41W26: SBV drains liquidity and USDVND eases

In 41W26, the SBV continued its net liquidity withdrawal for a second week as repo maturities exceeded new issuances. This cash drain pushed short-term interbank rates sharply higher, while longer tenors remained calm amid lower market turnover. Meanwhile, the domestic USDVND exchange rate dropped noticeably, bucking global greenback strength and absorbing heavy foreign net selling, backed by elevated interest rate differentials.
