The won led losses in Asian currencies this week after the Bank of Korea signaled its concern that economic growth is slowing amid speculation Japan will add to measures that weaken the yen.
South Korea’s currency had its biggest weekly decline in six weeks after the central bank left interest rates on Thursday and officials said the value of the yen, which has lost 9.8 percent against the US dollar this year, poses a threat to the economy.
“A number of factors are impacting the won: The first is the hit to Korean sentiment on the back of ongoing yen weakness and the second factor is the possibility of a rate cut spooking the markets,” Barclays PLC strategist Nick Verdi said in Singapore.
The won fell 1.8 percent this week to 1,110.95 per US dollar in Seoul, data compiled by Bloomberg show. Malaysia’s ringgit declined 0.8 percent to 3.1304 and Indonesia’s rupiah dropped 0.2 percent to 9,705.
In Taipei, the New Taiwan dollar rose 0.1 percent on Friday to NT$29.762 against its US counterpart, paring its weekly loss to 0.2 percent as exporters shifted to the buy side for the currency after the unit’s decline a day earlier to take advantage of a more favorable exchange rate, dealers said. It touched NT$29.81 on Monday, the weakest since Sept. 10 last year.
The central bank intervened again to prop up the greenback, helping the currency recoup some of its earlier losses in a bid to slow the pace of the NT dollar’s appreciation and boost the country’s global competitiveness, the dealers said.
Traders forecast that the central bank will continue its efforts to keep the Taiwan dollar cheaper, on expectations that the Bank of Japan will keep pumping funds into the market to lower the value of the yen, which could increase a currency depreciation competition in the region, the dealers said.
Concerns over a regional currency depreciation war have been running deeper, in particular after the new appointments to the Japanese central bank.
