Yes. Spot margins today across our platform are kind of ranging on average between $0.08, $0.12 a gallon, somewhere in that range on May and June at this point. And post that, mid- to high single digits, really kind of across the platform, maybe some a little bit lower, a little bit higher in some places, all inclusive. And so that has come off significantly from the lows. I mean we saw mid-teens to -- and even in the negative 20s across the curve, and we've seen a significant rally on the back end of the curve as we -- typically, when we see those type of numbers, it's not going to -- it won't hold very long. So you have a carry in the corn market and we had a flat to inverted ethanol market, and that's kind of changed a little bit.
We have to see more contribution from the simple crush as we've seen less contribution going forward from things like corn oil and distillers and those type of things, although natural gas is now a significant tailwind price-wise. So generally speaking, from a demand perspective, we've seen some pretty good weeks on driving demand coming out of winter. We have also now, as we enter into more of a summer driving season, hopefully, get ourselves well positioned as an industry to take advantage of that. We remain well over $1 under -- while we remain $1 or so under RBOB and with the RIN values in the mid-50s or so at any given point, that's $1.50 blend credit. So we've seen blends as high as 10.5% here recently.
So generally speaking, the base business in the U.S. and gas demand hopefully recovers kind of post last week and the week before, as we get into driving season, especially with higher [indiscernible] rates and less capacity. And we're very optimistic that the summer will act as typically the same that it has. On top of that, we're so well priced in the world on ethanol today.
And I think more importantly, when you look at the last half of the year, we actually see Brazil as an opportunity to price into even with the tariffs that are in place as they do not have the excess ethanol capacity at this point to take care of all their back half demand. So when you kind of line it all up and you look at -- if we can just keep production steady as an industry and maintain some self-discipline I think where we can set ourselves up for a continuing draw as we kind of come through the end of this maintenance season. But generally speaking, margins are positive at this time of the year across the board fully. And we're optimistic that, that can continue to improve.
Jim, did you have something?
