Brent crude has broken back above $100 a barrel, up 42 percent in just 20 days, and the Kobeissi Letter says inflation expectations and interest rates are climbing sharply again as a result. The $100 level is a psychological line that traders and central banks watch closely, since oil feeds directly into the price of gasoline, shipping, and nearly everything else, so crossing it tends to move inflation forecasts more than the same percentage move at a lower price would. This latest leg up builds on a month of escalating headlines, Houthi forces striking Saudi tankers, Iran threatening energy infrastructure, and warnings that the Strait of Hormuz will not return to pre-war shipping conditions, each event adding its own premium on top of the last. The speed of the move matters as much as the level. A 42 percent rise in 20 days is the kind of shock that shows up in consumer prices within a quarter, and it arrives just as bond yields are already climbing on their own. If oil holds near $100, central banks that had been leaning toward cutting rates get a harder case to make, and companies that depend on fuel and shipping costs face a fresh squeeze even before the broader economic picture is clear.
Why it matters · A 42 percent oil spike in 20 days is fast enough to move inflation forecasts and rate-cut odds before the war's outcome is even known.
Worth asking · Iran war risk pushed Brent through $100 in three weeks. Does this become the inflation shock that talks the Fed out of further cuts, or does the war premium deflate as fast as it built once the shooting stops?
