Why is oil hitting $100 again and what does it mean for gas prices?

Oil prices do affect pump prices, but there's usually a lag and it depends on refinery capacity and global supply disruptions rather than spot prices alone. A barrel at $100 typically translates to maybe $3 - 4 per gallon or so at the pump in the US, though it varies by region and current market conditions. The real impact depends on whether this is temporary geopolitical noise or signals sustained supply issues - a brief spike might not move prices much, but prolonged disruption would. Gas prices tend to reflect expectations about where oil will settle, so if markets think this is temporary, pump prices might stay relatively stable even if crude stays elevated for a few weeks.

Don't assume the pump price will jump immediately or proportionally to what you see on the news - that's the biggest mistake people make when they freak out about barrel prices spiking.

The real wildcard here is refinery capacity and distribution logistics, not just the crude cost itself. You could have $100 oil but if refineries are running at full capacity and there's no supply crunch, the impact at the pump stays moderate. Conversely, if geopolitical stuff actually disrupts shipping routes or refinery operations shut down unexpectedly, that's when you get the nasty price jumps. The other answers nailed that there's a lag, but here's what they glossed over: futures markets already price in a lot of the risk, so by the time oil actually hits $100, some of that impact has already worked into wholesale fuel costs. You're not starting from zero.

What actually matters for your wallet is whether this becomes a sustained situation or a spike that resolves in weeks. A month of $100 oil is annoying but manageable for most consumers. If it stays elevated for quarters because supply genuinely stays constrained, then yeah, you're looking at gas prices climbing noticeably - maybe another 30-50 cents a gallon in the US, depending on your region. But "how bad could it get" really depends on whether whatever's happening in the Middle East escalates further into actual supply disruption versus staying as geopolitical tension that markets price in and move past.
