Dalian iron ore sank deeper on Thursday, while benchmark prices of the steelmaking ingredient in Singapore hovered near 2022 lows, hammered by a gloomy outlook for global steel demand and supply-side pressures.

Steel prices in China, which accounts for about half the world's output of the construction and manufacturing material, also fell amid a worsening COVID-19 situation in Beijing.

The most-traded January iron ore on China's Dalian Commodity Exchange DCIOcv1 ended morning trade 2.5% lower at 670.50 yuan ($92.58) a tonne, after touching its weakest since Sept. 5 at 670 yuan.

On the Singapore Exchange, the benchmark November iron ore SZZFX2 contract was down 1.5% at $90.65 a tonne by 0348 GMT, near its 2022 low of $90.30 hit on Tuesday.

The World Steel Association now expects a 2.3% contraction in global steel demand this year, revising its forecast from a 0.4% growth.

The Brussels-based group said the global economic environment has deteriorated significantly, citing high inflation and interest rate hikes, and China's slowdown due to its zero-COVID policy and property sector downturn.

"The slump in the property market has deepened, with investment in real estate slowing to its worst in 30 years," the group said in a report on Wednesday.

"Despite the government's efforts to boost the real estate market, a major turnaround is not expected since buyers' confidence remains weak due to strict COVID-19 measures and developer bankruptcies."

Supply-side pressures intensified. This week major miners BHP Group (BHP) and Vale SA VALE3.SA reported higher quarterly iron ore production, while Rio Tinto (RIO) RIO.L posted a 4% quarter-on-quarter rise in shipments.

Rebar on the Shanghai Futures Exchange SRBcv1 fell 1.2%, hot-rolled coil SHHCcv1 dipped 0.9%, wire rod SWRcv1 shed 0.5%, while stainless steel SHSScv1 rose 1.6%.

Other steelmaking inputs also dropped, with Dalian coking coal DJMcv1 and coke DCJcv1 down 1.7% and 2.2%, respectively.
