Exchange traded funds (ETFs) that invest in gold and silver jumped Monday morning after Standard & Poor’s cut its outlook on U.S. debt to negative, while Treasury ETFs fell in the wake of the downgrade.

The iShares Silver Trust (NYSEArca: SLV) rose more than 1% in early trading while SPDR Gold Shares (NYSEArca: GLD) was up fractionally. Both ETFs notched fresh 52-week highs in early action.

Meanwhile, ETFs that track U.S. Treasury bonds weakened after S&P said it sees a 1-in-3 chance it could lower its long-term rating on the U.S. in the near term.

The iShares Barclays 20+ Year Treasury Bond Fund (NYSEArca: TLT), which follows the long end of the yield curve, fell about 1%.

In U.S. stocks, SPDR S&P 500 ETF (NYSEArca: SPY) dropped more than 1% in recent trading.

However, the dollar strengthened against a basket of foreign currencies as PowerShares DB US Dollar Bullish Fund (NYSEArca: UUP) traded higher after the S&P bombshell.
