How an OPR Change Affects Your Home Loan Instalment in Malaysia (2026)

By Jason Lim, REN 84424 · IQI Realty · Checked on 11 November 2026

When Bank Negara Malaysia (BNM) changes the Overnight Policy Rate (OPR), your bank must move its reference rate by the same amount, and if your home loan is on a floating rate your monthly instalment changes with it. BNM kept the OPR at 2.75% on 5 November 2026. From 1 July 2026, banks have up to 60 calendar days to revise your instalment after a rate change, and must tell you at least 7 days before the new amount starts.

What the OPR is, and where it stands in November 2026

The OPR (Kadar Dasar Semalaman) is BNM’s policy interest rate. It is the target rate for overnight lending between banks, and it is set by BNM’s Monetary Policy Committee (MPC). Banks do not lend to home buyers at the OPR, but their retail reference rates are tied to it.

Date	MPC decision	OPR after the decision
9 July 2025	Cut by 0.25 percentage points	2.75%
5 November 2026	No change (final meeting of 2026)	2.75%

I do not forecast rate moves. The useful question is what a 0.25% move would do to your own instalment, which this guide answers.

From the OPR to your instalment: the reference rate chain

Your effective lending rate has two parts: a reference rate that the bank sets for all customers, and a spread that is fixed in your loan agreement. Which reference rate applies depends on when your loan was granted.

Reference rate	Which loans use it	How it moves
Standardised Base Rate (SBR)	New retail floating-rate loans and refinancing from 1 August 2022	Linked only to the OPR. When the OPR changes, the SBR moves by the same amount within 7 working days.
Base Rate (BR)	Floating-rate loans granted before 1 August 2022	Moves by the same amount and at the same time as the SBR.
Base Lending Rate (BLR); Base Financing Rate (BFR) for Islamic	Older loans, from before the BR	Moves with the SBR, by the same amount.

Effective rate = reference rate + spread. If your loan is priced at SBR + 1.25% and the SBR is 2.75%, you pay 4.00%. If the OPR rises by 0.25%, the SBR becomes 3.00% and you pay 4.25%. Your spread stays the same. Under BNM’s March 2026 policy document, the spread on an existing loan can only go up if your own credit risk changes (for example after missed payments). A bank cannot raise it to cover its operating or funding costs or to widen its margin (paragraphs 9.8 and 9.9).

Older BLR loans may show the spread as a minus figure (for example BLR minus 2%). The rule is the same: the reference rate moves, the spread does not.

How quickly the change reaches your statement

Borrowers had noticed that increases often reached them faster than cuts (RinggitPlus, March 2026). BNM’s revised Reference Rate Framework, issued on 27 March 2026, sets the timing out in writing for floating-rate retail loans and financing:

• Reference rate: the SBR, BR and BLR move by the same amount within 7 working days of an OPR change, and banks must take the same time to adjust up as down.
• Instalment, phase 1: from 1 July 2026, the bank must revise your instalment, in the same direction and by the matching amount, within 60 calendar days of the reference rate change. BNM’s good practice is to do it at once or within 30 days.
• Instalment, phase 2: from 2 January 2028, the limit becomes 30 calendar days.
• Notice: you must be told the new instalment and its start date at least 7 calendar days before it takes effect.
• Loans paid through salary deduction by bodies such as Biro Angkasa, the Accountant General or AKPK have up to 90 days.

When your instalment may stay the same

The policy document lists cases where a bank does not have to revise the instalment, but it must tell you why and what it means for you (paragraphs 9.16 and 9.22):

• The change, or the total of several changes, is less than RM10 a month.
• The loan is close to maturity (within about 6 to 12 months of the end).
• The account is under AKPK help, rescheduling or restructuring, legal action, a moratorium or other repayment assistance.
• The loan is still being released in stages and its first full instalment will be recalculated once fully released.
• You ask in writing to keep the old instalment.

If the rate rises and your instalment does not, more of each payment goes to interest, so the loan takes longer to repay or leaves a larger amount at the end. If the rate falls and you keep paying the old amount, the loan ends sooner. The bank’s notice should say which applies.

Worked examples: RM500,000 over 30 and 35 years

Illustrations with made-up round rates, not quotes or current bank rates. The monthly instalment on a standard term loan is worked out with this formula:

M = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1], where P is the loan amount, r is the annual rate divided by 12, and n is the number of monthly payments (360 for 30 years, 420 for 35 years).

Loan of RM500,000	At 4.00%	At 4.25%	Difference
30 years: monthly instalment	RM2,387	RM2,460	about RM73 a month
30 years: total interest	RM359,348	RM385,492	about RM26,144
35 years: monthly instalment	RM2,214	RM2,289	about RM76 a month
35 years: total interest	RM429,827	RM461,577	about RM31,750

First, a 0.25% move changes the instalment by about RM15 a month for every RM100,000 borrowed over 35 years, so a RM300,000 loan moves by about RM45 and an RM800,000 loan by about RM121 at these rates. Second, the longer tenure lowers the monthly payment by about RM173 at 4.00% but adds roughly RM70,500 in total interest. Small monthly gaps add up to tens of thousands of ringgit over the full term.

What happens to an existing loan

Illustration. Say you took that RM500,000 loan over 35 years at 4.00% five years ago. Your balance is now about RM463,700 with 30 years to go. If the rate rises to 4.25%, the bank recalculates the instalment on the balance and the remaining term: about RM2,281 instead of RM2,214, or RM67 more. If the rate falls to 3.75%, it drops to about RM2,148. If the instalment were left unchanged after a rise to 4.25%, the remaining term would stretch from 30 years to almost 32.

