If you have a variable-rate mortgage in Dubai, or you are comparing offers before taking one out, you have almost certainly seen the term EIBOR on a bank's rate sheet without a plain explanation of what it does. It is not a marketing term and it is not something your bank invents. It is a published benchmark, and for most residents financing a home in the UAE, it is the single number that decides whether next year's repayment goes up, down, or stays put.
This guide walks through what EIBOR is, who actually publishes it, how a bank turns it into the number on your mortgage offer, what causes it to move, and how to weigh a fixed-rate period against staying variable. Every rate and mechanism below is sourced to the Central Bank of the UAE (CBUAE), the only body with authority over EIBOR and over the base rate that anchors it.
What EIBOR actually is
EIBOR stands for Emirates Interbank Offered Rate. In the CBUAE's own regulatory text, it is defined as the daily reference rate at which a panel of banks are able and willing to access UAE dirham funding, in reasonable market size, for a given tenor, from the UAE money market just before 11:00 local time. In plain terms, it is the going rate at which banks in the UAE lend dirhams to each other, fixed once a day, for a range of loan periods (tenors) from overnight out to one year.
It is not the rate a bank charges you. It is the raw ingredient. Retail products, mortgages, business loans, some savings accounts, are priced off it, but always with something added or adjusted on top, which is covered further down.
Who publishes it, and how it is actually calculated
The CBUAE acts as the official administrator of EIBOR, meaning it oversees the panel, the rulebook, and the governance around the fixing, even though the day-to-day calculation has been run by an external calculation agent (Thomson Reuters, now LSEG) since April 2018. A panel of banks operating in the UAE, nominated by the CBUAE, submit a rate for each tenor every business day.
What actually goes into that submission follows a strict order of preference, sometimes called a waterfall. Panel banks must first use their own real interbank transactions of AED 10 million or more if any occurred in the relevant window; failing that, they fall back to unsecured wholesale deposit data of a similar size; only when neither exists do they fall back to internally documented expert judgment, built from broker quotes, related market instruments like interest rate swaps or repo rates, and their own recent submission history. The intent is to keep the fixing tethered to real market activity rather than a bank's opinion whenever real transactions exist.
EIBOR is published across six tenors: overnight, one week, one month, three months, six months and one year. As of late July 2026, the live CBUAE EIBOR page showed overnight at roughly 3.43%, one month at roughly 3.78%, three months at roughly 3.80%, and one year at roughly 4.15%. These figures move daily and the current fixing for any tenor should always be checked on that page directly rather than taken from a screenshot or a third-party summary, including this one.
How a Dubai mortgage rate is actually built
A variable-rate mortgage in the UAE is priced as a chosen EIBOR tenor, most commonly the one-month or three-month rate, plus a margin the bank adds on top. That margin is the bank's own commercial decision. It reflects its cost of funding beyond the interbank rate, the credit risk of the specific borrower and property, the loan-to-value ratio, and how aggressively that bank is competing for mortgage business at a given time. There is no CBUAE-published or industry-standard margin, and it is not the same across banks, loan sizes, or borrower profiles, so it needs to be confirmed directly with the lender in question rather than assumed from a headline "starting from" rate seen in an ad. What can be compared meaningfully across offers is the margin itself, since the EIBOR component is identical for everyone on any given day.
This structure means two borrowers with the same EIBOR-linked mortgage from the same bank, taken out months apart, can end up paying noticeably different total rates, purely because the EIBOR fixing moved between the two dates. It also means a mortgage advertised as "EIBOR plus a margin" will genuinely change over the life of the loan, in either direction, as EIBOR resets.
Fixed vs variable: how Dubai mortgages are actually structured
Lenders in the UAE typically offer two structures. A variable-rate mortgage tracks EIBOR plus margin from day one and reprices on a set schedule tied to whichever tenor the loan references. A fixed-period mortgage locks in a set rate for an initial window, commonly somewhere between one and five years depending on the bank and product, after which it converts automatically to the standard variable structure, EIBOR plus margin, at whatever the fixings and the bank's margin happen to be at that point. Genuinely fixed-for-the-full-term mortgages exist but are far less common in this market than the initial-fixed-period structure.
None of this pricing structure is set by regulation; it is a commercial product design decision each bank makes. What the CBUAE does regulate is the underwriting discipline behind it. Under the Regulations Regarding Mortgage Loans, lenders are required to stress-test a borrower's ability to service the loan at two to four percentage points above the current interest rate, and specifically, where an introductory or fixed rate applies, banks must stress-test against the rate that will actually apply once that introductory period ends, not the teaser rate itself. The same regulation requires lenders to disclose all fees and the method of calculating interest up front, and it bars changes to loan terms without the borrower's written agreement, with at least two months' notice required for changes to fees or commissions.
What actually moves EIBOR
EIBOR is a market rate, but it does not move independently of UAE monetary policy. The CBUAE sets a Base Rate applied to its Overnight Deposit Facility, and that Base Rate is explicitly anchored to the US Federal Reserve's Interest Rate on Reserve Balances (IORB), because the dirham maintains a fixed exchange-rate peg to the US dollar. In practice, this means that whenever the Fed changes its target rate, the CBUAE typically announces a matching move to its own Base Rate the same day, since holding a currency peg leaves little room to run an independent interest-rate policy.
