NEW YORK, June 30 (Reuters) - U.S. stock futures on Monday pointed to a flat market open as oil climbed to a new high and more gloomy forecasts for the financial sector threatened to push the Dow average into a bear market.
The blue-chip average is on track to end the first half of the year on Monday with its worst performance for a first half since 1962 as the market faces pressure from spiraling oil prices, weak profit outlooks and a credit crunch that has triggered heavy losses at banks.
In the latest sign of doubts about the financial sector, analyst Dick Bove forecast a big annual loss at Merrill Lynch & Co <MER.N>, the world's largest brokerage. Merrill shares fell 1.3 percent to $32.26 before the opening bell.
A positive note was a jump of more than 8 percent in shares of H&R Block <HRB.N>, the biggest U.S. tax preparer, before the open. Block posted quarterly earnings above forecasts, aided by a weak dollar, which helped boost revenue from overseas.
On global markets, oil rose more than $3 a barrel, hitting a high of $143.54, propelled by a threat from Iran's Revolutionary Guards to impose controls on a vital waterway for much of the Mideast crude's exports.
The rise in oil of more than 40 percent so far this year has meant steady pressure on U.S. companies' profit margins.
"Higher oil suggests the trend we had last week in which we have higher energy costs and weaker everything else," said Rick Meckler, president of investment firm LibertyView Capital Management, Jersey City, New Jersey.
"It just means lower profit margins for companies which use oil and, more importantly, a weak consumer who spends more on filling up the tanks and less on other consumer items."
S&P 500 futures <SPc1> were 1.5 points higher, above fair value, a mathematical formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract.
Dow Jones industrial average futures <DJc1> slipped 19 points, and Nasdaq 100 <NDc1> futures fell 5.75 points.
Bove, an analyst at Ladenburg Thalmann, said he expected a 2008 loss by Merrill of $1.64 a share, compared with a prior view of profit.
The S&P 500 and Nasdaq indexes were on track to post their steepest first-half declines falls since 2002.
In the retail sector, UBS raised the price target of Wal-Mart <WMT.N>, the world's No. 1 retailer, and of BJ's Wholesale Club Inc <BJ.N>, the No. 3 warehouse club operator. But UBS cut rival Target Corp's <TGT.N> price target.
The downturn in New York City business continued in June after a brief pause in May, but reduced concerns about the credit crunch may have contributed to a more upbeat outlook, according to data from the National Association of Purchasing Management-New York.
