In an interview, Tavi Costa, portfolio manager at Crescat, said his favorite commodity is silver because of its dual benefits: monetary and industrial. He claims that it will shoot up soon, thanks to governments' new green programs.

To be more specific, since silver is needed to develop green technologies, demand for the commodity will soar, which will push prices up.

Costa is also bullish on other commodities such as gold, copper and tin. He said any long position in them is a better investment than common stocks, because any drop will be bought back soon.

Gold and silver will also have an edge over other commodities since investors are going to focus on protecting their money amid rising inflation and low interest rates.

Costa claims that central bank officials are underestimating inflationary pressures, divulging that there are signs indicating that inflation may persist much longer than expected.

For example, if wages of US workers increase, consumer demand is likely to jump as well, which will trigger inflation.

The only thing that can change the situation is a serious correction in the stock markets, but this could result in deflation.

For now, investors have to deal with the looming threat of inflation and the Federal Reserve's insistence on historically low interest rates. And along with keeping interest rates low, Costa said the Fed will maintain its bond purchase program because it provides stability in the financial markets.
