Shares in Rolls-Royce and BAE Systems climbed sharply on Monday following the announcement of a new defence investment plan by Prime Minister Keir Starmer.
The market move reflects investor optimism that the government’s commitment will provide a durable tailwind for the UK’s largest defence and aerospace firms.
The rally underscores the growing market conviction that UK defence spending is set to accelerate, with investors rewarding companies positioned to benefit from long-term contracts and infrastructure upgrades.
Rolls-Royce, with its dual exposure to civil aviation recovery and military engine programmes, saw particular buying interest alongside BAE Systems, the country’s primary defence contractor.
This development adds to a broader theme of geopolitical realignment driving capital flows into defence equities.
As global tensions persist, governments are increasingly prioritising security budgets, creating a favorable environment for firms with strong order books and strategic government relationships.
