Castle Trust Bank Acquired by Sixth Street and Bayview

Castle Trust Bank has been acquired by vehicles backed by Sixth Street and affiliates of Bayview Asset Management. The new owners have also agreed to commit additional capital to support growth across the business.

According to the report, the investment will be used to expand Castle Trust Bank’s retail savings franchise, broaden its product offering, and attract more customer deposits. The commitment also includes enhancing specialist property and retail finance through Omni Capital Retail Finance.

Martin Bischoff will remain as CEO of Castle Trust Bank following the acquisition. The report states that the bank has grown customer savings balances to more than £1.6bn, built a specialist property finance loan book of more than £1.1bn, and a retail finance loan book exceeding £200m.

The acquisition and capital commitment are intended to support further investment in the bank’s customer proposition and expansion across retail savings, specialist property, and retail finance. The report highlights that the bank aims to pursue additional growth opportunities while maintaining a disciplined focus on risk and delivering sustainable outcomes for customers, colleagues, brokers, retailers, and partners.

This development is relevant to UK letting agents and inventory clerks as Castle Trust Bank is active in specialist property finance, which may impact lending options and services available in the buy-to-let and property management sectors.
