Background Info:

Official Israeli statements and budget reports often only focus on the explicit (accounting) cost of the Gaza war, which is limited to defense spending and emergency aid, and is approximately 15–20 billion dollars. This represents only: daily operation expenses, ammunition, logistics, and direct reconstruction payments. (Middle East Monitor)
However, several studies show that this limited view heavily undervalues the real loss. The Bank of Israel itself has reported weekly economic losses of about NIS 2.3 billion (around 600 million dollars) because of the people at war abandoning their work and production being hindered. (Times of Israel) Over months of this being the case, the implicit cost alone exceeds 60 billion dollars.

The Arab Center DC and Middle East Monitor both cite official estimates putting combined explicit and implicit costs near NIS 250 billion (about 67 billion dollars) by the end of 2024, showing that total economic losses were multiple times larger than the defense budget alone. (Arab Center DC, Middle East Monitor)

Morever, the RAND Corporation predicts up to 400 billion dollars in lost output over the next decade once, investment slowdown, productivity slowdown, and reduced growth are all taken into account. (RAND) These findings show that the true economic issues are not linear but rather exponential; as they accumulate through abor shortages, investors losing their trust, and debt buildup.

Long story short, official figures are quite misleading as they capture only the accounting cost, while the real economic cost, including lost GDP, the projected decline in production, and lowered productivity, is many times higher. Focusing only on explicit expenses misleads people into thinking the loss is quite manageable, hiding the actual economic downturn and social consequences that the upcoming years will show.
