SAMA’s Housing Role: Architecting Saudi Arabia’s Mortgage Market
The Saudi Central Bank (SAMA) serves as the primary architect of Saudi Arabia’s mortgage market infrastructure. While not a housing agency per se, SAMA’s decisions on interest rates, prudential regulations, and capital market supervision have the most direct impact on housing affordability and accessibility of any single institution. Every mortgage contract signed in the Kingdom — 108,795 new residential mortgage contracts in 2025 alone, worth SAR 80.42 billion — operates within the regulatory framework that SAMA designs and enforces. The central bank’s influence extends from the macro level (monetary policy that determines the cost of money) through the institutional level (supervision of banks, finance companies, and SRC) to the individual borrower level (LTV and DTI limits that determine how much a family can borrow and on what terms).
Institutional Authority and Mandate
SAMA, established in 1952 (1372 AH) as one of the oldest central banks in the Gulf region, holds the full spectrum of central banking responsibilities: monetary policy, financial supervision, payment systems, currency management, and financial consumer protection. Its housing-related role emerged organically as the Saudi mortgage market grew from a marginal financial product to one of the most significant asset classes in the banking system.
The central bank’s authority over housing finance derives from its licensing power over banks and finance companies (no institution can originate mortgages without SAMA’s licence), its prudential rulemaking authority (setting the capital, risk, and lending standards that govern mortgage portfolios), and its monetary policy decisions (setting the benchmark interest rates that determine mortgage pricing). SAMA also oversees the insurance sector, including mortgage protection insurance products, and the payment systems through which mortgage payments flow.
Monetary Policy and the Rate Trajectory
SAMA’s six consecutive rate cuts between August 2024 and December 2025 reduced the repo rate from 5.50 percent to 4.25 percent, directly lowering the cost of real estate financing for millions of Saudi families. The sequence proceeded as follows: a 50-basis-point cut in September 2024 (to 5.50 percent repo, 5.00 percent reverse repo), followed by 25-basis-point cuts in September 2025 (to 4.75 percent), October 2025 (to 4.50 percent, the lowest in nearly three years), and December 2025 (to 4.25 percent, the lowest in over three years). Total rate reduction since August 2024: 100 basis points.
The rate trajectory is mechanically linked to the US Federal Reserve through the SAR-USD peg, meaning Saudi monetary policy cannot be independently calibrated for domestic housing conditions — a structural constraint with significant implications. When the Federal Reserve raises rates to combat US inflation, SAMA must follow, even if the Saudi housing market would benefit from lower rates. Conversely, when the Fed cuts rates, SAMA can pass through the benefit to Saudi borrowers, as it did throughout the 2024-2025 cutting cycle.
Since December 2025, SAMA has maintained key interest rates unchanged, providing policy stability. Jadwa Investment expects demand for mortgage financing to gradually improve during 2026, supported by the cumulative effect of the rate cuts and greater availability of housing options.
The impact of rate policy on mortgage affordability is substantial. On a SAR 500,000 mortgage (the maximum amount eligible for REDF profit coverage), a 100-basis-point reduction in the lending rate translates to approximately SAR 5,000 in annual savings — meaningful for families at the income levels targeted by the housing programme. For the total outstanding real estate loan book of SAR 951 billion, the aggregate annual savings from the rate reduction cycle run into billions of riyals.
LTV and DTI Prudential Framework
SAMA’s LTV and DTI regulations define the boundaries of mortgage lending in Saudi Arabia, balancing the national homeownership objective against financial stability imperatives.
Loan-to-Value (LTV) Ratios. SAMA increased the maximum LTV from 85 percent to 90 percent for first-time homebuyers in 2018, reducing the required down payment from 15 percent to 10 percent. This single regulatory change — reducing the upfront cash barrier by one-third — was one of the most significant policy enablers of the homeownership surge from 47 percent (2016) to 65.4 percent (end of 2024). For REDF beneficiaries purchasing properties valued at SAR 800,000 or less, the down payment is further reduced to 5 percent through the Dhamanat guarantee programme, which absorbs the additional 5 percent risk. SAMA’s regulatory framework explicitly accommodates this government-backed guarantee, treating Dhamanat-guaranteed loans as meeting the 90 percent LTV standard despite the borrower contributing only 5 percent equity.
