As part of a now lengthy chain (one, two, three, four) on US allies and the likelihood of US retrenchment (hat-tip to Andrew Sullivan for referencing this chain of posts yet again), I argued that American hegemony, despite America’s huge debt and deficit, is more financially stable than almost anyone expected. Because foreigners’ appetite for dollars seems unquenchable and because we print the global reserve currency, borrow in it, and face no serious reserve challengers (the euro and RMB maybe, see below), US can exploit this ‘exorbitant privilege’ far worse than anyone ever thought.
For example, I think almost everyone expected the bond-market to turn against the US in the last decade given: exploding debt and deficits, huge welfare state expansions like Medicare part D and ObamaCare, the expensive and financially-unplanned GWoT, China’s relentless ascent, the Great Recession, and two rounds of quantitative easing. Wow – that’s a helluva list. Despite all that, interest rates and inflation are low, because we can exploit (and have) that exorbitant privilege. Stein’s Law says there must be a limit, but I think almost everyone is amazed at just how deep confidence in the dollar goes.
More simply put, all this means is that foreigners so want dollars, that America can just print more and more dollars without consequent inflation, and borrow from foreigners a lot cheaply (because they want those dollars so badly). This means America can borrow and/or just print huge amounts of money at very low interest and inflation rates. That is ‘exorbitant,’ because no one else can do that without Greece-style financial trouble. We can borrow at low interest rates (the rate on the US ten-year bond is around 1.5% right now) and print lots of money (the recent quantitative easings, e.g.) without suffering like so many others who over-borrow and run the printing press. Barry Eichengreen’s book on this is helpful if you don’t quite get it.
Vikash Yadav gave such good commentary on this tangle over at Duck of Minerva, that I have reposted our full debate on US borrowing and hegemony below. Warning: it gets fairly wonky, so please be sure to read the OP. Also, further IPE are comments wanted. Specifically, someone tell me please when the US will finally hit the ‘soaring’ inflation and interest rates regularly predicted by deficit hawks at the WSJ or CNBC? This is what Romney means when he says we will become Greece, but I just don’t see any evidence of that. Does anyone have a good guess on the timeline for exploiting the exorbitant privilege? When does it finally give way? When do foreigners turn against us in the bond market? As I said in the OP, I think it (super cheap US borrowing) has gone on already far longer than anyone expected. But I also think that a 100% debt-to-GDP ratio might be the bond-market turning point. That is a pretty big psychological benchmark.
So here is our debate on this:
