Sorry for the delay in answering. I forgot this thread… :smack:
Now, there is new data being discussed in this thread and I’m reposting what amounts to a clarification of my reasoning. Have at it.
I’ll have a shot at answering your question, though I’m no economist.
Debt is a liability. Whenever you lend money to someone, you wager that they will live and prosper long enough to repay you, preferably with an interest rate that meets or exceeds inflation.
The odds of that happening are never 100%. The longer the time period, the worse the odds are for the lender to get the (entire) loan back. When lenders to the U.S get scared, they might decide to sell dollars at a loss to get what is perceived as a more stable currency (euros, swiss francs, yens). Anyone who traded their dollars for euros in the late 90s would be very happy now
Thus, the greater the debt, the less faith lenders have they’ll be repaid in time with strong currency and the lower its international market-value.
Of course, I might be very wrong.

This is a good start, but it isn’t exactly correct. The short answer is that a country’s large national debt (better characterized as a percentage of GDP) puts downward pressure on its currency.
The debt is further re-balanced (pushed upwards) by the interest rate paid back on the bonds, T-notes, etc. However, even this doesn’t even tell the whole story, though your little explanation does figure in the intangibles, i.e. lack of consumer confidence. That is why the Japanese economy isn’t in hyperinflation though having a national debt something like 132% of GDP, where as a weaker economy might be pushed to edge of bankruptcy or panic if it nearly defaults on its loans (not concrete examples, but South Korea, Thailand, and Mexico come to mind).
