Yield curve reactions to fiscal sentiment in Brazil

Abstract

Purpose Using a fiscal sentiment indicator, this study aims to verify whether fiscal sentiment affects the yield curve in Brazil. Since policymakers highlight the coordination between monetary and fiscal policies and the importance of fiscal policy to the expectations formation process in inflation targeting regimes, the authors also explore the transmission mechanism through inflation expectations. Hence, the study also analyzes the effect of fiscal sentiment on interest rate swap spreads through the inflation expectations channel. Design/methodology/approach Based on information obtained from official communiqués about fiscal policies issued by the Central Bank of Brazil and the Brazilian Ministry of Finance, the study builds a fiscal sentiment indicator. The econometric strategy to verify whether fiscal sentiment is related to the short tail of the yield curve is based on time series analysis through ordinary least squares and generalized method of moments estimates. In turn, to estimate the transmission mechanism through inflation expectations, the model uses interaction terms between fiscal sentiment and inflation expectations. Findings The results suggest a more optimistic (pessimistic) fiscal sentiment reduces (increases) swap spreads. The findings reveal that improvements in fiscal credibility and a more optimistic fiscal sentiment are able to reduce the positive marginal effect that inflation expectations variations have on interest rate swap spreads. Originality/value This study contributes to the literature, as, to the best of authors’ knowledge, it is the first to analyze the content of the communiqués related to fiscal policy, and based on this content, it extracts the sentiment related to the fiscal environment and analyzes the effect of this sentiment on the yield curve. Besides, different from existing studies that analyze the effect of fiscal backward-looking aspects (such as public debt, budget balance, taxes and public spending) on the yield curve, this study investigates forward-looking aspects related to fiscal policy (such as fiscal credibility and fiscal sentiment).
