The country's savings rate is declining at a time when the population is ageing, raising concerns about the number of people who will be able to provide for their retirement.

The erosion of savings was seen in particular in the household sector, at 4% of GDP against 11-12% a decade earlier, according to Atchana Waiquamdee, a Bank of Thailand deputy governor.
