* FTSE 100 down 0.2%, FTSE 250 flat

Aug 8 (Reuters) - London stocks opened lower on Tuesday hurt by the losses in Glencore after the miner's dour first-half earnings, while bleak China trade data also hit the broader mining sector.

The FTSE 100 index dipped 0.2% by 0709 GMT, with Glencore falling 3.0% as it said its earnings had halved in the first half.

The industrial metals and mining sector declined 1.9%, after data showed earlier in the day that top consumer China's imports and exports fell much faster than expected in July amid weaker demand.

Asset manager abrdn slipped 4.5% to the bottom of the FTSE 100 after it reported a drop in its assets under management.

The midcap FTSE 250 index was flat, while bank stocks shed 0.8%.

Global sentiment on banking soured after Moody's cut credit ratings of several small-to-mid-sized U.S. banks on Monday and said it might downgrade some of the nation's biggest lenders. (Reporting by Siddarth S and Shreyashi Sanyal in Bengaluru; Editing by Rashmi Aich)
