Fiscal breakeven price

An estimate, published by international institutions rather than by the states themselves, of the price per barrel at which a producing government's budget balances. It is the most useful single piece of arithmetic for reading what an oil move means to a producing economy, because it converts a price into a fiscal position: above the level the budget runs a surplus, below it a deficit that has to be funded from reserves, from borrowing or by cutting spending.

It is a property of the budget rather than of the oil field. Two states with similar production costs can carry very different breakeven levels because one has committed to more spending, and a state's breakeven moves when its budget changes even though nothing about the oil benchmark has moved. Estimates also differ between the institutions producing them, because each makes its own assumptions about production volumes, non oil revenue and what counts as spending.

The chain from there to a screen is longer than it looks. A deficit does not force an immediate response, since reserves and debt markets absorb it, and in an economy running a currency peg the effect appears in fiscal and credit conditions rather than in the exchange rate, which is fixed. This is why an oil price can be the most consequential number in a regional economy and not the number that moves a regional screen on any given morning.
