LONDON: British finance minister Rishi Sunak is expected to announce an initial 12 billion pounds of capital and 10 billion pounds of guarantees for the new UK Infrastructure Bank in his budget statement next week, the government said on Saturday.

It said this will help the bank, which will launch in the spring and operate UK-wide, unlock billions in private finance to support 40 billion pounds of infrastructure investment.

The bank will offer a range of products, including equity, loans and guarantees, which can be tailored to support the needs of private sector infrastructure projects, in sectors such as renewable energy, carbon capture and storage and transportation, the government said.

It will also offer infrastructure loans to mayors and local authorities at low rates to help fund projects.

"We are backing this bank with the finance it needs to deliver modern infrastructure fit for the 21st century and create jobs," said Sunak.

The government said he is also expected to commit a further 375 million pounds to co-invest alongside the private sector in high-growth, innovative UK firms.

While Sunak's March 3 budget will include a new round of spending to prop up the economy during what he hopes will be the last phase of lockdown, he will also probably signal tax rises ahead to plug the huge hole in the public finances.

In an interview with the Financial Times, Sunak said he would use the budget to level with the public over the "enormous strains" in the country's finances, warning that a bill will have to be paid after further coronavirus support.
