European Defense Stocks Rally Ahead of NATO Summit as Multiple Nations' Military Spending Pledges Boost Confidence
Alina Collins
Goldman Sachs' European defense basket has bounced 17% from its late-June low, betting the NATO Ankara summit will deliver firmer spending pledges — yet the sector is up only 3.4% year-to-date versus nearly 10% for the Stoxx 600, and the core question remains whether promises turn into actual contracts.
A 17% bounce — what's driving it?
Goldman's European defense basket rallied 17% from its late-June trough, hitting a one-month-plus high.
The catalyst: the upcoming NATO Ankara summit. Morgan Stanley analyst Marie-Ange Riggio's team called it "a key catalyst for the European defense sector" and said now is "an attractive entry point."
This means → the market is front-running a policy signal. If the summit delivers above-expectation spending commitments, the rally extends; if it doesn't, this 17% may be the ceiling.
Only 3.4% year-to-date — what's holding the sector back?
Defense stocks have gained just 3.4% this year, badly trailing the Stoxx 600's near-10% rise.
The core doubt: whether governments' spending pledges will actually convert into real outlays. In plain terms = saying you'll spend money and actually signing procurement contracts are two different things.
Capital flows are also shifting: money is rotating out of heavy land-army names like Rheinmetall and CSG into air defense and military-tech plays. This reflects a market bet that future budgets will favor missile defense and technology upgrades over traditional armor.
Which countries are already writing checks?
Italy: La Repubblica reports a potential €17 billion (~$19.4 billion) increase in military and security spending within two years. Mediobanca analyst Alessandro Pozzi sees Leonardo and Fincantieri as direct beneficiaries.
UK: Last week's defense investment plan pledged an extra £15 billion (~$20 billion) for military modernization. Morgan Stanley expects BAE Systems and Rolls-Royce to benefit.
Germany: Thyssenkrupp Marine Systems is in line for a €12 billion warship contract, and Canada has named it preferred supplier for a submarine program potentially worth C$70 billion over decades — the stock is up 25% this month on those signals.
Nearly 500% since 2022 — what's the long-cycle logic?
Since Russia's 2022 invasion of Ukraine, Goldman's defense basket has gained close to 500%; the 2025 full-year return alone was 90%.
Last year, under pressure from Trump, NATO allies agreed to raise defense spending to 5% of GDP by 2035 — with 3.5% earmarked for military equipment and personnel. This means → this is not a one-off stimulus but a decade-long spending upcycle.
In plain terms = as long as geopolitical tension persists and the U.S. keeps pressing, European military budgets can only go up. The sector's long-term case rests on that trajectory, not on any single summit.
What else to watch at the summit?
Trump is expected to keep pushing allies toward the 5% GDP target; Zelensky may also use the occasion to press Western partners for more weapons.
This means → the summit's real test is not "whether to spend" — that consensus already exists — but whether specific dollar amounts and timelines exceed what the market has priced in.
Rheinmetall was hit when Germany abruptly halted a frigate project; tank maker KNDS then postponed its IPO. These setbacks show that even within a structural uptrend, individual program cancellations can still deliver sharp short-term blows to single stocks.
