Kast launches stablecoin business accounts with up to 8% APY
Sep 02, 2026
Kast has launched a stablecoin-based business platform offering accounts, cards, and transfers in more than 20 currencies, with returns of up to 8% APY across over 170 countries.
Kast Business combines payments with stablecoin balances
The platform brings several functions normally offered by separate providers into one dashboard. Along with receiving and sending funds, business owners can create virtual cards and assign them to individual team members or recurring expenses.
The 8% APY comes with product and jurisdiction limits
Kast advertises returns of up to 8% APY on idle business balances. The company says the return comes from short-term U.S. Treasuries and stablecoin yield, but the maximum rate should not be treated as a fixed return available to every customer.
U.S. rules place stablecoin rewards under scrutiny
For U.S. businesses, the yield feature arrives while regulators and lawmakers continue to examine how stablecoin rewards should be treated.
The GENIUS Act created a federal framework for payment stablecoins and prevents payment stablecoin issuers from paying interest or yield solely for holding their tokens. The restriction does not automatically settle how a separate fintech platform may offer rewards or returns through an account, Treasury product, or another investment arrangement.
Kast targets up to 5,000 active businesses in 2026
Kast launched the business product after closing an $80 million Series A funding round in March at a reported valuation of $600 million.
The company said it would direct the capital toward product development, licensing, and expansion in North America, Latin America, and the Middle East. Kast claims more than 1 million users and plans to bring between 1,000 and 5,000 active companies onto KAST Business by the end of 2026.
Before the business-platform rollout, Kast appointed former U.S. Securities and Exchange Commission senior adviser Stephanie Allen as head of corporate and policy communications. The April appointment placed Allen in charge of the company’s engagement with policymakers, industry groups and media as Kast expanded its stablecoin services in North America and Latin America.
