The Lee–Chang scandal (Korean: 이철희 장영자 어음 사기 사건, Yi Chol-hui–Jang Yeong-ja eoeumsagi sageon, "Yi Chol-hui–Jang Yeong-ja note fraud incident") was a serious South Korean financial scandal that unfolded in 1982 under the presidency of Chun Doo-hwan.
In this way, beginning with $7 million saved from the alimonies of her two former husbands, Jang came to personally manipulate almost $1 billion through her underground loan network, or 17% of the entire South Korean money supply.
The network was uncovered when one of the firms, whose notes Jang had resold at a discount, complained to the authorities.
Jang's husband, Lee Chol-hui, was a former deputy director of the KCIA and a classmate of Park Chung Hee.
Furthermore, Jang's brother-in-law, Lee Gyu-gwang, was the uncle of President Chun himself, and was held to have played a key role in allowing the fraud to take place.
