She said businesses would stand to gain by having improved access to a larger and a more secure source of financing for cross-border trade and investment activities.
In her address titled, "Roadmap of Financial Integration for Malaysia and Asean: What can Businesses Expect?", Zeti said the Asean bond market had more than tripled to US$1.1 trillion over the recent decade.
The Asean Exchanges, a collaboration of seven stock exchanges within the region, has a combined market capitalisation of US$2.9 trillion.
"Asean economies have now reached that stage of development in this decade whereby greater regional financial integration will raise further our growth potential.
"An important key to unlocking our full potential is to accelerate this integration and cooperation within the Asean region," she said.
The Governor said Asean had sustained high economic growth for more than three decades and was currently one of the fastest-growing and most dynamic regions in the world.
Economic growth in the region was expected to be sustained at an average of 5.3 per cent over the next five years to reach US$3.6 trillion by 2019, five times the size it was a decade ago, she said, quoting the International Monetary Fund.
By 2020, Asean is estimated to contribute to more than half of the total global middle class population, representing more than US$2 trillion of new consumption within the region, she added.
