VPBank talks add a fresh catalyst

Reuters reported on September 25, 2026, that Sumitomo Mitsui Banking Corp. was in advanced talks to raise its holding in Vietnam's VPBank from 15 percent to 20 percent. The report linked the possible increase to deeper access to Vietnamese consumers and businesses.

Reuters also reported that the parties remained divided over valuation, while SMBC considered open-market purchases instead of a private placement. That qualification matters because the potential transaction is still under negotiation.
