Lloyds TSB Commercial has promised to pass on any further Bank of England base rate cuts to business insurance customers.
The bank says that business insurance customers with variable rate loans and overdrafts will be given a full reduction if the monetary policy committee makes another rate cut on Thursday.
"We are honouring the pledge made in our small business charter to pass on, in full, any base rate reductions until the end of 2009," said John Maltby, managing director of Lloyds TSB Commercial.
He added that the institution is committed to helping business insurance customers by "easing pressure" and "providing more certainty" regarding overdrafts and loans.
This week, Highlands and Islands Enterprises announced that it has launched a helpline offering advice to firms during the credit crunch.
Businesses can get free, tailored advice as well as contact details of other organisations which might be able to help them, such as HM Revenue and Customs.
