| An oil-price spike delivers two hits to inflation. The first is quick and obvious: As gasoline and other fuel costs jump, so does total “headline” inflation. | | The second is slow and subtle. As costlier fuel works its way into other products and services, “core” inflation, which excludes food and energy, comes under upward pressure. | | Those latter “second-round” effects have been largely forgotten about in recent decades because “most of those oil shocks in the last 40 years tended to be fairly short lived,” says Morgan Stanley economist Michael Gapen. For example, roughly 200 days after Russia invaded Ukraine in 2022, oil was $7 below its preinvasion price. When companies don’t expect costlier energy to persist, they don’t try as hard to raise prices. | | This spike doesn’t look so short-lived. Roughly 200 days after the U.S. and Israel attacked Iran, oil is $25 above its preinvasion price. With tanker and refinery capacity curtailed, European inventories depleted and the cushion of higher U.S. exports and lower Chinese imports fading, oil prices look vulnerable to more disruptions, Morgan Stanley warns. | | | | | | | | Second-round effects have so far been narrow, but the bank predicts that, absent a resolution to the war, firms are going to treat higher costs as persistent and raise prices accordingly. It sees core inflation, using the Fed’s preferred measure, at 2.7% in late 2027, above the 2.5% that Fed officials recently projected. | | That means higher interest rates are also likely to persist. Chicago Fed President Austan Goolsbee noted on Monday that central banks aren’t supposed to raise rates in response to supply shocks unless they are persistent. “These days, when you see a large supply shock,” such as Covid-19, tariffs or oil, “it is usually more accurate to assume it will be persistent than to assume it will quickly go away,” he said. |
