MANILA, April 19 (Reuters) - Chinese iron ore futures dropped nearly 2 percent on Wednesday, extending losses for a third day along with steel prices amid concerns supply was outpacing demand in the world's top steel producer and consumer.
But the declines for steel and iron ore were smaller than in recent sessions even as both commodities touched multi-month lows. Coking coal dropped more than 4 percent after lagging earlier losses in steel and iron ore.
"It's still because of sufficient supply and relatively slow demand," said Richard Lu from CRU consultancy in Beijing, on the sustained drop in steel prices.
"Prices are converging to what's justified by supply-demand fundamentals. Market sentiment is very bearish."
The most-traded iron ore on the Dalian Commodity Exchange was down 1.7 percent at 474 yuan ($69) a tonne by midday break. The contract fell as far as 467 yuan, near Tuesday's three-month low when it tumbled 6.5 percent.
On the Shanghai Futures Exchange, the most-active rebar was down 1.1 percent at 2,838 yuan per tonne, off a 10-week low of 2,811 yuan reached earlier in the session. The construction steel product fell 3.7 percent on Tuesday.
China's crude steel output reached a record 72 million tonnes in March as mills ramped up output in anticipation of a pickup in demand that has remained slow, government data released on Monday showed.
Leaner steel demand has curbed appetite for iron ore with spot prices extending their descent.
Iron ore for delivery to China's Qingdao port .IO62-CNO=MB fell 4.6 percent to $63.20 a tonne on Tuesday, the lowest since October 2016, according to Metal Bulletin.
The spot benchmark has lost nearly 20 percent this year after an 81-percent rally in 2016.
Coal used in steelmaking fell more deeply on Wednesday after having lagged the declines in steel and iron ore futures. Dalian coking coal was down 4.5 percent 1,062 yuan a tonne and coke slid 5.3 percent to 1,545 yuan. ($1 = 6.8830 Chinese yuan) (Reporting by Manolo Serapio Jr.; Editing by Tom Hogue)
