Direct answer: On Wednesday the US Federal Reserve left its policy rate unchanged at 3.75% to 4.00%, and within the hour the Central Bank of the UAE held its Base Rate at 3.90%. If you hold a variable-rate mortgage in the UAE, that does not mean your instalment is frozen. Your loan does not price off the Base Rate. It prices off EIBOR, the interbank benchmark, plus a margin written into your facility letter, and it only changes on your contractual reset date. Three-month EIBOR has spent September and October fixing well above the Base Rate, roughly 4.2% to 4.4% against 3.90%, after sitting below 3.7% at the end of May. So a household whose fixed period ended this autumn, or whose reset falls in November or December, can see a higher instalment in a month when the headline says “no change”. This article explains the three rates that sit behind one mortgage, why the benchmark drifts when policy stands still, how to find your own reset date, and what to do with the planning window a hold gives you.
What actually happened this week, and what did not
The Federal Open Market Committee voted on 28 October to keep the federal funds rate in a range of 3.75% to 4.00%, where it has been since a quarter-point increase in September. Two of the twelve voters dissented in favour of a further rise. The statement described inflation as still elevated and said the committee wants the accumulation of more information before deciding its next step. The Chairman’s press conference gave little guidance on timing.
Because the dirham is pegged to the dollar, the Central Bank of the UAE moves with the Fed. It confirmed the same afternoon that the Base Rate on its Overnight Deposit Facility stays at 3.90%, and that the rate for borrowing short-term liquidity remains 50 basis points above that.
That is the complete list of what changed in policy terms: nothing. What did not stop moving is the market rate that most UAE mortgages are actually tied to. It is worth being precise about the difference, because the gap between “the central bank held” and “my instalment held” is exactly where households get surprised.
We are not going to tell you what the Fed does in December. Nobody honestly can, and this is not the place for forecasts. The point of this piece is narrower and more useful: whatever the next decision is, a well-run household should already know how it would hit their mortgage, on what date, and by how much.
Three rates, one mortgage
Most UAE borrowers think about one rate: the one on their facility letter. In practice three different rates stand behind it, and they do not move in lockstep.
The Base Rate: what the central bank sets
The CBUAE Base Rate is the rate the central bank pays on overnight deposits from banks. It anchors the whole system and, through the peg, it follows the Fed. It is the number in the headlines. It is almost never the number in your mortgage contract.
EIBOR: what banks charge each other
The Emirates Interbank Offered Rate is the benchmark at which banks are prepared to lend dirhams to one another for a given term: one week, one month, three months, six months, one year. The Central Bank publishes the fixings every business day. Almost every variable-rate mortgage in the UAE is priced as EIBOR for a stated tenor, plus a margin. Three-month EIBOR is the most common reference, though one-month and six-month contracts exist.
EIBOR is a market price. It reflects the Base Rate, but it also reflects how much liquidity banks have, how hard they are competing for deposits, what the market expects the Base Rate to be over the life of that tenor, and seasonal pressures around quarter-ends and year-end. That is why it can rise when the Base Rate is flat, fall when the Base Rate is flat, and move by more or less than the Base Rate when policy does change.
Your contractual rate: EIBOR plus margin, subject to a floor
Your facility letter typically defines the rate as the relevant EIBOR tenor plus a fixed margin, for example “three-month EIBOR plus 1.50% per annum”. It usually adds a minimum rate, often called a floor, below which the all-in rate cannot fall regardless of the benchmark. It states how often the rate is reviewed and on what basis the benchmark is read. That document, not the news, governs what you pay.
Why EIBOR drifts when the Base Rate stands still
Between the end of May and the middle of October, the Base Rate rose once, by 25 basis points, in September. Over the same stretch three-month EIBOR rose by roughly half a percentage point, from below 3.7% to a band around 4.2% to 4.4%. The benchmark moved about twice as far as policy did. Four forces explain that, and all four are ordinary.
