Money Market Funds vs Bank Deposits in Turkey
For lira cash, this is the decision most Turkish savers actually make. It is also a comparison that produces the wrong answer unless you handle the tax difference first.
The two instruments
A term deposit pays a fixed rate over a fixed term, is covered by state deposit insurance up to a statutory limit, and is available at any bank. Breaking the term generally forfeits the interest.
A money market fund holds treasury bills, repo and short-dated bank instruments. TEFAS lists 51 of them, all in the lowest risk band. They price daily, settle same or next business day, and compound daily. There is no state insurance and the return is variable rather than promised.
The tax asymmetry
Here is what breaks naive comparisons. Interest on deposits is subject to withholding tax; returns on money market funds are not. So a bank advertising a gross rate and a fund reporting a return are quoting different kinds of number — one before tax, one effectively after.
Comparing them directly overstates the deposit. To put them side by side, express the fund return as the gross deposit rate that would leave you in the same position:
deposit equivalent = fund return ÷ (1 − withholding rate)
That is what the deposit equivalent table computes, updated daily, so you can read a rate your bank has quoted straight against it.
What the tax adjustment does not settle
Being ahead on the adjusted number is not the whole comparison. Three differences survive it:
- Certainty. A deposit rate is contractual. A fund return is what it turns out to be — historically stable for this category, but not promised.
- Insurance. Deposits carry state coverage up to a limit. Funds do not; you hold units in a portfolio of securities.
- Liquidity. Funds can be sold any trading day without penalty. Breaking a deposit early usually costs the interest.
Which of these matters is a question about your circumstances, and this site does not attempt to answer it for you. What it can do is make sure the return figures you are weighing are actually comparable.
Neither instrument solves inflation
The comparison above is relative. Both options can lose to inflation at the same time, and in Turkey they frequently have. Beating deposits is not the same as preserving purchasing power.
Check the CPI row in the benchmark block on any fund page, or read what lira savings actually earn. That is the absolute question, and it is the more important of the two.
