I've already said with respect to the fiscal and monetary measures that I think, under the circumstances, they were broadly appropriate. When it comes to whether they were exactly right, I would cut people quite a bit of slack, because they were operating on such a scale and under such time pressure.
Having said that, though, we now have a situation where nominal spending is growing far more quickly than the economy's ability to produce goods and services. I would express what you did about supply chain issues a little differently. It's true that some are spectacularly worse than others—particularly in energy markets right now—but across the board, what we're seeing is a constrained ability of the economy to produce goods and services. The labour market has come back very strongly, but business investment has been very weak and productivity growth has been weak.
The ability of the economy to generate goods and services in real terms is constrained. If you continue to run a monetary policy and fiscal policy that presume that the economy can grow a lot more quickly in a sustained way, you'll end up with inflation, because you've got too much money chasing too few goods and services.
