Rubber Monthly Price Assessment – July 2026

1. Data Collection – How the Prices Are Sourced

Our approach adheres to a “multi-source triangulation” philosophy. Prices are collected through a combination of primary, secondary, and regulatory / institutional channels to ensure comprehensive coverage and authenticity.

a. Primary Market Inputs

• Direct submissions from market participants, distributors, or partner organizations where available.
• Periodic structured inputs received from local industry stakeholders, including survey-based price declarations or partner-verified updates.
• Internal client or proprietary systems that track transactional price points or procurement records.

b. Public & Government Sources

• Ministries of Economy/Finance/Commerce in the US, India, Europe, Saudi Arabia, UAE, and other covered regions.
• Government statistical authorities (e.g., General Authority for Statistics, CAPMAS, Federal Competitiveness & Statistics Centre).
• Central banks and monetary authority bulletins.
• Customs datasets and price indices published in official monthly releases.

2. Data Cleaning – How the Prices Are Processed

After collection, raw data flows into the historical cleaning sphere, where a controlled series of automated quality steps transform source inputs into a model ready dataset.

a. Standardization & Structural Checks

• Dates are normalized to a monthly granularity.
• Country-specific price fields are benchmarked against expected ranges using historical patterns.

b. Outlier Detection & Smoothing

• Z-score thresholds and rolling window deviation rules identify anomalies.

c. Missing Data Management

• Gaps are filled using time-series appropriate techniques:
• Forward/backward fill for short gaps
• Trend-based interpolation for larger gaps
• Full exclusion from regression if deemed non-recoverable

d. Residual Diagnostics

• Within the historical sphere, formulas auto-compute:
• Fitted values based on the regression model
• Residuals highlighting deviation between actual and modeled values
• Errors to support accuracy metrics
• This creates a transparent lineage between raw data, cleansed data, and model inputs

3. Validation – How Prices Are Validated

Before any final price series is published or forecasted, the dataset undergoes multi-layer validation.

a. Source Verification

• Prices are compared against multiple independent sources.
• Discrepancies beyond tolerance thresholds initiate a source confidence review.
• Internal month-on-month and year-on-year movement rules highlight potential unusual market events.

b. Statistical Model Validation

• The model automates multiple tests to ensure forecasting credibility:
• Linear trend validation
• Slope and Intercept for each country are estimated.
• Trends are reviewed for stability, directionality, and economic plausibility.
• Seasonality calibration

c. Analyst Review & Sign-off

• A human-in-the-loop process ensures contextual and macroeconomic factors are considered. Final validation involves:
• Analyst comments
• Exception logging
• Approval by a senior reviewer

4. Forecasting – How Future Prices Are Derived

Once verified, the cleansed dataset is used to generate 6-month or extended forecasts through the adjustment of intercept, slope (time extension) and seasonal adjustments.

a. Baseline Trend Component (Intercept)

• Each country’s historical price series is modeled using a linear regression.
• The intercept represents the baseline price level at the start of the observed period.
• This provides the foundational anchor point from which future price projections extend.

b. Direction & Speed of Movement (Slope × Time Extension)

• The slope measures how prices have evolved over time, capturing whether the trend is upward, downward, or stable.
• During forecasting, the model extends this trend by calculating how far the forecast month is from the last historical observation (“time extension”).
• This ensures forecasts follow the empirically derived trajectory of each market.

c. Seasonal Adjustment Component

• Markets often exhibit predictable seasonal patterns such as cyclical fluctuations tied to consumption cycles, policy periods, or market operations.
• Seasonality is measured using monthly average residuals from the regression model. These adjustments are added to each forecasted month, ensuring that estimates reflect recurring, month-specific effects rather than purely linear trends.

5. Governance – Monthly Update Cycle

• Each month, analysts follow a structured update protocol. This creates a repeatable and transparent reporting cadence aligned with enterprise-level forecasting standards.
• Add new actuals to the model
• Let formulas auto-update
• Review metrics for accuracy
• Validate unusual market behaviors
• Publish updated forecasts to users / dashboards
