Gilts Explained: What They Are, Why Everyone Is Talking About Them and What They Mean for Business

Gilts have become one of the most-discussed topics in UK financial news in 2026 — but for most business owners, they remain abstract. This FAQ explains what gilts are, why the current gilt market matters, and what it means for your business and your commercial property costs.

What is a gilt?

A gilt — or gilt-edged security — is a bond issued by the UK government. When the government needs to borrow money, it issues gilts: effectively, IOUs that it sells to investors. In return, it pays a fixed amount of interest (the coupon) each year and repays the face value when the bond matures.

The term "gilt-edged" dates from the 19th century, when the physical certificates had gold (gilt) edges — a mark of the highest quality and the lowest risk.

What is a gilt yield?

The yield is the annual return an investor earns from holding a gilt. It is expressed as a percentage of the current market price — not the original face value.

Here is the key relationship: when the price of a gilt falls, the yield rises. When the price rises, the yield falls. They move in opposite directions.

If investors are concerned about lending to the UK government — because of inflation risk, fiscal concerns, or political uncertainty — they demand a lower price to buy the gilt, which means a higher yield. A high yield signals that the market is pricing in more risk or requiring more compensation to hold UK government debt.

What is happening to UK gilt yields right now?

The UK 10-year gilt yield reached 5.39% in September 2026 — the highest level since 2007. A year ago, the same yield was around 4.2%. Two years ago, it was around 3.5%.

This is a significant move in a short time. It reflects a combination of factors: UK inflation remaining above target at 3.1%, a large government fiscal deficit requiring continued gilt issuance, uncertainty ahead of the Autumn Budget, and the UK's divergence from the global trend toward lower rates.

Why is the UK a G7 outlier on gilt yields?

Most major economies are cutting interest rates or have stabilised at lower levels than the UK. The US Federal Reserve has been cutting since late 2025; the European Central Bank has moved through two cuts this year. Japan and Canada are also easing.

The UK is an exception for several reasons:

• Inflation is stickier. CPI at 3.1% is above the Bank of England's 2% target, driven by services inflation and wage growth that has not yet fully moderated.
• The fiscal position is larger. The UK is running a significant deficit and issuing more gilts than most comparable economies. More supply of gilts pushes prices down and yields up.
• Sterling weakness in 2025 raised the cost of imports and energy, keeping inflation elevated.
• Political uncertainty around the Autumn Budget adds a premium that investors demand for holding UK debt.

Why does anyone care about gilt yields? They seem very distant from everyday business.

They are much closer than they appear. Gilt yields are the benchmark off which most financial products in the UK are priced — mortgages, corporate loans, commercial property debt, and pension fund returns.

When gilt yields rise, the cost of borrowing across the economy rises with them. This is not immediate — existing loans at fixed rates are unaffected until they mature — but over time, higher gilt yields filter through to every business and household that borrows.

What do gilt yields mean for commercial property specifically?

Commercial property is almost always financed with debt. That debt is priced at a margin above the gilt rate — typically gilt plus 150 to 250 basis points (1.5% to 2.5%). When gilts yield 5.39%, a commercial property loan might be priced at 7% to 8%.

This has two effects:

For landlords: Refinancing existing loans at current rates has dramatically increased annual interest costs. A landlord who borrowed at 2.5% in 2019 is now refinancing at 7.5% or more — a tripling of interest cost on the same loan. This puts pressure on their income and motivation to fill vacant space.

For property values: Investors compare the income return from property to the risk-free return from gilts. When gilts yield 5.39%, property needs to yield materially more to attract investors. Where rents are not rising fast enough to justify current prices at these yields, capital values fall. Commercial property capital growth was just 0.1% in H1 2026 — effectively zero in real terms.

What does this mean for my business?

If you rent commercial space, the gilt market affects you in two ways:

Your landlord's motivation. A landlord with refinancing pressure — paying much more in interest than they expected — has more reason to keep space let, to be flexible on terms, and to negotiate with a reliable occupier. This improves your position.

The cost of your own borrowing. If your business uses a loan secured on property — a commercial mortgage, an asset finance facility — the rate you pay is linked to the same benchmark. As gilt yields stay high, borrowing costs for businesses remain elevated.

Will gilt yields come down?

Markets expect gilt yields to remain elevated through 2026 and into 2027. A significant fall in yields would require one or more of: UK inflation returning sustainably to target, a credible fiscal consolidation plan reducing the deficit, or a meaningful economic slowdown reducing demand for new government borrowing.

None of these is imminent. The most likely scenario is that yields remain in the 4.5%–5.5% range for the foreseeable future, with direction heavily influenced by the Autumn Budget and Bank of England decisions.

What should my business do in response?

• If you are looking for commercial space: Use the current environment. Landlord motivation is high; negotiating terms — rent-free periods, break clauses, stepped rents — is easier than it has been in years.
• If you are renewing a lease: Start negotiations early and do not simply accept the first terms offered. A landlord facing refinancing pressure is more flexible than their initial position suggests.
• If you have a commercial mortgage: Review the rate environment and your refinancing timeline. Fixed rates lock in current costs; variable rates expose you to further movement.
• If you are considering a long-term property commitment: Model the cost over multiple scenarios. Signing a ten-year lease now is a decision made in a high-rate environment that may look different in five years.
