The United Kingdom is poised to increase defence spending under the new government led by Prime Minister Andy Burnham, signaling potential growth for the nation’s defence sector. This development follows recent cabinet appointments and statements indicating a shift toward higher investment in military capabilities.

John Healey, appointed Chancellor and former defence secretary, is expected to prioritize defence funding, having previously resigned over budget concerns. Analysts note that Healey has advocated for raising defence expenditure to 3% of GDP by 2030, surpassing the previous target of 2.68% set during the Sir Keir Starmer administration, with the eventual goal of meeting NATO’s 3.5% guideline by 2035. Despite competing fiscal demands, experts suggest it will be difficult for the Treasury to leave defence spending unchanged.

Wes Streeting, the current Defence Secretary, has expressed readiness to support this funding increase, describing his relationship with the Treasury as that of a “firm friend,” which market commentators interpreted as a signal of impending policy shifts. Streeting has also emphasized that defence will not be “done on the cheap,” reinforcing expectations of an upward trajectory in defence budgets over the next decade.

The renewed focus on defence has translated into positive market reactions for British defence companies. Shares of industry leaders such as BAE Systems, Babcock, Rolls-Royce, Chemring, QinetiQ, and AIM-listed Cohort have all seen gains. For example, Cohort’s shares have surged nearly 42% year-to-date, reflecting investor enthusiasm amid the anticipated spending increases. These firms produce various critical capabilities, including aerospace technology, naval vessels, advanced sonar systems, and cyber defence solutions.

Speculation has also grown around the potential issuance of “war bonds” by Chancellor Healey to generate additional funding beyond the £15 billion outlined in the current Defence Investment Plan (DIP). Both Burnham and his predecessor, Sir Keir Starmer, have acknowledged that the country’s defence resources have been insufficient given current security challenges, including ongoing global conflicts.

UK defence analysts highlight that increased military expenditure is part of a broader international trend, where national security and military readiness are seen as essential to societal stability. Joakim Agerback, fund manager of the Finserve Global Defence & Security Fund, noted that similar defence spending strategies are emerging worldwide in response to evolving threats.

While the UK defence sector shows promise, some European defence companies have faced challenges. German group Rheinmetall’s shares have dropped amid concerns about traditional artillery’s relevance compared with newer technologies such as drones and precision-guided munitions. However, Rheinmetall remains rated as a potential buy due to its diversified capabilities. In the United States, companies like RTX (formerly Raytheon) are experiencing increased demand for missile systems depleted by recent conflicts, while aerospace giants Boeing and Northrop Grumman dominate the drone market.

US shipbuilder Huntington Ingalls is also expected to benefit indirectly from the UK’s increased spending, as it manufactures amphibious vessels and nuclear-powered carriers and operates autonomous underwater vehicle facilities near Portsmouth.

Given the complexity and technological evolution in modern defence, some investors suggest that diversified funds and trusts may offer more balanced exposure than individual stocks. Options such as Finserve Global Defence & Security, and specialist exchange-traded funds focusing on defence, are gaining attention as means to participate in the sector’s anticipated growth.

As the UK government signals a renewed commitment to strengthening national defence, industry watchers and investors are closely observing how policy and budgetary decisions will unfold in the coming months.
