Indian Banks Association (IBA) chairperson Usha Ananthasubramanian said there is an urgency to fast-track SWIFT-CBS linkage.
This came after the country's second largest state-run lender Punjab National Bank detected a Rs 11,400-crore fraudulent transactions at one of its branches in Mumbai.
The firms of diamond jewellers Nirav Modi and Mehul Choksi allegedly acquired fraudulent letters of undertaking (LoU) from PNB's Brady House branch in South Mumbai to secure overseas credit from other lenders.
Asked about the April 30 deadline, Ananthasubramanian said, "Correct. That could be a deadline, but it is an outer limit. Today, the urgency is such that everyone wants this (linkage of SWIFT to CBS) project to be on fast-track". CBS is a software used to support most common transactions of a bank.

In a release issued earlier this week, the RBI said it had alerted banks three times since August 2016 for a possible misuse of the SWIFT infrastructure.
"The risks arising from the potential malicious use of the SWIFT infrastructure, created by banks for their genuine business needs, has always been a component of their operational risk profile.
Ananthasubramanian, who is currently managing director and CEO of Allahabad Bank, said at her bank SWIFT and CBS is not linked. The bank has sent all its branches memos to take precautionary measures.
She said there is an urgent need for all banks to revisit their risk management system to plug any loophole.
"Banks are reviewing and revisiting the systems to ensure drawbacks/loopholes, if any, are addressed so that the system becomes robust. SWIFT linkage to CBS is being fast- tracked by banks".
Last week, in a regulatory filing, Allahabad Bank had said it has an exposure of nearly USD 366.87 million in the form LoUs issued by PNB.
"The bank, through its overseas branch at Hong Kong, has been taking exposure with PNB as a country party under various LoUs issued through authenticated SWIFT message," Allahabad Bank had said in a filing.
