Reserve Currency: I'll Reserve Judgement On That

Nouriel Roubini came out with an Op-Ed piece in the New York Times this week. In it, he raises a warning flag. The Chinese, who fund the US government deficit by being the biggest buyers of Treaury bonds, and who have a gigantic stockpile of dollars, are starting to make noises that they don’t want the dollar to be the world’s reserve currency anymore.

In the post-World War II economic system, the dollar became the world’s reserve currency. That means that for globally traded commodities, the deals are priced in terms of dollars. World oil prices are in dollars per barrel.

It also means that for a number of currencies, if you want to change over to another currency, you have to use dollars to complete the two halves of the transaction. For example, to convert Danish kronar into Thai baht, you first trade your kronar for dollars, then trade the dollars for baht.

If you want to be part of the world trading system, you have to keep a stockpile of dollars on hand to fund your buying and selling.

Because everybody has to have dollars, that keeps demand for greenbacks high. This allows the government to keep interest rates low in financing the deficit. It also allows American consumers to run up massive trade deficits, since exporting countries have to accept US currency. Our status as the world’s reserve currency keps the dollar strong, leading to low interest rates and inexpensive imports.

Mr. Roubini’s warning is that unless we get our fiscal house in order, the Chinese currency, the renminbi, will supplant the dollar over the next ten years. Historically, reserve currencies have always come from creditor nations, not borrower nations. If the renmenbi surplants the dollar, our currency will fall preciitously in value. This will cause a spike in interest rates as the government will have to entice investors into continuing to fund our deficits. Also, commodity prices will inevitably rise in dollar terms.

I hate to argue against anyone who is advocating more fiscal restraint, but I don’t find Mr. Roubini’s nightmare scenario to be particularly frightening.

First, to function as a reserve currency, the renminbi would have to be widely traded on currency markets, and before that could happen the Chinese would have to allow it to float, or move up and down in value, vis a vis other currencies. But the Chinese keep the value of their money pegged against the dollar. It is only in the last couple of years that even limited trading of the currency has been allowed.

It is precisely because the renminbi is pegged against the dollar that the US continues to run such a massive trade deficit with China. Otherwise the dollar would already have dropped in value against the renminbi, making Chinese imports more expensive. And the Chinese get something out of the deal. US demand for cheap Chinese imports is driving the extremely rapid industrialization of the Chinese economy.

In addition to the practical difficulties (many of which Mr. Roubini himself lists out), as a manufacturing manager I think the benefits of a falling dollar would vastly outwiegh the costs. Yes, commodity prices would increase. But for the last ten years the Chinese have used an artificially low currency to take market share from companies like mine. Instead of continuing to fight one long rear guard action against off-shore competitors, we could use our advantages of lower freight costs, higher productivity, and shorter lead time to take back business that has been lost. Maybe we could even expand into new markets and products.

If being the reserve currency has allowed Americans, both collectively and individually, to be irresponsible, than losing that status would be a change for the better. It is the difference between empowerment and enablement.
