Welcome back to Bitesize Payments Digital.

Today I'm going to cover a topic that one way or another is front and centre in Europe in particular. But frankly it’s a global issue. My aim here isn’t to be political but to try and explain.

Today I’m covering: The Sovereignty Container Breaks.

Here we go.

THE TAP

You’re in a café in Paris. You tap your phone to pay. Four euros fifty disappears from your account. The barista nods. Transaction complete.

Do you know what currency actually moved?

Do you care?

Your phone showed “four fifty” but behind that interface, something happened. Maybe your UK bank converted pounds to euros. Maybe it went through Visa’s network. Maybe it touched three different currencies in milliseconds. Maybe it was a stablecoin that never touched a traditional bank at all.

You have no idea. And it doesn’t matter. It just worked.

The number went down. The coffee appeared. That’s all you needed to know.

This is where currency stops being a brand you relate to and starts being invisible infrastructure. Like you don’t know what email protocol your message used. Like you don’t care what server Netflix runs on.

It just works.

And when currency becomes infrastructure people don’t think about, something fundamental shifts in how governments relate to their citizens.

THE MONOPOLY NOBODY QUESTIONED

For thousands of years, governments controlled money.

Not because they were particularly smart about it. Not because citizens voted for it. Not even because it was policy.

Because physics made it inevitable.

The King minted coins because you couldn’t. Setting up a mint required massive capital, technical expertise, and the ability to defend it. You didn’t have any of those things. The King did.

Borders contained currency because gold doesn’t easily cross oceans. Moving physical value was dangerous, slow, and expensive. If you wanted to trade internationally, you needed intermediaries, letters of credit, trusted agents. The infrastructure of international payments was inherently governmental.

Banks needed charters because vaults are physical. You can’t just start a bank in your garage. You need a building, security, insurance, integration with the payment system. All of which required government permission and oversight.

Physical money flowed through physical channels that governments built and controlled. Not by choice — by necessity.

Governments never had to compete for your trust. Never had to earn your business. Never had to justify why you should use their currency instead of something else.

They just… were.

Like the local telephone company before mobile phones existed. Like the post office before email. Like taxis before ride-sharing apps.

The monopoly wasn’t a policy decision. It was physics. And everyone assumed it was permanent.

WHAT THE MONOPOLY ACTUALLY GAVE THEM

That monopoly wasn’t just about pride or power. It gave governments specific, essential capabilities.

Visibility. They could see economic flows within their territory. Every payment through a bank, every wire transfer, every card transaction — visible. Trackable. This wasn’t surveillance for its own sake. You can’t tax what you can’t see. You can’t stop money laundering if flows are invisible. You can’t enforce sanctions if you don’t know where money is going.

Control. They could freeze accounts. Block transactions. Prevent money from flowing to sanctioned entities. Stop criminal enterprises from accessing the financial system. Not perfectly — cash always leaked — but well enough to make law enforcement possible.

Monetary policy. They could control the money supply, set interest rates, manage inflation. When a crisis hit, they could inject liquidity. When the economy overheated, they could tighten. Not always successfully, but at least they had tools.

Seigniorage. They profited from issuing currency. When you print money that costs pennies to produce and people treat it as worth pounds or dollars, that’s real value captured by the state. Not a huge revenue source, but not nothing either.

Brand. The pound. The dollar. The euro. These weren’t just currencies — they were symbols of national strength. A strong currency meant a strong country. Exchange rates were scoreboards. “The almighty dollar” wasn’t just a phrase — it represented American economic dominance. The euro was a branding exercise, creating a currency to rival the dollar and give Europe weight on the global stage.

Here’s something interesting: even in the Eurozone, where countries gave up their own currencies, they kept their central banks. The Banque de France. The Bundesbank. Banca d’Italia. Banco de España.

Why? The European Central Bank sets monetary policy for everyone. What do national central banks actually do?

They maintain visibility and control over their piece of the system. Even without their own currency, each government needs to see flows within their economy, maintain connections to their banking system, retain some operational levers.

Because that’s what sovereignty requires: not just a currency brand, but operational control over economic activity within your borders.

THEN UBER ARRIVED

Here’s an analogy.

Imagine you controlled all the taxis in London. You licensed the drivers. You set the fares. You determined who could pick up passengers and where. You built the entire infrastructure — the taxi ranks, the radio dispatch, the payment systems.

You were the gatekeeper. Nothing happened without going through your system.

Then Uber arrives.

Suddenly drivers don’t need your licence — they’re “ride-sharing.” They don’t use your taxi ranks — GPS gets them anywhere. They don’t follow your pricing — algorithms adjust dynamically. They don’t use your infrastructure — they built their own app, their own payment system.

Your regulations? They technically don’t apply because Uber drivers aren’t “taxis.”

You still control taxis. You can still licence black cabs. Your rules still govern traditional taxi services.

But who cares?

Most people are using Uber. Your brand — the iconic black cab — is now a niche product. Your regulations govern an increasingly irrelevant part of the market.

