ADB attributed the increase to the growing role of local currency bonds as a recent source of funds for companies and governments to support economic stimulus packages and market reforms.
The region needed to broaden further the investor base, strengthen market infrastructure and put in place a sound regulatory framework to facilitate fixed income markets to assume their full role in the region's economies.
East Asia comprising China, Hong Kong, Indonesia, South Korea, Malaysia, the Philippines, Singapore, Thailand and Vietnam, currently make up around six per cent of the global bond market.
