Why UK’s 2025 budget has Rachel Reeves facing an trilemma.

A Tough Job for the Chancellor

Rachel Reeves is the UK’s Chancellor of the Exchequer. She is the finance minister (Rachel Reeves). Her job is to manage the country’s money. This is a very difficult job right now.

In the 2025 Budget, she is facing a huge problem. Leading experts call this problem the “impossible trilemma.” A trilemma is a choice between three things. You cannot have all three at the same time. You must choose two and give up one.

This trilemma is what makes her job so hard. She wants to do three things for the country. She must choose only two.

1. She wants to protect public services. This means spending money on hospitals and schools.
2. She wants to avoid big tax rises. This means keeping promises to working people.
3. She wants to follow the strict fiscal rules. This means controlling the national debt.

Experts say it is impossible to do all three at once. Something must break. She must either raise taxes, cut spending, or break her promise on debt rules. Rachel Reeves

The Big Problem: A Hole in the Finances Rachel Reeves

Why is this problem so large? It is because the UK has a major fiscal hole in its budget. This is like a big gap between the money coming in and the money going out.

Economists say this hole could be huge. Some say it is around $\text{£}41$ billion (or $54$ billion dollars). This is a lot of money. The government needs to find this money just to meet its current plans.

This money gap comes from a few main problems:

• Weak Economic Growth: The UK economy is growing very slowly. Slow growth means less money comes in from taxes. The official forecasts for future growth are also weak.
• High Debt Costs: The UK’s national debt is very high. Interest rates have gone up. This means the government must pay a lot more money just to pay the interest on the debt. This money cannot be spent on schools.
• Policy U-turns: The government had to change some plans. They changed plans to cut payments to retired people. They also changed plans to cut help for people who are sick for a long time. These changes cost billions of pounds.

Because of these problems, the Chancellor has very little room to make new choices.

The Three Impossible Choices (The Trilemma) Rachel Reeves

Rachel Reeves has three goals. She wants to keep her promises on all three. But the money simply does not add up.

Choice 1: Protect Public Services (High Spending)

The first choice is to keep spending money on important services. The UK’s public services are under great pressure.

• NHS: The National Health Service (NHS) needs billions of pounds more every year. Waiting lists for treatment are very long.
• Schools: Schools need money for teacher pay and building repairs. Rachel Reeves
• Police: More money is needed for police forces and the justice system.

The public is very unhappy with the current state of these services. The government wants to fix them. But fixing them means spending more money. If she spends this money, she must find it somewhere else. This clashes with the other two choices. Rachel Reeves

Choice 2: Avoid Big Tax Rises (Low Taxes)

The second choice is to keep a promise. The Labour Party promised not to raise taxes on “working people.” This is a huge promise. It limits what the Chancellor can do. Rachel Reeves

The promise says she will not raise these big taxes:

• Income Tax rates (the main tax on salaries).
• National Insurance (a tax on earnings).
• VAT (Value Added Tax, a tax on things you buy).

These three taxes bring in about $75\%$ of all the government’s money. If she cannot touch them, her options are very limited. She cannot raise the main taxes easily. This makes it hard to find the money needed for Choice 1 (Public Services).

Choice 3: Follow Strict Fiscal Rules (Control Debt) Rachel Reeves

The third choice is to keep financial stability. Rachel Reeves has set strong fiscal rules. These are rules about how much the government can borrow. Rachel Reeves

The main rule is this: The government must be able to cover its day-to-day spending with tax money. It must not borrow money for daily costs. This rule must be met by the end of the next few years.

Following this rule is important. It makes investors trust the UK government. If investors trust the government, they lend money cheaply. Breaking this rule could make the UK look risky. Borrowing costs would go up.

To follow this rule, the government must find the $\text{£}41$ billion hole. This forces her to choose between Choices 1 (Spending) and 2 (Taxes).

How Reeves is Trying to Fix the Trilemma

Rachel Reeves is trying to find money without breaking her main promises. She is looking for ways to raise money quietly. This is called a “smorgasbord” of smaller tax changes.

Here are some ways she is trying to solve the problem:

• The “Stealth Tax” of Frozen Thresholds: She can freeze tax thresholds for a longer time. The threshold is the level of salary where you start paying tax. If this level stays the same, and your salary goes up, you pay more tax. This pulls more people into paying tax. It raises money without “raising the rate” of tax. It is a quiet way to get more money. This could raise about $\text{£}10.4$ billion.
• Targeting the Wealthy: She can raise taxes on rich people. This includes increasing taxes on people’s wealth when they sell assets, called Capital Gains Tax. She may also look at a surcharge on the most expensive houses. Some people call this a “mansion tax.”
• Pension Reform: There are rumors she could reduce tax breaks on some pension savings. This would affect higher earners.
• Closing Loopholes: She can try to stop rich people and large companies from avoiding tax legally. This is about making sure everyone pays what they owe.

The Chancellor hopes that many small tax rises will add up to enough money. She is trying to protect the public services and keep her promise on the main tax rates. But she still needs to find tens of billions of pounds.

What is the Risk if She Fails? Rachel Reeves

If Rachel Reeves cannot find the money, she must break one of her promises. Each choice has a great risk:

1. Break the Spending Promise (Cut Public Services): She would have to cut money for hospitals, schools, and police. This would make the public very angry. It would make services worse. This would be a political disaster for the new government.
2. Break the Tax Promise (Raise Income Tax): She would have to raise Income Tax or National Insurance. This would be a broken promise to “working people.” It would be very unpopular. It would hurt the low- and middle-income families she promised to protect.
3. Break the Debt Rule (Change Fiscal Rules): She could change her own fiscal rules to allow more borrowing. This would make the government look weak on money management. Investors would worry. This could raise the cost of national debt. It would also hurt the reputation of the new government.

The impossible trilemma is a trap. It means the Chancellor has no easy way out of the financial hole. She must choose the path that causes the least political damage while keeping the country’s finances stable. Her ability to solve this problem will define her time as Chancellor.
