Biden stimulus increased inflation by 4% in the USA.
Mr Biden’s stimulus did, however, put a rocket under inflation. In April “core” consumer prices, which exclude energy and food, were 13.4% higher than when he came to office. They have risen more than in other g7 countries, and their acceleration coincided with the introduction of Mr Biden’s stimulus. Research suggests that, even by September 2022, the largesse was pushing up core inflation by about four percentage points.
