Resolution criteria on PolyGram: This market will resolve according to the change in basis points in the target for the overnight interbank interest rate resulting from the August 2026 meeting of the Bank of Mexico, relative to the level it was prior to this meeting. The resolution source will be official information from the Bank of Mexico, including the statement or release from its August 2026 meeting, scheduled for August 6, 2026, as listed on the official Bank of Mexico calendar (https://www.banxico.org.mx/viewers2/JSP/calendarioDifusion_es.jsp). This market may resolve as soon as the statement or release of the Bank of Mexico resulting from its August 2026 meeting with relevant data is issued.

The Bank of Mexico's monetary policy committee will convene on 6 August 2026 to decide whether to adjust the overnight interbank interest rate target. The market currently prices a 38% probability of a rate change, reflecting uncertainty about whether Banxico will hold steady or move in either direction. The settlement hinges on the official announcement from that meeting, with any basis point shift—whether an increase or decrease—resolving the market as YES.
Banxico's recent decisions provide context for interpreting current odds. Between 2022 and 2023, the central bank executed an aggressive tightening cycle, raising rates from near-zero to over 10% in response to inflation pressures. By mid-2024, the committee had begun a gradual easing cycle as inflation moderated towards its 3% target. The 38% probability suggests traders anticipate roughly a two-in-five chance of movement in August 2026, consistent with a central bank in a measured adjustment phase rather than one signalling imminent or dramatic shifts.
Traders should monitor inflation data releases in the months preceding the August meeting, particularly the National Institute of Statistics and Geography's consumer price reports, which directly influence Banxico's forward guidance. Currency movements and US Federal Reserve signals also matter substantially, given the peso's sensitivity to interest rate differentials and capital flows. The committee's previous statements and any interim communications will telegraph its stance. Polymarket's order book will tighten as the meeting approaches and fresh economic data arrives, with the current 38% reflecting the dispersed expectations of active traders today.
