How markets reacted to uncertainty over Rachel Reeves's future

UK financial markets experienced volatility on Wednesday, with sterling depreciating to a week-long low of $1.35 and €1.15, while 10-year gilt yields rose to 4.67% and 30-year yields to 5.45%. This reaction stemmed from investor concern over the government's commitment to fiscal rules and debt reduction, triggered by uncertainty surrounding Chancellor Rachel Reeves's tenure following a welfare bill U-turn. Markets partially recovered after the Prime Minister's office affirmed full support for Reeves, aiming to quell speculation regarding her future.

Analysis

UK financial markets priced in a higher political risk premium following uncertainty over the tenure of Chancellor Rachel Reeves. This concern, stemming from a government U-turn on a key welfare bill, triggered a notable sell-off in sterling and a rise in government borrowing costs. Specifically, the pound fell to a week-long low of $1.35 and hit €1.15, a level not seen since mid-April. Concurrently, UK gilt yields increased, with the 10-year yield reaching 4.67% and the 30-year yield hitting 5.45%, marking highs for June and May respectively. This market reaction indicates investor anxiety that a change in Treasury leadership could jeopardize the government's commitment to its self-imposed fiscal rules for debt reduction and budget balancing. While a subsequent statement of support for the Chancellor from the Prime Minister's office led to a partial recovery, the episode highlights the market's acute sensitivity to perceived fiscal instability and the government's ability to adhere to its spending plans.

Key Decisions for Investors

• Investors should closely monitor political communications regarding the UK's fiscal strategy, as the market has demonstrated high sensitivity to any perceived deviation from stated debt and budget rules.
• Given the heightened volatility in sterling and gilts, it may be prudent to review and potentially hedge UK-specific currency and duration risk until there is greater clarity on the government's fiscal path.
• Pay close attention to any forthcoming announcements on how the government intends to fund the shortfall from its welfare bill U-turn, as this will be a critical catalyst for UK asset prices.
