Forward Buying Strategy: What 3 Years of Butter, Cocoa and Sugar Prices Teach About Layered Cover

Layering cut the average budget miss for butter from 24.2% to 11.2%.

It did not make butter cheaper.

That is the result of a backtest we ran on three years of EU butter benchmarks, cocoa bean prices and white sugar. We compared three ways to buy: spot, one annual fix, and layered cover.

In this post you’ll get the full results, the assumptions behind them, and a cover ladder you can copy for your own ingredients.

Plus the rules for when to bend that ladder.

What is a forward buying strategy?

Forward buying is agreeing today on the price of an ingredient you will take delivery of later, through a fixed-price supplier contract or a futures position. A forward buying strategy sets how much of each future period you cover, how far ahead, and when. Its goal is a predictable cost.

It is one tool in a wider plan for managing commodity price risk in food manufacturing.

And it raises one question every buyer asks sooner or later: when to lock in prices?

The honest answer is that nobody knows the best day. So most good strategies stop trying to pick it.

Kendra Rhodes, who leads commodity risk management at General Mills, describes what buyers are up against:

The three ways to buy: spot, annual fix and layered

Almost every food buyer runs some mix of these three. Here is each one in plain terms.

Strategy #1: Spot

You buy each period’s volume at the market price of that period.

Your cost tracks the market exactly. Great when prices fall. Painful when they spike. Your budget is a guess until the invoice arrives.

Strategy #2: The single annual fix

In October, you fix all of next year’s volume at the October price. One forward contract, one decision.

Your budget is exact. But your whole year rides on the price of a single day.

Strategy #3: Layered cover

You buy each quarter’s volume in slices, spread over time.

In our test, every quarter’s need was bought in four 25% tranches: at the start of that quarter and at the start of each of the three quarters before it. That is a rolling four-quarter layer. Each purchase date covers a quarter of the next four quarters.

This is what treasury teams call a layering strategy or layered hedging. Your cost becomes an average of four prices, so one bad buying date can only hurt a quarter of your volume.

The backtest: 3 years of butter, cocoa and sugar

Let me show you.

We took Vesper’s quarter-start prices for three ingredients from January 2023 to October 2026:

• EU butter: the Vesper Price Index (VPI), EXW Europe, in EUR/mt.
• Cocoa: Vesper’s ICE-linked Europe cocoa price, EXW, in EUR/mt.
• White sugar: Vesper’s ICE No.5-linked Europe price, EXW, in EUR/mt.

Then we bought an equal volume every quarter from Q1 2024 to Q4 2026 (12 quarters) under each strategy.

Result #1: Average cost per year

Here is what each strategy paid, per year and on average.

All figures EUR/mt. Source: Vesper quarter-start prices, Jan 2023 to Oct 2026. Backtest is our calculation.

Look at the last column first.

Layering pulled in the extremes. Cocoa’s worst quarter fell from €10,845/mt buying spot to €8,844/mt layered. Its best quarter rose from €2,827/mt to €3,340/mt. You give up some of the lows to avoid some of the highs.

Result #2: Budget miss

Now the number your CFO cares about. How far was the actual cost from the budget rate set the October before?

Budget rates in EUR/mt. A positive miss means you paid more than budget. Source: Vesper quarter-start prices, Jan 2023 to Oct 2026. Our calculation.

You might wonder about the annual fix. In this test it always hits budget, by construction: the budget rate is the price you fixed. Its risk shows up somewhere else, as we’ll see in a minute.

Result #3: What butter looked like quarter by quarter

This chart shows the smoothing in action.

The layered line lags the spot line. It climbs later and falls later.

In 2024 that lag saved money while butter rose from €5,500/mt to €7,700/mt. In 2026 it cost money: layered buyers were still paying €5,975/mt in Q1 2026 when spot was €4,050/mt.

Over the full three years, the two lines nearly cancel out.

What the backtest really shows

Three findings. Each one is worth more than the headline.

