[There are many articles (including one I wrote in college), and even whole books written about Petrodollars – the way that US dollars dominate the world economy by their crucial involvement in all global oil trades. This just happens to be a very clearly written and accessible essay, so I’m reprinting it despite slightly out-of-date numbers. The extent to which the fragility of petrodollar hegemony affects US foreign policy is probably the biggest question mark, but it seems plausible that the much-threatened aggression against Iran has a lot to do with that country’s moves to abandon the dollar for their oil trades. – alex]
Oil prices and the dollar

| The depreciation of the US dollar has been closely bound up with the movement of oil prices, as world oil trade is typically denominated in dollars. Yet this relationship may now be under threat as the dollar continues to depreciate and the US economy tips into recession. In this edition of Macroscan, C. P. Chandrasekhar and Jayati Ghosh examine how oil prices have changed with different numeraires, and consider the implications for the future of the oil-dol lar nexus. |
The relationship between oil and the US dollar has been at the heart of the way international economic relations have been organised for more than half a century.
International capitalism has relied on the US dollar as the basic reserve currency, and has therefore granted it an essential degree of stability for several decades despite the large external deficits run by the US and the periodic swings in its valuation in currency markets.
More than half of aggregate world exports are denominated in dollars; more than 80 per cent of all international currency transactions similarly involve dollars.
Loans made by the IMF and other multilateral institutions are denominated in dollars. More than 60 per cent of the foreign exchange reserves held by central banks of all countries are in dollar assets.
This has obviously meant huge advantages for the US. It has allowed the US economy to benefit from access to imports that can effectively be paid for simply by printing dollars, and has therefore allowed the US to run enormous current account deficits for prolonged periods. It has encouraged the rest of the world to finance these deficits by providing its savings to be held in US or dollar-denominated financial assets, to the point that all the developing regions of the world are also building dollar reserves that directly or indirectly find their way to the US economy.
Dollarisation of oil markets
A key feature of this entire process has been the dollarisation of world oil markets. Oil is the central commodity of industrial capitalism, absolutely essential for the production of essential and widely used goods. All industrial economies, and most developing ones, would grind to a halt with even a moderate disruption of oil supplies.
Most of the world oil trade has operated and continues to operate in dollars, even when the US is not the trade partner. Oil prices are defined in dollars for most oil exporters. As a result, oil importing countries also pay in dollars. The oil-exporting countries accumulate dollar reserves, which have been preferentially invested back in the US because of the zero currency risk involved in this.
Indeed, this recycling of petrodollars has been very significant as a source of finance for US trade deficits in several periods, including in recent times. Other countries also hold dollars for future oil purchase.

The dramatic increase in the price of oil in the past few years could be argued to have accentuated this tendency. As Chart 1 indicates, oil prices have increased dramatically in dollar terms especially from 2003, going up by nearly 2.5 times between 2003 and 2007.
This has obviously contributed very significantly to the wealth of oil exporters, and allowed them to generate balance of payments surpluses and build foreign exchange reserves, which have then been invested dominantly in dollar assets in US markets.
However, this is also the period that the US dollar has been depreciating, especially with respect to some of the other major currencies such as the euro and the Japanese yen. As a result, the change in oil prices has been less striking in terms of these currencies than in terms of the dollar.

Witnessing the unraveling of the global financial system, I find myself gripped by contrasting emotions. While part of me feels like heading for the hills and hoarding cans of sardines, another part of me is giddy, almost celebratory. The tyrannical rule of Wall Street is ending, along with the self-serving free market ideology of Neoconservatives. The massive amounts of fictitious capital created by our corrupt financial system must be destroyed, so we can address our immediate situation on this planet.
I feel sorry for the millions of people who may suffer during a transition that will be extremely difficult. On the other hand, our rapacious economic system is destroying the integrity of the biosphere, threatening our future as a species. Taking a wider perspective, we can see a new social structure that creates sustainable patterns of behavior is necessary, if we want our descendents to continue on the earth.
In my last book, I looked at many predictions of systemic financial dissolution at this time. I discussed the possibility that a financial H-bomb could melt down the economic system while leaving the “tangible assets” — people, infrastructure, land — still standing. I suggested this could be the best thing to happen to our world. Such a systemic collapse is a tremendous opportunity to change the direction of our society. Those who believe civilization can be run according to different principles — humane, equitable, and collaborative ones — need to step forward now with concrete proposals and put ideals into practice.
Several factors made the collapse of the global financial system inevitable. One problem with capitalism is that it is not self-sufficient, but depends on the constant availability of new markets, forcing expansion by creating ever-increasing amounts of debt. We now have a globalized world market, so exploitation of new territories can no longer take place. As Naomi Klein analyzed in The Shock Doctrine, this led to a policy of “disaster capitalism,” where cataclysms like hurricanes and terrorist acts were seized as opportunities to redevelop internal markets. Such a practice is inherently unsustainable.
Another crucial element that is rarely discussed in the media is the connection between the current financial meltdown and peak oil. Just as our debt-based economic system needed new markets to penetrate, it also required an ever-increasing supply of cheap energy to fuel its expansion. The decreasing supply of fossil fuels relative to global demand has brought the second law of thermodynamics into play, breaking the delusionary spell cast by the financier-sorcerers, who decoupled financial value from real value back in the early 1970s. When we consider the permanent reduction in the supply of cheap energy combined with the lack of new markets, it is obvious the amassed debts will never be repaid. Read the rest of this entry »
