I have not seen any news mention of the Baltic Dry Index, a world wide shipping indicator that is claimed to be a leading indicator of economic activity swings.
“The Baltic Dry Index is an index that tracks the price of transporting dry bulk cargo like cement, coal, iron ore, and grain on bulk freighters. As many of these commodities are raw materials that go into production of finished goods, the BDI is often taken to be an indicator of economic growth and production. The index is maintained by the London-based Baltic Exchange.” This is quoted from Nasdaq.com.
I usually see it being discussed somewhere here when the world economy is about to drop significantly. Kind of watching for it lately. FWIW.
