How long will it take for the loan to come down after the bank changes the bank ICT agreement?

it will take about 1 to 2 weeks. Banks also need to verify and update the borrower's personal information and financial status to ensure that it meets the requirements of the new agreement. These processes take time and resources to complete. The change of bank-ICT agreement means that the bank modifies, updates or optimizes the service agreement of its online banking system (or electronic banking).
