One of the main responsibilities of central banks is to ensure financial stability. In recents years the task is even more challenging with liberalisation and increasing integration with global markets. In this respect the SEACEN countries have learnt their lessons well by placing financial system stability as top priority and making concerted efforts to develop a more robust financial infrastructure. Prudential regulation has also been strengthened. Many countries plan to adopt the new capital accord – Basel II – to ensure a sound capital framework that measures risks adequately and allocates adequate capital to cover risks. Meanwhile several countries have adopted a master plan to restructure and develop a strong financial sector.
