NATO’s 5 Percent Pledge Meets Its First Real Budget Test

NATO’s July 2026 spending estimates put only five of 32 allies at or above the 3.5% of GDP core-defence bar set at The Hague. Lithuania, Estonia, Latvia, Poland and Greece already clear that harder line. Most of the rest, including the United States at 3.17% and Germany at 2.69%, do not.

The 2% of GDP test that ate a decade of summits is no longer the live fight. In June 2025 allies promised 5% of GDP by 2035, split between core forces and a broader security bucket. The first year of that path shows a real surge, a headline padded by accounting, and a political bill that has landed on Spain.

The 2 Percent Test Is Already Over

Alliance tables released as leaders met in Ankara on 8 July 2026 still use the old 2% line as a floor, and they show how far the floor has moved. European allies and Canada are expected to spend $634 billion on defence in 2026, up from $571 billion in 2025, an 11% rise in real terms after a nearly 20% jump the year before. The alliance’s average core spend is heading for 2.86% of GDP in 2026.

That is a different world from 2014, when those same European allies and Canada put 1.4% of their combined GDP into defence. By 2025 that share had reached 2.3%, more than $571 billion in 2021 prices, after a nominal increase of about $139 billion in a single year. The United States still supplies about 57% of NATO’s total defence outlays, about $1.03 trillion of an alliance total near $1.8 trillion, but that share is no longer two-thirds of the pile.

Secretary General Mark Rutte used a larger figure in Ankara, saying European allies and Canada were already investing around 4% of GDP in “defence and security” one year into a 10-year project. That 4% is the combined Hague scoreboard. It is not the 3.5% core-defence line that buys brigades, munitions and aircraft, and it is not the 2.86% average on core budgets. The gap between those three numbers is the argument.

2026 CORE DEFENCE SHARES

NATO’s July 2026 estimates put Belgium, Czechia, Slovakia, Luxembourg and Croatia with Spain in a 2.0% to 2.03% cluster. Seventeen allies are on course to meet the separate 1.5% bucket for infrastructure, networks, civil preparedness and the defence industrial base. The soft bucket is doing a lot of work in any speech that treats 5% as already in sight.

How the 5 Percent Deal Was Written

NATO did not invent a GDP target in 2025. Defence ministers adopted a 2% guideline in 2006. Heads of government turned it into a political pledge at the Wales Summit in 2014, after Russia seized Crimea, and added a second rule that at least 20% of defence budgets should go to major equipment and related research. The Vilnius Summit in 2023 made the 2% line an enduring annual floor and said many allies would need to go higher. The Hague made that warning into a new ceiling.

THE PLEDGES THAT CAME DUE

1. 4 April 1949: Twelve countries sign the Washington Treaty. Article 5 treats an attack on one as an attack on all.
2. 2014 Wales Summit: Allies pledge to move towards 2% of GDP on defence and 20% of that spend on major equipment.
3. 2023 Vilnius Summit: The 2% floor is made enduring; leaders say many will need to spend more than 2%.
4. 25 June 2025, The Hague: Allies commit to 5% of GDP by 2035, with at least 3.5% on core defence and up to 1.5% on broader security-related investment, and a review in 2029. Direct aid to Ukraine’s forces and defence industry may count.
5. 8 July 2026, Ankara: Leaders shift the language from setting targets to delivering plans, contracts and production.

The Hague text is short and built around money. It restates an “ironclad commitment” to Article 5, names Russia as a long-term threat and terrorism as a persistent one, and ties the new spend to Article 3 of the Washington Treaty, the duty to maintain the capacity to resist attack. Allies also promised annual plans with a “credible, incremental path” to 3.5% core. That paperwork, not another family photo, is 5 percent pledge in 2026 as a budget exercise rather than a slogan.

Five Allies Already Clear the Harder Bar

The countries that already live next to Russia did not wait for 2035. Lithuania’s core spend is estimated at 5.33% of GDP in 2026, with Estonia at 5.10%, Latvia at 4.92% and Poland at 4.68%. Greece, a long-time high spender for reasons that have more to do with the Aegean than the Suwałki Gap, is at 3.65%. Denmark is a rounding error short at 3.49%.

Those shares are not accounting tricks in the 1.5% bucket. They are core defence as NATO defines it: armed forces, equipment, pensions paid to military retirees, and net contributions to common infrastructure. Front-line governments have been borrowing to get there, and they have been doing it while larger western economies still treat 3.5% as a 2030s problem.

Germany is the swing state in that story. Chancellor Friedrich Merz’s government has told the alliance it will hit 3.5% core by 2029, six years ahead of the Hague deadline, and Rutte called that plan “an extraordinary achievement” in Berlin in July 2026, saying “Germany leads and Germany delivers.” NATO’s 2026 estimate still puts Berlin at 2.69% this budget year, second in dollars at about $147 billion, with a stated aim to grow the Bundeswehr from 182,000 to 260,000 professional soldiers by 2035. The praise is for a trajectory, not for a 2026 crossing of the line.

The United States, the country that demanded the new bar, is estimated at 3.17% of GDP in 2026. That is above the old 2% floor and below the new 3.5% core target. Any lecture that treats 3.5% as a European homework assignment has to live with that number too. U.S. Secretary of Defense Pete Hegseth told a June 2026 defence ministerial that some members still lacked “a credible path” to the Hague goals. The American path is not a straight line either.

Growth is also slowing. After the nearly 20% real increase in 2025, the 11% rise expected in 2026 is still large and already less steep. Rutte told reporters that 2025 and 2026 together add $258 billion in extra European and Canadian defence investment. The cash is arriving. The question is whether factories, crews and ammunition stocks arrive with it.

Spain Holds the 2.1 Percent Line

Prime Minister Pedro Sánchez is the named holdout, and he is not hiding. NATO’s 2026 estimate puts Spain at 2.0% of GDP on core defence, in the cluster that has only just reached the Wales floor. Madrid’s own argument is different. Sánchez says Spain agreed with NATO on the capabilities it must provide, and that those outputs cost 2.1% of GDP, not 5%.

When the issue of the 5% figure was raised last year, Spain had already agreed with NATO on the capabilities we needed to make available to the Alliance to address those challenges; the cost of contributing those capabilities amounted to 2.1% of our Gross Domestic Product.

Pedro Sánchez, Prime Minister of Spain, Ankara press conference, 8 July 2026

He dated the climb from 0.9% of GDP in 2018 to 2% in 2026, and said the Alliance’s Defence Policy and Planning Committee had judged Spain to have met its 2026 capability targets, ranking seventh of 32. He put 3,000 Spanish personnel on NATO missions as of early June, called Spain the largest troop contributor on the eastern flank’s ground force, and said Madrid would join the forward presence in Finland. A €10.4 billion industrial and security plan is the domestic vehicle. Ukraine aid from Spain totals €3.8 billion since 2022, with more than 9,000 Ukrainian troops trained on Spanish soil.

That is a capability brief, not a GDP brief, and it is why Spain is the political target. President Donald Trump has spent two years treating the 5% line as a loyalty test. After The Hague he called Spain’s wish to stay near 2% “terrible” and tied it to trade talks. In Ankara a reporter put still harsher public attacks to Sánchez, including talk of cutting relations and throwing Spain out of the alliance. Sánchez said he later had a casual conversation with Trump about football and the World Cup, and that Madrid would meet the noise “with calm and patience.”

The wider argument on X and in allied capitals has fused money with loyalty. Spain is the country that put a number on the exception, so it absorbs anger that could as easily point at Slovenia’s 1.61% core estimate or at several other 2.0% neighbours. Sánchez is also right that a 5% GDP rule, applied blindly, collides with social budgets in a way a capability catalogue does not. The alliance has not chosen between those two measuring sticks. It is running both, and the 2029 review is when that double bookkeeping gets opened.

Common Budgets Are a Rounding Error

The GDP fight is almost entirely about national defence ministries, not the cheque sent to Brussels. NATO’s three common pots, the civil budget, the military budget and the Security Investment Programme, ran to around EUR 4.6 billion in 2025. Allies set the 2025 civil budget at EUR 483.3 million and the military budget at EUR 2.37 billion, and the headquarters has said those two lines together are less than 0.02% of allied defence spending.

WHAT THE COMMON POTS PAY

• Civil budget: NATO Headquarters staff, consultation and the civilian running of the organization, EUR 483.3 million in 2025.
• Military budget: The NATO command structure, operations and shared military running costs, EUR 2.37 billion in 2025.
• Security Investment Programme: Shared infrastructure and capabilities, making up the rest of the around EUR 4.6 billion common-fund total.
• Cost shares: A GNI-based NATO common funding formula put the United States and Germany at 15.8813% each through 31 December 2025, with the United Kingdom at 10.9626% and France at 10.1940%.

When a politician says a country “pays for NATO,” that sentence is usually mixing a few billion euros of shared bills with more than a trillion dollars of national force structure. The United States does not fund Germany’s brigades through the common budget, and Spain does not settle its 2% argument by tweaking a 5.8211% common-fund share. The real money is in national procurement, pay, ammunition and bases. That is why The Hague had to rewrite the GDP rule rather than the dues table.

Ankara Turned Pledges Into Purchase Orders

Rutte’s line after Ankara was that “NATO delivers” and that the focus had “shifted decisively from setting targets to delivering results.” The summit declaration said European allies and Canada raised core-defence investment by more than $139 billion in 2025, matching the nominal increase on NATO’s own topic page, and it announced more than $50 billion in new procurements. The secretary general put the industry-forum total at over EUR 50 billion in procurements and called the rebalancing “NATO 3.0.”

CONTRACTS ANNOUNCED IN ANKARA

• Industry forum: Over EUR 50 billion in new procurement deals, with ministers and more than 100 companies in the room.
• Drone Edge: USD 40 billion over five years for counter-uncrewed systems and operator training.
• Fuel network: EUR 27 billion to modernise storage and distribution, including pipelines toward the eastern flank.
• Ukraine: At least EUR 70 billion in military equipment, assistance and training in 2026, with a pledge to match that in 2027.
• Shared fleets: The 10th Airbus A330 tanker for the multinational MRTT fleet, Northrop Grumman Triton drones for maritime surveillance, and a joint buy of Saab GlobalEye aircraft for airborne early warning.

Those lines are the part of the 5% story that cannot be faked with a road-repair invoice. They also show who collects. Tankers, surveillance drones and airborne radar are transatlantic products. Eastern pipeline fuel and counter-drone kits are the items front-line staffs actually file as shortages. Rutte’s pitch to banks, a call for more private capital in defence, is an admission that tax-funded orders still outrun plant capacity.

The 2029 Review Sits on the Calendar

The Hague deal built in an escape hatch. Allies will review “the trajectory and balance of spending” in 2029 against the strategic picture and updated capability targets, a date that falls after the next U.S. presidential election. Until then, annual plans are the enforcement tool, and they are political documents. A country can look compliant on the 5% headline by filling the 1.5% bucket while its army still waits on shells. A country can also, as Spain claims, hit the capability catalogue at 2.1% and still be treated as a debtor.

The 2029 review will have to say which of those results counts. If the measure stays GDP, Slovenia’s 1.61% and Spain’s 2.0% will dominate the argument even if eastern flank states are already living at 5%. If the measure shifts to outputs, Merz’s 2029 3.5% plan and the Ankara contracts will matter more than any round-number slogan. The alliance wrote both tests into the same communiqué. It now has three years of budgets to show which one it meant.
