ISTANBUL, Dec 10 (Reuters) - Turkish shares eased in line with other emerging markets on Friday, but the lira and bonds were flat and dealers said markets were holding up despite a lower than expected figure for third quarter growth.

Growth came in at 5.5 percent year-on-year compared with consensus expectations for a 6.6 percent expansion. The lira eased slightly to 1.5015 against the dollar after the data, compared to around 1.5 immediately before and 1.5010 on Thursday.

"We don't think (the data) will have much of an impact on financial markets because although the headline figure was below expectations the details were positive," said HSBC Istanbul-based strategist Fatih Keresteci.

"As we do not think it will change the Central Bank's policy stance, we take the view that it will not have a significant impact on secondary market interest rates," he said.

The yield on Turkey's benchmark bond <0#TRTSYSUM=IS> edged up to 7.67 percent from 7.66 percent before the GDP data's release and compared with 7.65 percent on Thursday.

Economists noted that the growth was import-driven, exports remained weak, while investment spending picked up.

"We are thus going to see whole year GDP growth at around 7.5-8 percent. Nice, but again the one problem Turkish equities have (is) namely dealing with high base effects from 2010," said Simon Quijano-Evans, economist at C.A. Cheuvreux, based in Vienna.

Istanbul's main share index <.XU100> was down 0.28 percent to 65,728 points, having been down 0.51 percent beforehand. The index, which has surged by more than a quarter this year, had dropped 2.64 percent on Thursday.

It slightly underperformed the MSCI emerging markets index <.MSCIEF>, which dipped 0.17 percent.

Shares were led lower by banks on concerns about lower sector profits next year, with the banking index <.XBANK> down 0.51 percent after a slide of more than 4 percent on Thursday.

The banking regulator this week said the sector's profits in 2011 would be lower than this year, and that it would prefer banks to conserve strength and not pay dividends this year.

Most actively traded Garanti Bank was 0.71 percent lower at 8.36 lira.

Isbank was down 0.7 percent after it said it had applied to Turkey's banking regulator for permission to issue up to 5 billion lira worth of lira-denominated corporate bonds. (Writing by Daren Butler; Editing by Simon Cameron-Moore)
