Tokeniser la dette souveraine consiste \u00e0 \u00e9mettre des obligations publiques sous forme de tokens num\u00e9riques. Ces tokens circulent sur des registres distribu\u00e9s ou des cha\u00eenes permissionn\u00e9es. L\u2019id\u00e9e gagne du terrain car la technologie permet de repenser l\u2019\u00e9mission, le r\u00e8glement et la garde des titres.<\/p>

Les banques centrales et les autorit\u00e9s de march\u00e9 testent ces approches en priv\u00e9. Elles cherchent \u00e0 am\u00e9liorer l\u2019efficience et la r\u00e9silience des march\u00e9s obligataires. Le contexte de num\u00e9risation des paiements et l\u2019av\u00e8nement des CBDC acc\u00e9l\u00e8rent ces exp\u00e9rimentations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Tokenisation d'actifs : un nouvel outil au service de l'\u00e9conomie r\u00e9elle - Les Echos<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Plusieurs architectures coexistent selon les objectifs. Certaines exp\u00e9riences utilisent des blockchains permissionn\u00e9es contr\u00f4l\u00e9es par des banques centrales et des d\u00e9positaires. D\u2019autres combinent des tokens sur des r\u00e9seaux publics avec des couches d\u2019acc\u00e8s restreint pour la r\u00e8glementation.<\/p>

Les tokens peuvent repr\u00e9senter une cr\u00e9ance fractionn\u00e9e, un droit de coupon ou un droit de remboursement. La distribution s\u2019op\u00e8re via des smart contracts<\/a> qui automatisent le paiement des int\u00e9r\u00eats et la gestion du capital. L\u2019interop\u00e9rabilit\u00e9 avec les syst\u00e8mes de r\u00e8glement classiques constitue un d\u00e9fi majeur.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

La tokenisation promet de r\u00e9duire les frictions de march\u00e9. Elle peut acc\u00e9l\u00e9rer le r\u00e8glement et diminuer les co\u00fbts de transaction. La fractionnalisation permet d\u2019ouvrir l\u2019acc\u00e8s \u00e0 une nouvelle base d\u2019investisseurs. La tra\u00e7abilit\u00e9 on-chain facilite la surveillance et la lutte contre la fraude.<\/p>

La programmabilit\u00e9 des titres autorise des m\u00e9canismes automatiques, comme le versement conditionnel de coupons. \u00c0 terme, ces am\u00e9liorations pourraient abaisser les co\u00fbts d\u2019\u00e9mission et accro\u00eetre la liquidit\u00e9 des march\u00e9s secondaires.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Toutefois, les risques restent importants. La conformit\u00e9 juridique des titres tokenis\u00e9s doit \u00eatre garantie dans chaque juridiction. Les interactions avec la politique mon\u00e9taire et la gestion de la dette publique demandent des garde-fous.<\/p>

Les questions de garde, de cyber-s\u00e9curit\u00e9 et de souverainet\u00e9 des infrastructures ne sont pas secondaires. La concentration de l\u2019infrastructure entre acteurs permissionn\u00e9s pose aussi un dilemme entre efficacit\u00e9 et r\u00e9silience. Enfin, la tokenisation peut modifier la structure de march\u00e9 et cr\u00e9er de nouveaux risques de liquidit\u00e9.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Aujourd\u2019hui, les exp\u00e9rimentations se multiplient discr\u00e8tement entre autorit\u00e9s publiques, banques et infrastructures de march\u00e9. Elles prennent la forme de pilotes, de projets de R&D et de consortiums priv\u00e9s.<\/p>

Avant toute g\u00e9n\u00e9ralisation, il faudra r\u00e9soudre les verrous techniques, aligner les cadres juridiques et mettre en place des standards interop\u00e9rables. Si ces conditions sont r\u00e9unies, la dette souveraine tokenis\u00e9e pourrait transformer la gestion de la dette publique et l\u2019acc\u00e8s aux march\u00e9s. Dans le cas contraire, elle restera une exp\u00e9rimentation utile mais limit\u00e9e \u00e0 des niches contr\u00f4l\u00e9es.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
