Let's lay it out there for you folks.
The Fed has a "line in the sand" beyond which they take actual capital losses on their portfolio.
If rates rise they get rammed from both front and back as the payment of interest on excess reserves will force them to pay out coupon on funds at the same time the capital value of their assets will decline in ratable proportion to the duration and size of its portfolio.
This is not prospective or speculative. It is mathematically known and factual.
It has been known since The Fed began its intervention.
You have frequently, over the last few years, seen me post about the pincer of mathematics that closes the door on your neck when you try to play with exponential functions and ignore the fact that all exponential functions eventually run away from you and blow up in your face.
The market has completely ignored this fact for the last four years, and worse Ben Bernanke has repeatedly made statements like "The Fed will not monetize the debt" (while doing exactly that) and arguing other such nonsense such as "we must normalize our finances in the medium term" (five years ago, which means that today is the "medium term"!)
The reason it hasn't happened is that Congress has learned that it can "goose" GDP and thus the appearance of the economy's health by spending money it doesn't have, goading The Fed into "buying" those bonds with raw emitted credit.
But let's recap what happens when you do this.
Let us assume there are 10,000 units of currency and credit in the system, and 10,000 units of output. You must not denominate the output in units of currency because if you do then you've created an open fraud in your claimed statistical figures, so let's denominate them in hours of labor.
So now I can exchange one hour of labor for one unit of currency or credit.
Now the government wants to "goose" the economy, and it convinces The Fed to emit 10,000 more units of currency and credit. Note that the amount of output does not change in the immediate sense, and may not change at all!
But what does change is that each unit of currency and credit now only buys one half of an hour of labor.
Of course this is a simplistic example. In the real world some people find ways to use leverage to convince people that "profits will rise", and stock prices go higher. They seem to be rather happy with this state of affairs. And some people may, seeing all this "money" (really credit) flying around, that they should hire more people and build more things.
But there's a problem -- the guy working for a living has to pay more for his gas, food and medicine, and his salary hasn't gone up as the amount of effort he is delivering into the economy hasn't changed.
He is poorer in terms of what he can buy.
To whom do you think all those businesses that are going to make "record profits and expanding margins" are going to sell their products and services?
So why wasn't the feedback immediate and devestating?
Ask yourself this -- what happened to keep colleges from instantly going bankrupt when they doubled their tuitions or more within a few years?
That's right -- you give people that "credit" -- that is, debt. You allow them to defer paying. But by doing this you make the problem worse, whether the credit is issued to the government, to a kid in college or to you buying a car or medical care, because what you've done is created false demand for which nobody can pay without your "cheap credit."
That, classical economics tells us, causes price to rise because demand expands.
And now I can't pay for college without that credit at all but you have intentionally made it necessary for me to access and use that credit to maintain my standard of living!
What happens when I can't absorb any more debt -- when that exponential expansion runs into the hard wall of economic output and people's ability to pay?
The system crashes.
As it did in 2000 when the government willfully and intentionally ignored hundreds of bogus IPOs and outrageously "rosy" (and mathematically BANKRUPT) projections of "profits" for Internet companies that ultimately were proved false by the dozens.
As it did in 2007 as a consequence of a housing bubble that The Congress and Fed manufactured on purpose after the Tech crash in 2000. The government then went on to shield and protect both The Fed and banks, along with itself, from any consequences of its own intentional acts, while you got screwed (again.)
And now as we are running into the wall again with medical, educational and government spending in 2013.
THE RECOGNITION THAT THIS PATH WON'T WORK BECAUSE IT CAN'T BY THE MARKET HAS BEGUN. IT HAS BEEN SERIALLY RUN TWICE PREVIOUSLY WITH THE INTERNET AND HOUSING BUBBLES AND HAS SERIALLY FAILED TWICE! EVERYONE INVOLVED IN DOING IT, FROM THE PRESIDENT TO CONGRESS TO THE FED, KNOWS DAMN WELL THAT IT WON'T WORK BECAUSE IT HAS NOT IN THE PAST -- ANYWHERE IN THE WORLD -- EVER, BECAUSE IT CAN'T.
You're seeing the start of what happened in the early part of 2007, and rather than address this head-on our government is going to the exactly wrong thing and refuse to address it, and as a consequence we're going to get another collapse into already-depressed and therefore non-functional intervention capacity on the part of government and The Fed.
