Kwarteng’s Mini-Budget: Experiencing a Live Liquidity Crunch

Immediate Market Turmoil

The announcement of £45 billion in tax reductions without clear funding sent shockwaves through financial markets. Gilt yields soared and the pound plummeted, prompting the Bank of England to step in with emergency bond purchases to restore stability. This intervention highlighted the severity of the disruption.

Households felt the impact quickly. Mortgage rates, which were already on the rise, surged even higher. On 20 October 2022, the average five-year fixed mortgage rate hit 6.51%, dramatically increasing monthly payments for millions. This jump was directly linked to the spike in government borrowing costs.

The international response was swift. Senior officials in Washington questioned how Britain had managed to alter a major global financial benchmark—the Fed Fund futures curve—on its own. This moment of vulnerability forced the chancellor to reassure US bankers that the UK remained committed to responsible fiscal management.

The Fiscal Reality Check

The anticipated economic boost failed to appear. Liz Truss argued her plan would save £35 billion and drive growth, but the markets disagreed. Instead, investors demanded an additional £72 billion to cover the unfunded tax cuts, forcing a rapid reversal of policy.

This was not just a policy debate—it was a liquidity crisis, as private investors refused to fund the government's ambitions.

Economic projections reveal the underlying weakness. The UK's expected GDP growth for 2025 is only 0.25%, a fraction of the pre-2008 average, confirming the ongoing "managed decline" Truss sought to end. The mini-budget failed to ignite growth, leaving the economy facing persistent inflation and looming recession risks.

Most of the original policy agenda has now been reversed by Sunak and Hunt, but the damage to the UK's fiscal reputation remains. With inflation still high and borrowing costs elevated, the government is trapped between stagnant growth and the threat of further monetary tightening. While the growth plan has been abandoned, its fiscal and economic consequences continue to affect the country.

Current Liquidity and Fiscal Strategy

The government currently maintains a protective buffer of £22 billion, described as a safeguard against aggressive bond market reactions. This reserve was built to prevent another crisis like the one in 2022, offering a measure of security against sudden fiscal shocks.

However, the term "mini-budget" now carries negative connotations. The September 2022 fiasco has made any future growth-oriented fiscal proposals politically risky. The market's strong response—forcing policy reversals and central bank intervention—has set a precedent where ambitious economic plans are met with skepticism and higher borrowing costs.

The latest Budget reflects this cautious approach. It avoids bold growth strategies, focusing instead on preventing another crisis. The chancellor's goals are modest, shaped by the need to avoid repeating past mistakes. Without a clear vision for long-term growth, the government is focused on managing current challenges rather than planning for future prosperity.
