The question that decides whether this is worth anything
Every fiat currency began backed by something. Every one of them ended up issued at will. The dollar was gold-convertible until August 1971; sterling was too, until it wasn't. So a sovereign minting facility is only interesting if it answers one question: what stops the government over-issuing?
“A binding commitment not to” is precisely what every fiat currency already has, and it has never held. If MSaaS relies on the same thing, it is a rebrand.
The only answer worth building is the one this system already uses everywhere else: the ledger refuses. A PAM draw beyond accrued entitlement does not execute. An unbalanced posting does not execute. A fractional penny cannot be encoded at all. Issuance beyond verified backing is treated the same way — not flagged for review, not subject to ministerial override, not a policy that can be suspended in a crisis. It does not execute. Everything below is built on that.

Sovereign asset register
What this changes for a government
| Conventional fiat issuance | MSaaS issuance | |
|---|---|---|
| Limit on issuance | Self-imposed. Suspendable by the issuer at any time. | Capacity computed from verified assets. The ledger will not execute beyond it. |
| Who verifies backing | The issuer, if anyone. | Two independent valuations per asset class, bound to the record and re-verified on a set cycle. |
| Effect of over-issuing | Debasement. Diffuse, slow, and paid for by holders who did not consent. | The instruction is refused and the attempt is recorded permanently. |
| Visibility to holders | Money supply published after the fact, revised, and hard to interpret. | Backing ratio visible continuously. A holder can check it themselves. |
| Monetary sovereignty | Total. | Constrained by the state's own asset base — which is the point, and also the hardest thing to sell. |
Why a government would refuse this, and the honest answer
A finance ministry in a crisis wants exactly the flexibility this removes. Deficit spending, emergency stimulus, wartime finance and bank rescues all depend on issuing beyond current backing. A system that structurally forbids it is not a feature to them — it is a loss of the instrument they most rely on.
So the realistic adopter is not a large developed economy with a functioning bond market. It is a state whose currency already lacks credibility, where the ability to prove restraint is worth more than the ability to abandon it: a nation rebuilding after hyperinflation, a resource-rich state whose currency trades at a discount to its balance sheet, or a monetary union member wanting a hard parallel unit.
Pretending the constraint is universally attractive would waste the first meeting. The pitch is not “this is better for everyone”. It is “for a state that has lost monetary credibility, provable restraint is cheaper than earning trust back over a generation”.
What this page is, and isn't
What's real here
The arithmetic is real: advance rates are applied per asset class, capacity recomputes as you change the register, and the issuance request is genuinely refused when it exceeds capacity — the refusal is a real code path, not a message. Refusals are recorded as ledger entries alongside successful issuance, so an attempt to over-issue leaves a permanent trace. The advance rates reflect ordinary collateral practice: liquid, continuously priced assets carry high rates; contingent and illiquid ones carry low ones; forward tax receipts carry zero, because lending against future taxation is the fiat model rather than an alternative to it.
What this is not
A concept model. No government has engaged with Meridian, no sovereign issuance has been discussed with any state, and Meridian holds no authorisation of any kind. The hardest problems are not modelled: who is accepted as an independent valuer of a sovereign asset, what happens when assets are nationalised, depleted, disputed or seized, how a state's existing debt stock interacts with a new unit, and what enforcement exists if a government simply legislates around the constraint — a ledger can refuse an instruction, but it cannot refuse an act of parliament. Currency issuance is an attribute of sovereignty and no private infrastructure can constrain it without consent that a state may later withdraw.
