Defence spending up, your taxes up — what the 5% NATO target means at the till
NATO's June 2025 Hague summit raised the alliance target to 5% of GDP. That money has to come from somewhere. A calm reading of which household budgets get squeezed first.
The number that changes everything else
At the Hague summit in June 2025, NATO members committed to raise core defence spending to 3.5% of GDP, with another 1.5% on broader resilience (cyber, infrastructure, logistics). For most European countries that means roughly doubling current spend over five years.
Half a trillion euros annually, across the alliance. That money is not created. It is redirected.
This isn't a political post. We don't take sides on whether the target is right. We do think a household is better off knowing how this maths reaches their bank account.
Where the redirect comes from — three channels
- Higher taxes. The Netherlands, Germany, Poland and the UK have signalled VAT or income-tax increases in 2026–2028 to fund the increase. Average impact on a median-income household: €280–€650 per year, depending on country.
- Reduced spending elsewhere. Health, education, infrastructure renovation, climate subsidies. The household effect is invisible but real: longer waiting lists, fewer heat-pump grants, slower public transport upgrades, more potholes.
- Bond markets. Some of it gets borrowed. That puts upward pressure on long rates. Variable-rate mortgages in 2027 will likely be ~0.4 pp higher than they would have been without the defence build-up.
ECB's spring 2026 financial stability report explicitly flags this as a "moderate but persistent inflationary undercurrent for the next 5–7 years."
What this is not
This is not the apocalypse. This is a structural shift in European fiscal posture — the kind of thing that happens slowly, in a budget line at a time, and never makes the front page in a way the average citizen connects to their own situation.
The households that handle this well are the ones who: - Build a 3-month emergency fund. Standard advice, but only ~40% of EU households actually have one (ECB consumer survey 2025). The combination of higher taxes + higher mortgage rates + occasional energy spikes is what an emergency fund exists for. - Don't lock into long fixed-rate consumer debt at peak rates. If you're refinancing a mortgage in 2026, take advice. The yield curve is not behaving like 2010s curves. - Treat real wages as flat. Most European households should plan as if real disposable income holds steady, not grows, for the next 3–4 years. Lifestyle expansion ("we earn more so we'll upgrade") is the slow erosion that catches families out.
The geopolitical reality, briefly
We are in the early years of a multi-decade rearmament cycle. Whether you think this is necessary, excessive, or overdue is not the question this briefing answers. The question we answer: how does this reach an ordinary European household, and what should they do about it.
The answer is the same one this briefing always gives. Build margin. Reduce fragility. Notice what's changing before it surprises you.
One thing this week: check your emergency fund balance. If it's less than 3 months of essential expenses, decide one place to cut €50/month and start the auto-transfer.
