Overview

The financial markets have reacted negatively to the recent political changes in the UK, particularly following the appointment of Andy Burnham as Prime Minister and the dismissal of Rachel Reeves as Chancellor. This shift has led to a significant rise in UK bond yields, indicating increased investor concern regarding the new government's fiscal policies.

Market Response

On the day of Burnham's appointment, the 2-year bond yield increased by 8 basis points, while the 10-year yield surpassed 5%, marking a notable rise. The uncertainty surrounding the new Chancellor's identity and the potential economic policies has contributed to this volatility. Investors are particularly anxious about the possibility of Ed Miliband being appointed as Chancellor, a choice that could exacerbate market fears.

Burnham's Spending Plans

In his first day in office, Burnham proposed a substantial £24 billion increase in government spending. This includes:

• £2 billion to manage Thames Water's administration until 2027.
• £18 billion to provide social care services free at the point of use, similar to NHS services.
• £4 billion to increase the tax-free allowance.

Additionally, further cost-of-living measures are expected to be announced, which could add to the financial burden.

Concerns Over Economic Policy

Despite Burnham's assurances that new spending will be fully funded, investor skepticism remains high. Analysts have raised concerns about the effectiveness of extending the tax-free allowance, suggesting it may not significantly stimulate consumption. Furthermore, the Institute of Fiscal Studies highlights that a small percentage of taxpayers contribute a large portion of tax revenue, raising questions about the sustainability of high tax rates.

Political Risk and Currency Impact

The political risk premium in the UK has increased, reflected in the performance of the British pound, which has weakened against major currencies. The GBP/USD pair has retreated from the $1.35 mark, indicating a loss of confidence among investors.

Conclusion

The initial market response to Burnham's premiership suggests a lack of confidence in his economic strategy, particularly regarding spending and taxation. As the situation develops, investors will be closely monitoring the new Chancellor's appointment and the clarity of Burnham's economic policies to gauge their potential impact on the UK economy.
