KB Kookmin Bank taps BNY Pay-to-Wallet for cross-border digital wallet payments

One of South Korea’s largest banks is wiring itself directly into digital wallets. KB Kookmin Bank has signed a strategic agreement with BNY covering cross-border digital asset payments and remittances, becoming one of the first banks in Asia Pacific to use the custody giant’s newly launched Pay-to-Wallet capability.

BNY confirmed on Sept. 28 that Kookmin Bank is among the initial users of Pay-to-Wallet, a service that lets banks send cross-border payments from customer bank accounts directly to participating retail digital wallets. The memorandum of understanding was signed during Sibos 2026 at the Miami Beach Convention Center in Florida, on the same day BNY launched the capability.

The agreement covers cooperation in digital payments, digital assets, and cross-border remittance services, with BNY’s global payment network forming part of the planned infrastructure. For Kookmin Bank customers, the first stated use case centers on overseas remittances, including services for foreign residents and international students. The bank plans to combine its foreign-exchange capabilities with BNY’s payment network and Pay-to-Wallet infrastructure.

## Old rails, new destination

Pay-to-Wallet’s design is deliberately conservative. The service uses existing SWIFT messages, correspondent banking arrangements, and ISO 20022 messaging infrastructure to reach supported wallets, combined with BNY’s U.S. dollar clearing network and round-the-clock processing for approved payment markets and corridors. In other words, the payment rail is not new; the final destination is.

That approach gives participating banks a route from conventional accounts to retail digital wallets without requiring each lender to build separate integrations with individual wallet providers. BNY lists potential applications including person-to-person cross-border payments, tax refunds, insurance payouts, and pension distributions. The bank has not publicly identified every wallet provider or corridor supported in the initial Kookmin deployment.

Raphael Baik, head of Kookmin Bank’s foreign exchange business division, said customers increasingly want payment options that match the way recipients prefer to receive money. A Pay-to-Wallet capability can help the bank broaden access to digital wallet payments in a more efficient way, Baik said.

Fabian Khoshbakht, BNY’s head of global payments and trade for Asia Pacific, framed the product as an answer to integration fatigue. Banks need payment capabilities they can deploy without having to build layers of integration with wallet providers, he said.

One caveat deserves emphasis: although the Kookmin agreement covers digital assets, BNY’s Pay-to-Wallet should not be described as a cryptocurrency transfer product. BNY has not said the initial service settles payments with stablecoins or other cryptocurrencies. The service sends money from bank accounts to participating retail wallets through established infrastructure, and nothing in the announcement changes that.

## Why Asia Pacific first

BNY plans to begin with selected Asia-Pacific participants before extending Pay-to-Wallet into more markets, and the commercial logic is easy to see. Digital wallets already account for 50 percent of point-of-sale transactions in Asia Pacific, BNY said, and the bank projects that share to exceed 60 percent by 2027. For a payments provider, the region’s wallet density makes it the obvious proving ground.

BNY brings considerable weight to the effort. The institution had 62.6 trillion USD in assets under custody or administration and 2.2 trillion USD under management as of June 30, and says it serves nearly all of the world’s top 100 banks.

## Kookmin’s blockchain groundwork

The agreement also fits a pattern for Kookmin Bank, which spent 2026 building out digital-asset payment rails. The lender previously launched blockchain-based corporate cross-border payments through J.P. Morgan’s Kinexys network, operating across ten countries successfully. The BNY deal extends that trajectory from corporate treasury flows toward retail and remittance channels, using infrastructure that does not require the bank to operate crypto wallets of its own.

For Korean regulators and banking watchers, the significance is less about cryptocurrency adoption than about plumbing. Kookmin is signaling that digital wallets, not just bank accounts, are now treated as first-class destinations for cross-border money. As wallet usage across Asia Pacific keeps climbing, the banks that can reach those wallets without bespoke integrations are the ones likely to keep the remittance flow.

The Sibos timing also matters. The annual conference is where correspondent banking’s biggest operators reveal their product roadmaps, and BNY chose the stage to put wallet connectivity at the center of its payments pitch. That a top Korean bank signed on as a launch user signals demand among traditional lenders for wallet reach, even among institutions with no public interest in crypto settlement. Expect the corridor list, the supported wallet providers, and the first live remittance volumes to be the details markets watch next.
