SoFi Launches Big Business Banking - First US National Bank to Merge Fiat and Crypto

SoFi Technologies on April 2 unveiled Big Business Banking - the first banking platform in the U.S. that allows companies to manage dollars and cryptocurrencies within a single regulated account. At the heart of the service is SoFiUSD - a stablecoin backed 1:1 by cash equivalents held at the Federal Reserve and issued on the Solana blockchain.

How Big Business Banking works

The platform replaces the patchwork of separate banks, stablecoin issuers, and custodians that crypto companies typically rely on. Companies get a single account with 24/7 dollar deposits, instant conversion to SoFiUSD, and fund transfers via blockchain networks. Converting back to dollars is equally fast, no waiting for bank wires to clear.

In practice, a trading firm can deposit dollars at SoFi, convert them to SoFiUSD, and instantly deploy capital into markets. Settlements that traditionally took one to three business days are compressed to seconds. The platform operates 24/7/365, which is critical for crypto markets that never close.

SoFiUSD: a stablecoin from a regulated bank

Unlike most stablecoins issued by companies outside the banking system, SoFiUSD is tied directly to a regulated national bank's balance sheet. Reserves are held internally as cash equivalents at the Fed, ensuring full 1:1 backing.

This is a essential distinction from USDT, whose reserves are held by Tether Limited outside the banking system, and USDC from Circle, which, while regulated, does not hold a banking license. SoFi is currently the only U.S. national bank directly issuing a stablecoin on a public blockchain.

Partners: from market makers to Mastercard

The early partner roster includes the biggest names in crypto infrastructure. Cumberland, Wintermute, and B2C2 are leading market makers that will provide liquidity. Galaxy and Bullish bring institutional investment and exchange capabilities. BitGo and Fireblocks handle custody. Jupiter adds a bridge to Solana's DeFi ecosystem.

The participation of Mastercard and Mesh Payments is particularly telling, traditional financial giants that see stablecoins as infrastructure for the next generation of payments. This confirms the accelerating trend of traditional finance merging with blockchain technology throughout 2026.

Why this matters for the market

The Big Business Banking launch comes because of active Congressional work on stablecoin legislation. The GENIUS Act is approaching final approval, while the CLARITY Act has a 63% chance of passing in 2026 according to Polymarket data. Regulatory clarity makes bank entry into the crypto space less risky.

For the broader crypto market, the emergence of a bank-issued stablecoin means new competition for USDT and USDC. If SoFi's model proves successful, other national banks may follow suit, potentially redistributing the $160 billion stablecoin market in favor of regulated bank issuers.
