Market context

The Bank of Korea's monetary policy committee will convene on 28 May 2026 to decide whether to adjust its base rate. This market resolves YES if the committee changes the rate at that meeting, and NO if it holds steady. The current 0% implied probability on Polymarket's order book reflects strong conviction among traders that no rate change will occur, though this assessment rests on limited forward guidance and economic conditions that remain subject to revision.

South Korea's central bank has historically maintained measured adjustment cycles, with rate decisions typically clustered around broader economic inflection points rather than dispersed across consecutive meetings. The BOK held rates steady through much of 2024 and early 2025 amid mixed inflation signals and subdued growth, establishing a pattern of patience between moves. When changes do occur, they tend to follow explicit forward signalling or material shifts in inflation or employment data, neither of which has emerged prominently in recent communications regarding the May meeting.

Traders monitoring this decision should track BOK communications in April and early May, particularly any revision to growth or inflation forecasts in official statements. Recent won weakness and export performance data will inform expectations, as will movements in global interest rates—particularly Federal Reserve signals, which historically constrain BOK flexibility. The settlement window closes at the conclusion of the May 28 meeting, leaving minimal time for post-announcement repricing.

How active is this market?

$85K in lifetime turnover and $33K of resting liquidity puts this market in the above the median by volume for economic policy contracts on PolyGram. Order-book depth is strong — order books support five-figure trades with single-cent slippage.

Last 24 hours alone saw $3K in turnover, consistent with the market's lifetime daily-average pace.

The market has been open for 2 months — the price has had time to stabilise as new information arrived.

Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.

Key terms

YES / NO share: A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
CLOB: Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
Liquidity: USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
UMA optimistic oracle: The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
Slippage: The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
Conditional token: ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.

Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
