BANGKOK - Thailand is set to delay the launch of a controversial $14.3-billion "digital wallet" handout scheme until after May.

"Today, looking at the timeframe, it's unlikely for May," Deputy Finance Minister Julapun Amornvivat said on Wednesday, without specifying a new timeline.

While the government insists it will move ahead with the project, Julapun said there was no backup plan if the scheme could not be implemented.

The government has insisted the scheme, which would transfer 10,000 baht (around $285) each to 50 million Thais via a mobile app to spend in their local communities, would be managed carefully through cascaded borrowing.

It was also greenlit by an independent panel that provides legal guidance to governments, that said the scheme should only be rolled out in an economic crisis.

Earlier this week, amid calls from Srettha and his government to lower borrowing costs, the Bank of Thailand said adjusting interest rates could not be a "quick fix" for an economy that is weighed down by external factors like weak demand for its exports.
