LONDON, Aug 10 (Reuters) - Anxiety over emerging market assets sent Britain's FTSE 100 down on Friday as a currency crisis in Turkey deepened and Russia's rouble extended losses, dragging exposed stocks down.
The index .FTSE fell 1 percent, though it outperformed Europe's STOXX 600 and Germany's DAX, which dropped 2.1 percent.
The FTSE 100 fell despite a slide in sterling, which usually supports the exporter-heavy index. The negative relationship between the two has evaporated recently. https://reut.rs/2OkPhOi
Many UK-listed companies derive a significant chunk of revenues from emerging markets, and several Russian companies are listed on the British stock market.
Russian gold miner Evraz EVRE.L was the worst-performing FTSE 100 stock, down 8.8 percent after broker VTB Capital downgraded it and the rouble fell to its lowest since July 2016 on anxiety over a fresh round of U.S. sanctions. miners Polymetal POLYP.L and Kaz Minerals KAZ.L fell 2.4 and 1.4 percent.
Smaller UK-listed stocks exposed to Turkey and nearby emerging markets were also bruised.
DP Eurasia DPEU.L , a franchisee of Domino's Pizza DOM.L which generates 68 percent of sales in Turkey, sank 14.4 percent to the bottom of the small-caps index .FTSC .
Travel operators On The Beach OTB.L and Thomas Cook (NS:THOM) TCG.L , which sell package holidays to Turkey, fell 4.1 percent and 1.9 percent respectively.
Georgian lenders TBC Bank TBCG.L brought up the rear on the FTSE 250, down 3.7 percent as the Georgian lari GEL= sold off.
Emerging markets-focused asset manager Ashmore ASHM.L tumbled 3.7 percent.
The Turkish lira's slide to record lows, as President Tayyip Erdogan dismissed investors' concerns, sent tremors across other emerging markets, with South Africa's rand falling to a six-week low. weighed on South Africa-exposed bank Investec INVP.L , whose shares fell 3 percent. Packaging firm Mondi MNDI.L and miner Anglo American AAL.L , also founded in South Africa, tumbled 2.3 and 2.6 percent.
Emerging markets-focused lender Standard Chartered STAN.L fell 1.9 percent.
"Whilst generally EM economies are much stronger than they were 20 or 30 years ago you've still got some countries that are a bit of a mess," said Peter Elston, chief investment officer at Seneca Investment Managers.
"That's occasionally going to cause problems for the asset class as a whole, as it is doing at the moment."
Miners were a big weight on the FTSE 100, with Anglo American and Glencore GLEN.L falling 2.5 percent and 2.7 percent as copper prices fell on a stronger dollar. EM-driven moves, shares in engine maker Rolls-Royce RR.L fell 3.7 percent after JP Morgan downgraded the stock to "underweight".
"Relative to other civil aerospace stocks we follow, we think Rolls-Royce now offers investors a less attractive risk-reward," JPM analysts wrote, arguing the firm is showing deteriorating earnings quality.
The FTSE 250 .FTMC fell less sharply, down 0.7 percent thanks to its less internationally exposed constituents.
"Mid-caps fell horribly following the (Brexit) vote, and they've since made back everything they've lost and more, which suggests they have been able to thrive in this post-ref vote environment," said Seneca's Elston.
However, he added, "earnings have been very mixed."
Analysts have been cautious on mid-cap earnings, while the index has been declining since a record high hit on June 14.
