1. And I thought I would have a normal day today! Going to focus on the implications of the SRE denial decision in this thread. Lots of unknowns about the E15 pump announcement. So sticking with what is known.
2. The implications of the SRE denial is far-reaching with regard to PAST and FUTURE implementation of the RFS mandates. Without the gap SREs, nationwide application of the 10th circuit decision means that very few of the SREs issued since 2011 or 2012 are valid. Poof.
3. I recall some in the oil refining business saying I was out to lunch that the 10th Circuit decision could blow up the SRE program. Done blowed up now! But honestly this was inevitable.
4. For a detailed discussion of the 10th Circuit decision please see this #FDD from last March by Jonathan Coppess and myself: farmdocdaily.illinois.edu/2020/03/epa-an…
5. This slide from my @OPISBiofuels talk this morning is the key part of the #FDD article. Two federal appeals courts have now concurred that the "North Star" of the RFS is that Congress intended the RFS to be a market forcing policy that favors biofuels. That simple. Image
@OPISBiofuels 6. Without the gap SREs or a reversal of the 10th Circuit ruling, the first thing to realize is that the vast majority of SREs awarded for 2016-2018 under the Trump EPA are now invalid. EPA has said it does not want to revisit but I will be very surprised if ag does not.
@OPISBiofuels 6. I don't know what the thinking is inside ag and biofuel groups about trying to claw back the lost SRE gallons from 2016-2018, but legally they certainly have a case to be made. Don't be surprised if they try. The strategy would be to try to get them added to future years.
@OPISBiofuels 7. Here is the record of SRE exempted RVOs going back to 2013. A total of 4.04 billion gallons of RVO (mandates) exemptions in 2016-18 years. That is a big fat target for ag and biofuel groups. Will they try to get them retroactively reinstated? Image
@OPISBiofuels @joey2x2x @SethMeyerMU @mwalkerrfs Good question. I am not sure. Perhaps others with more knowledge can say.
@OPISBiofuels 8. A final kick in the pants for the oil refining industry with the SRE decision. The EPA had already agreed in the final 2020 RVO rulemaking to 770 million gallons of reallocation for expected 2020 SREs. This is effectively clawback of past SRE exemptions without 2020 SREs.
@OPISBiofuels 9. So, the disaster of the SRE program for ag and biofuel overall turns out to not be nearly as bad as it could have been. As of today, the net total lost RVO is 3.27 billion gallons. Yes, that is a lot, but a far cry from what it could have been if SREs continued.
@OPISBiofuels 10. If allowed to run uninterrupted through 2022, the SRE program would likely have reduced RVOs by at least 10 billion gallons over 2016-2022. Looking forward from here, things are gonna get very interesting in the #RFSwars!

1. I guess today is the day to talk about corn yields. Just received an email from @aaea announcing a new Choices article "A Slowdown in US Crop Yield Growth" by David Boussios. Here is the link: choicesmagazine.org/choices-magazi…
2. The author of the Choices article argues: "The statistical evidence of a productivity slowdown in crop yield growth builds each year. The linear yield growth trends since 2013 for corn, soybeans, and wheat are all statistically lower than one starting in 1988. Models, forecasts, market participants, and policy makers should consider that yields in the future will probably be lower than forecasted by the USDA and that extrapolating trends into the future without revision is problematic."
3. This argument is especially interesting because I have seen similar arguments in the grain trade in the last few years. We can all agree that the US average corn yield has been relatively flat since around 2013. That is obvious looking at a chart of corn yields. But one has to be extremely careful in then leaping to the conclusion that productivity growth in corn yields has also slowed. The reason is that runs of poor or good weather can mask the true underlying trend in small samples of years.

1. Recommended Reading for the Day: Fascinating new FDD from my colleagues on the farmdoc team, led by Carl Zulauf. Long-term look at real crop prices. farmdocdaily.illinois.edu/2023/10/the-po…
2. It has long been a staple of economic thinking that real (inflation adjusted) commodity prices have a strong tendency to decline over time. Probably the most famous example of in this regard is the bet about real commodity prices between Julian Simon and Paul Ehrlich in 1980. See the details here:
3. Carl and team put together the data for a USDA index of real crop prices going back to 1912. This is the chart shown below. Lots of interesting history here, but the 30 year period of stable real crop prices that began around 1990 is unmistakable. The question is whether this is a pause in a very long run downward trend or something new.

1. Excited to announce that the band is back together! Actually, talked Darrel Good into coming out of retirement to work on this FDD: "The New Era of Crop Prices: A 15-Year Review." farmdocdaily.illinois.edu/2023/09/the-ne…
2. When crop prices started to take off in 2006-07, a huge question was whether this was just another spike like we had seen so many other times, or was this the beginning of a permanent jump in the level of average prices, like in 1973. Image
3. For some reason (temporary insanity?), Darrel and I decided to stick our necks out and predict that a new era in crop prices was afoot AND make specific predictions for the average price and trading range in the new era. As this chart shows, we did not have much data to go on.

1. Ok, I have hopefully convinced you that the RIN cliff scenario is a logical possibility. Now what are the chances of it actually happening? The first step is to estimate QM in the graph below. Turns out the proposed RVOs released by EPA last December are the place to start. Image
2. We can use the proposed RVOs to come up with a defensible estimate of the maximum demand for biomass-based diesel (BBD) for 2023, 2024, and 2025. We can do this because we know mandates are and will be binding. Image
3. I will leave the details of the computations to the article. Suffice it to say that under the EPA's preliminary rulemaking, the max amount of BBD needed is about 4BG each year. That is national demand for sum of RD and BD. Image

1. Ok, had to take a brief pause for the cause (a meeting). Anyway, diving into the heart of the RIN cliff idea in this thread based on our latest FDD. farmdocdaily.illinois.edu/2023/05/is-the…
2. Here is how RIN pricing works when BBD production is equal to the mandated quantity. In this case, looking at an example of D4 biodiesel RIN pricing on May 4, 2023. Predicted D4 RIN price is $1.61 and actual on this date is $1.58. Pretty close. Everything A OK. Image
3. But what if for some exogenous reason, biomass-based diesel (BBD) production is pushed past the RFS mandate? This is the RIN cliff scenario. New market equilibrium is given by intersection of demand w/tax credit and fixed QRC supply of BDD. Red line becomes supply curve. Image

1. Our latest FDD on the renewable diesel boom is titled "Is the U.S. Renewable Fuel Standard in Danger of Going Over a RIN Cliff?" That should get your attention this morning. It is going to take me several twitter threads to go through the highlights.

farmdocdaily.illinois.edu/2023/05/is-the…
2. In this thread, I am going to go through the first part of our analysis. Start with the very basics of binding and non-binding RFS mandates. In a standard supply/demand framework, here is a binding mandate. Image
3. A binding mandate "binds" in economic terms because the mandate volume exceeds the competitive market equilibrium quanitity. To get the higher than equilibrium Q produced, producers have to be offered a higher price and consumers a lower price. Image