Fixed vs floating, and Islamic financing

• Floating rate. Follows the SBR, BR or BLR, so it moves with the OPR as described above.
• Fixed rate. The rate stays the same for the agreed period, so an OPR change does not affect it then. Check your letter of offer for what the loan switches to afterwards.
• Islamic financing. Variable-rate Islamic home financing has an effective profit rate that follows the bank’s reference rate, up to a ceiling profit rate stated in the contract. BNM’s framework covers licensed Islamic banks, and for Islamic retail financing the base financing rate (BFR) is treated like the BLR. See my guide to Islamic home financing for how the ceiling and effective rates work.

Progressive loans for new launches charge interest only on the amount released so far, so during construction a rate change affects a smaller sum. See progressive payments for new launches.

What to do when rates rise

• Read the bank’s notice for the new instalment and start date.
• Update your standing instruction so you pay the new amount. Paying the old amount after an increase leaves arrears that can attract late charges.
• Build a buffer. If you are buying now, check that you could still pay comfortably if the rate were 0.5% to 1% higher. That is a personal stress test, not a forecast. Banks also look at your debt service ratio; see why housing loans get rejected.
• Consider a longer tenure only with care. BNM caps property financing at 35 years (July 2013), and a longer term lowers the instalment but adds interest, as the table shows. Banks also set age limits.
• Compare refinancing if your spread is high compared with current offers, after your lock-in ends and once costs are counted. See refinancing a home loan.
• Get help early if the new amount strains your budget. Talk to your bank about rescheduling before you miss a payment. AKPK (Agensi Kaunseling dan Pengurusan Kredit), set up by BNM in 2006, offers financial counselling and debt management at no fee. See missed home loan payments.

What to do when rates fall

• Check that the cut reaches you. From July 2026 your bank must pass it on within 60 calendar days, in the same way it would pass on an increase, unless an exemption applies and you are told why.
• Decide whether to keep paying the old amount. On a flexi or semi-flexi loan, the extra usually goes straight to the principal; on a basic term loan, check how extra payments are treated. See paying a home loan early and flexi loans.
• Review your spread. A lower OPR does not change it. If yours is well above what new borrowers are offered, compare refinancing.

Raise any complaint about how a rate change was handled with your bank first, then with BNM through its BNMLINK channel.

Notes for foreign buyers

Foreign buyers who borrow in ringgit from a Malaysian bank are covered by the same reference rate rules. If your income is in Singapore dollars, rupiah, rupees or yuan, your instalment in your own currency also moves with the exchange rate, which an OPR change does not control. In Johor, foreign buyers also need state consent and, for most residential property, a minimum price of RM1 million, with some exceptions (New Straits Times, April 2026). See home loans for foreigners and financing a JB property from Singapore.

Where to buy if this matters to you

A smaller loan means smaller rate swings, and area and home type drive the price. Areas buyers often compare:

• Iskandar Puteri: newer townships near the Second Link.
• Bukit Indah and Gelang Patah: established west-side family areas.
• Mount Austin: condos and landed homes near schools.
• Tebrau, Setia Indah and Molek: mature areas with wide subsale choice.
• Skudai, Tampoi and Kempas: older terrace stock.
• JB Sentral and Bukit Chagar: city-centre homes near the RTS Link.

Frequently asked questions

What is the OPR in Malaysia now?

Bank Negara Malaysia kept the Overnight Policy Rate at 2.75% at its final 2026 Monetary Policy Committee meeting on 5 November 2026. The last change was a cut from 3.00% to 2.75% on 9 July 2025.

How long does it take for an OPR change to affect my home loan instalment?

Under BNM’s revised Reference Rate Framework, banks must move the SBR (and the older BR and BLR) by the same amount within 7 working days of an OPR change. From 1 July 2026 they must revise floating-rate instalments within 60 calendar days of that adjustment, falling to 30 days from 2 January 2028, with at least 7 calendar days’ notice.

How much does a 0.25% rate change add to a RM500,000 home loan?

As an illustration, at 4.00% versus 4.25% a RM500,000 loan over 35 years goes from about RM2,214 to RM2,289 a month, around RM76 more. Over 30 years it goes from about RM2,387 to RM2,460, around RM73 more. Your own figure depends on your rate, balance and remaining tenure.

What is the difference between SBR, BR and BLR?

They are reference rates. The Standardised Base Rate (SBR) is used for new retail floating-rate loans and refinancing since 1 August 2022 and moves only with the OPR. Loans taken before then usually follow the Base Rate (BR) or, for older loans, the Base Lending Rate (BLR), which now move by the same amount as the SBR.

Can my bank raise my loan spread when the OPR goes up?

Not for that reason. Under BNM’s policy document, after you sign, the spread on a floating-rate loan can rise only if your own credit risk changes, such as after missed payments. It cannot be raised to cover the bank’s operating or funding costs or to widen its margin.

Does an OPR change affect a fixed-rate home loan?

Not during the fixed period. A fixed rate stays as agreed for the term set in your letter of offer. When the fixed period ends, the loan usually switches to a floating rate, so check your letter of offer for what happens then.

Does the OPR affect Islamic home financing?

Yes, for variable-rate financing. The effective profit rate follows the bank’s reference rate, which tracks the OPR, up to the ceiling profit rate in the contract. BNM’s framework covers Islamic banks too, and for Islamic retail financing the base financing rate (BFR) is treated like the BLR.
