South Korea's first gold purchase since the Asian financial crisis shows that the official appetite for gold remains intact in the face of record prices, as a shaky global economic recovery, sovereign debt issues and high inflation drive diversification.
South Korea may be followed by other central banks in the region as worries about US debt payments and euro zone sovereign default dent the appeal of the world's top two currencies for holders of trillions of dollars in foreign exchange reserves.
The Bank of Korea bought 25 tonnes of gold worth USD 1.24 billion in the last two months, increasing its holdings to 39.4 tonnes, still well below other Asian countries such as China, India and Japan.
It follows in the footsteps of India and China, which made major purchases in 2009, and most recently Thailand.
Despite the purchases, gold still makes up only a tiny fraction of reserves for most of these fast-growing Asian economies -- as little as 1.6% in the case of China.
"As the foreign exchange reserves of emerging economies increase with rapid economic growth, the proportion of gold in their portfolio is correspondingly reduced," said Ong Yi Ling, investment analyst at Phillip Futures.
"Central banks have become more friendly towards gold after the financial crisis. Western central banks now have a reduced appetite for gold sales. In 2010, the official sector became a net buyer of gold for the first time in 21 years."
Earlier this year, Thailand, whose gold holdings account for only 2.9% of reserves, bought 9.3 tonnes of gold. Russia purchased 41.8 tonnes and Mexico bought 99.2 tonnes before selling some, according to the World Gold Council.
China is the world's sixth largest gold holder and the biggest among Asian banks with 1,054.1 tonnes, equivalent to 1.6% of its reserves.
The Bank of Korea said gold looked less lucrative as an investment as it hovers near all time highs, but it was the right time to buy the precious metal because its foreign reserves had risen above USD 300 billion.
Cash gold was little moved after South Korea's announcement of the purchase, but held near a record around USD 1,632 an ounce hit last week.
"I believe the concept that gold continues to be viewed as a safe haven asset, and a vehicle to diversify portfolios by large central banks speaks volumes," said David Meger, director of metals trading at Vision Financial Markets.
"Given the dark cloud of European and domestic debt issues, sagging economic activity, weak unemployment, and the threat of potential credit downgrades, we continue to believe that gold will be fundamentally supported for years to come."
An 11th hour deal to raise the US debt ceiling cleared its biggest hurdle in the House of Representatives and staved off the prospect of a calamitous default, but it failed to allay fears Washington could still lose its triple-A credit rating.
The U.S. dollar tumbled to a record low around 0.7730 against the safe-haven Swiss franc on Monday, while the euro was at 1.1173 francs , not far off a record low near 1.1025.
"As the U.S. has printed lots of cash and may print more, the only way to protect value is to buy commodities to hedge against inflation," said Peter Fung, head of dealing at Wing Fung Precious Metals in Hong Kong.
The United States' debt woes still threaten the global economy despite the last-minute deal struck by the White House and political party leaders, China's main official newspaper said on Tuesday.
Beijing, the largest creditor to the United States, has repeatedly urged Washington to protect its dollar investments, estimated to account for about 70 percent of its $3.2 trillion in foreign exchange reserves, the world's largest.
Will China be another big buyer again, having made a major purchase in 2009?
"With gold representing only about 2% of its foreign exchange reserves, some are speculating that China may acquire more gold from their domestic mines in the future," said Ong of Phillip Futures.
"However, the size of the gold market is still extremely small compared to the FX market. Gold cannot be a main channel for the investing of foreign exchange reserves."
