NEW YORK (TheStreet) -- Stocks kicked off the new week in better fashion, logging gains of more than 1% on Monday and recovering year-to-date gains on the S&P 500 and Dow Jones Industrial Average.

The S&P 500 was up 1.4%, the Dow climbed 1.3%, or 226 points, and the Nasdaq added 1.2%.

But, though Wall Street rebounded, the anxieties of last week persisted. Wall Street has been increasingly volatile over the past week as investors debated the likelihood the Federal Reserve would hike rates as soon as June.

"The US will likely enter a new phase of the monetary policy cycle," Societe Generale's Aneta Markowska and Brian Jones said. "We expect the FOMC do drop the 'patient' language on Wednesday, which would mean that from June onwards every meeting is in play for a potential rate increase."

The Fed will kick off a two-day policy meeting on Tuesday morning with a press conference scheduled for midafternoon Wednesday. 

Crude oil plummeted to six-year lows on Monday, though recovered a level above $43 a barrel after dipping to just over $42 earlier in the session. By market close, West Texas Intermediate was down 2.3% to $43.87 a barrel. The fresh lows added to losses suffered last week as rig cuts only dented production and the U.S. faces a possible storage crisis in coming months.

"Selling pressure was generated on Friday by the International Energy Agency, which warned that storage capacities could soon be exhausted in the U.S.," said Commerzbank analysts in a note. "The IEA only expects the situation to improve in the second half of 2015 when growth in U.S. oil production looks set to slow."
