KDB will discuss the matter with the Financial Services Commission and will make a decision on whether to lend the funds on Thursday or Friday, online news service Money Today reported earlier on Thursday, citing an unnamed KDB source.
A KDB spokesman declined comment.
Korean Air Lines , Hanjin Shipping's largest shareholder, agreed late on Wednesday to lend 60 billion won to help unload cargo.
The airline's loan is in addition to 40 billion won provided by the Hanjin Group's chairman, and 10 billion won provided by a former Hanjin Shipping chairwoman.
If Korea Development Bank decides to lend, the total is still short of the 173 billion won Hanjin estimated in a court submission early this month that it needed to unload all cargo.
Accounting for additional costs such as charter fees and fuel costs incurred since the court receivership began, Hanjin now estimates cargo unloading costs could reach about 270 billion won, a Seoul Central District Court judge said on Thursday.
Around 30 of Hanjin's 97 leased and owned container ships have completed unloading, South Korea's finance minister said on Wednesday. All chartered vessels have been ordered to be returned to their owners but dozens remain waiting at sea while funds are raised and protection from creditors is organised.
With debt of about 6 trillion won at the end of June and the South Korean government's unwillingness to mount a rescue, expectations are low that Hanjin Shipping will survive.
One opposition lawmaker angrily criticized the government in parliament on Thursday for not stepping in to save the company.
"It is heartbreaking that our biggest shipping company is in this situation, but we believed it would create a bigger problem if we started using taxpayers' money to resolve this problem," Finance Minister Yoo Il-ho said in response.
