6M Fundamental Drivers: A Conditional Evidence Ledger
Consider a week in which Mexican inflation is firm, U.S. growth surprises higher, Banxico sounds cautious, trade-policy uncertainty rises, and global equities rally. Counting “peso-positive” and “peso-negative” headlines cannot resolve that mix. A defensible 6M view starts from a dated prior, ranks evidence by transmission channel, and keeps competing branches alive until observable markets confirm or reject them.

What this page owns
The Broad Map Integrates Specialist Channels; It Does Not Replace Them
This is the canonical 6M driver map. It defines the shared evidence families and the weekly integration process. The carry, Banxico, trade/remittance, and U.S.-dollar pages own depth on their named mechanisms. Contract specifications and empirical claims live elsewhere.
A valid output
A falsifiable evidence branch
Example form: “If Mexican policy-sensitive yields rise relative to comparable U.S. yields, the move is not a credit-stress signal, and quote-correct 6M confirms in executable conditions, evidence favors the stronger-MXN branch.” This is an inference, not an official conclusion.
An invalid output
A deterministic driver slogan
“Higher Mexican inflation makes 6M rise” omits the prior, Banxico's likely response, the U.S. side, real-return implications, risk premium, and what price already reflected.
Established fact: CME lists 6M in U.S. dollars per Mexican peso. Higher 6M means stronger MXN against USD; the familiar USD/MXN spot quote is reciprocal. A dated future can differ from spot because of basis and contract lifecycle. Verify mechanics in the 6M contract guide.
Freeze what was knowable
Start With a Prior, Not With the Latest Headline
A prior is the timestamped state of official data, market expectations, known events, and uncertainty before new evidence arrives. It need not predict direction. Its purpose is to prevent hindsight from changing what counted as a surprise.
The pre-week evidence packet
Record the active dated contract and roll condition; the most recent Banxico and FOMC packages; chosen Mexican and U.S. policy-sensitive rates; latest official inflation, activity, labor, trade, fiscal, and balance-of-payments vintages; known release times; broad-dollar and risk observations; and market-quality constraints. Preserve links and retrieval times.

