* Steel oversupply in China weighs on prices
* Steel demand may not recover until Q3, early Q4 - trader
* Spot iron ore at one-month low
(Updates rebar price)

SINGAPORE, July 16 (Reuters) - China steel futures dropped more than 1 percent to a contract low on Monday as plentiful supply pressures prices in the world's biggest steel market, where demand is not likely to recover until later in the year.
The decline in Shanghai rebar prices bucked gains elsewhere amid worries China's efforts to stimulate its economy – which grew at its slowest pace in three years in the second quarter -- may not quickly translate to firm demand.
The most-traded rebar contract for January delivery on the Shanghai Futures Exchange hit a session trough of 3,882 yuan ($610) per tonne, before closing down 1.3 percent at 3,889 yuan.
Shanghai rebar lost more than 3 percent last week, the steepest weekly drop since mid-May.
In the spot market, traders said the price of steel billet in China's key Tangshan area fell by 60 yuan to 3,510 yuan per tonne, moving closer to this year's low of 3,490 yuan.
"Crude steel production remains near an all-time high, so oversupply is going to continue for the sake of political stability and employment, thus steel prices will continue to fall," said a trader in Hong Kong.
China's average daily crude steel output hit 2.007 million tonnes in June, the second-highest level on record, as mills shrugged off slowing economic growth to maximise market share.
China on Friday reported that its economy slowed for a sixth successive quarter in April-June, with gross domestic product rising 7.6 percent year on year, matching market expectations.
The in-line growth, which calmed fears about a hard landing in China and boosted expectations Beijing will employ more stimulus measures, lifted Asian shares, although some commodities edged lower after a relief rally on Friday.
"Steel demand may recover but the effect of any policy move will have a lag time. So probably the earliest will be end Q3 or early Q4. There was oversupply in Q2, so stocks need to be cleared," the Hong Kong trader said.
The weakness in steel prices curbed demand for spot iron ore cargoes, as bids remained scarce.
Price offers for imported iron ore cargoes in China were steady on Monday. Benchmark iron ore with 62 percent iron content .IO62-CNI=SI dropped 0.7 percent to $132.80 per tonne on Friday, the lowest since June 11, based on data from Steel Index.
"Most mills prefer to get additional iron ore supply from stockpiles at ports. Many are still hand to mouth so they just buy what they need and wait what happens next," said an iron ore trader in Shanghai.
Miners continue to sell cargoes on spot, with top iron ore producer Vale SA offering 145,562 tonnes of 64.06-percent grade Brazilian iron ore at a tender closing later on Monday, traders said.