- Expectations. A three-month rate is a price for money over the next ninety days. If the market thinks policy might be higher at some point in that window, the three-month fixing carries some of that before any decision is taken. The fact that two FOMC members voted for a rise this week is the kind of information that gets priced into a term rate immediately, whether or not the rise ever happens.
- Liquidity. When deposits are growing more slowly than lending, banks pay more to attract and retain funds, and interbank rates rise. The UAE has seen strong credit growth and heavy property-related lending through 2025 and 2026, which tightens the system at the margin.
- Deposit competition. Banks competing for large corporate and retail deposits lift their own cost of funds. EIBOR is the visible edge of that competition.
- Calendar effects. Quarter-end and year-end balance sheet management regularly pushes short-term rates up for a few weeks. A reset date that falls in late December reads a benchmark that often includes a seasonal premium.
None of this is a sign of stress. It is the normal behaviour of a term benchmark. But it means the question “did the central bank move?” is the wrong question for a mortgage holder. The right question is “what will my benchmark read on my reset date, and when is that date?”
The reset calendar: when your instalment actually changes
A variable-rate mortgage does not reprice continuously. It reprices on a schedule written into the facility. Understanding that schedule is the single most useful thing you can do this week.
If you are still inside a fixed period
Nothing about this week’s decision touches your instalment until the fixed period ends. What matters is the date it ends and the clause that says what happens next. Most facilities revert to a variable rate defined as EIBOR plus a margin, and the margin after the fixed period is often different from the margin that was used to set the fixed rate. Many borrowers who fixed in 2023 or 2024 are reaching the end of those periods now and through 2027. The reversion is the moment of maximum change, because it combines a benchmark that may have moved and a margin that may be new.
If you are already variable
Your facility will state a review frequency. Quarterly reviews read the three-month benchmark; semi-annual and annual reviews read the six-month or twelve-month fixing, or sometimes the three-month fixing on a set date. The instalment is recalculated on the review date using the benchmark observed on or shortly before that date, and the new instalment applies from the next payment. If your review falls in the first week of November, the fixings of late October decide your next quarter. If it falls in late December, the year-end fixings do.
The floor and the ceiling
Two clauses deserve a careful read. The floor sets the minimum all-in rate. If your floor is, say, 3.50% and EIBOR plus margin comes to 5.70%, the floor is irrelevant today, but it matters in any later period of falling rates because it stops your instalment from falling all the way with the benchmark. A cap, where one exists, works the other way and limits how far the rate can rise in a review period or over the life of the loan. Caps are less common in UAE retail mortgages than floors, and if you have one, you should know exactly how it is worded.
A worked example: the hold that still cost AED 400 a month
The figures below are illustrative. They do not describe any specific bank’s pricing. Use them to understand the mechanics and then substitute your own facility terms.
Assume a mortgage balance of AED 1,500,000 with twenty years remaining, priced at three-month EIBOR plus 1.50%, reviewed quarterly, with a floor of 3.50% that is not currently binding.
| Illustrative scenario | Base Rate | Three-month EIBOR (approx.) | All-in rate (EIBOR + 1.50%) | Monthly instalment | Change vs. May per month | Change vs. May per year |
|---|---|---|---|---|---|---|
| Reset read in late May 2026 | 3.65% | 3.70% | 5.20% | AED 10,066 | 0 | 0 |
| Reset read in October 2026, policy on hold | 3.90% | 4.20% | 5.70% | AED 10,488 | +AED 423 | +AED 5,072 |
| Benchmark drifts a further 25 bp, no policy change | 3.90% | 4.45% | 5.95% | AED 10,703 | +AED 637 | +AED 7,649 |
| Benchmark drifts a further 50 bp, no policy change | 3.90% | 4.70% | 6.20% | AED 10,920 | +AED 854 | +AED 10,253 |
Instalments are calculated on a standard amortising basis for a 240-month remaining term and rounded to the nearest dirham. Benchmark levels are approximate and illustrative; the Central Bank publishes the official fixings daily. Your facility letter governs.
What the table is saying
Read the first two rows together. The Base Rate moved by 25 basis points between May and October. The instalment moved by AED 423 a month, which is what a 50 basis point change produces on this balance, because the benchmark moved twice as far as policy. A borrower who watched only the central bank would have budgeted for half the actual change.
