Fiscal impact of the war in Iran 2026 on mortgage rates: Understanding the issues for real estate buyers and homeowners

01 Apr 2026

The war in Iran, which began in February 2026, has significant repercussions on the global economy, particularly in Europe and the United States. These geopolitical tensions influence financial markets, inflation, central bank policies, and, consequently, mortgage rates. This article explores these impacts and offers perspectives for 2026, along with practical advice for homebuyers and homeowners.

Impact on financial markets and inflation

The conflict in Iran has led to a notable rise in energy prices, especially oil, due to supply disruptions, including the blockade of the Strait of Hormuz, through which about 20% of the world's oil passes. This situation has revived inflationary fears on a global scale. The European Central Bank (ECB) has thus revised its inflation forecasts for 2026 upward, now estimating an average inflation of 2.6%, compared to 2.0% previously. In a more adverse scenario, inflation could reach 3.5%, or even 4.4%, depending on the duration of energy supply disruptions. Christine Lagarde, President of the ECB, stressed that the war in Iran has a "material impact" on inflation in the short term.

Repercussions on central bank policies

Faced with these inflationary pressures, central banks are adjusting their monetary policies. In the United States, the Federal Reserve (Fed) signaled a pause in planned rate cuts due to uncertainties related to the Iran conflict and the resurgence of inflation pressures.

Consequences for mortgage rates

Fluctuations in financial markets and the adjustments in monetary policy directly influence mortgage rates. In the United States, the average rate for 30-year fixed-rate mortgages rose to 6.38%, its highest in six months, due to uncertainties related to the Iran conflict.

Outlook for 2026

Economic projections for 2026 vary depending on the evolution of the conflict in Iran. The Organisation for Economic Co-operation and Development (OECD) has adjusted its Spain forecast, estimating inflation at 3% in 2026, up from 2.3% previously, due to the global impact of the war in Iran. ([elpais.com](https://elpais.com/economia/2026-03-26/la-ocde-calcula-que-la-inflacion-subira-al-3-en-2026-por-la-guerra-en-iran.html?utm_source=openai)) If the conflict persists, further monetary adjustments could be considered to curb inflation, which would have implications for interest rates and, by extension, mortgage rates.

Practical advice for homebuyers and homeowners

Monitor market trends: Stay informed about economic and geopolitical developments, as they can influence interest rates and financing conditions.
Consider loan duration: If you are planning a long-term loan, a fixed rate could offer stability in the face of potential interest rate fluctuations.
Assess your borrowing capacity: Ensure your finances are solid to cope with potential rate increases or inflation-related costs.
Consult experts: Seek advice from financial advisors or mortgage brokers to obtain guidance tailored to your personal situation.
