Indian gold consumption is expected to be 900-1,000 tonne in 2014 on strong jewellery and investment purchases, according to the WGC, still slightly behind top buyer China, whose demand is expected to be 1,000-1,100 tonne.
Bullion demand in India rose 13% last year to 974.8 tonne, according to the WGC's quarterly report issued on Tuesday, in a sign that consumer appetite has been largely unaffected despite restrictions on gold imports.
Struggling with an unprecedented high trade deficit and a plunging rupee, India was forced to impose curbs on gold - the second-biggest expense in its import bill.
A record high import duty of 10% and a rule tying import quantities to exports have crimped supply in what was until a year ago the world's biggest bullion consumer, prompting a sharp jump in smuggling.
"Despite all the curbs, demand has come in at 975 tonne. The question obviously is where the supplies came from," said Somasundaram PR, the WGC's managing director for India. "We have seen anecdotal evidence of smuggling. Our estimate is 150-200 tonne, more towards the upper end."
Smuggling could have been even higher as Indian gold imports have sagged in recent months to 20-30 tonne a month, compared with the record 162 tonne in May. Scrap gold is also being used to meet demand.
India's official gold imports in the first 11 months of 2013 totaled about 655 tonne.
"If supply restrictions continue, then we will see a much higher figure for smuggling," Somasundaram said, declining to provide an estimate.
Indian gold smugglers are adopting the methods of drug couriers to sidestep the government curbs, stashing gold in imported vehicles and even using mules who swallow nuggets to try to get them past airport security.
Customs officials have said though the number of seizures they have made has increased, they have been able to catch only a fraction of the illegal shipments into the country.
The Indian finance ministry and the central bank have acknowledged that smuggling has increased considerably but have said they will not ease the rules until they have a better grip on the trade deficit.
"All pointers are towards some kind of relaxation," said Somasundaram. "One possibility is that they will wait for the current account deficit figure till March end. The next possibility is that they may wait till elections (in May) but our expectation is that it will happen sometime before."
Reducing the import duty alone will not be enough to ease supply constraints, the WGC executive said. Easing of the central bank's 80/20 rule, which requires a fifth of all imports to be re-exported, will have more of an impact, he added.
Global gold demand fell 15% in 2013 as huge outflows from physically backed investment funds outweighed record consumer demand, London-headquartered WGC said in the report.
In contrast to India, top buyer China will likely introduce more reforms to make it easier for consumers to access gold in the growing market, said Albert Cheng, WGC's head of the far east region.
China made a string of changes last year, granting approval to its first gold-backed exchange traded funds and import licences to foreign banks for the first time.
"It is a measure to make sure that there are more suppliers. I think there will be a further opening up of the market," Cheng said, though he didn't elaborate.
Chinese demand in 2013 - which soared 32% to 1,065.8 tonnes last year - was supported by significant growth in both manufacturing and retail network capacity and that will continue this year, Cheng said.
