The level of GDP is what matters for commodities

This chart highlights that commodity prices are more sensitive to the level of GDP than the growth rate.
The shaded regions refer to periods during which the G20 Composite Leading Indicator (CLI) is above 100. This indicator is designed to capture fluctuations in economic activity around its long-term potential level and provide a six-to-nine-month lead on business cycle turning points. A value above (below) 100 corresponds with expectations that the level of GDP will be above (below) its long-term trend. Meanwhile, a rising (falling) CLI implies that GDP growth is anticipated to accelerate above (decelerate below) long-term trend growth.
The chart reveals that energy and industrial metal prices typically rise on a year-over-year basis when the level of GDP is expected to be above its long-term trend, regardless of whether the CLI is rising or declining. This result is intuitive given that, ceteris paribus, an above-trend GDP level likely corresponds with an above-trend level of commodity consumption.
Moreover, prices of these commodities generally decline during periods when the CLI is below 100, regardless of whether the CLI is rising or declining. This implies that commodity prices typically fall on a year-over-year basis when the level of GDP is expected to be below its long-term trend. Again, this result makes sense given that a below-trend level of GDP implies that the level of commodity consumption is also relatively weak.
