Wharton Professor Jeremy Siegel says the surge in oil prices won't be a big problem for inflation as natural gas keeps plummeting

• The surge in oil prices on Monday won't be a problem for inflation, according to Wharton professor Jeremy Siegel.
• Siegel said while oil prices spiked, natural gas prices have been dropping steadily.
• "Natural gas, which is more important for heating and electricity generation, actually bumped to new lows," Siegel said. 

The 6% surge in oil prices on Monday stoked investors' fears that inflation could come back strong, but Wharton professor Jeremy Siegel is not particularly worried.
