Karl Miller’s latest private assessment, dated September 16 and titled “Judgment Day Has Arrived,” makes a single governing claim about diesel, jet fuel, and kerosene: physical demand is now outrunning promptly deliverable supply. Not the price of the barrel — the delivery of it. In Miller’s framing the market has crossed from a pricing problem, which money solves, to a deliverability problem, which money alone does not. The next phase, he argues, forces buyers to compete not just for fuel but for delivery capacity and for the cash to fund both at once.
He is describing something the market has already begun to confirm… US retail diesel crossed $6.00 a gallon on September 11, the first time on record, ten days after setting its prior all-time high. The ULSD crack spread — the margin between diesel and crude — hit an intraday record above $108 a barrel on September 3, a level never before sustained, which tells you the scarcity is in the product, not the barrel. Distillate inventories fell to roughly 103 million barrels in late August, the lowest for that point in the calendar since 1951, and the EIA expects them to stay below 100 million through much of 2027. Miller wrote his brief into a market that is already validating its premise.
The governing condition
The spine of the assessment is deliberately simple. Take a recurring shortfall between what a market consumes and what can actually be delivered to it. Inventory and diverted cargoes can bridge that gap for a while. They cannot sustain it indefinitely. Once usable stocks are drawn down, the adjustment arrives as some combination of higher replacement cost, tighter allocation, and reduced activity — and it lands first on whichever buyer, terminal, or airport cannot secure its next delivery on time. Miller’s phrase for the resolution is stark: supply must recover, or consumption must fall. There is no third option once the buffers are gone.
To size the thing, he runs a central diesel stress case — and here it is essential to be precise about what kind of number this is, because Miller himself is. He assumes a 1.6 million-barrel-a-day export disruption met by 50 percent replacement, leaving a residual gap of 0.8 mb/d. Held constant, that residual would demand about 72 million barrels of stock draw or demand destruction over 90 days, and 144 million over 180. These are explicitly illustrative sensitivities, not a measured global deficit — he flags repeatedly that product-level deficit magnitudes remain uncertain and that the figures are scenario mechanics rather than forecasts. The value is in the method, not the decimal.
And the method maps onto the real shocks cleanly enough. The IEA has identified three disruptions compounding at once: the Hormuz conflict removing on the order of an eighth of global supply, Russian diesel-export bans after drone strikes disabled roughly a quarter of its refining capacity, and winter distillate demand arriving into depleted tanks. Russia — historically the world’s second-largest diesel exporter — banned exports outright on July 9 to keep fuel for its military. Miller’s 1.6 mb/d is an assumption; the machinery pulling barrels off the water is not.
Inventory as a countdown, not a cushion
The sharpest operational move in the brief is to demote the national inventory number that dominates the headlines. A country-level buffer, Miller argues, tells you almost nothing about whether a specific business keeps running. What matters is site-level endurance: usable stock — excluding tank bottoms, unqualified material, and volumes already committed to other buyers — divided by the net daily draw. A terminal with a fixed usable volume and a widening deficit is on a clock, and a replacement cargo that arrives four days after the clock runs out may as well not have sailed. The same logic scales down to a hospital’s or data center’s backup generators, where a tank that reads “full” is really a countdown measured in days against a known burn rate.
This is why his diagnosis is that the shortage will be local and uneven long before it is general. A national statistic can look adequate while individual nodes fail, because fuel that exists in the wrong place, in the wrong grade, or under someone else’s contract does not cover a missed delivery. This broader point is illustrated in the photos at the top of this article.
Credit decides who gets the cargo
Miller’s second key insight is financial. In a market where prices are high and delivery cycles are long, the buyer has to fund both simultaneously — pay up for the barrel and carry it for the extra days it spends in transit. He illustrates with a delivered-cost stack that runs, in his tight-to-acute range, from roughly $200 to nearly $300 a barrel once location premium, ocean freight, terminal handling, inland delivery, and financing are added on top of the benchmark — the equivalent of something like $4.80 to $6.90 a gallon before tax. Again, these are illustrative route economics, not quotes. But note that the market has already printed the middle of that range: $6 diesel is here, and California retail has been reported above $9.
