The stock market lost ₦800 billion in a single session on Wednesday. If you don't hold shares, that number can feel like someone else's news. It isn't.

The Nigerian Exchange All-Share Index dipped 1,241.19 points on Wednesday, a 0.50 per cent drop, closing at 245,418.37. Market capitalisation fell by ₦800 billion in a day, landing at ₦158.319 trillion. BUA Foods dropped 10 per cent. Nestlé Nigeria dropped the same. Twenty-five other stocks fell with them.

Pension fund managers hold BUA Foods and Nestlé in the portfolios that pay out retirees every month. A ten per cent drop in a single session doesn't stay on a trading floor. It moves through fund values that ordinary contributors never watch closely enough to notice until the annual statement lands lower than they expected.

The naira, in the same week, has been doing the opposite. It gained against the dollar at the official market, closing at ₦1,375.31 on Tuesday, an improvement of ₦4.80 from Monday. External reserves edged up. The Central Bank held its benchmark rate steady at 26.5 per cent. On paper, the currency side of the economy looks calm.

The naira held steady. The stock market didn't. Two different measures of the same economy, moving in opposite directions in the same 24 hours, and neither one tells you what food will cost this weekend.

If you're the person who checks the naira rate on your phone every morning before sending money home, this is the part that matters. A stable exchange rate this week says nothing about what happens next. It doesn't tell you whether the company that just lost a tenth of its value keeps its prices the same, or passes the loss on the way companies usually do. The market doesn't explain itself to the person buying bread. It just changes the number on the shelf a few weeks later.
