Top developments
Vietnam SBV drains record liquidity, overnight rates drop to 1%
On September 11, the State Bank of Vietnam (SBV) conducted open market operations that resulted in a net drain of 37.6 trillion VND from the interbank system. This aggressive liquidity absorption pushed the overnight interbank lending rate down to approximately 1%, a significant decline from previous levels. The move signals the SBV's intent to manage domestic money supply tightly, likely to support the VND against dollar strength and curb inflationary pressures, while banking sector deposit rates remain elevated at up to 8.7% for longer tenors.
Regional bond yields rise on soft auction demand
Southeast Asian sovereign yields have dipped recently but are facing upward pressure due to softer bid-to-cover ratios in recent auctions and higher global benchmark rates. Fund managers are eyeing these higher yields as potential buying opportunities, despite lingering concerns over inflation and oil-driven costs. This trend creates a divergence where local currencies may face pressure if capital outflows accelerate in search of better risk-adjusted returns elsewhere.
EM Asia bonds stabilize in August despite global headwinds
According to a recent monthly report, Emerging Asia (ex China) government bond markets stabilized in August, with yields falling in the Philippines and Indonesia. This stabilization was driven by lower inflation prints in Indonesia and weaker growth data in the Philippines, which tempered hawkish expectations. The report noted that Malaysian and Indian yield curves remained the most stable, reflecting investor confidence in their respective policy regimes.
Local view
Vietnam: Local media highlights the "dynamic balance" challenge for Vietnamese policymakers. Tap Chi Kinh Te Tai Chinh notes that while the SBV is successfully managing short-term liquidity, the tension between high bank deposit rates (up to 8.7%) and the need to stabilize the USD/VND exchange rate remains acute. CafeF reports that the USD index dropping below 99 points provided temporary relief for the VND, allowing domestic banks to adjust rates downward slightly, but warns that external variables could return by year-end.
Thailand: Thai financial portal InfoQuest reported on the Bank of Thailand’s (BoT) bond auction results from September 10, noting a yield of 1.02356% for the 4-month instrument. This aligns with the BoT's stance of holding the policy rate at 1.00%, as reported by The Bangkok Insight, which emphasized the committee's unanimous decision to maintain accommodative conditions to support a fragile economic recovery.
