Huge exposure to American mortgages is expected to result in Citi taking a $10 billion hit to its accounts, dragging the bank to a first-quarter loss of almost $3 billion. Some analysts believe Citi’s write-downs could stretch to as much as $12 billion.

It is expected to knock a further 20% from the value of its sub-prime holdings, in spite of the fact that it announced $18 billion of write-downs only three months ago.

The new rash of Wall Street losses and write-downs come in addition to the billions that have already been recorded.

The world’s biggest banks have suffered losses and write-downs totalling almost $250 billion since the beginning of 2007, according to analysts. Last week the IMF shocked markets by saying that global losses from the credit crisis could rise to $945 billion.