| Label | Meaning | Example form |
|---|---|---|
| Established fact | Official release, policy text, verified contract term, or timestamped observation | “INEGI published the release at the recorded time and later marked the vintage preliminary.” |
| Mechanism | A plausible causal path, stated conditionally | “A relative Mexican rate repricing may increase demand for MXN exposure, all else equal.” |
| Hypothesis | A predeclared, testable claim for this episode | “The relative-rate channel should dominate over the next declared window.” |
| Inference | The analyst's interpretation of combined evidence | “The evidence currently favors, but does not prove, the stronger-MXN branch.” |
| Possible application | A decision rule with execution and risk gates | “Consider only if price confirms and the market-quality gate passes.” |
Seven evidence families
Map Each Driver to the Variable It Can Actually Change
These families are containers, not independent votes. One release can affect policy expectations, growth, and risk premium simultaneously. Record the primary transmission path and cross-reference secondary paths instead of counting the release several times.
| Driver family | Primary official evidence | First question | Common failure |
|---|---|---|---|
| Banxico–Fed expectations | Banxico statement/minutes/reports; FOMC statement/minutes/projections; matched rate observations | Which expected path changed more, at what horizon, and why? | Comparing two current target rates as if they were an investable forward return |
| Inflation | INEGI INPC and components; Banxico forecasts and risk balance; U.S. BLS/BEA releases | Did the persistence or policy outlook change relative to prior? | Calling every upside surprise peso-positive without checking real rates or risk premium |
| Growth and labor | INEGI GDP/activity/labor releases; U.S. BEA/BLS/Census evidence | Did relative demand, slack, or policy expectations change? | Mixing monthly, quarterly, nominal, real, preliminary, and revised series |
| Trade and external flows | INEGI merchandise trade; Banxico balance of payments/remittances; U.S. Census trade | Did conversion demand, external income, imports, or hedging behavior plausibly change? | Turning an annual flow total into a same-day futures signal |
| Fiscal and political risk | SHCP finance/debt reports, legislation, official budget documents, election and regulatory records | Did expected financing needs, credibility, growth, or risk premium change? | Using commentary or ratings headlines instead of the underlying official document |
| Global dollar and risk | Federal Reserve H.10 dollar indexes and bilateral rates; declared volatility, credit, equity, and commodity observations | Is 6M responding to a common-dollar/global shock or a Mexico-specific shock? | Treating a dollar basket containing MXN as independent proof about MXN |
| Positioning and liquidity | CFTC delayed positioning; exchange/broker market observations; dated futures volume and spread data | Could crowding, roll, or poor depth amplify or distort the macro response? | Calling delayed regulatory categories live order flow |
Source boundary: Banco de México identifies low and stable inflation as its main objective, while the Federal Reserve describes its congressionally assigned U.S. monetary-policy goals. Those mandates are established facts. How markets map a particular release into relative rates and 6M is a conditional mechanism.
Weight by information, not drama
Rank New Evidence Through Four Filters
A release's market importance is not its headline size. The same numerical surprise can matter differently when it changes the expected policy path, confirms a persistent trend, arrives in a crowded market, or conflicts with the other side of the currency pair.
Surprise
Compare the outcome, revisions, and relevant components with the frozen expectation—not with a forecast remembered after release.
Persistence
Ask whether the information changes the path or is likely to be transitory, noisy, seasonal, or revised.
Relative repricing
Observe Mexico and U.S. instruments at comparable horizons and timestamps. A larger U.S. change can reverse the Mexico-only inference.
Independent confirmation
Require quote-correct 6M, spot, broader FX, and market-quality evidence that does not merely restate the same input.
New official evidence changes a previously priced path, survives revisions/components, reprices the relative curve, and receives independent currency confirmation.
The release changes one channel but competes with another material force, or confirmation is partial.
The headline is close to prior, offset internally, stale, or already reflected in market pricing.
The source, timestamp, unit, revision status, quote direction, or contract mapping cannot be verified.
Competing causal stories
Write the Base, Opposing, and Stand-Aside Branches Before Confirmation
The purpose of branches is not to cover every possible outcome after the fact. Each branch must name its expected channel, observable confirmation, and failure condition before price resolves.
| Branch | Evidence configuration | 6M hypothesis | What rejects it |
|---|---|---|---|
| Stronger-MXN branch | Mexican policy/growth evidence improves relative to the U.S.; risk premium does not deteriorate; external evidence is neutral or supportive | 6M may rise if the relative-rate and currency complex confirm | U.S. repricing dominates, broad-dollar stress rises, or 6M fails the declared level |
| Weaker-MXN branch | Mexican expected returns or growth weaken relative to the U.S., or fiscal/trade/global-risk evidence raises the required premium | 6M may fall if cross-market evidence and executable price action confirm | Mexico–U.S. spread recovers, risk stress fades, or the breakdown fails |
| Offset branch | Policy support and risk deterioration, or trade weakness and broad-dollar weakness, point in opposite directions | Direction and timing remain indeterminate | A predeclared channel gains independent confirmation while rivals weaken |
| Stand aside | Conflicting releases, data-quality failure, roll distortion, event overlap, or unacceptable market quality | No trade conclusion | Only a fresh, verifiable evidence set can reopen the decision |
Application boundary: even a confirmed macro branch is not an order. Contract month, spread, depth, slippage, invalidation distance, gap risk, position size, and maximum loss belong in the integrated 6M trading plan.
Three clocks
Separate Event Reaction, Follow-Through, and Macro Validation
Different horizons answer different questions. Collapsing them creates false confidence: a first-minute move can reverse, while a monthly macro thesis can be too slow to justify an intraday order.
Event clock
Minutes to session close
Did policy-sensitive rates and quote-correct FX move consistently with the declared surprise? Were spreads and depth usable? This tests the immediate interpretation, not long-run causality.
Follow-through clock
Next sessions
Did the relative-rate change persist, did 6M hold the confirmation area, and did rival explanations weaken? A reversal can invalidate the event branch.
Macro-validation clock
Over later releases, ask whether official revisions and new data confirm the hypothesized policy, growth, trade, or risk-premium path. Preserve the real-time record separately from the revised-history record. A later data revision may improve the economic history without changing what was tradable at the original cutoff.

Maintain One Driver Ledger, Then Route Depth to the Specialist Pages
Complete one row per material update. If a row cannot identify the source, prior, channel, rival, confirmation, and failure condition, it is not ready to influence the decision.
| Ledger field | Required entry | Audit question |
|---|---|---|
| Cutoff | Date, time, timezone, contract, roll state, data vintage | Could later information have leaked in? |
| Established fact | Descriptive primary-source link and exact released content | Is this fact, or my paraphrased inference? |
| Prior and surprise | Expectation source, range, revisions, components | Was the prior frozen before release? |
| Primary mechanism | Policy, growth, trade, fiscal/risk, dollar, or positioning channel | Did I count the same release more than once? |
| Relative evidence | Matched Mexico and U.S. observations at declared horizons | Did the second currency change the conclusion? |
| Rival explanation | Strongest competing causal story | What observation would favor it instead? |
| Confirmation | Independent rate, FX, and market-quality conditions | Are any signals circular? |
| Invalidation | Observable thesis and execution failure conditions | Would I accept “unclear” when they occur? |
| Review | Outcome by clock, process error, revised data kept separately | Am I grading reasoning rather than P&L alone? |
Research status: this page provides an evidence architecture and decision workflow. It assigns no empirical weights, reports no driver ranking, and claims no forecasting or trading performance. Those claims require a point-in-time dataset, synchronized observations, declared transformations, costs, and untouched validation periods.
