The high cost of living, the result of snarled supply chains because of the COVID-19 pandemic, is a political nightmare for President Joe Biden.

US consumer prices increased solidly in December as rental accommodation and used cars maintained their strong gains, culminating in the largest annual rise in inflation in nearly four decades, which bolstered expectations that the Federal Reserve will start raising interest rates as early as March.

The report from the Labor Department on Wednesday followed on the heels of data last Friday showing that the labor market was at or near maximum employment.

Fed Chair Jerome Powell on Tuesday said the US central bank stood ready to do what was necessary to keep high inflation from becoming "entrenched," in testimony during his nomination hearing before the Senate Banking Committee for a second four-year term as head of the bank.

The high cost of living, the result of snarled supply chains because of the COVID-19 pandemic, is a political nightmare for President Joe Biden, whose approval rating has taken a hit.

"The Fed is going to be forced to begin raising rates in March and depending on the political pressure on them – from both sides of the aisle – they are going to have to raise rates four or more times in this year and potentially more than that next year," said Chris Zaccarelli, chief investment officer at Independent Advisor Alliance in Charlotte, North Carolina.