You’re still in charge of taxis. But taxis aren’t where the action is anymore.

This is the sovereignty problem with digital money.

Governments still control national currencies. They still regulate banks. They still oversee traditional payment rails like ACH, SEPA, wire transfers.

But what if that’s not where value flows anymore?

Cryptocurrency doesn’t need banking licences. Stablecoins don’t touch national payment systems. Cross-border payments can happen peer-to-peer through protocols, bypassing correspondent banks entirely. Value moves through channels governments didn’t build and don’t control.

The question isn’t whether governments lose their monopoly. They already lost it. The question is: what happens when they realise it?

WHAT BREAKS

When digital value can flow outside traditional systems, several things that governments took for granted start breaking.

Visibility breaks. You can’t see transactions on decentralised networks the way you could see wire transfers through SWIFT. Someone in London can hold value and move it internationally without touching a single regulated institution. Not because they’re doing anything illegal — just because the technology allows it. But if you can’t see flows, how do you tax them? How do you enforce sanctions? How do you even know what’s happening in your economy?

Control breaks. You can’t freeze a wallet you don’t control. You can’t block a transaction on a decentralised protocol. You can’t force an overseas exchange to comply with your court order. Traditional enforcement mechanisms — freeze orders, asset seizures, transaction blocks — all assumed you controlled the payment rails. What happens when you don’t?

Taxation breaks. Income tax, VAT, capital gains tax — all designed for visible economic activity flowing through institutions you can monitor. If someone gets paid in crypto, spends it in crypto, and never converts to pounds or euros, how do you tax it? The entire tax system assumes you can see income and transactions. What if you can’t?

Monetary policy breaks. If people start using stablecoins or cryptocurrency instead of pounds, the Bank of England can’t control the money supply. Interest rate policy doesn’t work if people aren’t borrowing in your currency. Quantitative easing is meaningless if your currency isn’t the one people actually use. Central banks have tools that only work if people use the currency they control.

Brand becomes irrelevant. This might be the most disorienting part. For centuries, currency brands mattered. The pound was British identity. The dollar was American power. Exchange rates were national scoreboards. But if currency becomes invisible infrastructure — if people just tap their phones and value moves without them knowing or caring what’s underneath — does the brand matter anymore?

Do people develop loyalty to infrastructure? Do they care about the protocols running behind their apps? Or do they just care that it works?

THE 197 QUESTION

There are approximately 197 official currencies in the world today. Every country thought they needed their own to maintain sovereignty.

That’s 197 brands. 197 walled gardens. 197 separate control systems.

But here’s what’s worth asking: did those 197 currencies add value to citizens? Or were they primarily control points for governments?

The official story is that every country needs its own currency for monetary policy tailored to its economy, for stability and trust, for protection from external shocks, for national economic independence.

But look at what actually happens with most of those currencies. High inflation because small economies can’t maintain stability like major currencies. Exchange rate volatility that punishes citizens. No international acceptance — try spending most of these currencies abroad. Capital flight — wealthy citizens keep money in dollars or euros anyway.

For most people in most countries, their national currency doesn’t add value. It adds friction. They’d probably prefer to use dollars or euros or something else stable and widely accepted.

But they can’t easily opt out. That’s not choice — that’s captivity.

Now imagine a digital world where opting out is trivial. Where using a different currency is as easy as choosing a different app. Where geography doesn’t force you into your government’s monetary system.

How many of those 197 currencies remain relevant?

Maybe the major reserve currencies survive — dollar, euro, yuan, yen, pound. Maybe five to ten total.

Maybe it’s even fewer. Maybe just two or three dominant stablecoins or protocols that work everywhere, accepted by everyone.

Or maybe people don’t even think in currencies anymore. They just see numbers on screens that go up and down, with no idea what’s actually moving beneath.

The question isn’t just about how many currencies survive. It’s about whether currency as a concept — as something people relate to, identify with, make choices about — matters anymore at all.

WHICH BRANDS WIN? (AND WHY THAT TERRIFIES SOME GOVERNMENTS)

If currency becomes invisible infrastructure, which brands do people actually see and trust?

Is it Circle and USDC? A US company issuing dollar-backed stablecoins. Tether? Questionable reserves but massive adoption. Ethereum? A protocol with no country attached. Apple Pay? Google Pay? The interfaces people actually touch. Visa and Mastercard? Already global payment brands. Alipay? WeChat Pay? Chinese platforms with billions of users.

Do people care about “the pound” or “the euro”? Or do they care about whichever interface makes payments easy?

Here’s where geopolitics gets complicated.

It’s one thing for a government to lose control to a decentralised protocol. Uncomfortable, yes. But at least it’s neutral. Nobody controls it. It’s like losing to mathematics.

It’s something else entirely to lose control to another country’s systems.

Imagine you’re the French government. You discover that most French citizens are actually using USDC — a US-based, dollar-backed stablecoin — for daily transactions.

You’ve just lost monetary sovereignty to the United States — again, but worse this time. Given visibility of French transactions to an American company. Made French taxation dependent on US corporate cooperation. Handed control of your economy to American systems.

