Gold ETFs continue to rise as the precious metal touched $1,700 an ounce on Tuesday to its highest level in about six months on speculation central banks will announce more easing measures to support the global economy.

Investors are using ETFs to position for higher gold prices.

“Investors hold more gold through exchange traded funds than at any time in the past, after hefty inflows of metal into these products in August,” Reuters reports.

Last week, Fed Chairman Bernanke’s concern over the country’s unemployment level hinted at further accommodative measures, lifting gold exchange traded funds on the higher inflation outlook and pressuring the U.S. dollar assets.

Meanwhile, the PowerShares DB US Dollar Index Bullish (NYSEArca: UUP) dipped 0.6% as any policy stimulus would depreciate the value of the U.S. dollar.

“As we assess the benefits and costs of alternative policy approaches … we must not lose sight of the daunting economic challenges that confront our nation,” Bernanke stated at the Kansas City Fed’s annual Jackson Hole symposium, Reuters reports.

Specifically, Bernanke highlighted the nation’s employment numbers.

“The stagnation of the labor market in particular is a grave concern not only because of the enormous suffering and waste of human talent it entails, but also because persistently high levels of unemployment will wreak structural damage on our economy that could last for many years,” Bernanke added.

“Bernanke has laid the groundwork for taking future action should it be needed—whether any additional action will make a difference is an open-ended question,” Michael Sheldon, chief market strategist at RDM Financial Group, said in a CNBC report. “However, the fact the Fed remains open has probably provided a floor for markets.”

If the Fed were to implement further action, we may see an additional quantitative easing plan (QE3), another operation twist where interest on long-term debt is artificially lowered or interest rates could be extended to beyond 2013.

However, Abigail Doolittle for Peak Theories Research argues that we may not see another quantitative easing plan until we experience steep deflationary pressures since it can not be easily remedied with a simple interest rate hike or drop.

“It would seem more appropriate to keep that controversial policy option on the shelf until it is needed as it may sure be needed considering the slide in global growth and the continued pressures of deleveraging,” Doolittle said.

In Europe, investors were looking for more bond buying from the European Central Bank, which meets later this week. “ECB President Mario Draghi indicated late Monday that bond purchases with maturities of up to three years would not violate the bank’s mandate,” MarketWatch reported.
