NEW YORK, April 15 (Reuters) - Gold rose 1 percent to a record and silver soared on Friday, as inflation worries amid a crude oil rally and a downgrade of Ireland's sovereign debt powered bullion toward its fifth consecutive weekly gain.
Silver rose to its highest in 31 years on speculative buying and tight supplies, and as data showing rising U.S. consumer prices prompted investors to buy precious metals. Silver's outperformance over bullion also sent the gold/silver ratio below 34 for the first time in nearly 30 years.
"People are buying gold and silver as a protection against inflation. If the Fed doesn't start raising rates, inflation is really going to hit hard and cripple the economy," said Miguel Perez-Santalla, vice president of sales at Heraeus Precious Metals Management.
Spot gold <XAU=> rose 0.8 percent to $1,484.10 an ounce by 12:39 p.m. EDT (1639 GMT), having hit a record $1,487.39. U.S. gold futures for June delivery <GCM1> rose $12.40 to $1,484.80.
Silver <XAG=> gained 1 percent to $42.51. The gold-to-silver ratio -- showing the relative strength between the two metals -- fell to its lowest since the early 1980s.
The small rise in U.S. core inflation, and data showing moderation in long-term inflation expectations may be seen as vindication for Federal Reserve officials who have viewed the recent energy price spike as having a temporary effect.
"The Fed is not going to see inflation as a threat so they have the freedom to keep interest rates low longer," said David Wyss, chief economist at Standard and Poor's in New York.
Gold prices have almost doubled since the Fed cut interest rates to the bone in 2008 in an attempt to shock the economy back to life after the worst financial crisis since the Great Depression.
Gold also drew support from safe-haven bids on worries over the euro zone financial crisis, after more talk that Greece may be set to restructure its debt and a Moody's downgrade of Ireland. [
]"The market has been reacting to (the credit issues in peripheral Europe) by looking for ways to protect themselves from these types of risks, and gold is seen as a way to do that," Deutsche Bank analyst Daniel Brebner said.
Brebner said gold would benefit if there were another bailout in Europe and if European Union monetary policy remained accommodative because of fiscal troubles in the bloc.
Among other commodities, U.S. crude oil rose for a third straight day, as improving consumer confidence and industrial production boosted the outlook for oil demand. [
]Gold largely ignored news Goldman Sachs had recommended investors go underweight commodities over a three- to six-month horizon, echoing its call from Monday, saying oil prices were higher than justified by current supply and demand. [
]Among other precious metals, platinum <XPT=> eased 25 cents at $1,786.24 an ounce, while palladium <XPD=> gained 0.6 percent to $765.22. Prices at 12:39 p.m. EDT (1639 GMT)
