DB Securities will increase the size of its public corporate bond sale to as much as 200 billion won after securing institutional orders worth more than four times the amount it sought in bookbuilding.

DB Securities said on Thursday it received 660 billion won in valid buy orders in bookbuilding held on Tuesday for its unsecured public bonds, against a planned 150 billion won offering. The overall bid-to-cover ratio was 4.4 to 1.

Following strong demand, DB Securities decided to raise the issuance size from the initial 150 billion won to the maximum target of 200 billion won.

By maturity, institutional investors submitted 340 billion won of orders for 70 billion won of 1.5-year notes and 320 billion won for 80 billion won of 3-year notes.

The coupon was set below each tranche's individual fair yield across the curve. The spread was set at minus 3 basis points for the 1.5-year notes and around minus 7 basis points for the 3-year notes.

The company said DB Securities' performance and financial soundness appeared to have helped secure institutional demand even as global interest-rate volatility has risen and bond-market sentiment has weakened.

DB Securities posted 116.7 billion won in consolidated operating profit in 2025 and earned 77.8 billion won in operating profit in the first half of this year. The company said it is continuing real estate project financing risk management and profitability improvements.

Funds raised through this bond sale will be used to repay maturing electronic short-term bonds, among other purposes. It plans to reduce the share of short-term funding and extend its borrowing structure to cut the burden from interest-rate fluctuations.

DB Securities is diversifying its funding sources, following a hybrid capital securities issuance in June and now a public corporate bond sale.

A DB Securities official said, "We successfully wrapped up the hybrid capital securities issuance in June, and this public corporate bond issuance was also a success," adding, "Based on the funds secured, we will strengthen sales competitiveness and market responsiveness across all business divisions."
