À propos de ces données

La dette publique des États-Unis est suivie à travers les encours, les taux d'intérêt moyens et les coûts d'intérêts mensuels par le United States Department of the Treasury, ventilée par titres négociables et non négociables, notamment les bons du Trésor (Treasury bills), les notes, les obligations (bonds), les TIPS et les obligations d'épargne (savings bonds), ainsi que les avoirs des comptes gouvernementaux.

Questions fréquentes

Quel est le taux d'intérêt moyen de la dette publique américaine ?
Il mesure le taux d'intérêt moyen pondéré payé par le département du Trésor des États-Unis sur l'ensemble des titres de la dette publique en circulation, reflétant les charges d'intérêts effectives plutôt que les rendements actuels du marché.
À quelle fréquence ces données sont-elles publiées et depuis quelle année sont-elles disponibles ?
Les données sont publiées chaque mois par le département du Trésor des États-Unis sur Fiscal Data et les séries historiques débutent en 2001.
Quels types de titres sont inclus dans ce tableau ?
Le tableau détaille les taux par titres négociables, tels que les bons du Trésor (Treasury bills, notes, bonds), les TIPS et les notes à taux variable, ainsi que les titres non négociables, comme les séries de comptes gouvernementaux et les obligations d'épargne.
En quoi cela diffère-t-il des rendements actuels du Trésor ?
Alors que les rendements du Trésor reflètent le coût de nouveaux emprunts sur les marchés actuels, le taux d'intérêt moyen de la dette publique englobe l'ensemble du portefeuille, s'ajustant progressivement à mesure que l'ancienne dette arrive à échéance et est refinancée.
