Commodities Surged Last Week, Leading The Major Asset Classes

 | Jul 15, 2019 07:27AM ET

Broadly defined commodities topped last week’s performance ledger for the major asset classes – by a wide margin, based on a set of exchange-traded funds. Most of the gain was linked to higher oil prices, which rose due to a perfect storm of several bullish factors last week.

The iShares S&P GSCI Commodity-Indexed Trust (NYSE:GSG) jumped 3.4% for the trading week through Friday, July 12. The rally lifted the fund to its highest close since late-May.

Several factors were behind the jump in commodity prices. A tropical storm that turned into a hurricane in the Gulf of Mexico triggered fears of a disruption in energy supplies in the region, which is critical for oil and gas production in the US. In addition, heightened geopolitical tensions between the US and Iran played a role in supporting energy prices. It didn’t hurt that last week’s June data on consumer inflation in the US posted slightly higher-than-expected results.

Last week’s weakest performer for the major asset classes: foreign stocks in developed markets. Vanguard FTSE Developed Markets (NYSE:VEA) fell 0.5%, marking the ETF’s first weekly decline in a month.

Meanwhile, an ETF-based version of Global Market Index (GMI.F) continued to edge higher. This unmanaged benchmark, which holds all the major asset classes (except cash) in market-value weights, rose 0.8% — the sixth consecutive weekly gain for GMI.F.
