Gilts britanniques
UK 10-year gilt: 5.25% au 9 September 2026 · Bank of England IUDMNZC. Méthodologie
Les gilts sont des obligations émises par le UK Debt Management Office pour HM Treasury. Un gilt conventionnel verse un coupon sterling fixe deux fois par an et rembourse 100 £ de nominal à une date d'échéance indiquée. Les gilts indexés scalent ces flux avec un indice d'inflation publié ; les gilts verts restent du crédit britannique, avec une étiquette d'affectation des fonds.
Le rendement du gilt à 10 ans est le taux auquel s'accrochent les crédits immobiliers britanniques, les retraites à prestations définies et les spreads de crédit sterling. Nous affichons la série IUDMNZC de la Bank of England sur le tableau en direct, avec la date d'observation sur la carte — pas une capture d'écran sans date.
Ces pages expliquent la mécanique : enchères, cours dirty versus clean, duration, et en quoi les gilts diffèrent des produits NS&I et des Treasuries en dollars. Ce n'est pas un service de négociation.
