introduced loan conversion.

Common Factors in the Term Structure of Credit Spreads and Predicting the Macroeconomy in Japan

This study extracts the common factors from firm-based credit spreads of major Japanese corporate bonds and examines the predictive content of the credit spread on the real economy. Instead of employing single-maturity corporate bond spreads, we focus on the entire term structure of the credit spread to predict the business cycle. We extend the dynamic Nelson-Siegel model to allow for both common and firm-specific factors. The results show that the estimated common factors are important drivers of individual credit spreads and have substantial predictive power for future Japanese economic activity. This study contributes to the literature by examining the relationship between firm-based credit spread curves and economic fluctuation and forecasting the business cycle.

Sovereign Credit Quality and Violations of the Law of One Price

It is well-documented that government bonds with almost identical cash flows can trade at different prices. This paper analyzes the cross-section of bond spreads across developed European countries and documents a novel result. While a measure of the convenience yield of government bonds helps explain these spreads, it cannot explain the behavior of bond spreads in periods of widening credit risk. The paper documents bond spreads between new and old issues tighten for low quality sovereigns. In other words, the newer more liquid bonds become cheaper, not more expensive, relative to their older counterparts. We offer an explanation based on price pressure and provide empirical support using data on net flows of investors in sovereign bonds.

The Nonlinear Dynamics of Corporate Bond Spreads: Regime-Dependent Effects of their Determinants

This paper studies the behavior of corporate bond spreads during different market regimes between 2004 and 2016. Applying a Markov-switching vector autoregressive (MS-VAR) model, we document that the dynamic impact of spread determinants varies substantially with market conditions. In periods of high volatility, systematic credit risk—rather than interest rate movements—contributes to driving up spreads. Moreover, while market-wide liquidity risk is not priced when volatility is low, it becomes a crucial factor during stress periods. Our results challenge the notion that spreads predominantly capture credit risk and suggest it must be reassessed during periods of financial distress.
