* FTSEurofirst 300 index falls 0.96 pct
* HSBC falls after results, hurts other financial stocks
* Mining stocks decline as base and precious prices ease

LONDON, Aug 4 (Reuters) - European shares fell for a third straight day on Monday, as results from HSBC <HSBA.L> hit financial stocks and a broad-based decline in metal prices dented the mining sector.
Shares in HSBC -- Europe's biggest bank -- were among the largest individual drags on the European market, falling 1.4 percent after it said its first-half profit fell 28 percent, in line with forecasts. A $14 billion hit on bad debts on U.S. home loans and asset writedowns offset strong Asian growth.
The FTSEurofirst 300 index <
> fell 0.96 percent to 1,152.55 points, although activity was light, with 63 percent of the 30-day daily average volume changing hands.With three major central bank decisions due this week, along with a raft of earnings including Royal Bank of Scotland <RBS.L>, French banks Societe Generale <SOGN.PA> and BNP Paribas <BNPP.PA> and reinsurers Swiss Re <RUKN.VX> and Munich Re <MUVGn.DE>, intraday volatility in the FTSEurofirst was at its lowest in a month.
"This is a massive week for markets, they're going to be pulled all over the place. I think the market will remain volatile and will react to individual pieces of corporate data and also there are big statements coming out. The Fed statement tomorrow will be absolutely vital in terms of market direction," said Henk Potts, a strategist at Barclays Stockbrokers.
The U.S. Federal Reserve, which releases its policy decision on Tuesday, the European Central Bank and the Bank of England, which deliver their verdicts on Thursday, are all expected to keep their respective interest rates unchanged.
But as economic growth in the three regions continues to lag and inflation shows no signs of cooling, investors will be on the lookout particularly for policymakers' thinking on the likely path of interest rates.
BANKS UNDER PRESSURE
Results from HSBC and the focus on interest rates kept bank stocks under pressure. Shares in BNP Paribas <BNPP.PA> were down 3.3 percent, while UBS <UBSN.VX> lost 4 percent and Spain's BBVA <BBVA.MC> fell 2.3 percent.
"HSBC today was a reasonable set of numbers. I think they've done well to expose themselves to the fast-growing emerging markets, but clearly it's showing you the problems in the U.S. continue, the credit crunch continues to bite and even for some of the more successful financial institutions it continues to take its toll," Potts said.
Belgian-Dutch group Fortis <FOR.AS> <FOR.BR> lost more than 3.2 percent after the company said writedowns had cut second-quarter net profit in half and shoring up a weak balance sheet was its top priority.
The DJStoxx index of European banks <.SX7P> is down 32 percent this year, while the FTSEurofirst, which fell for the third month in a row in July, has lost 23 percent so far.
Susanne Lahmann, equity strategist at Bremer Landesbank, said the modest rise in European stock markets over the past two weeks was unlikely to last.
"I can't see where impulses for a further recovery could come from," she said. "It is fairly quiet at the moment. I think this week will be driven mainly by news from the interest rate front," she said.
Around Europe, Britain's FTSE 100 index <
> fell 0.6 percent, Germany's DAX < > fell almost 0.7 percent and France's CAC 40 < > declined 0.8 percent.A drop in the price of copper <MCU3=LX> to four-month lows and spot platinum <XPT=> hitting six-month lows weighed on the mining sector. Rio Tinto <RIO.L>, Xstrata <XTA.L> and Anglo American <AAL.L> fell between 4.5 and 6 percent.
The sell-off in commodities extended to crude oil <CLc1> which fell below $120 a barrel for the first time since early May in the closing moments of trade on the European equities market.
BP <BP.L> lost 0.6 percent, Norwegian oil and gas group StatoilHydro <STL.OL> rose 0.5 percent and France's Total <TOTF.PA> lost 1.1 percent. (Additional reporting by Eva Kuehnen in Frankfurt; Editing by Erica Billingham)
