Oil discovery news raises prices before extraction begins
News of large oil and gas discoveries raises core consumer prices before extraction begins, a Bank for International Settlements (BIS) paper published on October 23, 2026 finds. Inflation rises mainly under inflexible exchange rates.
Prices move before production
The researchers compile 1,309 large oil and gas discoveries across 79 economies from 1980 to 2019, focusing on discoveries with realized production lags of at least five years.
Panel local projections trace responses over the following decade.
Core consumer prices rise persistently, with about half the total increase occurring before extraction begins.
Non-tradable goods and services drive the response; tradable and producer prices barely change.
Real activity expands ahead of production, consistent with households and firms anticipating higher future income.
Using dated discoveries as observable news separates anticipation from physical supply changes and avoids model-dependent statistical assumptions used to identify unobserved news shocks.
Exchange rates absorb demand pressure
The real exchange rate appreciates persistently after discoveries.
The current account initially deteriorates as domestic demand increases, then moves into surplus when production begins.
Inflation rises mainly under inflexible exchange rate regimes and is largely absent under flexible regimes.
A three-sector New Keynesian model of a small open economy explains the contrast: flexible exchange rates absorb demand pressure through currency appreciation, while inflexible regimes experience higher domestic inflation.
Future supply, present inflation
Higher future output does not mean lower prices today in these findings.
Anticipated income raises domestic demand before extraction adds physical supply.
The exchange rate regime determines whether that pressure appears as currency appreciation or domestic inflation in the model.
