The Fed will look through that and expect it to be temporary. It's when it gets into the core... when it starts to get into some of the consumer products out there, that would be a concern. If energy prices stay elevated long enough to bleed into core inflation via transport, manufacturing, and agricultural costs, the Federal Reserve will be forced to abandon any planned rate cuts. Combined with the fact that housing inflation is currently underreported due to a government shutdown, true core inflation is likely stickier than the Fed expects. This higher-for-longer rate environment will drive long-end yields higher, crushing the value of long-duration bonds. SHORT long-duration Treasuries as sticky core inflation and energy shocks will prevent the Federal Reserve from cutting interest rates. The war causes a severe global recession and a massive flight to safety, prompting investors to buy US Treasuries regardless of inflation, driving yields down.
