The IMF is upgrading its economic outlook this year for China, India and Europe while modestly lowering expectations for the United States and Japan. But it says worldwide progress against accelerating prices has been slowed by stickier-than-expected inflation for services, from airline travel to restaurant meals. Overall, the IMF said Tuesday that it still expects the world economy to grow a lackluster 3.2% this year, unchanged from its previous forecast in April and down a tick from 3.3% growth in 2023.
