Who really sets the price of food?

Ask a shopper who sets food prices and they will say the supermarket. Ask an economist and they will say the market. Ask a farmer and you will get a longer, more accurate answer: a chain of decisions made far from the farm gate, many of them by governments.

Start with the obvious lever: subsidy. The EU's Common Agricultural Policy, the US farm bill, India's minimum support prices — these programmes put a floor under some farm incomes, and that floor changes what gets planted, in what volume, and therefore what everything sells for. Support is real money in farming families' pockets, and in bad years it is the difference between continuing and not. But it also means production decisions follow policy as much as demand, and when policy shifts — a payment redefined, a scheme retired — the price signal a farmer spent a decade building a business around can move overnight.

Then there are the sharper instruments. Export bans: India halted wheat exports in 2022 and rice exports in 2023, moves aimed at domestic food security that repriced grain worldwide within days. Argentina has repeatedly taxed and capped beef exports to hold down local prices — and its producers responded by shrinking the herd. Tariffs and quotas reroute entire trade flows; a signature on a trade deal can open or close a market of fifty million people to your lamb. None of these decisions are made by anyone who will be at your saleyard, yet they can move your cheque more than anything you do in the paddock that year.

It is worth being fair about motive. Governments intervene because food is political in a way software is not: no government survives bread riots, so every government manages food prices — some with floors to protect producers, some with caps and bans to protect consumers, most with an inconsistent mixture of both. The point is not that intervention is evil. The point is that it is enormous, permanent, and mostly invisible to the people it lands on.

What can a farmer actually do with this? Three things. First, read policy the way you read weather — as a force you cannot control but can plan around. Know which of your enterprises stands on a policy floor and what happens if it is lowered. Second, diversify your exposure: direct sales, mixed enterprises and multiple markets are hedges against a single stroke of a pen. Third, show up. Submissions, industry bodies, local members — policy is written by whoever is in the room, and farming is chronically under-represented in it relative to how hard policy lands on farming.

Price is not an act of God. It is partly an act of parliament. The more clearly farmers see that, the better their odds of building businesses that survive it.
