The top thing on the hosts' mind is the spike in interest rates, and the cause is "very obvious" from a single Wall Street Journal chart: the war. U.S. attacks on Iran in early 2026 sent rates climbing, and they have not come back down. The 10-year yield is now above 5% for the first time since 2007, and mortgage rates are above 7%. This is bad for everyone: the U.S. government must refinance debt at higher cost, homebuyers face unaffordable mortgages, and even AI companies need to raise more capital to finance data center build-outs. The core mechanism is that war causes energy shortages, which drive inflation, which hurts the value of treasury bonds and pushes yields up.
