Capital B to Launch Bitcoin-Backed Credit Product for European Investors

Capital B is moving beyond simple Bitcoin accumulation and into Bitcoin-backed credit, aiming to build a product for European investors that could pay double-digit yields while using its BTC treasury as collateral.

• Capital B is building a bitcoin-backed credit product for European investors
• The product would be backed by its 3,139 BTC treasury
• The goal is double-digit yields with relatively low volatility
• Strategy’s STRC and Strive’s SATA are being used as loose models
• Shareholders are set to vote on a massive funding plan on June 17

Capital B, the Paris-listed company formerly known as The Blockchain Group, is trying to turn its Bitcoin treasury into more than a pile of hard money on the balance sheet. The company is working on a bitcoin-backed credit product for European investors, a move that signals just how far corporate Bitcoin finance is starting to stretch beyond simple “buy and hold” treasury strategy.

The basic idea is straightforward. Capital B wants to use its 3,139 BTC stack as backing for a digital credit instrument that could offer yield to investors while keeping volatility below double digits. In plain English: it’s a Bitcoin-collateralized income product, not just another spot BTC wrapper. That may sound elegant on a slide deck. In real markets, of course, the devil tends to show up wearing a custody badge and asking awkward questions about risk.

Alexandre Laizet, a Capital B board director, outlined the plan at BTC Prague. The company described the concept as a digital credit instrument for European investors, modeled loosely on products such as Strategy’s STRC and Strive’s SATA. Those U.S.-linked structures have helped fuel the growing idea that Bitcoin treasury companies can do more than stack sats; they can also build financing products on top of them.

That’s the bullish version. The cautious version is simpler: once you start packaging Bitcoin into yield products, you are no longer just riding BTC’s upside. You are also inheriting all the ways structured finance can go sideways. Bitcoin may be the collateral, but collateral never cancels risk. It just changes the flavor of it.

Capital B says the product is intended to deliver double-digit yields while keeping volatility below double-digit levels. That is an ambitious target, and maybe a little too polished for comfort. Investors love yield. They also love pretending yield appears out of thin air. It doesn’t. Someone, somewhere, is always taking the other side of that trade.

The company is at least acknowledging that reality. Capital B says investors need to consider Bitcoin price declines, execution risk, custody risk, and counterparty exposure. Those are not decorative footnotes. They are the whole game.

Bitcoin price declines matter because BTC-backed products can come under pressure fast if the market dumps. Execution risk means the company might not be able to launch or operate the structure as planned. Custody risk is the danger that the Bitcoin securing the product is mishandled, lost, or compromised. Counterparty exposure means another party in the structure could fail to perform, leaving investors holding the bag. In tradfi, that’s called “risk management.” In crypto, people often call it “finding out.”

The timing is important. Capital B recently asked shareholders to approve up to €5 billion in equity issuance and up to €116 billion in credit instruments. That is a staggering amount of authorized financing power, even if not all of it is expected to be used anytime soon. Shareholders are scheduled to vote on the proposal at the June 17 combined general meeting.

If approved, the financing framework would give Capital B serious room to expand its Bitcoin treasury strategy and experiment with new products. That’s where the company’s broader ambition starts to matter. Capital B says investor interest in digital credit products is now ten times higher than last year, suggesting there may be real demand for Bitcoin-backed yield products among European investors who want BTC exposure without simply buying and holding spot.

That demand is easy to understand. Not every investor wants to self-custody Bitcoin, stare at price charts all day, or wait around for the next cycle with nothing but conviction and cold storage. Some want income. Some want capital-efficient exposure. Some want something that feels a little more familiar than pure spot BTC. The catch is that “familiar” is not the same thing as “safe.”

Capital B has already attracted attention from serious Bitcoin and finance names. Earlier this year, the company completed a €15.2 million private placement backed by Blockstream CEO Adam Back and Paris-based asset manager TOBAM. That funding helped Capital B buy 192 BTC, followed by a later purchase of 4 BTC. Those are not headline-grabbing treasury numbers, but they show the company can attract capital from investors who understand the Bitcoin thesis rather than just chasing whatever shiny token narrative is trending this week.

The company’s broader Bitcoin plan is far more aggressive than its current stack might suggest. Capital B wants to accumulate 1% of Bitcoin’s total supply by 2033 and is targeting 15,000 BTC by the end of 2027. That is not cautious corporate housekeeping. That is a public company acting like a Bitcoin accumulation machine with aspirations to become a financial platform, not merely a holder of reserve assets.

And that is the real strategic shift here. Bitcoin treasury companies are starting to evolve from passive holders into active builders of financial products. If Bitcoin is treated as sound collateral and a long-duration reserve asset, then it can theoretically support lending, credit, and structured yield products. That could be useful, especially in Europe, where regulated investors and institutions often want something more sophisticated than simple spot exposure.

But there’s a line between useful innovation and financial cosplay. Wrap enough complexity around Bitcoin and you can end up recreating the same old leverage games that blew up plenty of “safe” products long before crypto came along. A Bitcoin-backed credit product can be well-designed, transparent, and disciplined. It can also become a yield machine that looks clever until volatility shows up and kicks the table over.

That’s why Capital B’s comparison points matter. Strategy’s STRC and Strive’s SATA suggest the company is borrowing from a growing playbook of BTC-linked financing structures. The concept is gaining traction because it offers a middle ground between pure Bitcoin ownership and traditional fixed income. But the mechanics have to be sound. Bitcoin is not a magic shield against bad structuring, sloppy custody, or overconfidence dressed up as financial engineering.

Capital B’s rebrand from The Blockchain Group to Capital B in July 2025 also fits the company’s clearer identity as a Bitcoin treasury company rather than a vague blockchain brand chasing buzzwords. That may sound cosmetic, but it matters. “Blockchain” was the old corporate cope. “Bitcoin treasury” is at least honest about what the company is trying to do: accumulate BTC, use BTC, and build around BTC.

Whether this turns into a real European Bitcoin finance niche or just another over-engineered yield product remains to be seen. No launch date has been announced yet, which means the idea is still in development. But the direction is hard to ignore. More companies are realizing that Bitcoin can be more than a treasury line item. It can also be the collateral base for new capital markets products.

That’s exciting, and it should be. Bitcoin was always going to do more than sit in cold storage for 100 years while legacy finance slowly caught up. At the same time, a lot of “innovation” in finance is just leverage in a nicer suit. Capital B may well be building something genuinely useful for European investors. It may also be testing just how much complexity the market is willing to swallow before the yield story starts smelling like a dressed-up risk transfer scheme. Both things can be true.
