"Many financial analysts and notable economists are worried that the combination of pent up demand and fiscal stimulus will cause inflation to spike, prompting the Federal Reserve Bank to raise interest rates to prevent inflation from spiraling out of control."

The people who have the ability to create inflation with their spending didn't get stimulus checks. At best they might have driven the price of used cars slightly upward. Those financial analysts and "notable" economists are so far out of touch with the main street economy that their only clue comes from the aggregate money supply as a percentage of a totally irrelevant GDP. A family being able to stay in their home or maintain their normal diet is not inflationary, regardless of how much money creation it takes.
