The National Wealth Fund has taken over the U.K. Infrastructure Bank, set up by the previous government. The new government is adding £5.8 bn in current plans to the £22 bn of inherited investment potential in the Infrastructure Bank and widening its remit and powers a bit. The Infrastructure Bank lost £22 m in its last reported year, 2022-23.
The idea is to finance projects and ideas the private sector is nervous about, and to crowd in private finance to projects by putting up some of the capital or offering guarantees. Taxpayers should expect returns from these investments at a minimum to cover the taxpayer costs of borrowing all the money to put up the capital. Let us call that 4.5%. It would also be good to provide for capital repayment at say 3% a year. A private investor would clearly expect a risk or equity addition to the return, say at least 5%. That takes the total to 12.5%.
It seems unlikely the National Wealth Fund will aim for this. They may well be satisfied with a low single figure return, and may at least in early years run with more losses. They need to guard against being seen as the last resort for high risk projects the private sector thinks will go under or as a first resort for a potential private sector consortium that sees the Fund as capable of absorbing risk through guarantees or high risk debt tranches which gives the private investors a less risky ride.
The state borrowing at 4.5% to invest in projects should ensure that the overall portfolio can avoid losses and pay for the borrowings.
