The idea of governments controlling the prices of basic groceries is politically attractive during periods of high inflation because it gives the impression of immediate action against rising living costs.
The Scottish National Party and politicians elsewhere in Europe have periodically discussed versions of price intervention on staple goods such as bread, milk, pasta, eggs or vegetables.
But while price controls can sometimes provide short-term relief, economists generally argue they become increasingly difficult to sustain over time and often create unintended consequences.
How Grocery Price Controls Would Work
The basic idea is simple.
Government would identify perhaps 30–50 “essential” products and either:
cap the maximum retail price
limit annual price increases
or subsidise retailers to keep prices low
The policy aim would be to protect households from food inflation, particularly lower-income families.
In theory it sounds straightforward:
supermarkets cannot charge above the cap
shoppers get cheaper essentials
inflation pressure eases
But in practice the problems begin almost immediately.
The Main Problem: Costs Still Rise
Retailers and suppliers still face real-world costs including:
energy
transport
wages
packaging
imports
fuel
farming inputs
storage
If government caps prices below the true cost increases, somebody must absorb the loss.
Usually this falls on:
supermarkets
food manufacturers
farmers
or taxpayers through subsidies
If losses become too large, suppliers may:
reduce production
withdraw products
cut quality
shrink package sizes
or stop stocking certain goods altogether
This is why price controls often lead to shortages over time.
The “Empty Shelf” Risk
One of the classic economic consequences of strict price controls is shortages.
If a supermarket can only sell butter for £2 but it costs £2.40 to source and distribute, there is little incentive to keep supplying large quantities.
The result can be:
rationing
reduced choice
lower stock levels
or empty shelves
Economists often summarise this bluntly:
“Price controls do not remove scarcity — they hide it.”
Has It Ever Worked?
The answer is: sometimes temporarily, but rarely as a long-term solution.
France
France recently experimented with anti-inflation agreements where supermarkets voluntarily held down prices on selected products.
This had some limited short-term political success, but it relied heavily on voluntary cooperation rather than strict legal enforcement. It also occurred alongside broader government support measures.
Even then, critics argued supermarkets compensated by:
raising prices elsewhere
reducing promotions
or shrinking product sizes.
Hungary
Hungary imposed mandatory price caps on certain food items during the inflation surge of the early 2020s.
Initially this reduced prices on targeted goods, but reports later showed:
shortages
purchase limits
distortions in supply
and higher prices on non-controlled products
Eventually many controls were removed because the wider economic side effects became too severe.
Venezuela
The extreme example is Venezuela, where extensive price controls contributed to chronic shortages and black markets during the country’s economic collapse.
While Scotland or the UK would never reach that scale of dysfunction from limited grocery caps, economists often cite Venezuela as a warning about what happens when governments try to suppress market prices for too long while underlying costs continue rising.
Could Scotland Actually Do It?
There is also a constitutional problem.
Food pricing regulation largely sits within UK-wide competition and consumer law rather than fully devolved Scottish powers.
That means the Scottish Government might struggle legally to impose hard nationwide supermarket price caps without cooperation from UK Government.
Even if Scotland attempted its own scheme, large chains such as:
Tesco
J Sainsbury
Asda
Morrisons
Coop
operate UK-wide supply systems, making Scottish-only controls operationally difficult.
Supermarkets Might Simply Shift Costs Elsewhere
One likely outcome would be “cross-subsidisation.”
If 50 products are artificially cheap, retailers may recover profits by increasing prices on:
branded goods
convenience foods
household products
toiletries
snacks
prepared meals
So while headline staple prices fall, overall shopping bills may not reduce as much as expected.
Farmers Could Be Hit Hard
Another political danger is pressure on farmers and food producers.
Supermarkets are powerful negotiators. If they are forced to sell cheaply, they may squeeze suppliers harder to protect margins.
That could particularly affect:
dairy farmers
meat producers
vegetable growers
smaller Scottish food businesses
Over time this might actually weaken domestic food production.
Why Governments Still Like the Idea
Despite the risks, price controls remain politically attractive because they are highly visible.
Governments can say:
“We forced down milk prices.”
“We capped bread costs.”
“We protected families.”
That message can resonate strongly during cost-of-living crises.
But economists generally argue that inflation caused by:
energy shocks
oil prices
supply chain disruption
currency weakness
labour shortages
cannot ultimately be solved simply by ordering supermarkets to charge less.
The Most Likely Outcome
If Scotland or the UK introduced limited grocery price controls, the most likely outcome would probably be:
Short-term
some visible reduction in selected prices
political popularity initially
pressure relief for households
Medium-term
supermarkets compensating elsewhere
reduced product ranges
possible supplier tensions
pressure for government subsidies
Long-term
either the scheme is quietly watered down
or taxpayers end up funding it indirectly
That is why most countries that have experimented with price controls use them only temporarily during crises rather than as a permanent economic system.
