What this driver is
An oil supply shock occurs when production is cut, a key supply route is disrupted, or geopolitical events reduce the availability of oil faster than demand falls. The effect is an increase in the oil price, which flows through to energy sector revenue and creates input cost pressure across industries that use oil as a fuel or feedstock.
What activates it
The engine watches USO (US oil fund ETF) and tracks its five-day return. A strong positive return in USO signals that oil prices have moved higher. Combined with context from the macro event layer, the engine assesses whether the move looks like a supply disruption or a demand increase.
What it connects to
A supply shock benefits:
- Oil producers — revenue rises when the commodity price rises
- Oil field services — demand for drilling and production services increases
- Refined products — margins on gasoline and diesel can widen depending on refinery dynamics
A supply shock creates headwinds for:
- Airlines and transport — jet fuel and diesel are direct cost inputs
- Consumer discretionary — higher gasoline prices reduce disposable income
The OPEC factor
Many oil supply shocks in recent years have originated from OPEC+ production decisions. The engine's macro event layer classifies OPEC announcements and Middle East conflict reports. When an event is tagged as an oil supply disruption, the macro evidence layer reinforces the USO price signal.
How Decifer tracks it
USO five-day returns are computed each cycle. The macro event layer provides geopolitical and commodity event classification. The engine combines both to assess whether the oil move has supply-side characteristics.
