اثرات فرکانس پایین اخبار اقتصاد کلان بر سود اوراق قرضه دولتی

Are macroeconomic releases important drivers of Treasury bond yields? We develop a two-step regression strategy that fully exploits the available high-frequency market reaction data to identify the impact of macroeconomic releases and to quantify the effects at lower frequencies. While macroeconomic surprises explain only one tenth of the daily variation in bond yields, their explanatory power improves substantially at lower frequencies, accounting for one third of quarterly variations. The finding is explained by the persistent effects that macroeconomic surprises exert on bond yields, and a less persistent impact of residual factors, which tend to average out when focusing on longer-horizon changes.
