Why
The observation that opens the post is the good one: a very large won market was built without any won in it. An NDF settles the difference between an agreed rate and the fixing rate, in dollars, and delivers nothing. It exists because a foreign investor needs won exposure and cannot freely obtain or hold won, so the market synthesised the exposure and skipped the currency. That is not an exotic derivative story, it is a workaround with a price tag attached.
Which means the headline number is not what it looks like, and this catalogue has already made the identical move on a different Korean figure. korea-spot-share-is-an-artifact argues that a thirty percent share of global crypto spot is a restriction rather than a market size — the share is high because the alternatives were closed. The won NDF market is the same shape: its daily volume is a measure of non-deliverability, not of appetite for won. The practical consequence is the part that gets skipped. If deliverability arrives, that volume does not migrate wholesale to a new venue; a portion of it stops existing, because it was the cost of synthesising something that can now be held directly. Anyone forecasting how much NDF flow moves on-chain is answering a question with a hidden third option.
The post's own strongest line is the one to build the card on, though: making a currency usable and deciding who makes its market are different problems. Deliverability is a property of the instrument. Price discovery, liquidity and collateral are properties of a venue, and venues are chosen by whoever gets there first with depth. A won stablecoin that is issued domestically but traded mainly abroad, with USDC-KRW liquidity supplied by global market makers, would internationalise the won and simultaneously locate the price of the digital won offshore. Those two outcomes sound like one outcome and are not.
The reference case is the eurodollar, and the post does not name it. Dollar deposits outside the United States grew into a funding market that the US neither built nor controlled, and the lesson is not that it was bad — it is that it was never recovered. Once an offshore market for a currency exists at scale, the issuing jurisdiction does not relocate it; it builds facilities to reach it, which is what central bank swap lines are. So the honest framing for a won stablecoin is not whether an offshore digital won market will form but whether the domestic system will be a participant in it or a counterparty to it, and that is decided by who supplies liquidity and who holds the collateral, not by where the issuer is licensed.
Of the three demands the post separates, collateral is the one that decides the outcome, and it is the one least discussed. Hedging and leverage stay in derivatives because that is what derivatives are for. Procurement and settlement follow whichever rail is cheapest and will happily be onshore. But whoever holds the collateral makes the funding market, and a currency's offshore price is set in its funding market rather than in its spot market — the repo rate is where the marginal holder is priced. A won stablecoin used as collateral on foreign venues creates a won funding market outside Korean supervision, and that is the mechanism by which the third demand quietly outranks the other two. what-needs-a-stablecoin asks which transactions genuinely require one; this card asks the adjacent question the same way — not what the token can do, but which market it brings into existence.
How it works
Why a large won market has no won in it
| What it settles | What it delivers | Why it exists | |
|---|---|---|---|
| Deliverable forward | The rate | The currency | Normal market for a convertible currency |
| NDF | The difference, in dollars | Nothing | The currency cannot be freely obtained or held offshore |
So the volume is a price paid for a workaround. Read as demand it overstates; read as a measure of the restriction it is exactly right — the same reading korea-spot-share-is-an-artifact applies to Korea's spot share.
The forecast people make, and the option they leave out
| Where NDF flow goes if the won becomes deliverable | Usually considered? |
|---|---|
| Stays in NDF | Yes |
| Moves on-chain | Yes — this is the whole discussion |
| Stops existing | Rarely — it was the cost of synthesising a thing now directly available |
Any projection of "how much NDF migrates" that omits the third row is measuring against the wrong denominator.
The three offshore demands, and which one decides the outcome
| Demand | Where it goes | Why it matters |
|---|---|---|
| Hedging and leverage | Stays in derivatives | Derivatives exist for this; nothing changes |
| Procurement and settlement | Spot, wherever it is cheapest | Follows the rail; can be onshore |
| Liquidity and collateral | On-chain, wherever the depth is | Whoever holds the collateral makes the funding market, and a currency's offshore price is set in its funding market |
The third row is the one to watch, and it is the least discussed of the three.
The eurodollar precedent, stated as a rule
Dollar deposits outside the US became a funding market the US did not build and could not relocate. The response was not repatriation, it was swap lines — facilities to reach a market that had settled elsewhere. The rule that generalises: an offshore market for a currency is not recovered, it is reached. Which turns the policy question from will this happen into participant or counterparty.
The measurement, defined before there is anything to measure
Price discovery is which series moves first. Sample three at a common frequency — onshore spot, the NDF fixing, and the on-chain KRW-stablecoin rate on the deepest venue — and compute rolling lead-lag correlation. The leader is where the price is made. Defining it now matters more than running it now, because the interesting result is the change over time and that series cannot be reconstructed later. Same discipline as the observation window in monad-last-general-purpose-l1: a baseline nobody recorded cannot be recovered afterwards.
Where it lands in Jayverse
- Bridge/Token: log who holds locked collateral on each side. The lock-and-mint bridge between Anvil and Sepolia should record whether JYVE collateral sits on the source or destination chain, since collateral location — not deliverability — is what decides where a token's price actually forms.
- DeFi: run the lead-lag test between Devnet and Sepolia rates. Sample the liquid-staking token's Devnet price and its Sepolia-forked reference at a common frequency and compute rolling correlation, before assuming Devnet's price mirrors Sepolia's rather than leading or lagging it.
- Verex: separate "restriction size" from "demand" in resolution design. For a market on an asset whose real venue is hard to reach, the resolution field should say which venue's price is used and whether volume there reflects genuine demand or a workaround around the restriction.
