What Is the Real Return on Naira Savings After Inflation?

Put plainly: between 2018 and 2026, the real return on a standard naira savings account was deeply negative in every single year. The Central Bank of Nigeria (CBN) held the minimum savings deposit rate at 30% of the Monetary Policy Rate (MPR) for most of this period. When the MPR stood at 13.75% in mid-2022, the mandated minimum savings rate was just 4.1%. By the time the CBN raised the MPR to 27.25% in February 2025, the minimum savings rate had climbed to around 8.2%. Yet annual headline inflation, as measured by the National Bureau of Statistics (NBS), averaged 33.95% in 2024. The arithmetic is brutal: a saver earning 8% on naira deposits while inflation runs at 34% loses roughly 26 percentage points of purchasing power in twelve months.

The NBS Consumer Price Index (CPI) report for June 2026 placed year-on-year headline inflation at 15.91%, a moderation from the 33.95% average of 2024 following the NBS rebasing exercise completed in January 2026. Even with the rebased figure, the gap between deposit rates and inflation remains wide. Commercial banks routinely offer 7%–12% on retail savings accounts, against a rebased CPI that economists at Nairametrics caution may still understate the felt cost of living in Lagos and Abuja.

To calculate real return, the formula is straightforward: real return equals the nominal deposit rate minus the inflation rate. On that measure, naira savings have delivered negative real returns for eight consecutive years running from 2018 through 2026. The cumulative purchasing power loss over that span is staggering. A saver who held ₦1,000,000 in a standard savings account in January 2018 would need roughly ₦10,800,000 today to possess equivalent purchasing power, using NBS CPI data as the deflator. Their account balance, compounded at an average nominal rate of 5% annually, would stand near ₦1,477,000. The shortfall exceeds ₦9,300,000.

How Do Dollar Savings Compare to Naira Savings in Nigeria Over Eight Years?

The dollar side of the comparison requires two separate calculations: the nominal return earned on a dollar-denominated deposit or instrument, and the exchange rate gain expressed in naira terms.

Starting with the exchange rate component: the official CBN window rate moved from approximately ₦306 per dollar in January 2018 to ₦1,580 per dollar by mid-June 2026, according to CBN published rates. That represents a depreciation of roughly 417% in the naira's value against the dollar over eight years. A saver who held $1,000 in January 2018, worth ₦306,000 at the then-official rate, would find that same $1,000 convertible to approximately ₦1,580,000 at the June 2026 rate. Before accounting for any interest earned on the dollar deposit, the exchange rate movement alone delivered a naira-equivalent return of around 416%.

Against US dollar inflation over the same period, measured by the US Bureau of Labour Statistics CPI, the purchasing power of $1,000 in 2018 dollars fell to approximately $860 in real 2026 terms, reflecting cumulative US inflation near 16% from 2018 through early 2026. For a Nigerian saver, however, the relevant benchmark is Nigerian purchasing power, not American. Measured in naira terms, the dollar savings position dramatically outpaced naira CPI erosion.

A naira saver lost more than 90% of real purchasing power between 2018 and 2026. A dollar saver, measured in naira, saw their position multiply more than fourfold before interest.

Adding nominal dollar interest compounds the advantage. Treasury bills in the United States yielded near-zero from 2018 through 2021, but climbed sharply from 2022 onward as the Federal Reserve tightened policy. By mid-2024, US 3-month T-bills yielded approximately 5.3%. A disciplined dollar saver rolling short-term US instruments from 2022 to 2026 accumulated meaningful nominal dollar returns on top of the exchange rate tailwind.

The Caveat: Access, Regulation and Real-World Friction

The comparison above is arithmetically clean but operationally complicated. Nigerian residents face CBN regulations governing foreign currency accounts and transfers. The CBN's 2015 guidelines on domiciliary accounts allow residents to open and operate foreign currency accounts at licensed Nigerian banks, funded through personal travel allowances, diaspora remittances and approved inflows. Interest rates on naira-denominated domiciliary balances are typically zero or near-zero, meaning the dollar return for most retail savers is purely the exchange rate movement plus whatever modest interest a foreign counterpart account might earn.

The NGX (Nigerian Exchange Group) equity market offers a third datapoint. The NGX All-Share Index closed 2018 at approximately 31,430 points and stood near 98,500 points in June 2026, a nominal gain of roughly 213% over the period. Against cumulative naira CPI inflation of well over 300% from 2018 to 2026 using pre-rebase NBS data, even the NGX All-Share's solid nominal performance delivered a mildly negative to flat real return for a buy-and-hold investor who entered in 2018 and exited in mid-2026, before dividends. Including dividend yields, which NGX-listed banks and consumer goods firms have historically distributed at 4%–9% annually, some equity portfolios edged into marginally positive real return territory.

Year-by-Year Real Return Snapshot (2018–2025)

| Year | NBS Headline Inflation | Avg CBN Savings Rate (Est.) | Real Return (Naira) | USD/NGN Year-End (Approx.) | |------|------------------------|----------------------------|---------------------|---------------------------| | 2018 | 11.44% | 3.75% | -7.69% | ₦307 | | 2019 | 11.98% | 3.75% | -8.23% | ₦307 | | 2020 | 15.75% | 3.75% | -12.00% | ₦394 | | 2021 | 15.63% | 4.13% | -11.50% | ₦415 | | 2022 | 21.34% | 4.13% | -17.21% | ₦448 | | 2023 | 28.92% | 6.48% | -22.44% | ₦907 | | 2024 | 33.95% | 8.18% | -25.77% | ₦1,535 | | 2025 | 26.50%* | 8.18% | -18.32%* | ₦1,560* |

The table confirms what lived experience in Lagos, Kano and Port Harcourt already tells most Nigerians: no year between 2018 and 2025 produced a positive real return on a naira savings account. The gap narrowed only marginally in 2019 and 2021, years when oil revenues and relative exchange rate stability kept inflation from accelerating further.

What Does This Mean for the Nigerian Saver in 2026?

The NBS rebasing exercise of January 2026 reset the CPI basket to a 2024 base year, capturing shifts in Nigerian consumption patterns including higher weighting for mobile data and transport. Under the rebased methodology, June 2026 headline inflation printed at 15.91%. The MPR stands at 26.50% following the Monetary Policy Committee's most recent 2026 decision, placing the mandated minimum savings deposit rate at 7.95%. The real return on a benchmark naira savings account therefore remains approximately negative 8 percentage points, even against the lower rebased inflation figure.

Dollar-denominated savers continue to benefit from exchange rate insulation, though the pace of naira depreciation has slowed relative to the dramatic 2022–2024 period. The spread between the CBN official rate and parallel market rates has compressed since the managed float reforms of June 2023, reducing the arbitrage premium that previously inflated street-level dollar returns even further.

The structural lesson of 2018 to 2026 is consistent: holding naira cash in a standard savings account has been one of the most reliable ways to destroy wealth in real terms in Nigeria's recent history. Understanding why requires examining both CBN monetary policy constraints and the structural fiscal deficits that have driven money supply expansion. That is a longer conversation. The numbers, at least, are unambiguous.
