The announcement landed at 22:16 on Wednesday night, Gulf News reporting that the CBUAE “has raised its base rate by 25 basis points to 3.9%”, from 3.65%, “effective Thursday, September 17”. The trigger was in Washington a few hours earlier: the Federal Reserve raised its target range to 3.75% to 4.00%, its first hike since 2023, and the CBUAE’s own statement carried by WAM says the move “was taken following the US Federal Reserve’s announcement today to raise the Interest Rate on Reserve Balances (IORB) by 25 basis points.” The dirham is pegged to the dollar, so this was never in doubt.
What I want to do here is not explain the peg again. It is to answer the question the headline provokes: which of the loans on a normal household’s statement actually reprice, and on what date. The answer is a calendar, not a Thursday.
The base rate is not a rate anyone pays
The 3.9% is the rate on the CBUAE’s Overnight Deposit Facility, the rate banks earn parking money overnight with the central bank. The same statement keeps the rate for banks borrowing short-term liquidity at “50 basis points above the Base Rate”, so 4.4%. Retail loans in the UAE do not price off either number. They price off EIBOR, the interbank rate fixed every working day, plus the bank’s margin. EIBOR anticipates the central bank rather than waiting for it, which is why the gap between the two was already 60 basis points on the twelve-month tenor when I wrote about the base rate versus EIBOR in August.
So the question for a borrower is not “did the base rate move” but “what does the contract say happens when EIBOR moves, and when does it look”.
What the key facts statement says about the review date
UAE banks publish a Key Facts Statement for each loan product under a Central Bank directive issued with the Consumer Protection Regulation. Emirates NBD’s home loan KFS, dated 02/2026, is a good specimen because it spells out the mechanism in one footnote:
“When variable interest rate is linked to EIBOR (The Emirates Interbank Offered Rate) i.e. EIBOR + Fixed Margin, the EMI will change depending on the actual EIBOR rate on the review date. You can choose variable price linked to 1 month or 6 months EIBOR. Variable pricing linked to 1-month EIBOR will be reviewed monthly and variable pricing linked to 6-months EIBOR will be reviewed every 6 months.”
That footnote is the whole story. A mortgage on 1-month EIBOR picks up a rate change within a month. A mortgage on 6-month EIBOR picks it up at the next six-monthly review, which for a loan that last reset in July is January. Mashreq’s home loan KFS, last revised 19 June 2026, uses a third clock: “3 Months EIBOR will be fixed on 1st of every calendar quarter by the Bank”, so a hike in mid-September shows up in the October instalment. The same document adds a detail that matters on the way down: the rate is “3 Months EIBOR + Fixed Margin or the minimum rate (floor rate) whichever is higher”. A floor passes every rise through and absorbs part of every fall. The review date is in the welcome letter. It is the one date worth looking up this week.
Emirates NBD’s KFS also shows what the introductory fixed period does: “Fixed interest rate of 3.99% per annum for 3 years of introductory period”, after which “Variable interest rate will apply”, quoted as 1-month EIBOR of 4.24% plus a 1.99% fixed margin, so 6.23%. A borrower inside those three years is untouched by Thursday. The hike is waiting at the end of the fixed period, along with whatever else EIBOR does in the meantime.
What 25 basis points does to the bank’s own example
The KFS representative example is an AED 800,000 loan over 300 months. The bank’s figures: EMI of AED 4,219 during the 3.99% fixed period, and AED 5,267 once the variable rate of 6.23% applies. The sensitivity box on the same page runs the extremes: if 1-month EIBOR is 8% the EMI is AED 7,264, and at 1.00% it is AED 3,791.
Re-run their example with the variable rate 25 basis points higher, 6.48% instead of 6.23%, and the EMI on AED 800,000 over 300 months comes to about AED 5,392. That is AED 125 a month, AED 1,500 a year, for a quarter of a point, and it arrives on the review date rather than on the announcement. If EIBOR has moved more than 25 basis points by then, and it usually has moved ahead of the central bank rather than behind it, the reset reflects that instead.
None of this is a prediction. It is the arithmetic the bank itself prints, with one input changed.
The loans that do not move at all
This is the part the headlines skip. A plain personal loan is usually fixed-rate, and Emirates NBD’s fixed personal loan KFS says so in one line: “Starting from 4.99% up to 19.99% on reducing balance per annum. The rate will remain unchanged for the loan period.” The tenor is 12 to 48 months. The instalment agreed at disbursal is the instalment until the last month, whatever the CBUAE does. The bank does sell a variable personal loan, and that one reviews on the same monthly or six-monthly schedule as the mortgage, but a borrower who never chose EIBOR pricing has no reset date to look up.
Credit cards are the other non-mover. Gulf News puts it plainly: the base rate increase “does not automatically mean every cardholder will see their credit card rate rise by 25 basis points on Thursday.” Card rates are a monthly percentage set by the bank, not a benchmark plus a margin, and they were already far above anything the central bank moves.
The one line that may improve is the deposit side. The same report notes that people “keeping money in savings accounts or fixed deposits may find banks offering more attractive returns”. In my experience that pass-through is slower and smaller than the lending side, and a fixed deposit booked in August stays at August’s rate until maturity.
Why a company feels the hike in days and a household in months
At the trading company where I work, the finance team will feel this move before most people have finished reading about it. The working-capital facilities that fund a container between supplier payment and customer collection are priced at EIBOR plus a margin on each drawdown, so the next invoice discounted after the announcement carries the new cost. A business has no review date, it reprices every time it borrows.
A salaried household borrows once and then repays on a schedule, so its exposure to a rate change is a short list of dates: the mortgage review date, the end of any fixed period, the maturity of any fixed deposit. Write those three dates down and the base rate stops being news and becomes a diary entry.
A rate hike is not an event on a household’s statement. It is an appointment, and the key facts statement already printed the date.
I keep those three dates as reminders against the loan itself in Masrofna, so the nudge arrives the month before the reset rather than the month after. The 25 basis points is small. Not knowing which month it arrives is what turns it into a surprise.
