Well, this raises the question of whether the past tells us anything about the future, and if so what? There’s a common wisdom attributed to Mark Twain (why is it that aphorisms are always attributed to Twain or Winston Churchill?) that goes: “History doesn’t repeat itself, but it often rhymes,” and this is the position that most educated future-thinkers would hold.

So what would the ‘rhyme’ be? From cases such as Argentina, Russia, South Africa, and many developing world countries over the past 50 years: lenders loose confidence in a country’s ability to repay on its national bonds and stop lending; the country is faced with a choice of drastic spending cuts (great social and humanitarian cost) or major tax increases (pointless, because it stifles business, therefore lowers tax revenue) or default. Going broke, into national “Chapter 11,” suing for time and ‘debt restructuring’ becomes the best among the bad options event though it pretty much ensures a deep and dark recession.

Thinking the unthinkable

Could this be the future of America? As I’ve written before here and other places, after the ‘unimaginable’ Credit Crunch was ignored due to its ‘low probability,’ it’s a relief to know that remote but plausible outcomes with serious consequences are getting attention, at least in the Washington Post.

Clearly major economies are in a more precarious situation than they were 5 years ago. Too much debt is always precarious, for the smallest household or the biggest country alike. On the other hand, an economy’s size and enduring wealth counts too. As Samuelson observes, it created the unexpected effect in Japan’s case where debt at 200% of GDP (America’s is currently about 40%) should have raised the cost of its debt (lower confidence of repayment) but this hasn’t happened because domestic Japanese households and businesses rather than foreigners have easily (and confidently) bought the debt — and this may well hold true for the U.S. too. In other words, the rhyme may go this way.

The ‘more likely’ future is incremental raising of taxes and lowering of public service provision as Western economies incrementally claw their way back to stability. But at least this default wild card on the margins of plausibility has the oxygen of some attention and this is no bad thing. As with all good foresight work, it predicts nothing, but it does allow us to think through the roadmap to the outcome, and press for the right decisions now, in plenty of time and in a measured way.

Predictions of the dollar’s demise are as old as the greenback itself of course, but over recent weeks the specter of the dollar heading way way below its trading range — a dollar crunch — has entered the zone of the credible, or, in scenario terms, the ‘cone of plausible uncertainty.’ That means decision-makers with lots at stake are taking it seriously.

Like the British pound, the dollar has been under a cloud due to perceptions of economic fallout from the credit crunch and global recession, but particular questions about the US currency have recently surfaced, driven by reports [Robert Fisk's 'The Demise of the Dollar' story in The Independent (Oct 6)]  that “Gulf Arabs are planning – along with China, Russia, Japan and France – to end dollar dealings for oil, moving instead to a basket of currencies including the Japanese yen and Chinese yuan, the euro, gold and a new, unified currency planned for nations in the Gulf Co-operation Council” (Saudi Arabia, Abu Dhabi, Kuwait and Qatar).

The subtext is far from merely financial. Practically, it would mean that on any day, the real cost of oil to US consumers and businesses would go up or down depending on the strength of the currency. This is something America is not used to. But, more deeeply, dropping dollar-denomination of oil is a direct shot across the bows of Washington’s say over oil affairs, and the hegemony of the dollar as the dominant global reserve currency.

De-dollarizing oil would not in itself push the US currency below its 25-year range. But it is portentous of the clear trend to a genuinely multi-power world, for better or worse, in which the dollar will get no favors. That will push the dollar down, at least while the news and fallout make their way through the financial and real economic systems.

Rumors of de-dollarization have been hotly denied, as further reported here, but as the Independent points out, denials are to be expected, and are always issued in these situations. They mean nothing. Even cub reporters know that.

Scenario thinking

What’s particularly interesting to me is that a ‘scenario’ of dollar demise has become not only plausible in the mainstream view of the future, but scenario thinking is being used as a way to consider the nature of this outcome, and how best to respond without predicting the outcome either way. As recently as directly pre-credit crunch, the media question would have been: ‘what is the best prediction for the dollar (or the housing market, or credit default swaps?) and that, rather then scoping out the implications of the lesser-likelihood, would have dominated the discussion.

So, what struck me forcefully in the Business Week video interview above, where BW Chief Economist Mike Mandel interviews the news magazine’s Economics Editor Peter Coy (see Coy’s underlying story here), is how the less-likely, non-predicted, but very significant outcome is actively addressed:

Says Coy: “It’s so hard to know what the dollar is going to do. We don’t argue that we know… what we do is we say, ‘it could happen’ and let’s take that possibility seriously, in the same way we should have taken the possibility of falling housing prices seriously…”

This is not formal scenario-building of course. But it is, fundamentally an adoption of the framework, saying in the classic ‘scenarios’ way: “we can’t predict if it will happen or it won’t, but if it does it will have significant impact. So let’s just ask: ‘what if ‘ it does and explore the outcomes and our responses. What will the word look like? What would be the implications, the knock-ons and spinoffs? If it comes to pass, what would be wish we had done today?”

Perhaps failing to predict the credit crunch has dented predictors’ halos enough to cause a mini-zeitgeist-shift towards the only real way to cope with important uncertainty: exploring all outcomes that pass the plausibility and significance test, whether or not we actually believe they will happen.
