Since 7 October 2023, the cost of Israel’s war of annihilation against Gaza has become a central question in public debate—inside Israel and internationally. Official figures reveal a wide gap in how the total bill is calculated and how it is being financed, exposing a fragile balance between security demands and mounting economic pressures at home and abroad.
Conflicting Figures and Divergent Estimates
According to Calcalist, official bodies have presented inconsistent totals for the war’s cost. Finance Minister Bezalel Smotrich cited ~300 billion shekels (US$89.4bn), while the Finance Ministry’s Accountant-General Yahli Rotenberg estimated 140 billion shekels (US$41.7bn) through the end of 2024, rising to 200 billion (US$59.6bn) by end-2025. The Bank of Israel put the figure at ~247 billion shekels (US$73.6bn).
These discrepancies largely reflect methodological differences: some tallies capture only direct outlays to date, while others also include future liabilities—compensation for damage, reconstruction, relief spending, and wider losses to the economy. Variance also tracks the institution issuing the estimate (finance ministry, central bank, or independent international bodies).
In short, the gap between official accounting and economic reality underscores how complex it is to manage and finance the war, both fiscally and macro-economically.
The State Budget and a Widening Deficit
Israel’s 2025 state budget stands at ~620 billion shekels (US$184.8bn) with a deficit ceiling initially set at 4.9%. Of that, ~110 billion shekels (US$32.8bn) is earmarked for the Defence Ministry to cover the army’s needs and ongoing operations.
With the second phase of “Chariots of Gideon” approved, the Knesset Foreign Affairs and Security Committee authorised an additional 30 billion shekels (US$8.9bn) for defence emergencies. The Knesset then raised the 2025 deficit target to 5.2% of GDP (from 4.9%). As Reuters reported, the move responds to an extra 31 billion shekels (US$9.35bn) in military spending needs.
Economic correspondent Gad Lior (Yedioth Ahronoth) argues the budget offers little to society—light on reforms, heavy on decrees, and lacking genuine growth drivers. Measures include lifting VAT to 18%, freezing income-tax brackets, tweaks to property and insurance benefits (excluding child allowances), and deep cuts to critical civilian portfolios such as education, health, and social care.
Conversely, tens of billions more have been channelled to the army, while reconstruction funds for the north and south remain absent. There is insufficient financing for displaced residents, life-saving medicines, relieving school overcrowding, or housing for at-risk girls and the elderly. The bottom line, Lior contends: Israeli households bear a rising burden as the government prioritises defence outlays over essential public services.
How the War Is Being Financed
As outlined by Globes, Israel is funding the war through a mixed toolkit of domestic and external sources:
- Budget reallocations & internal transfers: Shifting funds away from civilian ministries (education, health, infrastructure) toward defence and emergency reserves, alongside a higher deficit and alternative financing channels.
- Taxation & borrowing: Expanding domestic and foreign debt and raising revenue via new tax measures or delaying civilian programmes—inflating public debt and its ratio to GDP.
- Direct U.S. support & emergency programmes: The United States remains Israel’s largest military backer, with urgent packages for munitions and equipment on accelerated timelines, alongside longer-term assistance commitments. A Watson Institute study estimates more than US$22bn in U.S. military aid from the war’s outset through end-2024, in addition to the customary US$5bn annually (per Calcalist).
- With early 2025 and the start of Donald Trump’s presidency, Israel’s Defence Ministry signed with Rafael to ramp up Iron Dome missile production under a U.S. deal worth US$8.7bn to bolster air-defence systems, plus an additional US$5.2bn for advanced defensive capabilities.
- Arms-industry revenue & exports: Israeli defence exports hit a record in 2024—around US$14–15bn—easing part of the fiscal strain, though far from covering total costs.
- Private contributions & donations: Limited support from organisations or friendly states and emergency funding via private or international channels—modest relative to the overall bill.
2025–2026 Outlook: Rising Risks
If current spending continues unabated without new revenue sources or a scaling-down of operations, editor Nati Tucker (TheMarker) warns 2026 could become a decisive stress point for Israel’s budget, with escalating deficit risks and reserve erosion.
He argues that fiscal authorities must standardise cost methodologies, report transparently, and adopt balanced reform plans that protect social services. Beyond that, Israel needs to stimulate non-defence growth—driving investment into productive civilian sectors—and craft a 2026 emergency plan for economic recovery, whether operations wind down or extend further.
Editorial Note
These figures and policy choices highlight a stark reality: the human cost in Gaza is compounded by an Israeli fiscal model that diverts civilian resources to sustain a prolonged war. The economic burden—in taxes, deficit expansion, and social-service cuts—falls on ordinary people, while military spending and arms-industry revenues are prioritised. For readers tracking the political economy of the Gaza war, the financing mechanisms matter as much as battlefield events; they shape incentives, prolong conflict, and postpone justice for Palestinians under siege.
