Sage Capital Management has expanded its institutional digital-asset offering with the launch of a private banking service, positioning the move as part of a broader, platform-centric strategy to deliver integrated financial infrastructure for digital assets.
At the centre of the proposition is the Sage platform, which the firm describes as a unified operating system designed to connect banking, trading, custody, liquidity and capital within a single regulated framework. The aim is to address persistent fragmentation in institutional digital-asset markets, where critical services are typically distributed across multiple providers, platforms and counterparties.“What you see in the market today is banking, brokerage, liquidity and credit operating as separate silos,” says Nathan Sage, CEO of Sage Capital Management, in conversation with TradingTech Insight. “There are good companies in each, but they don’t connect well. The result is friction, fragmentation and inefficiency. This is still a young market, and the infrastructure simply hasn’t been designed to work together seamlessly. Our view is that by connecting all of these components into a single operating system, under one regulated counterparty, life becomes much easier for institutional clients. Costs come down, capital is used more efficiently, and risk is reduced.”
Platform-first approach to institutional digital assets
Institutional participation in digital assets has continued to grow, but the underlying operating model has remained highly disaggregated, according to Sage, creating operational complexity and increasing settlement and counterparty risk.
Sage Capital Management is positioning its platform as a control layer that brings these components together in a single environment. “The real value comes when everything is connected seamlessly,” says Sage. “Through the platform, clients can see banking, wallets, custody and trading in one place, via both GUI and API. That’s why we use the term ‘operating system’ – it accurately reflects what we’re building.”
The platform underpins Sage Capital Management’s unified access to spot, derivatives and OTC digital-asset markets through a single regulated counterparty. Liquidity is aggregated across more than 40 global venues, allowing institutional clients to access multiple markets without maintaining direct exchange relationships or pre-funded balances across multiple venues.
This model is intended to simplify onboarding, centralise settlement and reduce the operational overhead associated with managing fragmented trading infrastructure.
Capital provision embedded into the platform
Capital provision is delivered as an integrated component of the platform rather than as a standalone service. The company’s capital engine supports portfolio margining, institutional credit and structured financing, with collateral deployed centrally and reused across trading and financing activities.
“We’ve designed a model that uses multiple credit providers rather than a single balance sheet, allowing us to scale as the market grows,” notes Sage, adding that this approach is a way to improve capital efficiency while supporting institutional scalability as digital-asset trading volumes increase.
The newly launched private banking service is positioned as an extension of the platform rather than a standalone offering. Institutional clients are provided with named, multi-currency accounts under their own legal entities, connected to major payment rails including UK Faster Payments, SEPA and SWIFT, with access to more than 140 currencies.The service supports payments, foreign exchange and the movement of funds between fiat and digital-asset markets, and includes physical and virtual corporate debit cards for operational use.
“We use our expertise and our compliance capability to act on behalf of clients,” says Sage. “We sit between them and tier-one banks, ensuring onboarding works properly, payments flow smoothly, and friction is removed. In that sense, we’re not competing with other providers directly. We’re competing with friction.”
Proprietary technology as a control layer
All services are delivered through the Sage platform, which brings together banking, custody, wallets, execution, margining, risk management and transaction cost analysis. The platform supports multi-venue and multi-product trading, aggregated order books and configurable workspaces.
“The Sage platform offers instant settlement across multiple accounts, portfolio margining using multiple asset types, deep integration across banking, custody and wallets, and first-pass institutional-grade reporting,” says Sage. “It was designed by senior traders from major banks, so it’s highly usable. Teams across trading, risk, operations and settlement can all access the same system with role-based views, which breaks down internal silos and improves visibility and control.”
The launch reflects a broader industry shift towards consolidation of digital-asset infrastructure as institutional firms seek more resilient, scalable and predictable operating models. As regulatory expectations increase and market participation deepens, integrated platforms are increasingly viewed as a prerequisite for institutional adoption.
By leading with its platform and positioning private banking as one component of a wider operating system, Sage Capital Management is framing itself as an infrastructure provider rather than a point solution within the institutional digital-asset ecosystem.
