National Supply Pressure Index

A composite score summarising whether upstream supply conditions may push Australian pump prices higher or lower.

Moderate supply pressure suggests wholesale costs are relatively stable this week, but rising retail velocity means pump prices may still climb in the short term.

For Melbourne drivers, this national score is the backdrop, not the bowser price — local retail competition and the weekly price cycle still decide what you pay on a given day. Compare today's board against the trend by checking the live fuel map or your suburb directory listing.

Frequently asked questions

How often does the supply pressure index update?
The index refreshes daily from the underlying component data — see the score components below and the full methodology for how each weighting is calculated.
What does a high vs low supply pressure score mean?
A higher score signals upstream conditions (refining, freight, currency, and supply components) that tend to push Australian pump prices higher; a lower score signals conditions more likely to ease prices. It is a directional signal, not a price forecast.
