Knight Frank’s analysis of the aftermath of the October 30 Budget offers a sobering view of its impact on the UK financial and housing markets. It highlights growing instability in the mortgage and property sectors, while also pointing to unintended consequences of fiscal policies aimed at foreign investors and high-value property transactions.

Key Takeaways:

1. Rising Mortgage Rates and Bond Yields:

• Government bond yields have risen significantly, with the five-year yield climbing from below 3.9% in early October to above 4.4% by mid-November.
• This rise in yields reflects decreased investor confidence in UK creditworthiness and is pushing up mortgage rates.
• Market expectations for the Bank of England base rate have also shifted higher, with projections for December 2025 now in the 4%–4.25% range, compared to 3.5% two months ago.

2. Impact on the Housing Market:

• Knight Frank anticipates downward pressure on house prices and transaction volumes as higher rates erode affordability.
• While activity levels had been strong following rate declines in late summer, the upward trend in mortgage costs is expected to reverse this momentum.
• Prime residential markets, often insulated by cash buyers, are not immune to these challenges, with increased uncertainty stemming from speculation around wealth taxation.

3. Missed High-Value Transactions and Stamp Duty Revenue:

• Speculation over abolishing the non-domiciled tax regime has dampened foreign investor interest, leading to a noticeable drop in high-value property transactions.
• Since March 2023, the UK has reportedly missed 107 transactions in the £5 million–£10 million range and 35 deals above £10 million.
• This slowdown equates to a theoretical loss of over £140 million in stamp duty revenue, exacerbating fiscal pressures.
• This shortfall is significant in the context of total stamp duty revenue for 2023/24, which stood at £11.6 billion.

4. Economic and Fiscal Risks:

• The combined effect of rising borrowing costs, reduced property transactions, and speculative tax policy has created further strain on government finances.
• The estimated £22 billion fiscal gap could widen if policies continue to deter high-net-worth individuals and foreign investors, who contribute significantly to stamp duty and other tax revenues.

Commentary from Knight Frank:

• Tom Bill, head of residential research, underscores the risks of rising mortgage rates and their delayed impact on the housing market, noting that “it will take a few more months before the full impact is felt.”
• He also points to the importance of monitoring foreign investor activity and bond market reactions, as these are critical to maintaining fiscal stability and housing market resilience.

Implications:

The government faces a delicate balancing act:

1. Support for Mortgage Borrowers: Rising costs could pressure policymakers to introduce measures to ease affordability concerns, though this may conflict with inflation-control efforts.
2. Taxation of Wealth: Clear and stable tax policies are essential to retain foreign investor confidence and prevent further loss of high-value property transactions.
3. Housing Market Health: As higher rates impact affordability, the government and lenders may need to explore innovative financing solutions or targeted support for buyers to maintain activity levels.

This analysis highlights the complex interplay between fiscal policy, financial markets, and housing dynamics. It also serves as a reminder of the cascading effects that misjudged signals or speculation can have on investor behavior and government revenues.
