In recent months, rising geopolitical tensions, particularly involving the US–Iran conflict have started to influence global financial markets. For homeowners and buyers of HDB and Private Property in Singapore, the key question is straightforward: Will this impact mortgage interest rates?

The answer is not direct, but the effects are already being felt.

This article breaks down what is happening in 2026, why rates are moving, and what borrowers should expect going forward.

Current Situation: Rates Are Already Moving Up

As of 2026, we are beginning to see early upward pressure on fixed home loan rates in Singapore.

Local banks have adjusted their packages, with the lowest fixed rates increasing from around 1.45% to approximately 1.60%. While this may seem like a small movement, it signals a shift in market sentiment.

Foreign banks are also reacting, but in a more segmented manner. For smaller loan amounts, fixed rates have increased, while for larger loan sizes, some banks are still offering 2-year fixed packages at around 1.45%. However, these are becoming more selective and less widely available.

More notably, 3-year fixed rate packages are becoming less attractive or disappearing altogether. Where available, they are now priced closer to 1.80% or higher, reflecting increased uncertainty over the medium-term interest rate outlook.

This behaviour suggests that banks are becoming more cautious, especially when committing to longer-term fixed rates.

Why Is This Happening? The Role of Oil and Inflation

At first glance, it may seem unclear how tensions between the United States and Iran could influence mortgage rates in Singapore. The connection, however, lies in the broader global financial system.

The Middle East plays a crucial role in global oil supply. Any instability in the region, particularly involving Iran, raises concerns about disruptions to oil production and transportation, especially through strategic routes such as the Strait of Hormuz.

When such risks emerge, oil prices tend to rise. This increase in energy costs has a cascading effect across the global economy. Transportation becomes more expensive, production costs increase, and businesses pass on these costs to consumers. The result is inflationary pressure.

Inflation is one of the primary factors influencing interest rate decisions. When inflation remains elevated, central banks are less inclined to lower interest rates, as doing so could further fuel price increases.

This is where the connection becomes clear. Even though Singapore does not set its mortgage rates independently, it is highly influenced by global interest rate trends, particularly those of the United States.

The Link to Singapore Mortgage Rates

Singapore home loan rates are largely influenced by benchmarks such as SORA (Singapore Overnight Rate Average), which in turn are affected by global liquidity conditions.

Because the Singapore dollar is closely managed against a basket of currencies and the financial system is highly open, interest rate trends in the US tend to flow through to Singapore.

As a result:

• When US rates stay high → Singapore rates remain elevated
• When US signals uncertainty → banks price in risk (higher fixed rates)

This explains why even without direct domestic changes, Singapore mortgage rates are already adjusting in response to global developments.

Why Fixed Rates Are Rising Faster Than Floating Rates

One interesting observation in 2026 is the divergence between fixed and floating rates.

Currently, floating rate packages remain relatively attractive, with all-in rates around 1.00% for the first year (commonly structured as 1M or 3M SORA + 0% spread for Year 1).

This creates a situation where:

• Floating rates are still low (short-term view)
• Fixed rates are rising (forward-looking risk pricing)

Banks are effectively pricing in uncertainty. Fixed rates reflect expectations of future interest rates, not current conditions. With inflation risks and geopolitical tensions in play, banks are reluctant to lock in low rates for longer durations.

This is why:

• 2-year fixed rates are still available (shorter commitment)
• 3-year fixed rates are expensive or limited

What About the US Federal Reserve?

The policies of the Federal Reserve play a central role in shaping global interest rates.

In 2026, the Federal Reserve has chosen not to cut interest rates, primarily due to ongoing concerns about inflation. The rise in oil prices linked to geopolitical tensions only reinforces this cautious stance.

For Singapore, this has direct implications. Because the Singapore dollar is managed within a trade-weighted exchange rate system and the financial system is highly open, interest rate movements in the US tend to flow through to Singapore.

When the Federal Reserve maintains higher rates:

• Global borrowing costs remain elevated
• Liquidity tightens
• Banks in Singapore adjust their pricing accordingly

This is why, even without domestic policy changes, we are seeing upward adjustments in fixed mortgage rates locally.

Inflation: The Core Driver Behind Rate Movements

At the heart of this entire situation is inflation.

Rising oil prices, driven by geopolitical instability, contribute directly to higher global inflation. This creates a challenging environment for central banks, which must balance economic growth with price stability.

When inflation remains high:

• Interest rate cuts are delayed
• Borrowing costs remain elevated
• Financial markets become more cautious

For borrowers, this translates into a more complex decision-making environment. While current rates may still appear attractive, future movements are less predictable.

What Can Borrowers Expect Moving Forward?

Looking ahead, the trajectory of mortgage rates will depend on several factors, including geopolitical developments, inflation trends, and central bank policies.

If tensions in the Middle East persist or escalate, oil prices may remain elevated, sustaining inflationary pressure. This would likely keep interest rates higher for longer and may even lead to further increases in fixed rate packages.

Conversely, if geopolitical risks ease and inflation stabilises, there may be room for central banks to consider rate cuts. Current market expectations suggest that meaningful rate reductions may only occur in 2027, assuming inflation is brought under control.

In the meantime, borrowers should expect:

• Continued volatility in fixed rate offerings
• Limited availability of longer-term fixed packages
• Greater variation between banks based on risk appetite

Strategic Considerations for Borrowers in 2026

In this environment, choosing the right home loan package is no longer straightforward.

Borrowers need to move beyond simply comparing headline rates and instead consider their risk tolerance and financial stability.

Fixed rate packages offer certainty. They protect borrowers from potential rate increases but come at a higher cost upfront. This may be suitable for individuals who prioritise stability and want to avoid future volatility.

Floating rate packages, on the other hand, offer lower initial rates but expose borrowers to future fluctuations. These may be more suitable for those who are comfortable with some level of risk and are prepared to monitor market conditions.

Importantly, there is no universally “correct” choice. The right decision depends on individual circumstances, including income stability, financial commitments, and long-term plans.

The Bigger Picture: Beyond Just Interest Rates

While much of the focus is on interest rates, it is important to recognise that mortgage decisions should be part of a broader financial strategy.

Factors such as property plans, cash flow management, and long-term investment goals all play a role in determining the most suitable loan structure.

Geopolitical events like the US–Iran conflict serve as a reminder that external factors can influence financial conditions in unexpected ways. As such, borrowers should adopt a flexible and informed approach rather than relying solely on current market conditions.

Final Thoughts

The US–Iran conflict is not a direct determinant of Singapore home loan interest rates. However, its impact on oil prices and inflation creates ripple effects that influence global monetary policy, eventually affecting local mortgage rates.

In 2026, these effects are already visible. Fixed rates are rising, longer-term packages are becoming less attractive, and uncertainty is shaping how banks price their loans.

For borrowers who are looking to purchase their HDB, Condo or New launch, the key takeaway is clear: interest rate decisions must account for both current conditions and future risks.

Why Professional Advisory Matters

In a rapidly changing interest rate environment, navigating mortgage options requires more than just comparing rates.

Different banks respond differently to market conditions. Some may still offer competitive packages under specific criteria, while others may adopt a more conservative approach.

As Singapore’s largest mortgage advisory, Fairloan works closely with clients to analyse market trends, compare options across all banks, and structure loans based on individual risk profiles.

Whether you are purchasing a new property or refinancing an existing loan, having the right guidance can make a significant difference, not just in securing approval, but in optimising your long-term financial position.
