The Gilt-Edged Paradox: The Circular Absurdity of UK Monetary Financing

This "accounting insanity" is perhaps the most surreal feedback loop in financial macroeconomics. It creates a situation where the UK government is effectively borrowing money from the private market to pay for the losses the Bank of England (BoE) incurred while trying to influence that very same market.

To understand the absurdity, we have to look at the "Great Reversal" of the 2020s.

The "Iron Curtain" of Monetary Financing

Under the Bank of England Act 1998, there is a hard legal wall between the Treasury and the Bank. The BoE cannot simply print money and hand it to the Chancellor to pay for hospitals or schools. This is the "Monetary Financing" prohibition—a rule designed to ensure that the government doesn't use the central bank as a magic ATM, for fear it might lead to hyperinflation.

The Backdoor: The 2009 Indemnity

When the BoE started Quantitative Easing (QE) in 2009, they created a separate "bucket" called the Asset Purchase Facility (APF). To make this legal and protect the Bank’s balance sheet, the Treasury signed a Deed of Indemnity.

• The Deal: If QE made a profit, the Treasury kept it. If QE made a loss, the Treasury had to pay for it.

• The Golden Years: Between 2009 and 2022, it was a gold mine. The BoE sent £124 billion in profits to the Treasury. The government spent that money.

The Modern "Insanity": The Loop

Now that interest rates have risen to fight inflation, the "Gold Mine" has become a "Black Hole." The BoE is currently losing billions because the interest it pays to commercial banks (at the 3.75% Bank Rate) is much higher than the interest it earns on the old bonds it bought years ago.

Here is where the logic breaks down:

1. The Loss: The BoE reports a massivequarterly loss (e.g., £10 billion).

2. The Bill: Because of the indemnity, the Treasury is legally obligated to "fill the hole" with cash.

3. The Borrowing: The Treasury doesn't have £10 billion in spare cash. So, it instructs the Debt Management Office (DMO) to sell new gilts to the market.

4. The Irony: The Treasury is borrowing from the market (increasing national debt) to give cash to the BoE, so the BoE can pay interest to private banks.

The Paradox: The Bank of England is prohibited from lending to the Treasury to prevent "printing money," but the Treasury is forced to borrow from the market to fund the Bank's operational losses!

Why does this matter to the taxpayer?

This isn't just a "spreadsheet error" between two government buildings. It has real-world consequences:

• Fiscal Drag: Every billion the Treasury sends to the BoE is a billion that cannot be used for tax cuts or public spending.

• The Gilt Flood: By selling new gilts to cover these losses, the Treasury increases the total supply of debt in the market. As a consequence, the more gilts there are, the lower their price goes—and the higher the interest rate (yield) the government has to pay on all its debt.
