Optimist in regards to commodity prices, Goldman Sachs Group Inc., do not lose its mood amid falling prices and forecasts raw materials returns at 17% in next months, Bloomberg reports.

The turning moment for commodities markets the company sees in coming G-20 summit in Argentina, as it may eliminate many concerns in regards to some fundamental market drivers, including production cuts by OPEC and improvement in relations between the US and China.

Commodities were under hit in November due to a whole row of factors: oil price falls amid concerns about supply, metals lose value due to slower growth, while investors do not trust the market because of escalating conflict between China and US.

Goldman expects that OPEC’s production cuts will initiate recovery of oil prices.

The probability of US interest rates hike is very high. In case of slower economic growth in the US next year, gold will rise along with the demand for safe assets. Goldman also expects rising prices for soybeans after US-China trade talks.
