"The aggregate value of all capital and liquidity measures adopted by the CBUAE since 14 March 2020 has reached 256 billion dirhams ($70 billion)," the central bank said in a statement.
Last month, oil-rich UAE announced stimulus worth $35 billion that included aid to the banking system, facilities for loans and injecting funds into the bourses.
Most of the new measures focused on easing financial and liquidity requirements for banks to free up cash for lending.
In the new measures, the central bank reduced by half to 7.0 percent the reserves banks are required to keep for demand deposits, which can be withdrawn by clients anytime.
This will allow for some $16.6 billion in liquidity to be used in new bank lending, the central bank said.
The regulator's new measures also allow banks to defer payment of loans for companies and clients until the end of 2020.
"The additional measures announced today will effectively relieve the pressure on financial institutions ... offering the required relief and continued access to funding for businesses and households," newly-appointed governor Abdulhamid Saeed said.
