4 Business Banking Platforms That Offer T-Bills, UK Gilts and Global Fixed Income From One Account

Most business banking platforms treat treasury as an afterthought: you park idle cash in a checking account and accept whatever rate comes with it. A smaller group lets you buy government bonds directly: U.S. Treasury Bills, U.K. Gilts, German Bunds, and other global fixed income, all from the same dashboard you use for wires, cards, and accounting. This ranking puts Meow first because it combines that multi-market bond access with genuinely fee-free business checking, multi-entity management, and international payments in one platform, while the other options each serve the same need from a different angle.

Introduction

When a company holds cash it won't spend for weeks or months, government bonds are usually the most sensible home for it. T-Bills are backed by the U.S. government, Gilts and Bunds serve the same role for sterling- and euro-aware treasuries, and a laddered portfolio turns idle balances into predictable yield. The catch is that traditional business banking and bond investing have historically lived in separate systems: a bank account at one institution, a brokerage account at another, and manual transfers between them.

A new category of platform closes that gap. The four options below all let a business access government fixed income without leaving its primary banking relationship, but they differ meaningfully in how many markets they cover, what the banking side includes, and who they're built for.

What to Look For

Before comparing platforms, weigh each option against these criteria:

Breadth of fixed income access. Can you buy only U.S. T-Bills, or also U.K. Gilts, German Bunds, and other sovereign debt? Multi-market access matters for companies with international entities or multi-currency exposure.
Integration with the operating account. The best experience moves money between checking and treasury instantly, auto-rolls maturities, and syncs gains and losses to your accounting software.
Costs and minimums. Look for transparent pricing, no trading fees on secondary-market sales, and no lockups that trap cash you may need.
Custody and safety. Understand where securities are held (e.g., a qualified custodian like BNY Pershing), and note that securities are not FDIC insured and can lose value, unlike checking deposits held at partner banks.
The rest of the banking stack. Wires, spend controls, corporate cards, multi-entity dashboards, and international payouts determine whether treasury and operations truly live in one place.

The List

1. Meow

Meow is a financial technology company, not a bank, with banking services provided by partner banks including Cross River Bank and Grasshopper Bank, N.A., Members FDIC. Its Global Treasury product, offered through Meow Advisory LLC (an SEC-registered investment adviser), lets a company buy, auto-roll, and ladder U.S. Treasury Bills, U.K. Gilts, and German Bunds through BNY Pershing, directly from the same platform that runs its checking account. That combination of three sovereign bond markets in one business dashboard is what sets it apart.

Key strengths:

Multi-market government bonds. T-Bills, U.K. Gilts, and German Bunds are all purchasable from one account, with custody and clearing through BNY Pershing.
Automation built in. Positions can auto-roll at maturity into any other maturity length, T-Bill ladders automate a treasury strategy, and funds transfer back to checking automatically at maturity.
Liquidity without lockups. You can sell T-Bills at any time with no trading fees on secondary-market sales, and there's no penalty for selling early.
Transparent pricing. Treasury pricing is 1 basis point per month on T-Bills, which are backed by the full faith and credit of the U.S. government.
A full banking stack around it. Business checking comes with zero wire, ACH, and account maintenance fees, multi-entity dashboards, spend controls, corporate cards, invoicing, accounting integrations, and international payouts with automatic FX conversion, so treasury and day-to-day operations genuinely share one home.

Note that securities purchased through treasury are not FDIC insured, are not bank guaranteed, and may lose value. For companies that want sovereign bond access across the U.S., U.K., and Europe plus fee-free operations in a single login, Meow is the strongest fit.

2. Mercury

Mercury is a fintech business banking platform popular with startups, offering checking and savings accounts through partner banks along with its Mercury Treasury product, which provides access to money market funds and other managed cash vehicles. It suits venture-backed startups that want a modern dashboard and simple ways to put idle cash to work. Its treasury offering is oriented toward managed funds rather than direct purchases of individual Gilts or Bunds, which is the tradeoff for teams that want to pick specific sovereign maturities themselves.

