Portfolio investment flows into Nigeria: Key facts on 2025 and Q1 2026

Foreign portfolio investment is now the main channel for capital entering Nigeria, reaching $19.74 billion in 2025 and $9.86 billion in the first quarter of 2026. These inflows represent more than 85 per cent of total capital importation in 2025 and over 95 per cent in Q1 2026.

How the money flows

A foreign investor, often from the United Kingdom, the United States, or South Africa, sends dollars through an authorised dealer bank in Nigeria. The bank issues a Certificate of Capital Importation (CCI), which later allows the investor to repatriate principal and returns. The dollars are converted into naira at the official rate and used to buy assets.

Most of the money goes into short-term government securities. A smaller portion buys longer-dated Federal Government bonds, and an even smaller share goes into equities on the Nigerian Exchange. The banking sector is the largest recipient because banks act as intermediaries.

What investors are buying

Money market instruments dominate. These include Treasury Bills and Open Market Operation (OMO) bills from the Central Bank of Nigeria. In 2025, they took around $13.8 to 13.9 billion of portfolio flows. In Q1 2026, they attracted $6.50 billion. Investors like the high yields, short tenors of 91 to 364 days, and the backing of the sovereign or central bank.

Bonds come next. Foreign investors bought about $4.89 billion in 2025 and $3.23 billion in Q1 2026. These are Federal Government bonds with longer maturities, offering attractive yields but more interest-rate risk.

Equities receive the smallest allocation. Portfolio equity investment was roughly $1 to 2 billion in 2025 and only about $132 million in Q1 2026. Concerns about liquidity, corporate governance, and converting large sums back into dollars limit foreign appetite for shares.

Risks and the path forward

The biggest risk is hot money. Portfolio capital can enter quickly when yields are high and exit just as quickly if global conditions change or confidence in the naira weakens. Sudden outflows can pressure foreign exchange reserves and the exchange rate. Nigeria's net foreign liabilities rose to $90.2 billion in 2025, partly reflecting these portfolio claims.

The IMF and other analysts have warned that over-dependence on this capital leaves the economy vulnerable. To attract more stable inflows and reduce interest costs, Nigeria needs sustained FX liquidity and exchange rate stability, a credible path to lower inflation, consistent policies, and a better investment climate. Greater engagement with international investors can also broaden the buyer base and support lower borrowing costs over time.

For the naira and Nigerian businesses, these flows offer short-term support for reserves and the exchange rate. But without reforms that encourage longer-term investment, the country remains exposed to sudden reversals that could weaken the currency and raise borrowing costs.
