32W26: Interbank rates ease as SBV expands net injection

During 32W26, the SBV expanded its net liquidity injection into the banking system via open market operations, continuing to offer longer-term repo tenors to address persistent short-term tightness. Following the central bank's liquidity support, interbank rates declined sharply across most tenors. On the FX front, the domestic USDVND exchange rate dropped significantly by 0.35% WoW to 26,205, aligned with a weaker U.S. dollar following weak U.S. labor data and a reversal to net buying by foreign investors on the HoSE after a 20-week selling streak.
