What it means
The same cryptocurrency can trade on multiple exchanges with separate order books, and buyers and sellers in one market do not always have immediate access to another. When local demand and trading constraints differ, prices can diverge despite the asset being nominally the same.
Comparisons require currency conversion and synchronised observations, because both cryptocurrency prices and exchange rates can change rapidly. A premium is positive when the Korean price is higher after conversion, while a lower price produces a discount under the same signed comparison.
The gap need not appear on every exchange simultaneously. A simple price gap is different from a completed arbitrage transaction.
To capture it, a trader would need access to the relevant markets and a workable path for funds or cryptocurrency transfers, and execution, settlement, funding, and applicable restrictions can prevent the apparent opportunity from becoming a realised profit. The published 2024 study in Economic Modelling examines nonlinear dynamics and market frictions, finding different behaviour at different premium sizes within its analysis rather than treating every small discrepancy as an instantly exploitable trade.
Its statistical results describe the studied data and model, not a guaranteed current equilibrium. Market segmentation is part of the explanation, because if participants cannot readily move funds across markets, competition may not immediately eliminate a price gap.
Local demand can also differ, and trading fees or transfer delays can make a small premium uneconomic to pursue. Legal and account-access conditions need separate checking, since historical research discusses capital-flow restrictions and difficulties accessing Korean trading arrangements but should not be used as a current legal checklist.
A price chart does not prove that a specific person can open an account, transfer funds, or make the proposed trade lawfully. Data quality matters too, because quotes can be stale or shallow, and bid-ask spreads, order-book depth, and transfer costs can make a practical comparison differ from two headline prices taken from a website.
For non-finance managers, distinguish an observation about market pricing from a claim about easy money. Ask which exchanges, timestamps, currency rates, and costs support the calculation, and do not let a familiar name substitute for checking the feasibility and risk of any proposed action.
In practice
Real-world examples.
Example
A fictional analyst converts a Korean bitcoin quote into dollars and compares it with a simultaneous foreign quote. She reports the percentage difference with its timestamp instead of calling the number a permanent characteristic of bitcoin.
Example
A trader sees a positive price gap but cannot execute both sides immediately. His review includes the possibility that the spread changes during transfers, so the proposal is described as exposed to execution and market risk.
Example
A manager receives a presentation claiming a small premium guarantees profit. The team checks bid and ask prices for the intended quantity and finds that estimated costs exceed the apparent gross spread.
Formula
Calculation
Premium percentage = (converted Korean price / foreign price - 1) x 100. Use consistent units, timestamps, and exchange-rate conventions.
Assume fictional Korean price KRW70,000,000, exchange rate KRW1,400 per dollar, and foreign price $48,000. The converted price is $50,000 and the premium is ($50,000 / $48,000 - 1) x 100 = approximately 4.17%.
The $2,000 gross difference becomes $500 after $1,500 assumed costs, before other risks. These invented quotations are not current prices.Case study
Seen in the real world.
In this fictional case, Cedar Treasury reviews a proposed cryptocurrency transaction advertised as exploiting the kimchi premium. The pitch uses two screenshots taken at different times and does not specify a currency conversion rate. An analyst rebuilds the comparison with common units and synchronised observations. The team separates the spread from costs, timing, access, and legal requirements.
It does not assume that a historical study authorises the proposed route. The manager rejects the claim of guaranteed profit and keeps the calculation as a market observation rather than an approved transaction. The case shows why accurate measurement and executable trading are different questions, even when both involve the same price gap.
Watch out
Common mistakes.
- Comparing won and dollar quotations without currency conversion or matching timestamps.
- Treating a displayed premium as net profit without checking access, fees, liquidity, and transfer risk.
- Presenting a historical research finding as a fixed current premium or as permission for a specific transaction.
Questions
People also ask.
Is the kimchi premium a fee charged by exchanges?
No. It describes a relative market price difference. Trading fees are separate costs that can affect whether an apparent opportunity is worthwhile.
Does the premium always stay positive?
No. The price difference changes with market conditions and the chosen comparison. A negative signed result indicates a discount rather than a positive premium.
Does an observed gap prove arbitrage is possible?
No. A trader still needs lawful market access, workable funding and settlement, sufficient liquidity, and an assessment of costs and execution risk.
