Chinese lenders could face mounting short selling pressure on Friday after interim results from two leading banks -- Industrial & Commercial Bank of China and Bank of Communications -- deepened worries that the nation's lenders face a worsening debt problem. ICBC, the nation's No.1 lender by assets, which posted a 13 per cent net interim profit growth on Thursday after the market close, said "non-performing loans increased slightly in some industries and areas due to economic volatility". The non-performing loan (NPL) ratio for personal loans rose 0.64 per cent to 0.54 per cent. Its smaller peer BOCOM also said late on Thursday that loans overdue by more than three months, a key indicator of future asset quality, rose 10 per cent from the end of last year. Meanwhile, GOME ( 0493.HK ) and Yue Yuen Industrial (Holdings) ( 0551.HK ) are among a batch of companies due to report interim results later in the day. Overnight, the Standard & Poor's 500 Index lost 11.01 points to close at 1,399.48 as investors hugged the sidelines ahead of a key speech by Federal Reserve chairman Ben Bernanke to central bankers at their annual get-together in Jackson Hole later on Friday. The Dow Jones Industrial Average lost just over 0.8 per cent to end at 13,000.71. In London, the FTSE-100 Index fell 0.4 per cent to end at 5,719.45. Factors to watch: -- Airline firms' profit hit turbulence China Eastern Airlines Corporation ( 0670.HK ) said after the close on Thursday that first-half profit fell 65 per cent to 807 million yuan, dragged down by high fuel costs, a weak global aviation market and competition from domestic high-speed railways. Its peer Air China ( 0753.HK ) said this week that profit slumped 77 per cent during the period. -- Hong Kong unveils new measures to tame home prices After the market close on Thursday, Hong Kong Chief Executive CY Leung unveiled 10 measures to curb the city's overheated property market. Most of the measures involve increasing the supply of new flats to address rising demand in the short and medium term. Most analysts, however, said the measures are too weak to cool the housing market. Sino Land ( 0083.HK ) lost almost five per cent on Thursday and Sun Hung Kai ( 0016.HK ) closed down 3.6 per cent on Thursday even before Leung's announcement as investors locked in profit and cut exposures ahead of the Hong Kong government announcement of new policy measures. -- China sees declining iron ore production The association of mainland iron ore producer says output is likely to have dropped around 10 per cent this month from a year earlier, due to industry oversupply and sluggish demand amid slowing economic growth, according to a news report by RTHK on Thursday. -- China unveils new medical insurance scheme China on Thursday approved a proposal to allow its citizens to enjoy an additional special medical insurance scheme beside the existing general plan. The scheme would claim no less than 50 per cent of bills for some severe diseases to ease the public's financial burden, according to Shanghai Security News.
