Introduction
Deflation, a sustained fall in the general price level, can have significant consequences, particularly for oil-exporting countries experiencing weak aggregate demand and sectoral imbalances. In 2019, oil-producing nations such as Saudi Arabia and the United Arab Emirates (UAE) faced deflation due to falling oil prices, which reduced government export revenues and impacted public spending. Additionally, an oversupply of property led to declining rental prices, exacerbating deflationary pressures. To address deflation, governments can either implement fiscal stimulus to boost aggregate demand or adopt policies that directly target the root causes, such as property-market imbalances and overreliance on oil exports. While fiscal stimulus can provide short-term relief, its sustainability is questionable given the already weakened fiscal positions of many oil-exporting countries, so long-term structural policies may be more effective.
Fiscal stimulus as a policy response
Fiscal stimulus refers to an increase in government expenditure aimed at boosting aggregate demand (AD) and stimulating growth. If an economy faces deflation from weak demand, higher government spending on infrastructure, subsidies or direct financial support can raise consumption and investment, shifting the AD curve rightward. In an economy near full employment, this rise in demand can raise the general price level, correcting deflation and restoring growth.
While effective in raising AD, oil-exporting countries may face significant constraints due to deteriorating budget positions. The decline in oil prices reduces government revenues from oil exports, a major share of national income, causing budget deficits that limit expansionary fiscal policy without borrowing or using reserves. If governments finance stimulus through borrowing, public debt rises, imposing a burden on future generations through interest payments and reducing long-term fiscal sustainability. Alternatively, governments could tap sovereign wealth funds or foreign-exchange reserves, but this carries opportunity costs, since these reserves generate investment returns for future spending, and depletion reduces fiscal flexibility in future downturns. If stimulus is applied near full employment, excessive spending could cause inflationary pressures rather than addressing deflation, and government borrowing may crowd out private investment by raising interest rates. Fiscal stimulus may therefore not be a sustainable long-term solution, particularly if deflation is structural rather than cyclical.
Addressing the oversupply of property
A key contributor to deflation in 2019 was the oversupply of property, which lowered rental prices and reduced revenues for property owners and developers. Since real estate is a significant sector in many Gulf economies, prolonged price declines can deepen deflation and reduce confidence. To correct oversupply, governments can raise demand for real estate. Through expansionary monetary policy, central banks can lower interest rates, making mortgages cheaper; lower borrowing costs encourage property purchases, boosting demand and stabilising prices, though effectiveness depends on banks' willingness to lend and consumer confidence. By relaxing foreign-investment and immigration rules, governments can ease restrictions on foreign ownership of real estate and offer residency incentives, expanding the market to international buyers and helping absorb excess supply. By directly addressing oversupply, these measures stabilise property prices and mitigate a key source of deflation without the fiscal constraints of expansionary spending.
Reducing dependence on oil exports
Another structural issue is overreliance on oil as a primary export, making these economies highly vulnerable to fluctuations in global oil prices. When oil prices fall, export revenues decline, weakening government spending and investment and causing job losses in oil-related industries. To diversify, governments can encourage the growth of non-oil sectors through tax incentives, subsidies or investment grants for manufacturing, tourism, financial services and technology, reducing reliance on oil revenues over time and making the economy more resilient. By investing in human capital and innovation through education, skills development and research and development (R&D), governments can equip the workforce for high-value industries beyond oil and gas; countries such as the UAE have promoted fintech, logistics and renewable energy to reduce reliance on oil exports. Diversification reduces the risk of future deflationary shocks linked to oil-price volatility.
Why lowering oil prices or depreciation is ineffective
Some may argue oil exporters should improve competitiveness by lowering oil prices further or depreciating the currency to make exports cheaper, but these are not viable. Oil prices were already declining in 2019, so further reductions would worsen fiscal conditions without necessarily increasing demand. Depreciation may not be effective because oil is typically traded in US dollars, so currency depreciation would not significantly affect oil-export competitiveness. Focusing on diversification and property-market stabilisation is a more viable long-term strategy.
Evaluative conclusion
While fiscal stimulus can increase aggregate demand and correct deflation in the short term, it is not a sustainable solution for oil-exporting countries due to worsening budget positions, rising debt and limited flexibility. Policies that directly address the underlying causes, the oversupply of property and overreliance on oil exports, are more effective in the long run. Measures such as lowering interest rates, attracting foreign investors and diversifying the economy can stabilise property prices, create alternative revenue streams and reduce vulnerability to oil-price fluctuations. Given the structural nature of the deflation, governments should prioritise economic transformation over short-term fiscal intervention to ensure long-term resilience and stability.
