Never did God give man such a sunny day that the authorities couldn’t make it rain. As near as we can tell, nature favored Argentina as she did few other places. She caused the Andes to rise up and then over millions of years let their hillsides wash downriver to be deposited in a vast, flat, well-watered plain, with topsoil so thick farmers can abuse it for generations.

On the edge of this fertile farmland, and in the middle of one of the biggest booms in farm prices in history, the politicians in Buenos Aires have achieved what might have seemed nearly impossible – they have created a crisis in the agricultural sector. “Day 20. The strike continues: farmers reject government’s nine new initiatives,” says the headline on La Nación.

But farm problems are not limited to the pampas. Thanks to globalisation, they’re sprouting everywhere. “Fears grow over rice crisis,” is the front page story at the Financial Times. “Silent famine sweeps the globe,” reports WorldNet Daily. Thirty-three nations face “unrest” because of food shortages, says the IMF.

All over the world, food fights are breaking out. Not because there is too much food or too little, but because it has gone way up in price. Of course, you could put that another way: the paper money in which food is priced is going down faster than usual. There’s no less food than there was five years ago. But there is a lot more paper money. Modern central banking was invented so that we should have paper money – and have it in abundance. Now, we have so much that it is causing food prices to soar.

But food is hardly in a class by itself. When one bubble pops, the authorities immediately begin pumping up another one. After the dotcom bubble deflated in 2000-2001, up came even bigger bubbles in residential housing and the financial industry. Now, both housing and finance are losing air. But the central banks are still pumping hard. Where’s the air going? Apparently, into commodities. In other words, worldwide inflation of food prices is a monetary phenomenon, as Milton Friedman might put it, not an agricultural one.

To show you the scope of the phenomenon, we pull out a copy of The New York Times from 19 October, 1896. There, it is recorded in black and white that the average wheat price was about $1 a bushel – in gold – during the previous 20 years. An ounce of gold would buy you 20 bushels of wheat. Today, you can buy a bushel of wheat for about $12, which means an ounce of gold will buy about 75 bushels of wheat. In terms of real money – gold – the price of wheat has gone down for more than 100 years. In other words, however fast farmers have added to the world’s wheat output, central banks have outdone them, planting far more acreage in paper money.

And now that governments have caused a crisis, they are hard at work making it worse. In Argentina, the farmers are few; city dwellers are many. Argentina’s Peronistas can do the maths. They make out the farmers – historically patrician landowners with large holdings – to be greedy and insensitive. The politicians imposed a 49% windfall tax on foreign sales. The measure should lower prices for Argentine consumers and raise money for the government, they reasoned. It seemed like a no-brainer. That is, until the Gauchos blocked the roads into Buenos Aires and threatened to starve the city.

In America, the maths is different, but the result is equally imbecilic. There aren’t many farmers out on the prairie, but in Washington there are more farm-state US senators than pigs. They push and shove up to the taxpayers’ trough to get huge subsidies for their hometown campaign donors – lately, in the form of bio-fuels. Corn-fed ethanol may make no sense in environmental or energy terms, but it lubricates the big wheels of national politics. In the event, it takes a third of the US corn crop out of the food chain and puts it to use in the drive train – further driving up grain prices. With bread prices on the rise, politicians feel compelled to intervene. And every intervention falls upon the crops like a cloud of locusts.

Last Friday’s 10% spike in rice prices came as governments moved to corner the market. Three billion people, many of them with very marginal incomes, eat rice every day. The price of rice rose 50% in the past two weeks, causing Thai farmers to sleep in their fields to protect their harvests, while the Philippines posts armed guards at its granaries. Vietnam, India, Kazakhstan and China have all restricted foreign sales. The exporters are coming under pressure to export less – in order to lower prices at home. The importers, meanwhile, have no choice but to try to get as much of it as possible, as soon as possible, in order to head off shortages. Result: a run on rice.

India’s trade minister warned hoarders: “We will not hesitate to take strong measures…” Of course, hoarding is exactly what a smart family should do. Most likely, there will be runs on other commodities, too – and then a run on gold itself. People will want something real… something sure… something with which they can buy rice, without having to worry about it doubling in price two weeks later. That something, traditionally, is gold.

Hoard it now, while you still can.