Now read rows three and four. They assume no further policy change at all, only continued drift in the benchmark of the kind that happens when a market is debating the next move. The instalment rises by a further AED 215 to AED 430 a month. On an annual basis the full range from row one to row four is a little over AED 10,000, on a mortgage whose owner would be entitled to say “rates have barely changed since the summer”.
That is the whole argument in one table. A hold is a policy fact. Your instalment is a contractual fact. They are related but not the same, and the difference is measured in dirhams each month.
What a hold is for: ninety days of planning time
A central bank pause is not a pause button on your mortgage. It is, however, something more useful: a window in which the inputs are known and you have time to act before the next data point lands. Here is how we would use it, in the order a treasury desk would.
1. Find the three dates
Open the facility letter, or ask your bank for a statement of terms, and write down three dates: the end of any fixed period, the next rate review date, and the date the revised instalment takes effect. If you cannot find them within fifteen minutes, that is itself a finding. Most of the households we speak to who were surprised by an instalment change did not know their review date.
2. Write down the formula
Benchmark tenor, margin, floor, cap if any, and the exact day the benchmark is observed. Then look up the current fixing for your tenor on the Central Bank’s published EIBOR page and compute your all-in rate today. That is the number your next instalment is likely to be built on if nothing changes between now and the review date.
3. Stress the instalment, not the rate
Take your balance and remaining term and calculate the instalment at today’s benchmark, at today’s benchmark plus 50 basis points, and plus 100 basis points. You are not predicting any of those. You are measuring whether your monthly budget absorbs each of them without touching reserves. If the plus-100 case still fits inside your 50% debt burden ratio and your household cash flow, you can stop worrying and simply note the date. If it does not, you have identified the gap while there is still time to close it.
4. Check the buffer against the reset, not the calendar
A cash reserve sized as “three months of instalments” should be sized on the stressed instalment, not the current one. Recalculate it. The difference is usually small in dirhams and large in peace of mind. Our earlier piece on rate reviews and cash-flow buffers walks through the method.
5. Decide what you would do under each outcome
Write three short lines: if the benchmark is flat at my review, I do X; if it is 50 points higher, I do Y; if it is 50 points lower, I do Z. Possible actions include leaving the loan alone, adjusting discretionary spending for a quarter, asking the bank about a fixed-rate option at reversion, making a partial prepayment within the regulatory early settlement fee cap, or restructuring the tenor. Having the answers written before the review date turns a surprise into a procedure. Our piece on overpaying versus holding cash covers the prepayment decision in more detail.
Fix or float at reversion: how to think about it without forecasting
Borrowers reaching the end of a fixed period this quarter face a familiar question, and the honest answer does not depend on guessing the Fed. It depends on three things you can measure.
The price of certainty. A new fixed rate will be quoted at a level that reflects where the market thinks rates will be over the fixed term. If that quote is above the current variable rate, you are paying a premium for predictability. If it is at or below, the market is paying you to take certainty. Either way, the premium is a number, not an opinion.
Your tolerance for variance. A single-income household with a tight debt burden ratio and a small reserve values a known instalment more than a dual-income household with a large reserve. That is not a judgement about the market; it is a judgement about the household. Our earlier work on single-income stress testing is relevant here.
Your horizon. If you expect to sell, refinance or substantially prepay within the fixed term, the exit terms of the fixed option matter more than the rate. Read the early settlement clause and compare it with the regulatory cap, which limits early settlement fees to the lower of 1% of the outstanding balance or AED 10,000 under the Central Bank’s mortgage regulations.
Put those three together and the fix-or-float decision usually makes itself. What it never requires is a view on December. We wrote about the discipline of refinancing earlier in the year, and the principle has not changed: the decision should survive being wrong about the market.
