The reading marks an acceleration from August, when foreign currency deposits gained $1.13 billion, marking a turnaround from a $70 million drop in July. Foreign currency deposits include those held by foreigners who have stayed here for more than six months.

Foreign currency savings held by companies gained $1.12 billion to $57.01 billion over the cited period, while those held by individuals added $550 million to $15.63 billion.

The BOK noted both companies and individuals may have increased their foreign currency holdings on the slight advance of the local currency in the month.

At end-September, the local currency traded at 1,196.2 won to the greenback, up from 1,211.2 won per dollar a month earlier, the BOK said.

Savings in US dollars gained $1.32 billion to $62.16 billion, while those in Japanese yen added $210 million to $4.34 billion.

Deposits held by local banks came to $61.05 billion, accounting for 84 percent of the total.

However, savings held by foreign banks here grew at a faster clip of $1.18 billion to $11.59 billion. (Yonhap)
