A: While motorists may try to tie current events in a local area to gas price fluctuations, rarely are these assumptions correct, due to the global nature of oil and gasoline markets that are affected by much larger events only, Patrick DeHaan, senior petroleum analyst for GasBuddy.com, told Q&A on the News via email.

“In this case, prices rising has nothing to do with a shutdown of an interstate and everything to do with seasonal factors and rising oil prices,” he wrote.

Over the last few weeks, oil prices have risen $5 per barrel (nearly 13 percent) on the concern that inventories of crude oil are tightening, DeHaan said.

“In addition, the transition to more expensive summer gasoline is taking hold,” he wrote. “These two factors are responsible for the bulk of the increase, and more increases at retail pumps are likely until Memorial Day or so, when things usually cool off.”
