Central banks post new exchange rates as Nigeria's street premium persists

Russia's and Saudi Arabia's daily rate prints anchor Friday's conversions

2026, listing official ruble values for selected foreign currencies without assuming any obligation. 355430. Together these two official prints give importers, payroll teams and travel-money desks a clean reference for the figures that entered their ledgers on Friday, and any spreadsheet that pulls a rate by hand should overwrite the cell with the day's official number before month-end.

Where a workbook needs a number extracted from a pasted rate-sheet, an Extract Numbers from Text utility keeps the typed figures out of formula errors.

Nigeria's official and street rates diverge by 11 September 2026

44 on 11 September 2026, while a separate street rate — set by different buyers and sellers for different transactions — continued to trade at a premium. The point of the spread matters for practitioners: a remittance sender, a small importer paying in dollars, or a naira-denominated freelancer billing a foreign client all face two published prices for the same currency on the same day. Anyone reconciling expenses should record both the official and street values on the same line, then book the realised naira at the rate actually paid, so the audit trail matches the cash that moved.

The wider lesson is that an official figure and a parallel-market figure are not interchangeable inputs in a calculator.

What the prints mean for Friday's cross-border calculations

Three different central banks or aggregators produced figures in the same news cycle, which lets a practitioner cross-check a rate rather than rely on a single feed. Russia and Saudi Arabia published identical-rate values on 12 September 2026, while Nigeria's 11 September 2026 official close sits a day earlier and is paired with an unofficial street quote. Anyone building a daily FX table should anchor the headline row to the central-bank print of the trade date, then add a footnote row for any market where a parallel rate materially differs.

A simple Social Security COLA Calculator is a reminder that the same discipline — single authoritative input, dated cell, source noted — applies to any number that drives a payment.

Practitioner follow-up: dates, sources and what to verify next

Before signing off on the week's FX work, three checks pay off. First, freeze the rate cell with the date the central bank printed it, not the date the file was saved. Second, where a jurisdiction has both an official and a parallel rate — as in Nigeria — record both on the same row so the realised cash reconciles to the rate actually paid. Third, revisit the page the next morning and overwrite the cell with the new official print. None of the items in this cycle name a pending release, so a reader who wants forward-looking context should watch the same central-bank feeds for the next daily table.
