What's causing the UK's long-term borrowing costs to rise?

The UK's long-term borrowing costs have been on the rise, posing a challenge for the government's fiscal policies. This increase in the cost of government borrowing is driven by several factors, including global economic conditions, market uncertainties, and the Bank of England's monetary policy decisions. The rise in borrowing costs could have significant implications for the public finances, as it means the government will have to allocate more resources to servicing its debt. This, in turn, could limit the government's ability to invest in public services, infrastructure, and other important areas. The upcoming Budget will be a crucial test for the government, as it will need to balance the need for fiscal discipline with the need to support the economy and address the rising cost of living. The government will need to carefully consider the impact of its policies on the public finances and ensure that it is able to borrow at a sustainable cost.
