EIBOR explained: how it sets your UAE mortgage rate

If you have ever seen a UAE mortgage offer priced as "3M EIBOR + 1.75%" and wondered what that actually means for your monthly payment, this is the mechanic behind almost every variable-rate home loan sold in the country. Get this wrong and you can misjudge your worst-case instalment by hundreds of dirhams a month, which matters most in the years just after a fixed period ends.

What is EIBOR and who publishes it?

EIBOR stands for the Emirates Interbank Offered Rate. It is the rate at which UAE banks are willing to lend to one another, published daily by the UAE Central Bank across several tenors: overnight, 1-week, 1-month, 3-month, 6-month and 12-month. Banks use it as the reference point for pricing everything from corporate loans to your home finance, adding their own margin on top to cover funding cost and risk.

The Central Bank also publishes a separate CBUAE Base Rate, which some banks use as an alternative reference for certain products instead of EIBOR. The two move together in practice because both track the same underlying monetary policy stance, but your offer letter will name one specifically, and that is the figure you should track, not a generic "UAE interest rate" quoted in the news.

1-month vs 3-month vs 6-month EIBOR

Most UAE variable mortgages reprice off either 1-month or 3-month EIBOR, with 3-month being the more common reference for retail home loans. The tenor determines how often your instalment can change, not how the rate is calculated. This is a distinction almost no competitor guide draws clearly, and it is the one that decides how quickly you feel any rate movement, up or down.

A borrower on 3-month EIBOR who expects rates to fall will feel the benefit sooner than one on a 6-month or 12-month reset, because their next repricing date arrives faster. The reverse is also true if EIBOR is rising: a 1-month tenor exposes you to the next move within weeks, while a 12-month tenor insulates your instalment for up to a year, for better or worse depending on which way rates are heading when you sign.

A common misconception about "variable" rates

Many borrowers assume a variable-rate mortgage recalculates every single month because the word "variable" implies constant movement. In practice, the loan only reprices on its contractual reset date, tied to whichever EIBOR tenor your offer names. If your loan resets quarterly, your instalment is fixed for that three-month block even though EIBOR itself is published, and can shift, every business day in between.

How EIBOR plus margin becomes your mortgage rate

Your all-in variable rate is simply the published EIBOR figure for the relevant tenor plus the bank's contractual margin. Margins are not capped by regulation; they are set individually by each lender and disclosed in the Key Facts Statement. As an illustration, typical margins on UAE variable home loans run roughly 1.25% to 2.00% over EIBOR, though your own margin depends on loan-to-value, salary transfer and employer.

1. 1Check the current published EIBOR figure for the tenor named in your offer letter.
2. 2Add the bank's disclosed margin from the Key Facts Statement.
3. 3That sum is your rate until the next reset date on that tenor.
4. 4At each reset, the calculation repeats using the newly published EIBOR figure.

Why two banks quoting the same margin can still differ

Two offers can both read "3M EIBOR + 1.75%" and still cost differently across the loan term, because the reset date, any rate floor written into the contract, and the fees bundled into the arrangement all vary. Some banks apply a minimum floor rate below which the loan will not price even if EIBOR falls sharply; this is disclosed in the fine print of the Key Facts Statement and is worth asking about explicitly before you sign.

Why EIBOR moves with the US Federal Reserve

Many borrowers assume EIBOR is a purely local number set at the UAE Central Bank's discretion. In practice it tracks the US Federal Reserve's policy rate closely, because the dirham is pegged to the US dollar at AED 3.6725. When the Fed raises or cuts, the UAE Central Bank typically mirrors the move to protect the peg, and EIBOR follows within days. This is why UAE mortgage pricing is ultimately a US interest rate story as much as a local property market one, and why property market headlines about Dubai supply and demand tell you almost nothing about where your rate is heading.

What happens when your fixed period ends

A fixed-rate mortgage in the UAE is not fixed for the whole term. It is fixed for an introductory period, commonly one to five years, and then reverts to a variable rate: the bank's margin plus EIBOR at that time. The reversion margin is disclosed upfront in the Key Facts Statement, but the EIBOR component is unknown until the reversion date arrives. This is the single most overlooked cost in UAE mortgage shopping, and it is a misconception that trips up a large share of first-time buyers, who read "fixed rate" and assume it means fixed for the full 25-year term.

How to stress-test your reversion instalment before you sign

Take the reversion margin printed in your Key Facts Statement and add it to the highest EIBOR figure your bank or broker can show you from the last full rate cycle, roughly the mid-to-high 4% range during 2023's peak. If you can comfortably afford the instalment at that combined rate, the reversion risk is manageable. If it stretches your budget noticeably beyond your fixed-period payment, a longer fixed term or a lower LTV to start is usually the safer structure.

Worked example: a 1 percentage point EIBOR move

Take a AED 2,000,000 loan over 25 years on a variable rate. If EIBOR plus margin sits at 4.00%, the instalment is roughly AED 10,558 a month. If EIBOR rises by 1 percentage point, taking the all-in rate to 5.00%, the instalment climbs to roughly AED 11,696 a month, an increase of about AED 1,138 monthly, or over AED 13,600 a year. Over a 25-year term that single percentage point can add more than AED 340,000 in total interest if it persists, which is why the reversion margin deserves as much scrutiny as the headline fixed rate when you first compare offers.

Fixed vs variable: which UAE banks offer what

Emirates NBD's indicative floor sits around 3.89% fixed, with most other panel banks pricing roughly 0.05 to 0.10 percentage points above that for comparable profiles. Nearly every bank on the panel offers both a fixed introductory period and a variable EIBOR-linked product, but margins and reversion terms vary meaningfully between lenders, which is exactly why the headline rate alone is a poor way to compare offers.

Where most EIBOR explainers fall short

Most articles online show a single current EIBOR snapshot and present it as though it were fixed and current indefinitely, without a clear timestamp or a reminder to re-check it. Others explain the rate-plus-margin arithmetic well but never show what a 1 percentage point move actually does to a real monthly instalment, and almost none separate the practical effect of a 1-month tenor from a 3-month or 6-month tenor on how fast your reversion date arrives. Treat any EIBOR percentage you read, including the ones in this article, as a point-in-time illustration, confirmed against the UAE Central Bank's own published feed on the day you act.

As an illustration, third-party aggregators in mid-2026 quoted 3-month EIBOR around 3.85%–3.91% and the CBUAE Base Rate around 3.65%. Both figures should be read as snapshots, not as current fact, because they change with every UAE Central Bank publication; the only authoritative source is the Central Bank's own EIBOR page, updated daily, and that is what your bank references when it prices your loan.

It also helps to know who sets the number in the first place. EIBOR is calculated from submissions by a panel of contributing UAE banks, each estimating the rate at which they could borrow unsecured funds from other banks for a given tenor, on a given day. The Central Bank collates these submissions, trims outliers and publishes the resulting benchmark, which is why EIBOR can differ slightly from what a single bank's own internal cost of funds would suggest.

How to track and compare EIBOR-linked offers

The practical approach is to stop comparing headline rates in isolation and instead compare four numbers side by side: the fixed rate, the length of the fixed period, the reversion margin over EIBOR, and any arrangement fees. Lenddoo compares 18 or more UAE banks against these criteria at once and charges the borrower AED 0, because the fee is paid by the lender once a file is placed.