Debt-to-Income (DTI) Ratios. The standard DTI limit requires that monthly credit obligations not exceed 55 percent of total monthly income. For Ministry of Housing or REDF mortgage beneficiaries, the DTI limit is relaxed to 65 percent — a 10 percentage point expansion that significantly increases the borrowing capacity of subsidy-eligible families. A family earning SAR 14,000 monthly can carry up to SAR 9,100 in monthly credit obligations under the programme DTI, compared to SAR 7,700 under the standard limit — a 18 percent increase in borrowing capacity that translates directly into the ability to purchase a more suitable home.
These prudential parameters represent a calibrated compromise between accessibility and stability. Lower LTV requirements would reduce bank risk but exclude more families from homeownership. Higher DTI limits would allow more borrowing but increase default risk. SAMA’s current framework — 90 percent LTV standard (95 percent with guarantee), 55 percent DTI standard (65 percent for programme participants) — reflects the consensus position as of 2025, though the parameters are subject to periodic review as market conditions evolve.
Banking System Exposure and Concentration Risk
Real estate lending now accounts for nearly 30 percent of total bank credit, creating concentration risk that SAMA monitors through its prudential framework. The growth trajectory has been extraordinary: from approximately SAR 200 billion in 2018 to SAR 951 billion by end of 2025 — a nearly fivefold increase in seven years. This growth rate is among the fastest mortgage market expansions globally, driven by the combination of government subsidies, regulatory liberalisation, and strong housing demand.
SAMA’s quarterly monitoring data shows the progression: SAR 922.2 billion at end of Q1 2025, SAR 932.8 billion at end of Q2 2025, reaching SAR 951.3 billion by year-end — a 7.7 percent rise during 2025. The 2030 target of SAR 1.3 trillion implies continued growth of approximately SAR 350 billion over the next four years, which would further increase real estate’s share of total bank credit unless the overall credit book grows proportionally.
The concentration risk is mitigated by several factors. Government subsidies (through REDF) reduce borrower payment burden, lowering default probability. Government guarantees (through Dhamanat) absorb first-loss risk on a significant portion of the portfolio. Rising property values (Riyadh apartment prices up 82 percent since 2019) provide appreciating collateral. And the secondary market (through SRC) enables banks to transfer mortgage risk off their balance sheets.
However, SAMA must also consider tail risks. The residential sector index fell 2.24 percent during the year to Q4 2025, contrasting with the 5.12 percent year-on-year increase in Q1 2025 — suggesting that the period of rapid appreciation may be giving way to a more moderate or corrective phase. New residential mortgage loans declined 11 percent in 2025 to 108,795 contracts worth SAR 80.42 billion, down from the 17 percent and 18.9 percent growth rates seen in 2024. December 2025 origination of SAR 5.55 billion was down more than 53.5 percent from December 2024’s SAR 11.94 billion, and November 2025’s SAR 4.47 billion was the lowest monthly value of the year. These deceleration signals require SAMA to balance continued support for the housing programme against the possibility of overextension.
SRC Licensing and Secondary Market Development
SAMA’s licensing and oversight of SRC and approval of the Kingdom’s first RMBS transaction demonstrate its role in secondary market development — the creation of institutional infrastructure that enables mortgage risk to be distributed beyond the banking system.
SAMA’s no-objection approval for RMBS on August 21, 2025 opened a channel for mortgage market liquidity that did not previously exist. The first RMBS transaction — arranged by HSBC Saudi — featured senior, mezzanine, and junior tranches plus sukuk compatibility to attract both Islamic and institutional investors. S&P Global Ratings described the RMBS opportunity as “large,” anchored by USD 180 billion in home loans and a well-capitalised banking sector.
