Overnight deposits XT73 for the following reason: In overnight market transactions lenders lend funds only overnight, i.e. the borrower must repay the borrowed funds plus interest at the start of the business the next day.

Typically this type of transactions occur in the morning after the start of the business day and are finalised the next morning. For that period in time, i.e. overnight, the lender does not have access to the borrowed funds, so that it should be XT73 as categorisation.