Owner-occupier and landlord: the same hold, different arithmetic
For an owner-occupier, the reset is a budget question. The instalment competes with school fees, rent on a second home, car finance and savings. The debt burden ratio sets an outer limit at 50% of income, but the practical limit is lower, because a household that is at 50% has no room for the next reset. Our explainer on the 50% ceiling sets out how banks compute it.
For a landlord, the reset is a cover question. The instalment is meant to be paid by rent, and this autumn Dubai rents in many apartment districts have been resetting downward at the same time as benchmarks have drifted upward. We covered the mechanics of that squeeze in detail in this week’s landlord guide. The short version is that the gross cover ratio flatters, the net cover ratio tells the truth, and a reset date that lands between a tenant’s notice and a new lease is the worst possible timing. Knowing the date lets you avoid it being a surprise.
Three mistakes we see households make after a hold
Treating the headline as the contract. “Rates were held” becomes “my instalment is safe”. The two are only the same if your benchmark is flat on your review date, and this autumn it has not been.
Waiting for the next decision before planning. The December meeting is a date on the Fed’s calendar. Your review date is on the bank’s calendar. If yours comes first, waiting for December means planning after the fact.
Confusing a pause with a peak. Nobody knows whether this hold is a pause before a rise, a plateau, or the start of a turn. Two committee members voted for a rise this week; the majority chose to wait. Both positions were reasonable. A household plan that works in all three cases is the only one worth having.
Where structured solutions sit in this conversation
Everything above is about understanding and managing a conventional variable mortgage. For some households that is enough. For others, particularly where the instalment is close to the debt burden limit, where income is lumpy, or where a property is held for rent, the question becomes whether the repayment profile itself can be shaped to fit the household rather than the other way round. That is the territory Money Protects Capital works in from DIFC: structured approaches to mortgage cash flow that may help eligible and suitable customers, always subject to documentation, bank approval, market conditions and regulation. Whether any such approach fits a given situation is something that has to be assessed properly, not assumed.
If you would like to explore that assessment, or simply want help finding your reset date and building the three-line plan above, Monidr, MPCL’s 24/7 AI advisor, is the place to start the conversation.
Frequently asked questions
The Central Bank held the Base Rate at 3.90%. Will my mortgage instalment stay the same?
Not necessarily. UAE variable mortgages are priced off EIBOR plus a margin, not off the Base Rate, and they change only on the review date in your facility letter. Three-month EIBOR has been fixing roughly 30 to 50 basis points above the Base Rate through September and October, and about half a point above its late-May level. If your review falls in the coming weeks, your instalment can rise even though policy did not change.
How do I find out which EIBOR tenor and margin my mortgage uses?
It is written in your facility letter or offer letter, usually in the pricing or interest clause. If you cannot locate it, your bank’s relationship team can provide a statement of terms. You want four items: the benchmark tenor, the margin, the floor and the review frequency with its observation date.
Why did EIBOR rise more than the Base Rate this year?
EIBOR is a market rate for a term, so it carries expectations about future policy, the state of bank liquidity, deposit competition and seasonal calendar effects. When markets are debating whether the next policy move is a rise, term rates tend to carry some of that before any decision is made. The gap between EIBOR and the Base Rate widens and narrows over time; it is not fixed.
My fixed period ends in December. Should I fix again or go variable?
That depends on the premium the bank quotes for certainty, your household’s tolerance for a changing instalment, and how long you expect to hold the loan. It does not require a view on where rates go next. Compare the fixed quote with your variable formula, stress the variable instalment by 50 and 100 basis points, check the early settlement terms against the regulatory cap, and choose the option that your budget survives in every case. A suitability conversation with your bank or an independent adviser is worth having before the reversion date.
Is there anything I can do if the stressed instalment does not fit my budget?
Yes, and the options are wider before the review date than after it. They include adjusting discretionary spending for a quarter, a partial prepayment within the fee cap, asking about a longer tenor or a fixed option at reversion, and, for some households, exploring whether a structured repayment profile could be suitable. Each is subject to eligibility, documentation and bank approval. The common thread is acting while the inputs are known rather than after the instalment has changed. Our piece on payment deferment in the UAE explains what is and is not typically available.
