If You Had Invested ₦100,000 In Dollar In 2015, How Much

Renan Filho · Founder & Tech Builder

Quick answer: If you had invested ₦100,000 in dollar in 2015, how much would you have in 2026? The short answer: about ₦1.2 million — but that’s before taxes and fees. Let’s break down the real numbers, compare with local options, and show you where your money actually worked hardest.

Key data for Nigeria (2026-08-10)

The Dollar Investment: From ₦100,000 to ₦1.2 Million

In January 2015, the official exchange rate was around ₦199 per US dollar. Your ₦100,000 would have bought roughly $502. By January 2026, the naira has depreciated to about ₦1,550 per dollar (CBN official rate). That $502 is now worth ₦778,100. But wait — if you had put that money in a dollar-denominated savings account or US treasury bills (which earned about 2-4% annually), your $502 would have grown to about $620 by 2026. At the current rate, that’s ₦961,000. Add a bit of stock market gains (S&P 500 averaged 10% yearly), and you’d have around $1,200 — that’s ₦1.86 million. The point: currency devaluation alone multiplied your money nearly 8x, but smart investing could have made it 18x.

What If You Had Invested in Nigerian Treasury Bills Instead?

Let’s be real: many Nigerians don’t have easy access to dollar accounts. But treasury bills (T-bills) are a local alternative. In 2015, T-bill rates were around 14%. If you rolled over ₦100,000 every 91 days at those rates, by 2026 you’d have roughly ₦380,000 — that’s a 3.8x return, but far below the dollar’s 12.8x. Even with the CBN’s current 22.75% rate, the naira’s slide eats into real returns. For example, ₦500,000 in T-bills at 20% yields ₦100,000 in interest per year — but if the naira drops 30% against the dollar, you’re losing purchasing power. The dollar wins, hands down.

NGX Stocks: The Local Champion?

The Nigerian Exchange (NGX) All-Share Index has had its moments. From 2015 to 2026, it grew from about 28,000 points to 105,000 — a 275% gain. If you had put ₦100,000 in a diversified NGX portfolio (say, Dangote Cement, MTN Nigeria, and Guaranty Trust Bank), you’d have about ₦375,000 today. That’s better than T-bills but still only a third of the dollar’s return. Plus, you’d pay capital gains tax (10%) and dividend withholding tax (10%) on profits. The stock market is good for growth, but it doesn’t hedge against naira devaluation like the dollar does.

The Hidden Costs: Taxes and Inflation

Don’t forget the taxman. If you sell your NGX shares, you pay 10% capital gains tax. Dividends are taxed at 10% withholding. On the dollar side, if you invest via a local fintech app like Bamboo or Chaka, you’ll pay a spread (usually 1-3%) and maybe a management fee. Inflation in Nigeria averaged 15% per year from 2015 to 2026. So that ₦1.2 million in 2026 has the purchasing power of about ₦280,000 in 2015 naira. Still, you’re ahead of the game — but only if you actually sold your dollars at the right time.

Ranking the Best Financial Products in Nigeria (2026)

Based on cost-benefit for the average Nigerian, here’s my ranking: 1st — Dollar-denominated mutual funds via Stanbic IBTC or ARM (best for hedging, low fees, easy entry). 2nd — NGX stocks via GTBank’s InvestNow platform (best for long-term growth, but volatile). 3rd — Nigerian Treasury Bills (best for risk-averse savers, but returns lag inflation). 4th — Fintech apps like PiggyVest (best for automated savings, but interest rates are low). 5th — Fixed deposits with Access Bank (best for short-term, but rates are often below T-bills). Each has its trade-offs: liquidity, risk, and tax implications.

Practical example in Nigeria

₦500,000 in Nigerian treasury bills at 20% yields ~₦100,000 in interest per year

Risks and cautions

Volatilidade do mercado, mudanças na política monetária de Central Bank of Nigeria (CBN) e fatores geopolíticos globais são os principais pontos de atenção para investidores em Nigeria.

Frequently asked questions

Can I still invest in dollars in 2026?

Yes, via fintech apps like Bamboo or through your bank’s domiciliary account, but you’ll need to buy dollars at the official rate, which is often lower than the parallel market.

What’s the minimum amount to start investing in NGX stocks?

You can start with as little as ₦5,000 via GTBank’s InvestNow or Stanbic IBTC’s Stockbroking account.

Are treasury bills still worth it in 2026?

Only if you’re over 50 and want zero risk. For younger investors, the returns don’t beat inflation or the dollar.

Do I pay tax on dollar investments?

You pay capital gains tax on profits if you invest via a Nigerian-regulated platform, but the CBN has been silent on forex gains — check with SEC Nigeria.

What’s the best way to protect my savings from naira devaluation?

Buy dollars or invest in dollar-denominated assets like US stocks or global mutual funds. That’s the only way to keep up with the CBN’s policy.
