This guide covers the Nigerian naira series in the FXMacroData production catalogue. The NGN set is small and focused on the Central Bank of Nigeria: the Monetary Policy Rate, daily gross external reserves, the deposit rate and the central bank's balance sheet. The guide explains each series, when the CBN publishes it in Lagos time and UTC, and how traders following USD/NGN use the data.
Quick answer
What is covered
4 NGN series: the CBN Monetary Policy Rate (MPR), daily foreign reserves, the monthly deposit rate and monthly central bank assets.
Who publishes it
The Central Bank of Nigeria (CBN), for all four series.
Why it matters
Since the CBN began unifying its exchange-rate windows in 2023, the naira has been far more market-driven. The policy rate and the reserve buffer are the two official numbers that most directly shape USD/NGN.
Takeaway: For NGN, the reserves series is the most actionable: it is daily, it measures the CBN's capacity to supply dollars, and it often moves before the exchange rate does.
Who Publishes Nigerian Data
All four series come from the Central Bank of Nigeria (CBN). The CBN's Monetary Policy Committee (MPC) sets the Monetary Policy Rate, the anchor for naira interest rates, and publishes a communique at the end of each meeting. The CBN also publishes daily gross external reserves, monthly money and banking statistics (including average deposit rates) and its own balance sheet.
The policy backdrop matters for reading the data. In June 2023 the CBN began collapsing Nigeria's multiple official exchange-rate windows into a single market, and it has since moved towards a market-determined naira with an electronic FX matching system. That shift means the exchange rate now responds to interest rates, dollar liquidity and reserves much more directly than under the old managed regime, which in turn makes these four series more useful for USD/NGN analysis.
FXMacroData stores each value with the period it describes (date) and the moment it was published (announcement_datetime, Unix seconds), and serves it through the REST API, dashboards and MCP server. Releases are typically available within seconds of official publication (release speed).
NGN Indicators Covered
Policy rate
- CBN Monetary Policy Rate (MPR): the benchmark rate set by the MPC, recorded at every meeting including holds. Nigeria's policy rate is high by global standards because inflation has been high; the level of real rates (the MPR minus inflation) is central to whether foreign portfolio investors are willing to hold naira assets.
Reserves
- Foreign reserves: the CBN's gross external reserves in USD billions, published daily. Reserves fund the central bank's FX sales and signal its ability to smooth the naira. Rising reserves have tended to coincide with a steadier or stronger naira; sustained drawdowns have often preceded depreciation.
Money and credit
- Deposit rate: the monthly average rate banks pay on deposits. Comparing it with the MPR shows how much of the policy stance is passed through to savers, and it is the rate a local investor compares with holding dollars.
- Central bank assets: the CBN's total assets in NGN millions, monthly. The balance sheet reflects the central bank's lending to government and banks and its FX operations. This series is published with a long lag, so it is a structural rather than a trading indicator.
The NGN catalogue does not currently include CPI, GDP or trade data. For inflation context, the National Bureau of Statistics publishes the monthly CPI, and the CBN's MPC communique summarises it at each meeting.
NGN Release Timing
Nigeria uses West Africa Time (Africa/Lagos, UTC+1) all year, with no daylight saving.
| Release | Publisher | Frequency | Local time (Africa/Lagos) | UTC |
|---|---|---|---|---|
| MPC decision (communique) | CBN | About 6 meetings a year | Afternoon, after the meeting ends (around 14:00) | Around 13:00 |
| Gross external reserves | CBN | Daily (business days) | Around 17:00 | Around 16:00 |
| Deposit rate | CBN | Monthly | Early in the following month | Varies |
| Central bank assets | CBN | Monthly, published with a lag of several months | Varies | Varies |
The MPC communique is read out at a press briefing when the two-day meeting ends, so there is no fixed minute; FXMacroData's announcement_datetime records when the decision was actually published. Upcoming meeting dates are on the release calendar.
Worked Example: The September 2026 MPC Decision
At its September 2026 meeting the CBN's Monetary Policy Committee cut the MPR by 350 basis points, from 26.5 per cent to 23.0 per cent. The request:
curl -H "X-API-Key: YOUR_API_KEY" "https://api.fxmacrodata.com/v1/announcements/ngn/policy_rate?start_date=2026-09-01"The latest row returned (abridged to the fields used here):

"announcement_datetime_local": "2026-09-22T14:00:00+01:00"
}
]
}The epoch 1790082000 is 13:00 UTC on 22 September 2026, which is 14:00 local time (Africa/Lagos) on 22 September 2026.
The series puts that move in context. The MPR stood at 27.0 per cent in November 2025, was trimmed to 26.5 per cent in February 2026, and was then held in May and July before the September cut. A 350 basis-point move is large for any central bank, which is exactly the kind of event where knowing the publication minute matters for measuring the naira's response.
The reserves series adds the other half of the picture. Gross external reserves were USD 54.93 billion on 30 September 2026, up slightly from USD 54.88 billion on 25 September, so the cut came with a stable reserve buffer rather than a drawdown. Request the reserves series by replacing policy_rate with foreign_reserves in the URL above.
The deposit-rate series shows how little of the policy rate reaches savers. The average deposit rate was 12.69 per cent in August 2026, against an MPR of 26.5 per cent at the time, a gap of more than 13 percentage points. Deposit rates had moved between 10.4 and 11.6 per cent in late 2025 and early 2026 to the 12.3 to 12.7 per cent range from April onwards. Whether that range holds after a 350 basis-point policy cut is one of the clearest pass-through tests the catalogue offers, and it will show up in the next monthly deposit-rate rows.
How Traders Use NGN Data
- Real rates and portfolio flows. Foreign investors in Nigerian treasury bills and open market operation bills compare the MPR and deposit rates with inflation and with expected naira depreciation. A large cut lowers that carry, which can reduce portfolio inflows unless inflation is falling as fast.
- Reserves as the early-warning signal. Because reserves are published daily, a trend in the series can show tightening or easing dollar liquidity before it appears in the exchange rate.
- Oil and reserves. Crude oil is Nigeria's main source of export earnings and of the dollars that build reserves. Traders often read the reserves series alongside oil prices and production news.
- Policy-rate pass-through. The gap between the MPR and the deposit rate shows how much of a policy change reaches the real economy, and whether holding naira deposits competes with holding dollars.
- Balance-sheet context. Central bank assets help explain longer-run naira pressure, for example when central bank financing of government expands the money supply.
