Silver and Gold at a new all-time high

When Jean-Claude Trichet reported a quarter-point increase at the benchmark interest rate in Euro Area, gold and silver price reached a new all-time high - silver pushed above $40 a troy ounce for the first time since 1980 and gold to $1474,19. Why did this happen?
Gold and Silver are well known among investor as the safe haven to curb inflation efects. So when the European Central Bank President announced the increase, investors got concerned about the inflation and migrated to those assets.

Country	Interest Rate	Growth Rate	Inflation Rate	Jobless Rate	Government Budget	Exchange Rate
Euro Area	1.25%	0.30%	2.60%	9.90%	-6.30	14200

Furthermmore, the hike on those commodities price this week has also to do with the potencial shutdown of the US Government due to some divergences between Republicans and Democrats. The deal was to cut $100 billion in fiscal spending in 2011 BUT the agreement cuts $39 billion in atual spending, which is $22 billion less than bill the House passed in Feb by President Obama's fiscal 2011 budget request - $78.5 billion.
Analysts and investors now see $1,500 gold and $50 silver as likely to be breached in the coming months, as the potential for looser monetary policy for longer in the US weighs on the dollar. Why?
Commodities are usually priced in dollar, so a weaken dollar boosts raw materials prices and can valorize other currencies such as Real, the Brazilian Currency and the Euro.
