Investors hoping that the Federal Reserve will soon cease its year-long interest rate-hike campaign will be paying close attention to two government inflation reports due out this week.

The Producer Price Index will be reported Tuesday morning, followed by the Consumer Price Index Wednesday morning. Both numbers are expected to come in tame, with neither inflation gauge expected to show more than a 0.2% rise last month.

It would be good news if the wholesale and consumer inflation reports were in line with economists expectations — but with oil prices surging anew, there could be fears that the tame readings could disappear as soon as next month.

Stocks posted strong early gains Monday, but gave most of them back by the close after oil prices surged.