That’s not just losing sovereignty. That’s handing it to your geopolitical rival.

For most governments, that’s unacceptable.

Which is why Europe pushes regulations like MiCA so aggressively — can’t let US stablecoins dominate. Why China banned crypto but races to build digital yuan — can’t let anyone else control Chinese money flows. Why the UK wants a digital pound — can’t let the pound brand become irrelevant or, worse, controlled by American companies.

The sovereignty question becomes: would you rather lose control to decentralised protocols where nobody’s in charge? Or lose control to another nation’s brands and systems?

Most governments pick option three: try desperately to stay relevant with their own digital currency. Even if it’s a long shot. Because option two — ceding monetary control to another country — is politically impossible to accept.

HOW THEY’RE REACTING

Governments aren’t standing still. They’re trying different approaches, with varying degrees of desperation and sophistication.

Ban it. China’s approach. Outlaw cryptocurrency exchanges. Make it illegal to trade or use. Push everyone toward the official digital yuan. This works if you have authoritarian control and citizens who comply. But it’s hard to enforce completely. Activity goes underground. Innovation moves to other countries. And you can’t ban mathematics — code and protocols flow across borders regardless of what any single government wants.

Regulate it to death. Europe’s instinct. Create comprehensive frameworks like MiCA. Require KYC and AML for everything. Make compliance so onerous and expensive that crypto remains niche. The hope is to protect the euro and traditional banking by making alternatives too difficult to use. The risk is that innovation moves to more permissive jurisdictions, and Europeans miss out on whatever comes next.

Launch CBDCs. Create official digital currencies — digital pound, digital euro, digital dollar. Try to compete. Offer a government-backed alternative that’s better than private stablecoins. This assumes people will trust and prefer government digital money. But will they? If a government CBDC is slower, more expensive, more surveilled, or less convenient than alternatives, why would anyone use it? Governments have never had to compete for users before. They’re not good at it.

Accept and adapt. This is the hardest option psychologically. Admit you’re no longer the monopoly. Find new ways to tax and enforce that don’t depend on controlling the rails. Tax at different points — property, consumption, wealth. Develop new tools for enforcement that work in a world of partial visibility. Acknowledge that monetary sovereignty looks different now, and figure out what governance means when you can’t control the pipes.

None of these are easy. All of them require admitting that the game has fundamentally changed. That the assumptions underpinning government financial control for thousands of years are no longer valid.

That’s a hard thing for institutions to accept.

THE QUESTIONS WE SHOULD BE ASKING

So here we are.

Governments built entire systems — taxation, monetary policy, law enforcement, economic management — on the assumption that they controlled money within their borders. That assumption held for millennia because physics enforced it.

Now physics doesn’t enforce it anymore.

Can governments govern effectively without monetary control? Taxation, sanctions, monetary policy, financial crime enforcement — all depended on visibility and control over money flows. If they lose that, what’s left? What new tools do they need? Or do they need to rethink what governance means?

Should every country have its own currency? We have 197 of them. How many actually serve their citizens better than using a major currency would? Was currency diversity a feature of sovereignty, or just an artefact of geography that’s no longer necessary?

Which brands will people actually trust? Governments, private companies, protocols, or payment interfaces? When currency becomes invisible, where does trust attach? And does it matter?

Is losing control to decentralised systems better or worse than losing it to other countries’ systems? There’s a meaningful difference between losing sovereignty to mathematics and losing it to American or Chinese companies. Which is worse? Which is more dangerous?

What does sovereignty mean when borders don’t contain value? For a thousand years, sovereignty meant control over a territory. But digital value doesn’t respect territories. Does sovereignty need to be redefined? Can a government be sovereign if it doesn’t control its monetary system?

Can governments compete when they’ve never had to before? They’ve been monopolies forever. Now they have to win users. Offer better service. Be more convenient than private alternatives. Most government institutions aren’t built for competition. Can they learn? Should they?

We don’t have good answers to these questions yet. Neither do governments. Neither does anyone else.

But the questions are real, urgent, and unavoidable.

WHAT COMES NEXT

Lest we forget: what we have now isn’t even physical value anymore. It’s a promise. When we abandoned the gold standard, money became trust — a collective agreement that these numbers mean something.

We’re managing promises with systems designed for gold.

And now those promises might flow through channels governments don’t control. Trust might attach to protocols instead of nations. The container that held monetary sovereignty for thousands of years has cracks.

What happens when it breaks completely?

In Episode 1, we saw how payment systems are still designed for physical gold that left the vault decades ago.

In this episode, we’ve seen how sovereignty was built on territorial control that digital value doesn’t respect.

But there’s something even more fundamental that changes when money becomes pure information.

For thousands of years, money worked because it was scarce. You couldn’t copy gold. You couldn’t duplicate coins. Scarcity was built into the physics of physical objects.

Digital information isn’t scarce. It’s infinitely copyable.

So what happens to money — and everything money enables — when scarcity isn’t the constraint anymore?

That’s Episode 3.
