According to Jin10, economist Jim O'Neill, a former adviser to Prime Minister Burnham, said British Chancellor Healey should avoid raising taxes in the budget and instead accept an "emergency" reduction in fiscal buffer space to cope with the shock from the Iran war. O'Neill said Healey should not fill the fiscal gap in this month's budget by raising taxes on companies and the wealthy, which would "damage" the economy. He estimated Britain's fiscal shortfall at nearly 12 billion pounds, warned that a large tax increase would hurt market confidence, and said he would be "very disappointed" if Healey raised the capital gains tax rate. He also said he feared the chancellor might target banks, adding that he sees higher bank taxes as futile.