Finding #1: Layering made budgets predictable

Layering roughly halved the average budget miss for butter and sugar, and cut it by a third for cocoa.

Here’s why: a rolling layer means part of next year is already bought when you set the budget. In our setup, 6 of next year’s 16 tranches (37.5%) were bought by October, at known prices. The rest were averaged across the year.

So the budget rate and the real cost start much closer together.

That matters for setting a 2027 budget rate. A budget your cost lands near is a budget finance trusts.

Finding #2: Layering did not beat the market

Over three years, compared with buying spot:

• Butter: layered cost €5,766/mt vs €5,669/mt, +1.7%.
• Sugar No.5: layered cost €492.1/mt vs €467.4/mt, +5.3%.
• Cocoa: layered cost €6,195/mt vs €6,325/mt, -2.1%.

Two of three cost a little more. One cost a little less.

That is what averaging does. In a falling market (sugar through late 2023 to early 2026, butter from mid-2025), older tranches drag your cost above spot. In a rising market, they hold it below.

Nor did layering help cocoa in every year. In 2025, the layered cocoa miss (+32.7%) was worse than spot (+24.0%), because tranches bought during the 2024 spike were still being delivered.

If someone sells you a forward buying strategy as a way to pay less, ask for their backtest.

Finding #3: The annual fix was a coin toss

The annual fix produced the best and the worst result in the whole test.

• Cocoa: the October 2023 fix locked 2024 at €3,497/mt, before the spike. Over three years the annual fix averaged €5,000/mt, 20.9% below spot (our calculation). For context, cocoa peaked at €12,007.46/mt on 18 Dec 2024.
• Sugar: the October 2023 fix locked 2024 at €663.98/mt, close to the highest print since October 2023, €712.98/mt on 3 Nov 2023. Over three years the annual fix averaged €524.3/mt, 12.2% above spot.
• Butter: the fix averaged €5,967/mt, about €298/mt more than spot on average.

Same rule, same month, opposite results. That is luck, and you can’t repeat luck as a strategy.

The annual fix hits budget every time. But if you fix at a peak, your competitors who buy later pay less than you for a full year. That is the hidden risk of a perfect budget.

How to build a cover ladder

A cover ladder is a written rule for how much of each future quarter you have bought by now. It takes the timing decision out of the moment.

Here is how to build one in four steps.

Step #1: Pick your horizon and tranche size

Start with four quarters and 25% tranches, as in the backtest.

Each quarter, you buy 25% of the volume for this quarter and each of the next three. After a year of doing this, you reach a steady state where the ladder looks like this:

The current quarter is fully covered. The next quarter is 75% covered, the one after 50%, the third 25%.

That 75/50/25 shape is the default this post uses. Shorter shelf life or shakier demand means a shorter ladder.

Step #2: Set cover bands by ingredient type

One ladder does not fit every ingredient. Two questions decide the shape: can you store it, and is there a futures market?

Example bands for illustration. Set your own from demand certainty, shelf life and storage cost.

The band is the point. You get a floor and a ceiling for each quarter, and you move inside it.

Step #3: Buy on a calendar

Put the tranche dates in the calendar for the year. First week of each quarter, for example.

The calendar is what makes it a ladder. If you only buy when it “feels right”, you are back to timing the market with extra steps.

Price each tranche off the forward curve for its delivery month. Vesper shows today’s forward curves next to spot, so you can see what each tranche will cost before you commit.

Step #4: Tilt the ladder with a forecast

The calendar sets when you buy. A forecast can set how much, within your band.

The rule: when the Vesper forecast sits well below the futures strip, under-cover the far quarters. When it sits above, fill them on schedule or at the top of the band.

Take EU skimmed milk powder.

• EU SMP spot was €3,500/mt (VPI, EXW) on 7 Oct 2026.
• The 2027 EEX SMP futures averaged €3,471/mt over Mar, Jun, Sep and Oct 2027, the months where both a futures contract and a Vesper forecast point existed.
• The Vesper forecast averaged €3,036/mt over the same months.

