First Minister John Swinney intends to legally cap the price of up to 50 essential supermarket items in Scotland using devolved public health powers. The strategy aims to shield hard-pressed households from grocery inflation by fixing prices on staple goods like bread, milk, and eggs. However, the policy is already unraveling because it relies on a flawed legal mechanism that conflicts with UK internal market laws, lacks a realistic mechanism to protect local farmers, and faces stiff resistance from the very retailers required to implement it. Instead of lowering grocery bills, the plan will likely result in a prolonged, expensive courtroom battle with Westminster.
To understand why this policy is hitting a wall, one must look at the legal architecture of devolution. Swinney is attempting a tactical maneuver by framing food prices as a matter of public health rather than economics. Because economic regulation and trade are largely reserved to Westminster, Holyrood cannot simply dictate the retail price of groceries. But by arguing that high food prices are actively harming the nation's nutrition and well-being, the Scottish National Party wants to use Scotland's independent public health powers as a backdoor to the supermarket till.
The Ghost of Minimum Unit Pricing
The administration points to the 2018 introduction of Minimum Unit Pricing for alcohol as proof that this strategy can work. It is a poor historical comparison. Setting a floor price to discourage consumption of a harmful substance is fundamentally different from setting a ceiling price to artificially lower the cost of essential nutrition.
When Scotland altered alcohol pricing, it faced a six-year legal battle led by the Scotch Whisky Association. Food retailers and global supply chains possess vastly deeper pockets and far less patience for localized price controls. Furthermore, the post-Brexit legislative landscape features a major hurdle that did not exist when minimum alcohol pricing was first drafted: the UK Internal Market Act.
Introduced to ensure a level playing field across all four nations of the UK, this Act explicitly prevents one region from creating regulations that restrict the free flow of goods from another. If a supermarket chain buys milk in northern England and sells it in southern Scotland, a legally mandated Scottish price cap disrupts that internal market. Senior UK government sources have already labeled the plan undeliverable, predicting millions of pounds in wasted legal fees.
The Myth of the Burdenless Cap
Swinney recently claimed that his administration would develop mechanisms to ensure supermarkets do not pass the financial losses of a price cap down to farmers and food producers. This assertion ignores the harsh reality of corporate grocery economics.
Supermarkets operate on notoriously thin profit margins, often between 1% and 3%. When a government legally forces a retailer to lower the price of a core commodity, the retailer has exactly three choices to balance its books:
- Absorbing the loss and angering shareholders.
- Raising the prices of uncapped, non-essential goods.
- Squeezing the supply chain by demanding lower costs from processors and agricultural producers.
The idea that a devolved administration can police the internal contract negotiations between multi-billion-pound supermarket chains and their suppliers is wishful thinking. Representatives from the Scottish Farmer and various agricultural unions have already expressed severe anxiety. If supermarkets cannot pass the costs to consumers or farmers, they may simply stop stocking the capped items altogether, triggering artificial shortages of basic food items.
The Voluntary Retreat
Signs of retreat are already visible. Just days after asserting that hard legislation would be firmly in place within the new government's first 100 days, Swinney pivotally opened the door to a voluntary scheme. He suggested that negotiating directly with supermarkets to voluntarily limit prices would yield quicker results.
The sudden shift reveals a clear acknowledgment of the legal fragility of the mandatory policy. Yet even a voluntary agreement is fraught with danger. The Scottish Retail Consortium immediately warned that any structured, voluntary pricing arrangement among major competitors risks violating strict UK competition laws regarding collusion and price-fixing. Government-sponsored price coordination is still price coordination.
Economic Precedent and the 1970s Trap
History is unkind to price controls on food. When governments try to artificially suppress prices without addressing underlying supply costs, the market reacts predictably. Retailers shift their focus toward premium, unregulated goods, leaving the basic, capped varieties underfunded and scarce.
Smaller independent grocers and corner shops suffer the most. While massive supermarket chains might survive by cross-subsidizing losses across thousands of product lines, local independent retailers cannot. The Scottish Grocers’ Federation has warned that forcing price ceilings onto a sector already struggling with rising business rates and energy costs could push smaller shops into bankruptcy.
Instead of a bold anti-poverty measure, the food price cap has the hallmarks of a political lightning rod. It is designed to spark a high-profile constitutional row with Westminster, allowing Holyrood to blame the UK government when the policy inevitably stalls in court. Scottish shoppers, currently facing very real financial pressures at the checkout counter, deserve structural economic solutions rather than a legally flawed policy that puts money into the pockets of lawyers instead of working families.
