Barclays (BARC) today announced its long-expected cash call to raise £4.5bn and bring in new investors, say the FT. The move is designed to lift Barclays' core equity Tier One capital ratio from about 5%, one of the lowest among European banks, to 6.3%, well aboveits 5.25% target. As you can see from the attached chart, Barclays paid a big dividend in March this year hence the spike in the percentage of its Market Cap on Loan for dividend yield enhancement reasons. However, you will see that there has also been a general increase in short interest too. Since June 6th the %MCOL has risen from 6.1% to 7.2% today, juxtaposed with a fall in share price from 342p on June 17th to 308p today. There are 7.57 Days to Cover. Interestingly, Utilisation is very low at 15%, so it is still easy to borrow the stock.
