How Much Are Gas Prices Driving Inflation?

Gas prices have been going up and they've gone up a lot over the last six months or nine months. The market magic here is basically that there is trading that happens around a limited amount of natural gas that's available. And traders are making essentially bets based on whether they think that kind of supply will be available in the future or not. If they think it's not going to be available, they'll pay a lot more for it right now; if they think it could be available later, then they're going to pay a lot less.
