Ryan Cummings @weakinstrument.bsky.social · 25/09/20262/2 One thing I want to emphasize: it is very, very difficult for both observers *and the firms themselves* to understand what the ROI of these projects even is, which is a bit wild considering how much is being spent.

Ryan Cummings @weakinstrument.bsky.social · 24/09/2026Ok ran a couple back on the envelope calcs and don't think prices would increase domestically (in the short run), and the market's reaction to the alleged export ban quite a bit of price decreases. international prices would still increase; refining runs may or may not be cut. 040
Ryan Cummings @weakinstrument.bsky.social · 23/09/2026The Trump Administration continuing with their "all costs, little to no benefits" philosophy of economic policymaking. They are consistent if nothing else, although you do not, in fact, have to hand it to them. 1121
Ryan Cummings @weakinstrument.bsky.social · 23/09/2026A 90 day diesel export ban would truly be a storied piece of policymaking because it would quite literally be the worst of both worlds; refiners would cut runs, throw excess production into storage (instead of sending to rest of US), *raising* prices domestically AND internationally. 1257
Ryan Cummings @weakinstrument.bsky.social · 22/09/2026Historically yes, although the Trump Admin issues a Jones Act waiver which negates this issue. The problem is that if the supply of seaborne oil shrinks by 20% overnight, the cost of shipping becomes second order. 150
Ryan Cummings @weakinstrument.bsky.social · 22/09/20266/end: Banning diesel exports would, in effect, be a small subsidy to farmers and other industrial users of diesel across the country at the expense of New England residents, who would see heating costs skyrocket if not run into acute physical shortages. 815734
Ryan Cummings @weakinstrument.bsky.social · 22/09/20265/n: What's so worrying is that in the Biden Admin, when Russia invaded Ukraine in 2022 and the global diesel market tightened, we were concerned that PADD 1A might actually run out of physical diesel and have to engage in rationing. By all accounts, the situation is even worse now. 2987
Ryan Cummings @weakinstrument.bsky.social · 22/09/20264/n: This matters much more for PADD 1A than anywhere else in the country because in New England, diesel isn't just for industrial uses; *half* of homes in Maine use diesel (No 2. fuel oil) for heating. Over a million people in MA use it for home heating. 310512
Ryan Cummings @weakinstrument.bsky.social · 22/09/20263/n: Because the U.S. exports so much diesel, banning those exports would shrink global supply, raising global prices and therefore the imported price that PADD 1A pays. This also couldn't be happening at a worse time; diesel inventories in PADD 1A are lower than anypoint in the past 10 years. 11009
Ryan Cummings @weakinstrument.bsky.social · 22/09/20262/n: Banning diesel exports would *temporarily* provide some price relief for most of the country, but not for New England. Because pipelines don't run that far north, PADD 1A has to import large amounts of diesel, which means it's competing with a (structurally short diesel) Europe for barrels 313020
Ryan Cummings @weakinstrument.bsky.social · 22/09/20261/n: Because of record-breaking diesel prices, the Trump Admin is reportedly considering a diesel export ban. There is one part of the country that this would squeeze tremendously, risking physical shortages that would prevent people from heating their homes in winter: New England (PADD 1A). 1117970
