Bank commercials of idols (and an old singer) - New Jeans, aespa and someone else

New Jeans - Shinhan Bank

aespa - KB Bank

Someone else - Woori Bank

Korean banks (although most of them are owned by foreign interests) are using idols to promote their institutions to further the reach on younger generations.

Shinhan Bank has been using New Jeans since 2022.

KB Bank has been using aespa from 2021 when aespa just started.

Woori Bank has been using someone else since 2022.

KB Bank did use BTS 2017-20 but thought aespa was fresher and changed it to the SM girl group in 2022, but Woori Bank , after using BlackPink in 2019, began using someone else in 2022.

Shinhan Bank is going for the younger demographic

KB Bank is going for mid-20s demographic

However Woori Bank's choice is quite curious since the former owner of Edam Entertainment appeals to those in the 30s and is significantly older than BP.

Quote from Prongs

The audacity to put IU as someone else

Well, the first two are part of KPop while someone else is not.

Quote from bbgc

Woori bank is smart.

What is the point of appealing to teens/twenties who have little money. It is the adults who are the demographic target for Financial products. And what is needed is not glamour, but 'reputation', when it comes to banking.

IU is the best fit of the three.

The real reason Korean banks use younger female idols to promote their institutions seems to be these

1. Built a lifelong relationship with someone entering society

2. Make the younger men stanning them to start banking with such institutions.

Lee Jieun can attract women in their 30s too so I think you are correct.