SAMA’s oversight of SRC extends to its sukuk programmes: the SAR 20 billion guaranteed local sukuk programme (including a final issuance of SAR 3.5 billion in dual tranches of 5 and 7 year durations) and the USD 5 billion international programme listed on the London Stock Exchange (first issuance of USD 2 billion completed in February 2025, oversubscribed 6 times by over 300 institutional investors in 3 and 10 year maturities). SAMA’s supervisory role ensures that SRC’s funding activities meet prudential standards and do not introduce systemic risk into the financial system.
SRC’s five-year target of SAR 75 billion in mortgage refinancing represents approximately 8 percent of the total mortgage market — a material but not systemically dominant share that SAMA views as sufficient to establish the secondary market without creating dependency on securitisation for primary lending.
Financial Consumer Protection
SAMA’s consumer protection mandate extends to mortgage borrowers through several channels. Disclosure requirements ensure that borrowers understand the total cost of financing, including profit rates, fees, insurance requirements, and early settlement charges. Complaint resolution mechanisms provide recourse when borrowers experience unfair treatment. And product regulation ensures that mortgage structures — whether murabaha, ijara, or other Islamic financing formats — meet minimum standards of fairness and transparency.
The five regulatory amendments approved by the Council of Ministers to the Housing Support Regulations — expanding the beneficiary pool, enhancing eligibility criteria, and increasing product distribution flexibility — reflect SAMA’s coordination with the Ministry of Municipalities and Housing on consumer-facing programme design. SAMA’s role in these reforms is ensuring that expanded eligibility does not compromise lending standards or financial stability.
Interaction with Housing Programme Institutions
SAMA’s housing role places it at the centre of an institutional web. It supervises the banks that originate subsidised and market-rate mortgages. It regulates SRC, which provides secondary market liquidity. It sets the LTV framework within which Dhamanat guarantees operate. Its rate decisions directly affect the fiscal cost of REDF subsidies (lower rates mean lower subsidy payments). And its financial stability mandate requires monitoring the collective impact of all these programmes on the banking system’s risk profile.
This central position gives SAMA unique influence — and unique responsibility. A miscalibrated LTV limit could either exclude families from homeownership (too restrictive) or generate a wave of defaults (too permissive). An inappropriate rate decision could either stifle housing demand or fuel an unsustainable price bubble. SAMA’s track record since 2017 — enabling a homeownership surge from 47 to 65.4 percent without triggering a financial stability crisis — suggests that the calibration has been broadly effective, though the deceleration in mortgage origination during late 2025 warrants continued vigilance.
Outlook: Navigating the Final Stretch to 70 Percent
The remaining 4.6 percentage points to the 2030 homeownership target of 70 percent will test SAMA’s ability to maintain the balance between accessibility and stability. The families yet to achieve homeownership are disproportionately lower-income and higher-risk, meaning the incremental mortgage portfolio will carry higher credit risk than the average of the existing book. SAMA may need to consider further LTV or DTI adjustments, enhanced guarantee frameworks, or expanded secondary market capacity to serve this population without compromising financial stability.
The interest rate outlook provides cautious optimism. With the repo rate at 4.25 percent and rates unchanged since December 2025, any future Fed cuts would create space for further SAMA reductions that directly improve mortgage affordability. Jadwa Investment’s expectation of gradually improving mortgage demand in 2026 aligns with the rate environment.
SAMA’s ultimate test will be whether the SAR 951 billion mortgage market can grow to SAR 1.3 trillion by 2030 — adding SAR 350 billion in real estate lending — while maintaining the credit quality, capital adequacy, and risk management standards that protect the Kingdom’s financial system. The central bank’s decisions over the next four years will determine whether Saudi Arabia’s housing transformation achieves its targets with financial stability intact.
