What Is EIBOR and How It Impacts Mortgage in the UAE

EIBOR is the Emirates Interbank Offered Rate — the benchmark rate at which UAE banks lend to one another, published every business day by the Central Bank. It matters to you for one reason. Almost every variable mortgage in the UAE is priced as EIBOR plus a margin, and almost every fixed mortgage reverts to exactly that when the fixed period ends. So even if your rate is fixed today, EIBOR decides what you pay for most of the loan’s life. This covers what EIBOR is, how the number is actually produced, why it moves, and what happens at your next reset.

What EIBOR is

A reference rate, not a rate anyone charges you directly. It reflects the cost of short-term borrowing between UAE banks, stated in dirhams, and it’s used as the base for pricing mortgages, personal loans, car loans and Islamic Ijara facilities.

The tenors

EIBOR isn’t a single number. It’s fixed across six tenors:

• Overnight
• 1 week
• 1 month
• 3 month
• 6 month
• 12 month

Three-month is the one that matters for mortgages. It’s the most common reference for UAE home loans, though some banks use one-month or six-month. Your offer letter names which one applies to you, and it’s worth checking rather than assuming. The longer the tenor, the higher the rate usually sits, because it prices a longer commitment.

What EIBOR isn’t

It isn’t your mortgage rate. It’s the base. Your rate is EIBOR plus your bank’s margin, and the margin is typically the larger part of what you pay. It also isn’t set by the Central Bank as a policy decision. The CBUAE administers the process; the number comes from the banks.

How EIBOR is actually fixed

Worth understanding, because it explains why the rate behaves the way it does.

The panel

The Central Bank nominates a panel of eight to fourteen banks, selected on size, relevance and the nature of their operations. Only conventional banks can sit on it. Each panel bank maintains a board-approved Interest Rate Submission Guideline governing how it produces its numbers, and must appoint an independent auditor from a list the CBUAE nominates. The Central Bank can carry out special examinations of any panel bank’s submission process.

The waterfall

This is the part that changed in 2018, and it’s what makes EIBOR more robust than the benchmarks that caused problems elsewhere. Panel banks must base submissions on actual transaction data from the previous day wherever possible, rather than on opinion. Where no transactions exist, they follow a defined waterfall, beginning with unsecured interbank transactions above AED 20 million and working down through progressively less direct inputs. The point is that the rate reflects the market where the market exists, and uses a disciplined fallback where it doesn’t.

The trimming

Submissions are collected, then the top and bottom quartiles are discarded and a mean is taken of what remains. That removes outliers in both directions, so no individual bank’s submission can pull the fixing far. It’s a deliberate anti-manipulation design.

Publication, and the value date

Data is collected from the panel after 11:00 UAE time and the fixing is published by 12:00 each business day, to five decimal places. Refinitiv, formerly Thomson Reuters, has acted as calculation agent since April 2018; before that the Central Bank calculated it directly. One practical detail most people miss: EIBOR fixings carry a T+2 value date. A rate published on the 1st applies from the 3rd. So the number on the screen today isn’t the number in effect today, and when a contract refers to “the prevailing EIBOR,” the value date is what matters.

When there’s no fix

If too few panel banks submit to meet the minimum threshold, the day is declared a “no fix” and no rate is published. Rare, but it’s why contracts specify what happens if a fixing is unavailable.

Why EIBOR moves

The dollar peg does most of the work

The dirham has been pegged to the US dollar at 3.6725 since 1997. Holding that peg requires UAE monetary policy to track US policy closely, so when the Federal Reserve moves, the CBUAE base rate follows and EIBOR follows that. The practical consequence: if you want to anticipate your variable rate, watch the Fed. Local commentary matters far less than the FOMC calendar. Transmission isn’t instant. Expect roughly one to two months between a Fed decision and it showing clearly in EIBOR, and longer again before it reaches your payment depending on your reset interval.

Where it’s been

Three-month EIBOR sat around 0.2% at the end of 2021. It rose roughly four percentage points over the following twelve months as the Fed tightened, reaching levels not seen since 2008. It has eased since, and as at the 3 September 2026 CBUAE fixing sat at 4.00%, with one-month at 3.81%, six-month at 4.11% and twelve-month at 4.34%. Check the live figure at centralbank.ae before relying on any published number, including this one. EIBOR changes every business day.

How EIBOR reaches your payment

Three things determine the effect: the margin, your reset interval, and the size of the move.

The margin

Your rate is EIBOR plus a fixed margin set by your bank, quoted as something like “3-month EIBOR + 1.75%”. Current mortgage margins run roughly 0.70% to 2.25%. EIBOR moves. Your margin doesn’t, for the life of the loan. That makes it the single most important number to negotiate, because it survives every rate cycle while EIBOR rises and falls around it.

Your reset interval

Your rate recalculates at the interval in your contract — monthly, quarterly, half-yearly or annually. Quarterly is most common. Shorter intervals mean faster transmission in both directions. A one-month reset passes a cut through quickly and a rise equally quickly. A twelve-month reset insulates you for a year, in either direction.

