How the SAR Peg and Interest Rates Affect Saudi Property Returns

A worked, illustrative example showing how a rise in financing rates, which in Saudi Arabia tend to track US policy, changes the return on a leveraged property investment.

Because the Saudi riyal is pegged to the US dollar, SAMA has historically moved its policy rates in step with the US Federal Reserve, so financing costs for Saudi property often rise and fall with US monetary policy rather than with local conditions. For a leveraged investor, that link can matter more than the local market itself. The example below shows how a rate change passes through to cash return.

The situation

An investor plans to buy an income-producing property in Riyadh using bank financing priced at a margin over a floating benchmark such as SAIBOR. They want to understand how their cash return changes if the benchmark rises after purchase. All figures are illustrative and do not describe current rates or prices.

Assumptions (illustrative)

• Property cost including acquisition costs: SAR 5,000,000 (illustrative).
• Financing: 60 per cent of cost, equal to SAR 3,000,000, interest-only for simplicity.
• Equity invested: SAR 2,000,000.
• Assumed net operating income: SAR 350,000 per year.
• Assumed initial all-in financing rate: 6 per cent.
• Assumed rate rise scenario: all-in rate increases to 8 per cent.

Step 1: Unleveraged yield

SAR 350,000 divided by SAR 5,000,000 equals 7 per cent.

This is what the property earns before financing, and it does not change when rates move.

Step 2: Interest cost at the starting rate

SAR 3,000,000 multiplied by 6 per cent equals SAR 180,000 per year.

Because the property yields more than the financing costs, borrowing adds to the equity return.

Step 3: Cash return on equity at the starting rate

SAR 350,000 minus SAR 180,000 equals SAR 170,000; SAR 170,000 divided by SAR 2,000,000 equals 8.5 per cent.

Leverage lifts the return from 7 per cent to 8.5 per cent while the rate stays below the property yield.

Step 4: Interest cost after the rate rise

SAR 3,000,000 multiplied by 8 per cent equals SAR 240,000 per year.

The same debt now costs SAR 60,000 more each year, with no change in the property itself.

Step 5: Cash return on equity after the rise

SAR 350,000 minus SAR 240,000 equals SAR 110,000; SAR 110,000 divided by SAR 2,000,000 equals 5.5 per cent.

The return falls below the unleveraged 7 per cent: borrowing now reduces the equity return instead of increasing it.

Step 6: Find the break-even rate

Leverage stops helping when the financing rate equals the property yield of 7 per cent; at 7 per cent, interest is SAR 210,000 and cash return is SAR 140,000 divided by SAR 2,000,000, equal to 7 per cent.

Any financing rate above 7 per cent in this example makes the investor worse off than buying without debt.

What changes the answer

• Higher rates often also push valuations down, because buyers demand higher yields, so capital value can fall at the same time as cash return.
• A fixed-rate or hedged facility changes the result, at the cost of pricing and early-repayment terms to be agreed with the bank.
• Amortising debt increases annual cash outflow beyond the interest shown here.
• Rents may rise with inflation, partly offsetting higher rates, but Riyadh rent restraint measures introduced in 2025 can limit that for residential leases.
• A lower loan-to-cost ratio reduces both the upside and the damage from a rate rise.

What the numbers tell you

• Watch US monetary policy as closely as the local market when you borrow in riyals.
• Calculate the rate at which leverage stops helping before you sign the facility.
• Stress the equity return at a financing rate at least two percentage points above today.
• Remember that rate rises can hit both income and value at the same time.
• Discuss fixing or hedging with your bank before drawing the loan, not after rates move.
