This is the latest in my series of podcasts explaining how economics works in the credit crunch and now virus pandemic era. This week I give my thoughts on Does it really matter how big the US national debt gets, or not? What happens if the public finances lose "headroom"? Are EU & UK allowing manipulating their currencies to fall to counter Trump tariffs? What is currently giving confidence to the pound? Are National Insurance rises inflationary or deflationary? How will Chinese dollar denominated bonds sold in Saudi affect the world economy?
