Official vs Street: the parallel-market premium

How far the street (P2P USDT) rate is from the official central-bank rate, per currency and day: the premium people actually pay for dollars, with 7-day average and 30-day maximum.

Remittance companies and payout providers pricing local currency, OTC desks, treasury teams comparing their own rate with the market, funds and analysts tracking convertibility stress.

المصادر والتراخيص

المنهجية

Official vs Street

  • official — the central bank's official USD rate for the day, fiat per 1 USD, from a class-B source (open licence with attribution). Central banks publish on business days; a rate stays in force until the next publication, so for weekends and holidays the last published rate is carried forward for at most 4 days (official_day shows the publication day). Days without an official rate within 4 days have no row.
  • street_mid — the EMpulse Street FX Index mid for the same UTC day (see the index methodology); days with flag = outlier or without a valid mid are skipped.
  • premium_pct = (street_mid / official − 1) × 100. Positive: the street pays more fiat per dollar than the official rate implies. USDT is treated as 1 USD; the stablecoin's own small deviations from the dollar are part of the measured premium.
  • premium_7d_avg — arithmetic mean of premium_pct over the last 7 calendar days including the day; premium_30d_max — the maximum over the last 30 calendar days. Both use the days that have a row.
  • Sources per currency: UAH — National Bank of Ukraine (open data, CC-like terms, attribution); KZT — National Bank of Kazakhstan (data licence, attribution); INR, TRY — ECB euro reference rates crossed through USD/EUR of the same day (ECB copyright policy: reproduction with attribution). A currency appears only when its official source has passed the licence check (class A–D); class-E sources are never used.
  • Revisions: the street side is recalculated with every data load (see the index methodology); official rates are re-pulled for the last 7 days on every load.
