I would have to look through my many documents, because I don't know offhand. However, I can say that the repercussions would be in the billions of dollars.
It's risky to think that, because interest rates are low, we can spend and increase our debts without worrying about it. If interest rates ever go up, it would cost us a great deal collectively.
Forecasts don't point to a significant increase in interest rates in the medium term, but we can always have surprises. Given that interest rates are historically low, can they be much lower? They can go down a little, but not much. In short, there is much more room to go up than down.
