Japan's government will compile an extra budget of some 3 trillion yen ($18.88 billion), Prime Minister Sanae Takaichi said on Monday, stoking concerns over fiscal expansion that could further strain the country's already stretched finances. The extra budget comes as the government decided to use roughly half of its 1 trillion yen contingency reserves to fund subsidies aimed at curbing utility bills, increasing the need to replenish reserves amid the risk of a prolonged Middle East crisis.
