* HK->Shanghai Connect daily quota used -5.2%, Shanghai->HK daily quota used -3.6% * HSI -3.6%, HSCE -4.0%, CSI300 -2.4% * FTSE China A50 -2.7% Feb 26 (Reuters) - Hong Kong stocks ended sharply lower on Friday, in line with broader markets, posting their worst week in one year, as a rout in global bonds sent yields flying and dampened appetite for risky assets. ** The Hang Seng index fell 3.6% to 28,980.21, while the China Enterprises Index lost 4.0% to 11,247.21 points. ** For the week, HSI tumbled 5.4%, while HSCE slumped 7.1%, both logging their steepest drops since the week to March 13, 2020. ** Yields on the 10-year Treasury note eased back to 1.494% from a one-year high of 1.614%, but were still up 40 basis points for the month in their biggest move since 2016. ** Adding to the pressure were worries over Sino-U.S. trade relations. ** Katherine Tai, President Joe Biden’s top trade nominee, backed tariffs as a “legitimate tool” to counter China’s state-driven economic model and vowed to hold Beijing to its prior commitments. ** This week’s retreat also came after a stamp duty hike that hit sentiment hard and deterred southbound funds. ** The stamp duty will rise to 0.13% of the value of the transaction from the current 0.1% on Aug. 1, Hong Kong Financial Secretary Paul Chan announced in his annual budget speech. ** “It’s an asset class type rotation now that you really looking at, because there’s nothing that’s impervious to the sell-off,” said Andy Maynard, head of equities at China Renaissance in Hong Kong. ** “Southbound (money) is cautious now. The day before yesterday was record selling for them and where they haven’t had a sale day since 2021 started. So, you got to feel that we are probably in the crosshairs of complete or a healthy correction”, he added. ** Mainland investors sold a net HK$3.1 billion ($399.68 million) of Hong Kong shares via the Stock Connect on Friday, according to Refinitiv data, following a daily record outflow of HK$20 billion on Wednesday.
