The MSMs all have short items on the House Committee on Oversight and Government Reform’s unusal subpoena of the Federal Reserve, demanding records related to Bank of America’s acquisition of Merrill Lynch during the panic months last fall.

The issue is whether the Fed, as the Financial Times puts it, put “undue pressure” on BoA to do the deal even after the scale of Merrill’s problems became apparent as it moved to close.

FT got a peak at testimony that BoA CEO Ken Lewis has prepared for an appearance before the committee on Thursday:

In his prepared testimony, seen by the Financial Times, Mr Lewis says that the Treasury and Fed “expressed significant concerns about the systemic consequences and risk to Bank of America” of declaring a “material adverse change” – a step that would precede canceling the transaction.

The subpoena itself is puzzling; if Congress is going to subpoena the Fed every 20 years or so, this would not be the topic. The Fed had already cooperated, though apparently not enough. And of all Fed moves lately, why this particular deal? Merrill was so toxic there were no good options from taxpayers’ point of view, so whose interests are at stake—BoA shareholders’?

The real interest is that the tiny item points up a yawning gap in major news outlets’ coverage of the Fed generally, a gap filled to the extent possible by financial blogs, notably Naked Capitalism, which picked up the item this morning.

I don’t think the general reader, or even the close business press reader, fully appreciates the scope of what the Federal Reserve has done in its attempt to rescue the financial system in the months following the Lehman bankruptcy. Put it this way, the next installment of the Transformer series might star the U.S. central bank.

Bloomberg, it should be said, has been trying to keep track. This story from February by Mark Pittman and Bob Ivry, notes that the U.S. government generally had committed $9.7 trillion to solving the financial crisis, “enough to pay off more than 90 percent of the nation’s home mortgages…enough to send a $1,430 check to every man, woman and child alive in the world,” with the Fed playing a leading role.

Here’s how the figure breaks down:

The promises are composed of about $1 trillion in stimulus packages, around $3 trillion in lending and spending and $5.7 trillion in agreements to provide aid. The total already tapped has decreased about 1 percent since November, mostly because foreign central banks are using fewer dollars in currency-exchange agreements called swaps.

And here’s where the Fed’s balance sheet stood at the time:

Federal Reserve lending to banks peaked at a record $2.3 trillion in December, dropping to $1.83 trillion by last week. The Fed balance sheet is still more than double the $880 billion it was in the week before Sept. 17 when it agreed to accept lower-quality collateral.

The point isn’t to judge whether the Fed’s moves are warranted, a good idea, unavoidable, or what, only that the agency isn’t the same one that we’re used to. And it operates outside the oversight of Congress, except for the odd subpoena, and, in this case, on a side issue at that.

Now, of course, there is a lot of Fed watching, that is to say, commentary and interpretation of its official actions. And among the MSM, Bloomberg has led on Fed coverage, especially on prying loose records on the quality of collateral banks are posting in return for Fed loans. But to say that more coverage of the Fed as an institution is warranted is to understate the case.

If you think the Fed’s inspector general, Elizabeth A. Coleman, is on top of it, this exchange with Floriday Rep. Alan Grayson, posted by Zero Hedge, will disabuse you of that idea.

Grayson: “If your agency has in fact, according to Bloomberg, has extended more than $9 trillion in credit, which, by the way works out to more than $30,000 for every man, woman, and child in this country, extended I’d like to know if you’re not responsible for investigating that, who is?”
