With the [Singapore dollar’s] strength and stability, both international and regional businesses may opt to hold more of their working capital in [Singapore dollars], relying on the new payment network for efficient currency conversion,” he explained.
If that happens, it could weaken the purchasing power of other currencies in the region and result in higher imported inflation if central banks don’t intervene.
In such a scenario, authorities may feel the need to impose capital restrictions in order to protect their respective currencies, which could undermine the very purpose of establishing a regional payment network.
Regulations pose another challenge.
Central banks will have to address security and fraud issues, plus undertake the task of educating the public to embrace the new payment system, said Han.
“These factors can collectively contribute to a time-consuming process,” he warned.
This kind of coordinated action will require strong political will from regional leaders and it remains to be seen if ASEAN members can come together to successfully implement such an ambitious venture.
