Macquarie has raised £579m (€730m) for its infrastructure debt strategy in a first close.

The fund, which will invest in inflation-linked debt in the UK, attracted commitments from pension schemes, Macquarie said.

Macquarie said capital raising was continuing with “strong momentum�.

At launch , James Wilson, the company’s portfolio manager for infrastructure-debt investment solutions, said it had estimated inflation-linked borrower demand at around £4bn.

An unnamed UK pension fund made an initial £200m commitment to the fund, which is targeting the utility sector, renewables and offshore transmission owners (OFTOs).

The fund will concentrate on investment-grade opportunities on a smaller scale, starting from £10m – for which there is more demand, Wilson said at the time.

The new fund will target average returns of 250 basis points above index-linked Gilts.

Investors in the fund will be paid semi-annually.

Macquarie said its wider UK, inflation-linked, infrastructure-debt strategy, which includes the fund as well as separately managed accounts, has now raised £979m from 11 major institutional investors.

The company expects commitments for its global infrastructure debt platform to reach £2.2bn by the second quarter of next year.

Andrew Robertson, co-head of Macquarie’s Infrastructure Debt Investment Solutions (MIDIS), said inflation-linked commitments complemented the company’s existing mandates in both fixed and floating-rate debt in the UK and Europe.

“We are finding that borrowers are often looking for a mix of inflation-linked and fixed or floating-rate debt,� Robertson said, adding that it had received “strong interest� from European and Asian investors.
