Signal Radar: A better deal can make supply less reliable

Signal Radar Weekly | 31 August – 6 September 2026

A lower price or more time to pay looks like a win. But someone else has to carry the cost. If that leaves a supplier less willing or able to deliver, the buyer can end up paying for the saving elsewhere.

This week’s evidence points to the moments when that can happen: a contract comes up for renewal, a carrier decides how much extra freight to accept, or a supplier is asked to wait longer for payment.

The useful warning may come before a missed delivery. A supplier can still be delivering under today’s terms while deciding to offer less under tomorrow’s. That makes the next negotiation a chance to spot a problem before it reaches production or customers.

This is not a reason to stop negotiating hard. It is a reason to ask one more question before calling a deal an improvement: what can the supplier still deliver on these terms?

The Bigger Pattern

Earlier editions explored why spare capacity does not always mean easy access. Providers choose which customers to serve. Contracts decide who pays when things go wrong. Last week, the focus included the financial health of the companies a buyer relies on.

This week connects those ideas to decisions buyers make themselves. A good relationship cannot make an expensive delivery route cheap to run. A trader may carry a loss under one contract and try to pass it on at renewal. Paying later keeps cash in the buyer’s account while leaving the supplier waiting for it.

That adds a practical step to supply chain resilience: check what happens when the current arrangement ends or changes. Today’s service tells you what works today. It does not settle what a supplier will offer at the next renewal.

The advantage comes from spotting that difference early. There is more room to compare terms, find another supplier or change a freight arrangement before the promised supply is reduced.

What Changed

The train journey is only part of the freight bill. Schneider says expensive third-party collection and delivery limited the extra business it wanted to take on using rail and trucks together. The report also says local trucking costs rose and waits at terminals grew longer, although it does not measure how much those waits contributed.

The lesson is specific: a good rail price does not guarantee a good price for the whole journey. Promising more rail volume may achieve little if the truck movements at either end remain too expensive. The carrier’s willingness to take the extra freight matters as much as the quote.

The next contract could pass the loss to the producer. Reuters reports deeper cobalt discounts than in early August. Traders have absorbed most of the pressure so far. Indonesian producers warn that contract changes in the fourth quarter could reduce their margins. Some market information is disputed, and no production cut has been established.

The point to examine is the renewal date. Supply continuing now does not show how much a producer will agree to supply if new terms leave it carrying more of the loss. Separately, AGF is considering ammonia cuts because of costs and weaker demand. That is another decision still to be made, not production already lost.

Paying later moves the cash burden to the supplier. The National Association of Credit Management reports customers taking longer to pay, either to keep cash or because their own customers have not paid them. Its overall index weakened, but a measure of credit problems improved.

Separately, the Logistics Managers’ Index reports rising inventory costs despite more warehouse space becoming available. These are different surveys; they do not show that longer payment times caused supplier failures. They do underline why keeping cash longer and reducing the cost of doing business need to be assessed separately.

Why It Matters

Start with the next important agreement, especially where replacing the supplier would take time.

For materials, ask how much the supplier will deliver after renewal and on what dates. Compare that answer with the alternatives before accepting new terms. Paying more can be worthwhile if it secures supply you need. A supplier asking for a higher margin is not, by itself, a reason to agree.

For freight, price the whole journey. Compare buying rail and truck services together, buying them separately and keeping the freight on the road. If a carrier wants more volume promised in advance, establish what that promise improves. Otherwise, you could tie yourself to the service without fixing the expensive part.

For payment terms, separate the cash kept in the bank from any ongoing savings. Then check for costs coming back through higher prices, extra charges or poorer delivery terms. Finance and procurement need to make that assessment together.

The same approach will not suit every supplier. Some can comfortably wait longer for payment or accept lower margins; others cannot. Focus the supply chain risk review on suppliers that are hard to replace and deals that are about to change. Spend money or give up flexibility only when there is a clear benefit for delivery, cost or service.

Signal Strength

There is enough evidence to take this seriously, but not enough to call it a broad fall in supply.

Schneider has already limited the growth it wants because part of the journey costs too much. Customers are taking longer to pay, but the reports do not show that this has caused delivery failures. The cobalt and ammonia production decisions are still open. The credit report also contained signs of improvement.

Together, these signals add weight to the idea that commercial terms can change what gets supplied. Rising means the evidence for this explanation is getting stronger. It does not mean shortages are certain or already increasing.

Current assessment: Medium
Direction: Rising

Questions To Ask This Week

• Logistics: Does the planned move to rail still save money once collection and delivery are included?
• Procurement: Which supplier could offer less at the next renewal, and what alternative could we arrange beforehand?
• Planning & Inventory: What change in promised quantities or delivery dates would justify buying extra stock?
• Commercial: Which customer promises depend on supply we have not yet agreed for the next contract period?
• Finance: If we pay later, how much cash do we keep—and what extra costs might we incur?
• Operations: If we offer a supplier better terms, exactly what delivery improvement do we get, and will it arrive in time?

What We’re Watching Next

The next test is a change in what suppliers agree to deliver.

For cobalt, fourth-quarter contracts offering less material or prompting a production review would strengthen the concern. Agreements that maintain supply would reduce it. At AGF, a decision to cut ammonia production would carry more weight than continued discussion of cuts.

In freight, more carriers turning down extra rail-and-truck business because of collection and delivery costs would show a wider problem. Complete journeys offered at worthwhile prices would point the other way.

For payment terms, look for a clear link between the change and new charges, tighter credit or reduced deliveries. If a supplier maintains service without extra costs, the longer terms may work well.

Those are reasons to change a decision. Another warning about rising costs, on its own, is not.
