Today’s money mission
Imagine this situation: Your investment returned 24% this year. A friend's in the UK returned 8%. Nigerian inflation: 22%. UK inflation: 4%.
What you need to know
Dynamic inflation hurdle: when Nigerian inflation was 12% (2015), a 15% nominal return generated real wealth. When inflation reached 33% (2024), that same 15% return destroyed real wealth. The hurdle is not static — it tracks inflation. This is why Nigerian investors must monitor inflation as actively as they monitor investment returns. A return that built wealth last year may be destroying it this year.
Real-life example
Real-life money moment: You hold a diversified Nigerian portfolio: 40% equities (25% nominal return), 30% FGN bonds (18% nominal), 20% real estate (22% nominal), 10% T-bills (20% nominal). Current inflation: 26%. Calculate the portfolio's weighted real return. — Portfolio real return at 26% inflation: weighted nominal 21.8% − 26% = −4.2% real. Equities (25%) and real estate (22%) individually beat 26% inflation barely or not at all. Bonds (18%) and T-bills (20%) are below 26% — dragging down the aggregate. At 26% inflation, even an equity-heavy portfolio struggles. The lesson: during very high inflation periods, the entire portfolio must shift toward higher-returning assets to maintain positive real returns.
