The last COVID stimulus package added from 1 to 4% to inflation, but that was transitory. The wider rise was largely due to other factors such as supply chain disruptions from the pandemic and Russia's invasion of Ukraine. The latter significantly raised oil prices worldwide which in turn raised costs for all kinds of things.
