July 8 (Reuters) - Dalian iron ore prices jumped on Friday, underpinned by renewed hopes for additional infrastructure spending by China, but futures in Singapore slipped on demand worries due to COVID-19 lockdowns in the world top steel producer.
The most-traded iron ore, for September delivery, on China's Dalian Commodity Exchange DCIOcv1 rose as much as 4.2% to 782 yuan ($116.72) a tonne, its highest since July 1.
On the Singapore Exchange, however, the steelmaking ingredient's front-month August contract SZZFQ2 was down 0.7% at $112.80 a tonne, as of 0244 GMT, set to post its fourth weekly loss in five weeks.
In the spot market, iron ore prices were also set for weekly declines, with the benchmark 62%-grade material bound for China having been assessed by SteelHome consultancy at $114 a tonne on Thursday, down 3% from last week. SH-CCN-IRNOR62
China's Ministry of Finance was considering allowing local governments to sell 1.5 trillion yuan ($220 billion) of special bonds in the second half of this year to boost infrastructure funding aimed at supporting the struggling domestic economy, Bloomberg News reported.