The CBUAE has been explicit about the mechanism: its own release describes the Base Rate as signaling the general stance of monetary policy and providing an effective floor for overnight money market interest rates in the UAE, with the rate for the CBUAE's own short-term lending facilities set at 50 basis points above it. As of mid-2026 the Base Rate stood at 3.65%, down from higher levels earlier in the cycle, tracking the Fed's cutting cycle over that period. In practice, this floor is indicative rather than absolute: ample dirham liquidity has recently pushed the overnight EIBOR fixing (roughly 3.43% in late July 2026, as noted above) below the 3.65% Base Rate, which shows the "floor" describes the general stance of policy rather than a hard bound the market rate cannot cross.
EIBOR term rates sit above the Base Rate and move with it directionally, but they are not identical to it, because EIBOR also reflects actual dirham liquidity conditions, credit spreads between banks, and demand for term funding in the local market, which can loosen or tighten independent of the policy floor. That is why EIBOR can drift a little ahead of or behind a Base Rate change, and why the different tenors do not always move by exactly the same amount.
What a rate change actually does to your repayment
The mechanics matter more than the headline percentage. Take an illustrative AED 2,000,000 mortgage amortizing over 25 years. At an effective rate of 4%, the standard monthly installment works out to roughly AED 10,557. At 5%, the same loan costs roughly AED 11,692 a month, an increase of about AED 1,135 a month, or over AED 13,600 a year, for a one-percentage-point move. This is a plain amortization calculation for illustration only, not a quoted bank rate, and the actual effect on any specific loan depends on its balance, remaining term, and repayment structure.
For a variable-rate mortgage, that kind of change does not usually hit the day EIBOR moves. Most UAE lenders reprice on a set cycle, commonly monthly or quarterly, matched to whichever EIBOR tenor the loan is linked to, so there is a lag between a fixing move and the change actually landing on your statement. How a rate rise is then applied also varies by lender and by loan contract: some banks adjust the monthly installment directly, while others may hold the installment steady and extend the remaining term instead, within limits set by the loan agreement. Which approach applies to a given mortgage should be confirmed directly with the lender or in the loan contract, since it is a product term rather than something set by regulation.
How to think about a fixed-period offer
A fixed initial period buys certainty. For as long as it lasts, the rate on the mortgage statement will not move even if EIBOR or the Base Rate does, which is valuable if rates are rising or expected to rise, or if a household simply wants a predictable number to budget against for a few years. The trade-off is symmetrical: if rates fall during that window, the fixed borrower does not benefit until the fixed period ends, and breaking a fixed-rate mortgage early, to refinance or to sell the property, typically carries an early-settlement cost that should be checked before signing.
The more important number to focus on is usually not the fixed-period rate itself but what the loan reverts to once that period ends. Since the loan converts to EIBOR plus margin at whatever those two figures are on the day the fixed period expires, a fixed offer with an attractive teaser rate but a wide reversion margin can end up more expensive over the full loan life than a variable rate with a tighter margin throughout. It is worth asking a lender directly which EIBOR tenor the reversion will use, what the margin will be after the fixed period, and whether that margin is guaranteed in the contract or indicative only.
The CBUAE's own stress-test requirement is a useful gut-check here: since lenders are required to test affordability at the post-introductory rate, not the teaser rate, any borrower comparing a fixed-period mortgage should run that same test personally, budgeting for the reversion rate rather than the headline fixed rate, before deciding the initial period's certainty is worth its cost.
FAQ
What is EIBOR in one sentence? It is the daily benchmark rate at which banks operating in the UAE lend dirhams to each other, published across six tenors from overnight to one year, and used as the base for pricing variable-rate mortgages and other loans.
Who sets EIBOR, and can I check today's rate myself? The CBUAE administers EIBOR and a panel of banks it nominates submits the daily inputs. Anyone can check the current fixing for every tenor on the CBUAE's own EIBOR rates page, updated each business day.
Is my mortgage rate exactly the EIBOR figure I see published? No. Banks price mortgages as a chosen EIBOR tenor, usually one-month or three-month, plus a margin the bank sets itself based on its funding cost and the borrower's risk profile. The margin is not published by the CBUAE and varies by bank, so it needs to be confirmed with the lender directly.
What actually makes EIBOR go up or down? Largely UAE monetary policy, which itself tracks the US Federal Reserve. The CBUAE's Base Rate is anchored to the Fed's Interest Rate on Reserve Balances because of the dirham's dollar peg, and EIBOR term rates move with that policy stance, adjusted for actual liquidity and credit conditions in the local interbank market.
Is a "fixed-rate" mortgage in Dubai fixed for the whole loan term? Usually not. Most fixed offers apply for an initial period, commonly one to five years, after which the loan automatically converts to a variable rate of EIBOR plus margin at the prevailing levels. Fully fixed-for-term mortgages exist but are less common. Always confirm the length of the fixed window and the reversion terms before signing.
How often does a variable-rate mortgage in Dubai actually reset? It depends on the loan contract and which EIBOR tenor it references, but resets on a monthly or quarterly cycle are typical. There is normally a short lag between an EIBOR move and it showing up in your installment, and how the change is applied, adjusted payment versus adjusted term, varies by lender and should be confirmed in the loan agreement.