The futures strip sits 14.3% above the forecast (our calculation from the Vesper figures). A buyer running 75/50/25 might hold the next quarter at 75%, but drop the second and third quarters toward the bottom of their bands. That leaves room to buy later if the forecast is right.

Butter points the other way. The 2027 EEX butter futures average of €4,366/mt sits 4.2% below the Vesper forecast average of €4,556/mt. Spot was €3,790/mt on 7 Oct 2026. No case for under-covering there.

The full picture for EU dairy, including stocks and our outlook, is in the EU dairy Q4 2026 market outlook.

You can see how the forecast is built on the Vesper forecasts page.

Layering without futures: WPC80 and cocoa butter

Most food ingredients have no liquid futures market. WPC80 has none in Vesper. Neither does cocoa butter.

You can still layer. You just layer with suppliers.

Option #1: Supplier forward contracts in tranches

Split your annual volume into quarterly or monthly contracts and fix them at different dates. Same ladder, same calendar. Your supplier takes the other side of the trade.

This matters most where prices swing hardest. Instant WPC80 in Europe (VPI, EXW) ranged from €12,300/mt (15 Oct 2025) to €27,900/mt (24 Jun 2026), and stood at €21,000/mt on 7 Oct 2026. Fixing a whole year in one go in that market is a big bet.

Option #2: Index-linked tranches

Agree a formula price tied to a published benchmark, then fix the index for some tranches and float it for others.

Cocoa butter shows why this helps. The West-EU cocoa butter price peaked at €42,540.75/mt on 13 Dec 2024 and stood at €8,012.25/mt on 13 Oct 2026. A buyer who fixed a full year at the peak paid a premium for a year. A buyer with floating, indexed tranches followed the market down.

How to write the clause, including lags and base periods, is in our guide to index-linked pricing clauses.

If you buy for chocolate production, the chocolate Q4 2026 market outlook covers cocoa beans and butter together.

The limits: where a ladder breaks

Layering is a sound default. It is not a law. Four things bend it.

Limit #1: Shelf life and storage

A forward contract for delivery is only useful if you can take the goods when they arrive. Fresh eggs, cream or short-life dairy cap how early you can buy physical volume.

The fix: fix the price early, take delivery late. Or hedge financially with futures where they exist, and buy the physical product close to use.

Limit #2: Crop years

Cocoa and sugar move with harvests. A tranche that straddles a new crop may price a very different supply picture.

Line your ladder up with crop-year timing where you can, and expect bigger moves around harvest reports.

Limit #3: Minimum lots

Futures trade in fixed lot sizes, and suppliers set minimum order quantities. If one quarter’s volume is smaller than a lot, a 25% tranche may not exist.

Use bigger tranches less often (two 50% tranches, say), or pool volume across sites.

Limit #4: Counterparty risk

A forward contract is only as good as the party on the other side.

When cocoa butter fell from €42,540.75/mt to €8,012.25/mt, anyone holding a fixed contract near the peak had every reason to renegotiate. Suppliers face the same pressure when the market runs away from a low fixed price. Layering spreads that risk across dates and, ideally, across suppliers.

Gert-Jan van den Akker lived through this at Cargill, when freight rates collapsed and counterparties pushed for blanket renegotiations:

Bottom line: a ladder handles timing risk well. It does nothing about volume, storage or a supplier who walks away. Plan for those separately.

Next steps

1. Pull quarterly prices for your top three ingredients and rerun this backtest with your own budget rates.
2. Write down a cover band for each ingredient, using the table above as a start.
3. Set tranche dates for the next four quarters.
4. Review the bands against the forecast once a quarter. See how buyers do this with Vesper for market timing.

Then pick the instrument for each band: our guide on which hedging tool fits which ingredient covers futures, supplier contracts and index clauses side by side.
