The Bank for International Settlements has published BIS Paper No 162, compiling a speech by Agustín Carstens and remarks from two panel discussions held at the 24th BIS Annual Conference on “Central banking in times of digitalisation and fragmentation”. The collection focuses on how rapid technological change, shifting macro-financial conditions and a more fragmented global environment are affecting monetary policy, payments and financial stability. Carstens’ speech links the post-pandemic inflation episode and high public debt to the need for monetary and fiscal policies to avoid working at cross purposes, while warning that fragmented politics and limited fiscal space could put central bank autonomy under pressure. He argues that authorities should prevent the “de-institutionalisation of money” by developing institutionally sound digital alternatives to privately issued crypto assets and stablecoins, and sets out a vision for a next-generation monetary and financial system combining tokenised central bank money, tokenised commercial bank deposits and tokenised assets within a robust governance framework anchored in the singleness of money and settlement finality. The tribute panel also highlights Carstens’ role in BIS initiatives including the BIS Innovation Hub, the “Innovation BIS 2025” strategy and work on cross-border payments that helped catalyse the G20 Roadmap for Enhancing Cross-border Payments, while linking his payments principles to Brazil’s Pix and the “Finternet” concept. In the policy panel, central bankers describe more complex trade-offs as uncertainty rises and fiscal constraints tighten, including communication challenges and the risk that central bank interventions are interpreted through the lens of fiscal dominance. The remarks cover approaches such as Chile’s “monetary policy corridor” and expanded use of microdata and higher-frequency indicators, South Africa’s work on a public payments utility to broaden access to cheap and instant digital payments, Korea’s dilemma between monetary easing and housing-price pressures alongside cautions about non-bank stablecoin issuance, and Switzerland’s assessment of how demographics, digital outsourcing risks and geoeconomic fragmentation can weaken policy transmission and complicate financial stability and crisis management.
