<h1>Central banking cooperation enhances regional resilience through coordinated capital flow, monetary, CBDC, big data, and climate risk policies.</h1> SEACEN serves as a supra national capacity building forum enabling member central banks to coordinate on capital flow management, monetary policy responses to disinflation, CBDC design and trials, big data applications for policy and supervision, and assessment of climate related macro financial risks. Emphasis is on mixed use of capital flow measures and macroprudential instruments, tailored monetary tightening to manage inflation and capital movements, two tier CBDC architectures for payment resilience, deployment of machine learning and suptech with attendant governance challenges, and integrating climate vulnerability into sovereign and financial stability analysis.
