Denmark plans to classify six of its banks as "too big to fail".
This means they could face tougher capital rules and increased supervision as the government seeks to reduce the risk of future financial crises.
A government committee charged with looking into the banking sector said the country's ''Systemically Important Financial Institutions'' were Danske Bank, Jyske Bank, Nykredit, Nordea Bank Danmark, BRFkredit and Sydbank.
"These are institutions which are so large that they can impact the entire financial system and the economy, should they encounter problems," said Annette Vilhelmsen, minister for business and growth.
According to the proposal, the total capital requirement for the six Danish banks would be 15.5% of risk weighted assets, in line with requirements for SIFIs in neighbouring Sweden.
They would also hold a crisis management buffer, amounting to 5% of risk-weighted assets and which would be established over a three-year period starting in 2020.
The proposals need to be approved by parliament to come into effect.
