Shinhan Financial Group (KRX:055550) amended a July 23 board decision to issue up to ₩400 billion of write-down contingent capital securities (Korea's equivalent of Additional Tier 1 hybrid capital), confirming the first tranche at ₩270 billion with subscription and payment on September 14. The amendment splits the use of proceeds differently than originally stated: general operating funds fall from ₩270bn to ₩160bn, while ₩110bn is now earmarked for debt repayment that wasn't itemized before — the total raise is unchanged, only its internal allocation. The bonds are perpetual with no fixed maturity, carrying a call option Shinhan may exercise after five years (subject to regulator approval) every quarterly interest date thereafter; coupon and final size will be set by investor demand within the ₩400bn ceiling the board approved. The stated purpose is to boost Shinhan's Basel III capital ratio (BIS ratio) by adding Additional Tier 1 capital, distinct from its common equity Tier 1 buffer already discussed in prior analyses on this site.
