The outline of conditions and topics for a negotiated settlement of the U.S.-Iran conflict called a Memorandum of Understanding (MOU) and signed by both sides last week in all probability won't prevent the approaching energy cliff. That cliff will be the result of fast-depleting commercial and strategic inventories of oil and oil products around the world that have acted as buffers in the wake of the suspension of almost all tanker traffic through the Strait of Hormuz during the conflict—tankers believed to carry about 20 percent of the world's daily needs of oil.
As I explained in a previous piece, the world is fast approaching "tank bottoms," that is, the depletion of usable oil and oil products inventory. When that inventory effectively runs out, there will be a bidding war for oil and oil products to replace the millions of barrels per day that will still be needed but unavailable from inventories as the drama in the Persian Gulf continues.
As of this writing, the Strait of Hormuz has been closed by Iran in response to continuing attacks by Israeli armed forces in Lebanon. The first provision of the MOU is that hostilities are to cease immediately everywhere including Lebanon as a pre-condition to further negotiations. Just as important as whether the strait is open are what each side means by the word "open" and how shipping companies and the insurance firms who insure their tankers understand the risk of transiting the strait.
