What is RVP?

Reid Vapor Pressure (RVP) is a measure of gasoline volatility, or how it evaporates. The US Environmental Protection Agency regulates the RVP of gasoline sold at retail stations from June 1 to September 15 to reduce emissions. This results in seasonal RVP shifts in the spring and fall. The higher the RVP, the higher the levels of vaporization, and vice versa. RVP levels are lower in the summer than they are in the winter.

How do we assess Platts RVP?

Every Platts gasoline assessment S&P Global Commodity Insights is linked to its corresponding RVP. S&P Global follows the pipeline specification and US regulation to determine the RVP being assessed. As a rule, RVP increases in the fall/winter as temperatures cool and decreases in the spring/summer.

In the spring of 2020, S&P Global Commodity Insights also launched a USGC RVP adjustment calculation that reflects the value of 1 psi RVP. During the spring, it reflects the value of 1 psi lower than the current assessed RVP while in the winter, it measures 1 psi higher than the current lowest RVP.
