How this site works

Data-led analysis of India's trade, currency and industrial policy. Every article is built from primary official sources, and every figure links back to the release, table or filing it came from.

Sources. DGCI&S TradeStat (imports/exports, HSN-wise) · PIB (government press releases, January 2017 to today, refreshed daily) · RBI (circulars, balance of payments) · MoSPI (CPI/WPI, IIP) · PARIVESH (environmental clearances) · CCIL (bond yields) · BIS (policy rates) · SEBI, NSE/BSE and SEC filings for company data.

Interpretation. Figures carry their vintage and retrieval date; estimates and press-reported numbers are labelled as such; where sources disagree, both are shown. Corrections are made visibly, never silently. Articles are written with AI assistance from the cited sources — AI-generated text can misstate figures even when working from real material, so verify any number that matters to a decision against the linked primary source.