What a move actually costs

A AED 1,500,000 balance at EIBOR + 1.75% with 22 years remaining: A 50 basis point move in EIBOR changes that payment by roughly AED 443 a month, or AED 5,318 a year. Worth stress-testing your own budget against a one-point rise before choosing variable. You can model any of these on our mortgage calculator.

EIBOR matters even if your rate is fixed

Two reasons, and both catch people out.

The reversion

Most UAE mortgages fix for one to five years and then revert to EIBOR plus a margin. Typical reversion margins are 1.50% to 2.50%, so with EIBOR at 4.00% a reversion lands around 5.50% to 6.50%. A borrower on a three-year 3.95% fix reverting to EIBOR + 2% moves to 6.00% on a date agreed years earlier. On a AED 2 million loan that’s roughly AED 2,100 a month more, for the remaining twenty-two years. The fixed rate is temporary. The margin is permanent. Compare the margin.

The stress test

Affordability is assessed 2 to 4 percentage points above your rate — and where a fixed period applies, against the reversion rate rather than the introductory one. So an attractive short fix doesn’t increase what you can borrow, because the bank is already testing you against EIBOR plus your margin plus the buffer. Our comparison of fixed versus variable mortgages covers the choice, and our guide to current UAE mortgage rates shows where margins and fixed rates currently sit.

EIBOR and Islamic finance

Sharia-compliant mortgages don’t charge interest, but many still reference EIBOR as a benchmark for setting the profit rate on an Ijara facility. The structure differs and the terminology differs. The sensitivity to EIBOR movements is often broadly comparable, so if you’re comparing an Islamic variable product against a conventional one, ask the same question of both: what’s the margin over the benchmark, and how often does it reset.

Something new on the horizon

The Central Bank has been developing DONIA, a new overnight index built from actual interbank market transactions and constructed to international best practice. Two things worth knowing. The CBUAE has said it has no plans to discontinue EIBOR — the two will co-exist, with DONIA serving as an anchor that panel banks can reference in their daily fixings. And at this stage DONIA is not used to price financial products in the UAE. So it isn’t a LIBOR-style transition, and nothing about your mortgage changes. But if your contract ever references a successor rate, this is the context.

What to watch

Federal Reserve decisions. The primary driver, with a one to two month lag. Your reset date. Know when it falls and what tenor applies, so a change doesn’t surprise you. Your margin at reversion. If you’re on a fix, diarise the end date now. Approaching reversion is the moment to compare a buyout, and no 4% transfer fee applies on a switch because the property doesn’t change hands — see our guide to refinancing. Green product pricing. Some lenders price energy-efficient properties differently, covered in green mortgages in the UAE.

Knowing what your margin should be

EIBOR is the same number for everyone. Your margin isn’t, and it’s the part that determines what you actually pay for the next twenty-five years. Current mortgage margins run from roughly 0.70% to 2.25%, and that spread is worth tens of thousands of dirhams a year on a typical loan. We compare across 15+ UAE lenders and look at the margin and the reversion rather than the headline.

Frequently asked questions

What does EIBOR mean?

Emirates Interbank Offered Rate — the benchmark rate at which UAE banks lend to each other, published every business day by the Central Bank and used as the base for pricing mortgages and other loans.

What is the EIBOR rate today?

At the 3 September 2026 CBUAE fixing, three-month EIBOR was 4.00%, one-month 3.81%, six-month 4.11% and twelve-month 4.34%. It changes every business day, so check centralbank.ae for the current figure.

How is EIBOR calculated?

A panel of eight to fourteen banks submits rates for six tenors, based on actual transaction data where available. The top and bottom quartiles are discarded and a mean is taken of the rest. Data is collected after 11:00 UAE time and published by 12:00 to five decimal places.

Who sets EIBOR?

The Central Bank administers it and nominates the panel, but the rate comes from bank submissions. Refinitiv has been the calculation agent since 2018.

Why is EIBOR increasing or decreasing?

Because the dirham is pegged to the US dollar, UAE rates track Federal Reserve policy closely. When the Fed raises or cuts, EIBOR follows with roughly a one to two month lag.

How does EIBOR affect my mortgage?

If you’re on a variable rate, your payment is EIBOR plus your bank’s margin and recalculates at your reset interval. If you’re on a fixed rate, EIBOR determines what you revert to when the fixed period ends.

What is 3-month EIBOR?

The rate for three-month interbank lending, and the most common reference for UAE variable mortgages. Your offer letter specifies which tenor applies to you.

Does EIBOR apply to Islamic mortgages?

Many Sharia-compliant products reference EIBOR as a benchmark for setting the profit rate, even though no interest is charged. Ask about the margin and reset frequency exactly as you would with a conventional product.

What is a no fix?

If too few panel banks submit on a given day, no EIBOR rate is published for that day. It’s rare, and loan contracts specify what applies in that event.
