1. -- U.S. stock futures were pointing to a higher opening for Wall Street on Thursday and European stocks posted tentative gains ahead of a meeting of the European Central Bank.

3. -- U.S. stocks on Wednesday finished mixed as equities struggled to hold slight highs in the closing minutes of the session after the latest evaluation of the U.S. economy from the Federal Reserve offered little certainty on the outlook of interest rates.

4. -- Crude oil prices in the U.S. rose 0.4% early Thursday to $49.20 a barrel as OPEC ministers tempered expectations of a production deal as they headed into a meeting to discuss output policies.

The 13-nation cartel was widely expected to stick to the hands-off policy it has pursued for the past 18 months, but a last-minute proposal emerged on Wednesday to reintroduce a collective output ceiling, The Wall Street Journal reported. The Organization of Petroleum Exporting Countries had scrapped output targets at its last meeting in December, a move that contributed to oil prices hitting 13-year lows over the winter, the Journal noted.

On Thursday, energy ministers said they would take up the debate behind closed doors at their headquarters here in Vienna. Nigeria, Algeria, Venezuela and Qatar want a ceiling setting an overall output target for OPEC, but Iran, which like all OPEC members holds a veto over decisions, said it was opposed.

8. -- Federal regulators proposed a significant clampdown on payday lenders and other providers of high-interest loans, saying borrowers need to be protected from practices that wind up turning into "debt traps" for many, the Associated Press reported.

The Consumer Financial Protection Bureau's proposed regulations, announced Thursday, seek to tackle two common complaints about the payday lending industry.

The CFPB proposed that lenders must conduct what's known as a "full-payment test." Because most payday loans are required to be paid in full when they come due, usually two weeks after the money is borrowed, the CFPB wants lenders to prove that borrowers are able to repay that money without having to renew the loan repeatedly.

Secondly, the CFPB would require that lenders give additional warnings before they attempt to debit a borrower's bank account, and also restrict the number of times they can attempt to debit the account. The aim is to lower the frequency of overdraft fees that are common with people who take out payday loans, the AP reported.

"Too many borrowers seeking a short-term cash fix are saddled with loans they cannot afford and sink into long-term debt," CFPB Director Richard Cordray said in a prepared statement.