The consequence he draws is the one worth keeping: credit becomes a supply constraint. A buyer can be perfectly solvent on annual earnings and still lack the working capital to prepay a larger cargo, meet collateral calls, and carry slower-moving inventory all at the same time. When that happens, the fuel goes to whoever can fund it, not whoever needs it most. Financially weaker importers can lose access before larger economies feel the squeeze at all.
Aviation and the airport problem
Jet A and Jet A-1 get their own treatment, because aviation has the least room to improvise. Qualified fuel has to be at the airport, in the hydrant, before the aircraft departs; a refinery barrel somewhere else is worthless to a delayed flight. Airlines are left to choose among buying costlier replacement fuel, tankering extra where it is operationally feasible, reworking schedules, or cancelling. Miller’s illustrative math — a $20-a-barrel step adding $60 million over 30 days for a 100,000-barrel-a-day buyer — is less important than the structural point: hedging can change what a carrier pays, but it cannot conjure a delivery that the airport cannot physically make. He is also careful to note that jet fuel and kerosene are the same cut of the barrel, so the aviation volume must not be double-counted as additional kerosene demand — a discipline that a lot of looser analysis ignores.
Where it bites first, and how it ends
The geography of risk, in his ranking, runs through the weakest local links: import-dependent Northwest Europe and inland markets facing winter demand on top of freight fuel; the US Gulf Coast, whose refining and export weight makes any local outage a global event; import-dependent emerging markets where foreign exchange and cargo finance can fail before physical stocks do; and airports with concentrated, hard-to-substitute supply. The common thread is that substitution is hardest exactly where the stakes are highest.
On duration, Miller offers no normalization date, and insists none can be honestly given. His planning horizon is 90 to 180 days with contingency held into 2027. The recovery point he stresses is one that calendar-watchers routinely miss: ending the shortage requires not a daily balance but a sustained surplus, because supply first has to stop the draw and then rebuild the usable buffer while still covering consumption. At a half-million-barrel-a-day surplus, rebuilding 30 million barrels of cover takes two months — and that clock only starts after supply overtakes demand. A market that merely returns to breakeven stays fragile.
The verdict
Strip the brief to its load-bearing claim and it does not merely hold up against the tape — the tape is racing to catch up to it. This is, by every current metric, a middle-distillate physical-supply crisis: record crack spreads above $108 confirm a refining and yield failure rather than a crude shortage, inventories sit at their lowest level in seven decades heading into heating season, refineries are already running at 98 percent and still cannot make enough of the middle of the barrel, and traders and the IEA alike are warning the tightness runs clear through winter and into 2027. Miller called the nature of the danger correctly and early: this is about deliverability — the next cargo, the qualified grade, the funded position — not headline price, and that lens is sharper than nearly all of the commentary still treating a structural break as a passing spike. He wrote “Judgment Day Has Arrived” into a market that promptly broke $6 diesel for the first time in history, printed the highest distillate margins ever recorded, and watched a quarter of Russia’s refining capacity and an eighth of global supply go offline at once. The banner is not hyperbole. It is a description.
One distinction has to be kept, and it is the one that makes the brief stronger rather than weaker: the quantified apparatus is a scenario toolkit, not a set of measured deficits. The 1.6 mb/d disruption, the cost ladders, the barrel counts are illustrative sensitivities — Miller says so himself — and their power is in the method, not the decimal: the residual-gap arithmetic, the site-level endurance countdown, the credit gate. Insist on that and the framework is unassailable, because you are handing a reader a way to run the numbers rather than a number to argue with. And the one development that could ease the price — softening freight and contracting manufacturing — is no refutation at all. It is the second of the two exits Miller named. Either supply recovers or consumption falls, and consumption falling is not the crisis being escaped. It is the crisis arriving.
