In the past four months, the month on month increase in US CPI has not been less than 0.3% (compared to 0.3% in December and January last year, and further reaching 0.4% in February and March). So, if CPI continues to show this resilience, how will US inflation develop this year? The forecast chart from research firm Bespoke shows that if the month on month CPI growth in the United States continues to remain at 0.3%, the year-on-year CPI is expected to return to the "4 eras" by the end of the year. If it remains at 0.4%, year-end inflation may even touch the threshold of the "5 eras". Given that the current surge in commodities continues to add pressure to price recovery, the risk of "secondary inflation" in the United States cannot be underestimated.
