NEW YORK (Reuters) - Gold rose 1 percent on Tuesday as volatility in the currency market triggered by Japan's aggressive monetary easing plan lifted bullion's appeal as a hedge against inflation and currency fluctuations.
Silver, often more volatile and speculative than gold, rose nearly 3 percent and was on track to post its biggest one-day gain since September.
Bullion climbed to a one-week high as the dollar fell against the euro and the yen, with the Japanese currency recovering from a four-year low set against the greenback earlier in the session.
Gold had largely failed to rally after the Bank of Japan pledged last Thursday to inject about $1.4 trillion into the economy over two years. The metal ended the week down 1 percent.
"Gold is now slowly sinking in to the news that Japan is printing a quick deal of money and liquidity is going to be abundant again," said Axel Merk, chief investment officer of Merk Funds, which oversees $630 million in mutual fund assets.
