The most damning conclusion from a study of
nations with over 90% debt to GDP is that the period of stagnation and lower growth lasts on average 23 years. Such a conclusion means the U.S. slowdown– which began in 2007– could last until 2030– according to a National Bureau of Economic Research paper by Harvard economist Kenneth Rogoff and Carmen Reinhart (co-author of “This Time It’s Different”) and her husband, Vincent Reinhart, chief economist at
Morgan Stanley.
“The long duration belies the view that the correlation(between 90% public debt and GDP) is caused mainly by debt buildups during business cycle recessions. The long duration also implies that cumulative shortfall in output from debt overhang is potentially massive. WE find that growth effects are significant
even in many episodes where debtor countries were able to secure continual acess to capital markets at relatively low real interest rates. That is, growth-reducing effects of high public debt are apparently not transmitted exclusively through high real interest rates.” -

I didn't need a study to know massive debt is a drag on the economy but I guess some people aren't aware of that fact. The US debt to GDP ratio is 92.7% and still growing. The fact that we can still sell bonds (long term debt securities) is not an indication that everything is hunky dory, we're in real trouble.
Then there's interest rates. Interest rates for the bonds we sell to fund our deficit spending will have to get bigger to attract investors. Higher interest rates means a higher debt service bill. We currently pay about $250 billion of the federal budget for debt service but that number will grow exponentially as interest rates are raised to attract debt purchasers. A 1% rise in rates would push our annual debt service to $332 billion, about 1/10 of the entire federal budget. Our AAA rating has already been downgraded and without drastic changes to our spending policy that reduce our debt to GDP ratio, further downgrades are eminent.
The PIIGS - Portugal, Italy, Ireland, Greece, and Spain all had their debt to GDP ratio exceed 120%, they saw their bond ratings downgraded accordingly, and they are the drivers of the European debt crisis. Greece has a debt to GDP ratio of 160% and their 10yr bond rate is a staggering 16.98%, Portugal 7.87%, Spain 5.64%, Italy and Ireland both have the lowest debt to GDP ratio of the group and have 10yr bond rates of 4.87%. At 4.87% bond rates, the US would be looking at roughly 3/4 of a trillion dollars annually JUST to service our debt, that would consume nearly 1/4 of our entire federal budget.
So while I know it's tempting to think that because we aren't feeling the sharp pain of debt right this moment, it's coming and it's gonna hurt like hell. It's like falling out of a hot air balloon from cloud level... Freefall doesn't hurt at all, it's the landing that's a bitch. Either we use the time we have to build a parachute or continue to fiddle while Rome burns.
