Woori Bank announced on Monday that it has completed its first corporate derivatives transaction, arranging a £70 million (approximately $93 million) loan and corresponding interest rate swap for a London-based company through its London trading hub. The transaction, signed on September 29 in collaboration with Woori Bank's London branch, aims to reduce the borrower's uncertainty regarding borrowing costs by converting floating-rate payments to fixed-rate payments. Woori Bank has directly hedged the swap in the London market.