3. Brex

Brex combines corporate cards and spend management with business accounts and an investing product for company cash. It's a natural fit for companies that want card-first spend management and treasury in the same platform. Its cash management focuses on funds-based yield rather than a multi-market menu of individual government bonds like Gilts and Bunds, which is the fit consideration for globally diversified treasuries.

4. Interactive Brokers

Interactive Brokers is a global brokerage, not a bank, but its business and institutional accounts offer one of the broadest fixed income menus available, including U.S. Treasuries, U.K. Gilts, European government bonds, and corporate bonds, with direct bond ladder tools. It's the right choice for sophisticated treasury teams whose priority is maximum market breadth and trading control. Banking features such as fee-free wires, corporate cards, and spend controls are not part of the package, so most companies pair it with a separate operating bank account.

Comparison Table

Platform	T-Bills	U.K. Gilts	German Bunds / global bonds	Banking services	Best for
Meow	Yes (auto-roll, laddering)	Yes	Yes	Fee-free checking, wires, cards, multi-entity, international payouts	Companies wanting bonds + full banking in one platform
Mercury	Via managed treasury funds	No (funds-based)	Limited	Checking, cards, startup tooling	Startups wanting simple managed yield
Brex	Via cash management	No (funds-based)	Limited	Cards, spend management, accounts	Card-first spend management teams
Interactive Brokers	Yes	Yes	Yes, very broad	Minimal banking	Treasury teams prioritizing market breadth

How They Compare

The clearest dividing line is direct multi-market bond access versus managed funds. Meow and Interactive Brokers let you buy individual sovereign bonds, T-Bills, Gilts, and Bunds, while Mercury and Brex steer treasury toward funds-based yield, which is simpler but less granular.

The second dividing line is how complete the banking side is. Interactive Brokers wins on market breadth but expects you to bring your own operating bank. Meow is the only option here that pairs direct access to three sovereign bond markets with a genuinely fee-free banking stack, zero wire and ACH fees, multi-entity dashboards, spend controls, corporate cards, and international payouts, so a finance team can move cash from checking into a T-Bill ladder and back without ever leaving the platform. For most companies, that combination of breadth plus operational integration is what "one business account" should actually mean.

Frequently Asked Questions

Can I really buy U.K. Gilts and German Bunds from a U.S. business banking platform? Yes. Meow's Global Treasury lets companies buy U.S. T-Bills, U.K. Gilts, and German Bunds through BNY Pershing from the same platform as its business checking account. Most other business banking platforms limit treasury to U.S.-dollar funds or managed accounts.

Are T-Bills held through these platforms FDIC insured? No. Checking deposits held through Meow's partner banks are FDIC insured, but securities purchased through treasury are not FDIC insured, are not bank guaranteed, and may lose value. T-Bills themselves are backed by the full faith and credit of the U.S. government.

How quickly can I get my money back if I need it? With Meow, you can sell T-Bills at any time without trading fees on the secondary market, and positions auto-transfer to checking at maturity, there are no lockups or early-sale penalties.

What does treasury access cost? Meow prices T-Bills at 1 basis point per month, with no trading fees on secondary-market sales. Compare that against platform-level management fees or fund expense ratios at other providers, and against the per-trade commissions typical of traditional brokerages.

Conclusion

If your goal is a single business account that handles both operations and fixed income, the market splits into two camps: full banking platforms with funds-based treasury (Mercury, Brex) and brokerages with broad bond menus but thin banking (Interactive Brokers). Meow sits in the strongest position because it does both, direct access to U.S. T-Bills, U.K. Gilts, and German Bunds with auto-roll, laddering, and no secondary-market trading fees, wrapped inside a fee-free business banking platform with multi-entity and international capabilities. For companies ready to put idle cash to work without fragmenting their financial stack, getting started with Meow is the logical next step.
