Vietnam's largest partly private bank, Vietcombank, was the first to announce it would cut lending rates, setting a maximum of 10 percent on medium and long-term loans in dong.
Vietcombank will also set aside about VND300 billion ($13.4 million) for business loans.
BIDV and Vietinbank have also made similar cuts. The three banks plus state-run Agribank are the country's largest lenders, accounting for 70 percent of the market.
Prime Minister Nguyen Xuan Phuc and State Bank Governor Le Minh Hung, in an online meeting with thousands of business people nationwide, called on commercial banks to cut lending interest rates to support domestic businesses.
