Cheap Depends on How Long You Can Keep It
 |
A low price sounds like a fact about supply and demand. Often it is a fact about the calendar.
For anything that has to be stored, today's price is not answering "is there enough of this?" It is answering "is there enough of this right now, in the place it is needed, in a container that exists?" Those are very different questions, and which one a price is answering depends almost entirely on how easily the thing can be kept.

Storage Is What Connects Today to Next Year
Start with the extreme cases, because they make the principle visible.
Something that stores perfectly and costs nothing to hold would have essentially one price. Any gap between now and later would be closed by someone buying, holding and delivering. The current price would carry the market's full view of the future, because the future would be reachable from the present.
Something that cannot be stored at all has no such link. Each moment stands alone. The price reflects supply and demand in that instant and nothing else, and it can move to extremes — including below zero, when producing is easier than stopping and consuming is scarce. Electricity behaves this way, which is why its prices look unhinged next to those of physical goods. They are not unhinged. They are unbuffered.
Everything real sits between these poles, and its position on that line determines what its price actually tells you.
The cost of storage is the whole variable: the tank, the warehouse, the refrigeration, the insurance, the spoilage, the interest on the money tied up. The cheaper it is to hold something, the more today's price is about the future. The more expensive it is to hold, the more today's price is about today.

The Forward Curve Is a Storage Report
There is a clean way to read this from public data, and it does not require a view on anything.
If later delivery costs more than immediate delivery, the market is paying you to hold inventory — covering storage and financing. That is the normal state for a storable good with adequate supply. It says the buffer is comfortable.
If immediate delivery costs more than later delivery, the market is doing the opposite: paying a premium for having the thing now rather than later. That is a shortage signal, and it usually means inventories are thin or physically hard to move to where they are wanted.
The relationship between the two prices is therefore a report on the buffer. It is published continuously, it requires no forecast, and it frequently contradicts the headline.
It is also one of the few places where a market states its own conditions out loud. Most prices carry assumptions with dates attached and print none of them. A forward curve is the exception: it is a price with its timing written next to it.
A commodity can be at a multi-year low price and simultaneously signalling scarcity, if the near-term price is above the far-term one. The low number is describing the season. The shape is describing the tank.

Seasonal Goods Have Two Prices Wearing One Number
Anything with a strongly seasonal demand pattern makes this vivid.
Natural gas is the standard example. Consumption is concentrated in heating and cooling seasons. Production is much steadier. So the entire system depends on injecting into storage during quiet months and withdrawing during heavy ones — and the price in a quiet month is, in large part, a statement about how full the tanks are before the demand arrives.
A mild spring with comfortable inventories produces a low price. That low price is not evidence that supply is abundant in any durable sense. It is evidence that demand has not arrived yet and the buffer has not been tested.
The awkward part is that the buffer's adequacy cannot be judged from the price. It has to be judged against the coming season, the size of the storage capacity, and how quickly the material can be moved once it is needed. Those are physical facts. The price knows about them only after they bind.
And when the buffer does bind, the effect does not arrive everywhere at once. It moves outward through contracts, tariffs and processing at a speed set by the plumbing rather than by the headline, which is why a dramatic move in a wholesale market and a quiet month in a household budget can be the same event seen at different distances.

What This Looks Like From Korea
Korea makes the storage question unusually concrete, because the country's physical position removes most of the flexibility other markets take for granted.
There are no import pipelines. Natural gas arrives entirely as LNG, by ship, into terminals with a finite number of tanks. That means the storage buffer is not an abstraction that expands when prices are attractive. It is a countable number of vessels and a berth schedule. And regasification and distribution are handled through a public wholesale structure rather than by each buyer independently.
The consequence is that the spot price of gas somewhere else is not what a Korean household pays, and the reason is not only the usual contract lag.
Here the more interesting mechanism is what happens when import costs rise faster than tariffs are allowed to. Domestic city-gas rates are set administratively under a cost-recovery framework, and when the authorities restrain increases for cost-of-living reasons, the gap does not disappear. It is recorded as a receivable — an amount owed to the supplier and recovered later.
The scale of that accumulation is public and it is large. Residential city-gas receivables reported at roughly 1.77 trillion won at the end of 2021 had reached about 13.75 trillion won by the middle of 2024, after a series of increases that still did not reach full cost.
Read that as a storage statement and it is striking. The country could not store the gas cheaply, so it stored the cost instead. The physical commodity was consumed; the price difference was moved onto a balance sheet and carried forward.
Which is the general form of the thing. When the buffer cannot be physical, it becomes financial — and a financial buffer, unlike a tank, does not empty. It compounds, and it is recovered later from the same households, at a time chosen by someone else.

What This Page Used to Say
This URL previously held a post that combined three unrelated subjects, and most of it has been removed.
Two removals matter.
The first is a set of instructions: an allocation to money-market funds at a stated yield, a recommendation to average into unspecified quality names, standing directions about borrowing and leverage, a suggestion that certain sector exposures were "worth watching," and a stated point at which readers should reduce risk. That is advice, and it does not belong here.
The second is more serious. The post reported on an armed conflict — naming the states involved, quoting a head of government on removing a central bank official, and itemising damage to energy infrastructure down to a dollar figure, a facility count and a percentage of one country's export capacity. Those figures may be accurately sourced. They are still not this blog's to relay, for the same reason as before: which states are damaging what, and what any government intends by it, requires a competence this publication does not have and cannot acquire by citing a newswire.
What survives is the observation the original made and then buried:
The current price reflects mild spring weather and comfortable inventories. It does not reflect what happens when the season turns.
That is a statement about storage, and it is true every year, in every storable market, with no conflict required.

Where This Stops Being Useful
The curve is not a forecast. A market paying a premium for immediate delivery is describing present tightness, not predicting a price. These signals reverse.
Storage economics do not tell you direction. They tell you how much information the current price contains and how violently it can move. A thin buffer means larger swings, in either direction.
And this is not an argument that seasonal lows are bargains. A low price in a quiet month is normal, expected, and already understood by everyone trading it — the same reason an announced diversification is an input rather than an outcome. Knowing why a price is low is different from knowing it will rise.

Where You Are Standing
Ask how long the thing can be kept before asking whether it is cheap. A price for something that stores badly is a snapshot. A price for something that stores well is a summary of expectations. The word "cheap" means different things in the two cases.
Read the shape, not just the level. Where forward prices are published, the relationship between near and far delivery is a free, continuous report on the buffer — and it regularly says something different from the headline number, in the same way that inventory data is read in opposite directions by two different kinds of buyer.
And look for the buffer that is not a tank. When a price is being held below cost by policy or contract, the difference is accumulating somewhere. It is usually disclosed, it is usually large, and it is usually recovered later — which makes it a cost that reaches the invoice on a schedule of its own, rather than a cost that was avoided.

A Closing Note
There is a habit of treating a low commodity price as good news and a high one as bad, as though the number were a verdict on abundance.
More often it is a verdict on timing, and on whether anyone has anywhere to put the stuff. A full tank in a mild month and an empty one in a hot week can produce the same annual supply and completely different prices, and only one of those situations is comfortable.
The number tells you what it costs today. How long you can keep it tells you whether today's number means anything at all.
