Top developments
Won rebounds on exporter flows and dollar weakness
On Friday, October 30, the South Korean won closed at 1,334.3 per dollar, strengthening by 2.5 won from the previous session. The currency gained ground as dollar index weakness and month-end dollar sales by Korean exporters (nego flows) outweighed the negative sentiment from a 6% drop in the KOSPI index. This move marks a reversal from October 28, when the won had weakened by 14 won to 1,337.7 per dollar amid foreigner dollar purchases.
Rupiah stabilizes below Rp18,200 after BI intervention
The Indonesian rupiah faced significant pressure earlier in the week, hitting a near five-month high of 18,223 against the dollar on October 27. By October 28, Bank Indonesia (BI) actively intervened in the market and absorbed government bonds (SBN) to stabilize the currency, which closed around Rp18,184 per dollar. As of October 30, the rupiah continued to strengthen, trading near Rp18,128, supported by expectations of further BI support.
Rupee jumps 50 paise on dollar retreat
The Indian rupee closed at 94.76 per dollar on Friday, October 30, gaining 50 paise from the previous close. This recovery follows a period of weakness driven by high oil prices and US Treasury yield volatility. The Reserve Bank of India (RBI) has also been active, reportedly intervening to support the rupee and opening special dollar windows for oil companies to manage import costs.
Local view
In Korea, financial media highlighted the resilience of the won despite the KOSPI's sharp decline, attributing the currency's strength to the "nego" (exporter dollar selling) season at the end of the month. Meanwhile, Indonesian outlets noted that BI's dual strategy of direct FX intervention and SBN absorption was crucial in preventing the rupiah from breaking past the psychological Rp18,200 level.
