An article in the Wall Street Journal, March 10 2024, titled “Two Canals, Two Big Problems – One Global Shipping Mess” describes the logistics impact of low water levels in the Panama Canal and the Houthi rebel attacks on ships going through the Suez Canal. Drought in Panama has described daily ship traffic through the Panama Canal from 36 ships down to a projected 18 in February, with prices beyond a $0.5  million fee per ship crossing. Houthi attacks in the Gulf of Aden have caused ships to sail around the Cape of Good Hope, adding 10 days to trip times and doubling rates from those in 2023. Should shippers carry more inventory? Should shipping by air now be optimal for items such as apparel? When should consumer prices be increased to reflect these costs?
