Bank of America US$1m-plus RTP transactions jump 351% as corporate payment volume rises 48%

Bank of America’s corporate clients increased their use of real-time payments sharply during the first seven months of 2026, with overall RTP transaction volume rising 48% year on year and the number of transactions above US$1m jumping 351%.

The figures provide a measurable indication that real-time payment rails are moving beyond smaller or urgent payments into corporate treasury and liquidity-management activity.
Bank of America said clients are increasingly using the RTP network for intercompany transfers, cash concentration, supplier and affiliate payments, centralised disbursements and transfers between accounts held at different financial institutions.

The shift follows a substantial increase in the network’s maximum individual transaction size. The RTP limit was raised from US$1m to US$10m in February 2025, opening the infrastructure to larger business-to-business payments and corporate cash movements.

The 351% figure refers specifically to growth in the number of corporate transactions above US$1m, rather than a 351% increase in their aggregate dollar value. Bank of America did not disclose the underlying transaction count or total value handled through the network.

For corporate treasurers, the attraction is not limited to settlement speed. RTP is available around the clock, allowing companies to reposition liquidity outside conventional banking hours and move cash between subsidiaries or accounts during month-end and quarter-end periods.

That can reduce the amount of precautionary liquidity held in individual accounts because treasury teams have greater flexibility to move funds when obligations arise. The extent of any actual working-capital saving will depend on each company’s treasury structure and the availability of receiving institutions on the network.

The data also shows how higher payment limits can change the function of real-time infrastructure. A rail initially associated with lower-value transactions can increasingly support cash concentration and liquidity positioning once individual payments can reach US$10m.

Bank of America has not disclosed how much of the 48% overall increase came specifically from supplier payments, intercompany transfers or cash-concentration activity.
