We propose an efficient way to interpolate implied volatilities in between market expirations while keeping local volatilities virtually constant in time for any strike relative to forward. The method never creates an arbitrage. If the input volatilities are not arbitrage-free, the method...

Credit Default Swap (CDS) spread is a realistic measure of credit risk. Changes in the spreads showcase changes in the underlying uncertainty or credit volatility regarding the credit risk, associated with the asset class. We use Multifractal Detrended Fluctuation Analysis (MF-DFA) to further...

We study a firm's debt-maturity policy. The firm, keeping book leverage constant, rolls over expiring debt by newly issuing short- or long-term bonds, which pay different coupons. In equilibrium, we always find two balanced issuance regimes, which are associated with one type of debt: In bad...

We investigate the influence of the Central Bank of Brazil’s Monetary Policy Comitee (COPOM) decisions on the term structure of interest rate . We consider four possible drivers of market movements: (i) the effective surprise in the decision compared to market expectations; (ii) the asymmetric...

Structural credit risk models have faced difficulties in matching observed market credit spreads while simultaneously matching default rates, recoveries, leverage and risk premia - a shortcoming that has become known as the credit spread puzzle. We ask whether stochastic asset volatility, as an...

We examine the effect of the European Central Bank’s Quantitative Easing (QE) on sovereign bond spreads of crisis-prone EMU countries. Outcomes of panel regression models show that QE lowered the effect of volatility on sovereign bond spreads by one to two percentage points. Asset purchase...

This paper aims to explore whether text-based sentiment can perform well at predicting bond returns. We propose a sentiment trend factor based on the bond fear index that is a powerful predictor for future bond risk premia in- and out-of-sample. Notably, the text-based fear trend factor...

The paper studies the determinants of the interest rate spreads in Estonia, a country that stands out among European countries for its wide spreads. Four distinct credit markets are considered for housing loans, consumer loans, long-term corporate loans and short-term corporate loans. The paper...
