Deniz Yatırım (DenizFX) vs QNB Finansinvest: Which Is More Reliable?

Deniz Yatırım (DenizFX) and QNB Finansinvest are both authorised by the SPK, so both operate under the same 1:10 leverage cap, the same margin rules and the same complaint channels. The regulatory floor is identical.

What separates them is execution: the widest gap in our score is on **Regulation**, where Deniz Yatırım (DenizFX) scores higher. Cost items (spread, commission, overnight swap) are not priced into the score at all — those you must compare on the firms' own fee schedules.

The FX Trust Score is weighted: regulation 35%, complaint resolution 25%, transparency 15%, withdrawals 15% and track record 10%. Between these two the widest divergence is on Regulation.

Complaint counts (Deniz Yatırım (DenizFX): 0, QNB Finansinvest: 0) are reports reaching us, not a market-wide census — a smaller firm with fewer reports is not automatically safer, because the sample is smaller. How every axis is calculated is set out in our methodology.

You do not have to take our score on trust. Verify the firm on the SPK list of authorised institutions; check that the leverage offered does not exceed 1:10; and make sure the domain does not appear in our SPK bulletin archive as blocked.

We do not recommend a broker and we do not accept payment for placement. If you already have a problem with either firm, our complaint guide sets out which authority handles what — and why an SPK complaint alone does not recover your money.
