The government can only regulate prices for certain foodstuffs and that is only the upper limit or highest price, and the market will always determine the overall price, the rarer the goods are found and the demand is high, the market will automatically raise prices, and you will know that in countries with high levels of corruption and even their officials are involved in determining prices in the market because they are trying to make a profit.
What the government can do is only monitor prices in the market and when they have exceeded the normal limit, the government will act, but often they fail to carry out this function so that the prices of basic commodities continue to rise and sometimes they are rarely available on the market.
