Singapore Gulf Bank

Singapore Gulf Bank (SGB) is a fully licensed conventional wholesale bank regulated by the Central Bank of Bahrain (CBB) that positions itself as a single institution spanning both traditional and digital finance. Its core promise—"one bank, all of finance"—is realized through a platform that lets corporate clients and high-net-worth individuals manage fiat accounts, execute cross-border payments, and interact with blockchain-native assets without leaving the banking environment.

Background and Ownership

SGB was founded through a partnership between Whampoa Group (Singapore) and Mumtalakat, Bahrain's sovereign wealth fund. Amy Lee, niece of Singapore's founding Prime Minister Lee Kuan Yew, chairs the Global Advisory Board. Headquartered at the Bahrain World Trade Center in Manama, the bank holds a CBB licence as a conventional wholesale bank, giving it the regulatory standing to serve institutional and high-net-worth clients across the Gulf Cooperation Council region and beyond. SGB Net, its internal clearing infrastructure, processes over $2 billion in monthly fiat transaction volume.

Solana Integration: Stablecoin Mint and Redeem

SGB's most prominent Solana-focused offering is its stablecoin mint and redeem service, launched at Solana Breakpoint 2025 in Abu Dhabi and made fully live in April 2026. The service allows verified corporate clients to convert fiat currency directly into USDC on-chain and redeem it back to fiat from within their bank accounts, with settlement happening in real time around the clock.

The mechanism works by integrating directly into SGB Net, the bank's proprietary clearing system. Clients do not need to interact with third-party crypto exchanges or custodians to complete the conversion; the entire flow—from bank debit to on-chain USDC delivery—runs inside the regulated banking environment. This positions SGB as one of the first fully licensed banks to embed stablecoin rails directly inside its core clearing infrastructure.

Solana is the bank's preferred network for this service. SGB waives both gas fees and bank fees for all USDC minting and redemption on Solana during its promotional launch period, with volume-based rewards continuing after that phase concludes. The bank cited Solana's transaction speed and low base costs as the primary reasons for the preferential treatment, noting that Solana settlements complete in seconds at a fraction of the cost of traditional correspondent banking.

The minimum transaction threshold is $100,000, reflecting a deliberate focus on institutional flows—treasury operations, cross-border payables, and liquidity management—rather than retail use cases.

Multi-Chain Platform

While Solana is the flagship network for fee-free access, SGB's stablecoin platform also supports Ethereum, Base, Arbitrum, and Avalanche. USDC is the first stablecoin available at launch, with USDT, USDe (Ethena's yield-bearing stablecoin), and USDG (Global Dollar) planned for future addition. The multi-chain design reflects SGB's aim to serve institutional counterparties wherever their liquidity already sits, rather than requiring them to migrate entirely to a single network.

Infrastructure and Partnerships

SGB has assembled a set of institutional-grade infrastructure partners to underpin the service:

• Fireblocks: Provides custody and wallet infrastructure using multi-party computation (MPC) cryptography, giving corporate clients auditable, insured custody for on-chain assets held within the banking environment.
• Standard Chartered: A strategic banking partnership announced in 2026 gives SGB access to Standard Chartered's global correspondent banking and clearing network, strengthening multi-currency cross-border settlement flows for clients operating across emerging digital asset markets.
• BNY Mellon: SGB joined BNY's correspondent banking network in April 2026, enhancing its US dollar clearing capacity and adding a tier-one financial counterparty to its settlement chain.
• BIT Platform: SGB's personal banking offering integrates with BIT to give clients direct access to US equity markets alongside their cash and crypto holdings.

Personal and Business Banking

Beyond the institutional stablecoin rails, SGB operates across two main customer segments.

For personal banking, SGB offers remote account onboarding, a mobile app (available on iOS, Android, and Huawei AppGallery), multi-currency accounts, and integrated access to digital assets through exchange partnerships. As of July 2026, personal banking demand is strong enough that the bank is managing a waitlist and prioritising applicants with cross-border banking needs and an opening deposit of at least $10,000.

For business banking, SGB provides liquidity management, multi-currency clearing, and cross-border settlement services, now enhanced by the Standard Chartered and BNY Mellon relationships. The institutional stablecoin service is the primary on-chain product for this segment.

Fit in the Solana Ecosystem

SGB represents a relatively rare entry point into Solana from traditional, regulated banking. Most Solana stablecoin volume historically flowed through decentralised protocols or crypto-native exchanges; SGB's model pushes fiat-to-USDC conversion upstream, into the banking layer itself. By making Solana the zero-fee default for institutional minting and redemption, SGB adds a regulated, KYC/AML-compliant demand channel for USDC on Solana—one that could scale meaningfully given SGB Net's existing $2 billion monthly fiat throughput.

The bank's fee waiver and volume incentive programme during the launch phase is structured to drive Solana-native transaction volume as institutional clients build familiarity with the network. Longer term, the planned addition of USDT and USDe would bring Ethena's yield-bearing stablecoin into SGB's banking rails, adding another layer of DeFi-adjacent infrastructure accessible within a fully regulated wrapper.

As of July 2026, SGB is actively operating, with personal account demand described as strong, institutional stablecoin rails live on Solana and four other networks, and a correspondent banking infrastructure anchored by Standard Chartered and BNY Mellon.
