Ah, I see exactly what’s happening. Let’s break this down carefully, because the differences you’re noticing aren’t necessarily a problem—they’re usually about interest crediting frequency, not the actual return.

1. How Money Market Funds (MMFs) Work

MMFs invest in very short-term instruments (treasury bills, commercial papers, etc.).

They accrue interest daily, meaning your money is technically earning returns every day.

However, the fund may not “credit” that interest to your account daily. Crediting is when you actually see the interest reflected in your balance.

2. Crediting vs. Accrual

UCL (updates every 2 days): This fund seems to credit accrued interest more frequently—almost daily. You see your balance grow more visibly, and it compounds faster.

Invest Naija (updates every 4–5 days): The interest is likely still accruing daily behind the scenes, but the fund consolidates it and posts it every few days. So your daily returns are being earned; you just don’t see them immediately.

⚠️ This is common with MMFs. The frequency of posting interest doesn’t change your overall yield, only the appearance of growth and the compounding speed.

3. Why Funds Delay Credit

Operational efficiency: Posting interest every day is more resource-intensive.

Regulatory requirements: Some funds are only required to calculate and credit interest weekly or monthly.

Investor type: Some funds cater to large institutional investors and batch-update balances periodically.

4. Should You Close Your Account?

Not necessarily. Closing based solely on posting frequency may mean losing a good yield unnecessarily.

Check the fund’s published yield (Daily or Annualized). If the annualized return is comparable to other funds, your money is still growing at the correct rate.

If daily visibility is very important to you for tracking or reinvestment, then switching to a fund with daily posting is reasonable.

✅ Key Tip

Look at the daily yield rate or annualized percentage yield (APY), not how often it posts.

Compounded interest matters more over time than posting frequency.

If you want, I can calculate the actual impact of posting every 2 days vs 5 days for the same principal so you can see whether the delay actually affects your returns in a meaningful way.
