Since tradition demands a bride practically drip with gold jewelry, it’s never too early for an Indian family to start preparing, particularly with the high cost of gold these days.

“I’m collecting things for her now so when she grows older and marries, I should have enough gold for her,” said Rao. “It is very auspicious for us, one of the most auspicious things, to give gold to your daughter.”

Gold has been deeply entwined in Indian culture for thousands of years. Nowadays, India is by far the world’s biggest buyer of gold and those imports are an increasing drain on an economy that is growing too slowly to reduce widespread poverty. Last year Indians imported 864 tons of gold, about one fifth of world sales. The cost of 2.5 trillion rupees ($45 billion) was second only to India’s bill for imported oil. The unquenchable appetite for gold coins, bars and jewelry has swelled India’s trade deficit and weakened its currency, making crucial imports such as fuel more expensive.

The government can’t do much about oil imports — without fuel, the economy would grind to a halt — so in the past year it has tried to rein in gold demand, raising the import duty three times in a year to its current level of 6 percent. The higher tariff is proving little match for age-old tradition.

“Every Indian wants gold. Now is the wedding season, and I’m seeing an increase in demand no matter about the tax,” said jeweler Arun Kaigaonkar. “Prices have been rising for years, and still people buy.”

He said not only jewelry, but gold bars and coins remain in high demand because in many rural areas banking is less available. “In the countryside, people save their money only in gold.”

Last year Indian gold-buying briefly dropped for six months, but then it roared back in the second half of the year. And in January, sales spiked sharply as jewelers and investors rushed to buy ahead of the import tax hike to 6 percent, which took effect at the end of the month.

“The culture of gold is so strong in India. It’s difficult to contain this demand by just tweaking import duties,” said Samiran Chakraborty, an economist with Standard Chartered Bank in Mumbai.

Through centuries of warfare and the shifting borders of regional kingdoms, gold was the safest currency. In some Hindu legends, Brahma, the god who created the universe, was born from a gold egg. In India, gold is spiritual and it is also practical. Parents of the bride give gold as a symbol of their prosperity. But it is also insurance against a bad marriage, since the jewelry is the wife’s, though many men take it anyway.

In early 2011, an ounce of gold cost about $1,375 on the world market, or nearly 62,000 rupees inside Indiaat the exchange rate at the time.

It now costs over $1,600 an ounce but the drop in the rupee against the dollar means the cost in India has risen by an even greater extent, to about 90,000 rupees.

The rising price does reduce demand but each festival and wedding season brings sales back up again.

Industry experts say there are signs that higher import taxes have encouraged smuggling, which hasn’t been a problem since India lifted strict gold controls more than 20 years ago.

Few expect a return to those draconian measures. Potentially more effective is a new scheme to get the vast amounts of gold already in India back into circulation.

“India is not only the world’s biggest importer of gold, it’s the biggest hoarder of gold,” said Albert Cheng, a managing director of the World Gold Council, which estimates there are some 18,000 tons of gold locked up in bank vaults and family homes around the country.

Standard Chartered’s Chakraborty said such “non-productive” gold in India is worth some $1 trillion, about half of India’s GDP.

The government recently stopped requiring gold-backed exchange-traded funds to hold physical gold in the amount of their sales. Instead, the funds will be allowed to deposit some gold with banks who in turn can lend it to jewelers, which in theory should reduce imports for a time.

“Up to now, both jewelers and ETF’s have been driving the rise in import demand. Now, maybe they can start to cancel each other out,” Chakraborty said.

The funds have combined assets of about $1.8 billion, a small proportion of India’s gold purchases, so progress might be slow.

“Gold is considered pure in our culture, and giving it is a virtue. Certain amount of gold must be bought,” said 26-year-old Rohini, a Mumbai physiotherapist as she browsed in a jewelry shop.

Her mother, Jaishri, agreed. “Of course, nobody can afford as much as we used to. Once upon a time, we used to buy gold by the kilo,” she said. “But the price is so high now, we just buy what we can for the necessary things.”
