Saudi riyal’s real trade-weighted value falls about 6.5% from peak

Saudi Arabia’s real exchange rate has drifted lower since its January 2025 peak, easing the relative price of Saudi goods and services against those of its trading partners. The decline looks less like a sudden competitive breakthrough than a gradual improvement in the conditions facing businesses trying to sell abroad.

The real effective exchange rate, which combines exchange rates against trading partners with relative consumer prices, reached 98.6 in September 2026, down from a peak of 106. The path has been uneven, with pauses and rebounds, but the latest reading extends the broader downward movement. A lower reading points to improved price competitiveness; it does not directly measure exporters’ production costs or productivity.

The dollar peg remains unchanged at SAR 3.75. That fixes the riyal against the US currency, not against every currency used by Saudi customers and suppliers. When the dollar weakens against another currency, the riyal follows it. Saudi Arabia can therefore experience a trade-weighted depreciation without devaluing the peg or changing its exchange-rate framework.

The nominal effective exchange rate—the trade-weighted measure before adjusting for inflation—has fallen about 4.8% over the same period. This points to movements in the dollar against partner currencies as the main channel behind the broader weakening. The larger decline in the real measure also suggests that relatively subdued Saudi price growth has contributed. Domestic price pressures can persist, particularly in housing and services, while overall inflation still runs below that of trading partners.

For non-oil exporters, the benefit depends on what they sell and how they price it. Manufacturers with substantial local costs could offer more attractive foreign-currency prices or preserve prices and earn better margins in markets whose currencies have strengthened. Tourism and hospitality could also benefit: visitors from those markets would find Saudi accommodation, dining and entertainment cheaper in their own currency, provided local prices do not rise enough to cancel the advantage.

Petrochemical and plastics producers face a more qualified gain. Many products are priced in dollars and compete in global commodity markets, so a weaker trade-weighted riyal does not automatically translate into cheaper export offers. Demand, feedstock costs and overseas capacity may matter more. Exporters reliant on imported machinery, components or specialist services could also see part of the benefit absorbed by higher costs from suppliers using stronger currencies.

The same mechanism can squeeze households buying imported goods and businesses equipping new factories or hotels. The depreciation is therefore a modest tailwind for diversification, not a substitute for efficient production, reliable logistics or access to customers. What matters next is whether export volumes and margins improve—and whether higher import costs or domestic inflation erode the advantage. A dollar rebound could reverse the currency benefit even while the peg remains untouched.
