Investors cheered the news, because it makes the situation less complicated for the Federal Reserve, says Giuseppe Sette, the president of market analytics firm Toggle AI.
"Inflation's downward trend makes life easier for the Fed," he said. "However, speculation that the central bank could cut the rate toward the end of the year should be tempered by the Fed's own communication to the contrary. Traders would do well to remember that rates historically are always higher than inflation except during a recession."
The financial markets popped following the CPI data before the opening bell, as the leading benchmark indexes were up at least 0.6 percent in pre-market trading.
The U.S. Treasury market was red across the board, with the benchmark 10-year yield down about 7 basis points, to around 3.36 percent.
