Woori Bank is resuming sales of its event-based installment savings product, the 'Woori Thrilling Lucky Savings' account. It is bringing the product back with a higher base rate after limited sales of 100,000 accounts ended in March.

Woori Bank said on Wednesday it would resume sales after raising the base rate by 0.5 percentage point to 3.0 percent a year.

The product was launched in November last year with a limit of 100,000 accounts. Its sales quota was fully used up by the end of March this year, and it has now been relaunched.

The contract term is 6 months. Customers can deposit up to 500,000 won a month with flexible payments, and can open up to 1 account per person on the Woori WON Banking app.

Preferential rates are applied through a monthly lucky-card draw. If selected in the draw, an additional 2.0 percentage points a year is added per card. If selected for all 5 lucky cards provided, customers can receive up to 10.0 percentage points a year in preferential rates. Adding the 3.0 percent base rate brings the maximum rate to 13.0 percent a year.

Yoon-jung Lee (이윤정), a deputy manager at Woori Bank's Retail Product Marketing Department, said, "Adding high interest-rate benefits to the fun element of the lucky card will be a good option for customers." She added, "We will continue to expand participatory financial products and services."
