The bank should:

Be publicly-owned and mission-driven, focused on supporting Scotland’s economic priorities and promoting inclusive growth

Operate in an ethical and transparent way

Cowork to crowd in, not crowd out, private sector investment

Be supported by long-term capitalisation of at least £2 billion over the first ten years

Become self-sustaining in the longer term, raising its own capital to fund investments

Provide long-term, patient finance for both smaller firms and larger projects

Create opportunities and new markets for the private sector to invest in’
