Three ways teams use the index
1. Treasury: price payouts against the street, not the official window
A treasury that pays out in local currency compares the official rate with the rate the market actually clears at. The parallel-market premium today:
| Currency | Official | Street index | Premium |
|---|---|---|---|
| INR | 95,22 | 97,02 | +1.9 % |
| KZT | 455,6 | 454,6 | -0.2 % |
| TRY | 49,84 | 51,30 | +2.9 % |
One API call per currency per day (/v1/rates/latest) feeds the pricing sheet; the official-vs-street product adds the official rate and the premium in the same row.
2. Remittance: the hour matters
On 2026-10-28 the hourly index of AZN moved between 1,7485 and 1,7497 over 20 hours with an index value (whole-day average 1,7490). A remittance desk that quotes customers during the day prices against the hour, not against yesterday's close.
/v1/rates/{cur}/hourly (Pro) returns the hours and the daily summary.
3. Research: where the street moved most
