Rory Johnston: ‘Ragingly Tight’ Diesel Markets, Skyrocketing Inflation & The Escalating Iran War
Palisades Gold RadioShow Notes
Rory Johnston, founder of Commodity Context and host of the Oil Ground Up podcast, joins Palisades Gold Radio to dissect the current energy crisis. He argues that while the market has avoided outright shortages in the West, the war has created a “balkanized” global oil market. The primary issue is not just crude supply, but a severe crisis in refining capacity, particularly for middle distillates like diesel and jet fuel. Diesel crack spreads have hit unprecedented levels (near $100-$120 a barrel), driven by a combination of the Iran war, Ukrainian attacks on Russian refineries, and Houthi strikes on Saudi infrastructure. This has led to a million to 1.5 million barrels per day loss in diesel supply, with emerging markets like Indonesia feeling the pain of outright shortages first.
Johnston highlights the compounding effect of skyrocketing shipping costs, which have risen tenfold due to the inefficient “dark transit” system in the Strait of Hormuz and attacks on vessels. This has fractured the global market into isolated pockets of oversupply and undersupply, making it expensive to arbitrage regional imbalances. He is skeptical of political fixes, dismissing the Trump-Putin diesel deal as a “drop in the bucket” (roughly 125,000 barrels per day) and warning that a US diesel export ban would be counterproductive, as it would reduce refining incentives and spike global prices. The only durable solutions, he argues, are ending the wars in Ukraine and the Middle East.
Looking ahead, Johnston sees a potential scenario where crude prices fall (even to $60) while diesel remains expensive ($150-$160) due to lingering refining constraints. He notes that the market is still in a deficit of 2-3 million barrels per day, drawing down stockpiles, but believes a resolution to the Iran war could flip crude into oversupply. A key wildcard is China, which could loosen its export quotas and provide critical diesel supply through the winter, as it did in 2022-2023. He also flags that a “Super El Nino” could provide a lucky reprieve by moderating winter demand for heating fuels.

Brett Rentmeester, founder of Windrock Wealth Management, argues that we are entering a “Fourth Turning”—a roughly 100-year crisis cycle in American history, following the American Revolution, Civil War, and Great Depression/WWII. He identifies four major tailwinds that powered the last 40 years of conventional investing (falling inflation, falling interest rates, rising equity multiples, and massive debt accumulation) as now reversing into headwinds. With US debt at $40 trillion, interest payments consuming 28% of tax revenue, and the 10-year Treasury at 5.1%, Rentmeester warns of a “death by a thousand cuts” rather than an outright default—characterized by financial repression, higher inflation, and eroding purchasing power.
Stijn Schmitz welcomes Bob Moriarty to the show. Bob Moriarty is Author, Founder 321 Gold, & Former Marine Fighter Pilot. The discussion centers on escalating Middle East conflicts, particularly the Houthi attacks on Saudi Arabia and the broader geopolitical brinkmanship involving Iran, Israel, and the United States.
Stijn Schmitz welcomes Trader Ferg to the show. Trader Ferg is a Full-time Trader and is the Author of the Trader Ferg Substack. The discussion opens with a vivid illustration of emerging fuel shortages, as Trader Ferg shares images of long queues at his local petrol station in Bali, a symptom of diesel and product tightness spreading across Asia. He argues that governments avoid admitting scarcity, instead running down strategic reserves, but this dynamic sets the stage for a prolonged “big refill” cycle that will keep crude and refined products tight for years. He cautions that markets are complacently expecting a quick resolution, while the reality points to sustained supply constraints.
Stijn Schmitz welcomes Jeff Phillips to the show. Jeff Phillips is a Private Investor and President of Global Market Development. Jeff Phillips sees the current pullback in precious metals and junior miners as a buying opportunity within a longer-term commodity super cycle driven by underinvestment, supply chain concerns, and inflationary currency debasement. He cautions that short-term timing remains uncertain, so maintaining cash and avoiding overleverage is essential. Phillips focuses on junior exploration and development companies, typically entering at $5 to $40 million market caps, and stresses that management quality and share structure matter more than geology alone. He looks for experienced teams with significant insider ownership and long-term shareholders rather than warrant flippers.
