Regional banks, mutual and non-bank lenders won't rule out taking the opportunity to bolster profits should the major banks copy Westpac's interest rate rise, according to the AFR. For example, non-bank lender Firstmac - which has no capital raising to do or regulator imposed investor loan growth cap - said it would be raising rates in line with the majors if all follow Westpac's lead. The first part of the bookbuild for Westpac's rights issue was drawing to a close today, with lead managers expected to wrap-up the $1.5 billion to $2 billion institutional rights issue, according to the AFR's Street Talk. This will provide a strong indication as to where Westpac shares should trade come Monday.  Bids were to be made from $25.50 a share, which was a 13.1 per cent discount to the theoretical ex-rights price. Early expectations were that the book was likely to be done at $28 to $28.50 a share.
