Is a technology investment boom driving long-term bond yields higher?
Core argument: Bruegel notes that US, German, French, Italian, UK, and Japanese 30-year yields all rose by 45–79 basis points in the six months to August 28, with the US in the middle at 58 basis points.
What [has been] driving interest rates higher [in the six months to August 28]? The European think tank Bruegel notes “US, German, French, Italian, UK, and Japanese 30-year yields [all] rose by 45-79 basis points in the six months to 28 August, with the US in the middle at 58bp.” It may not have much to do with policy at all, [but is instead due to] the surge in demand for funds as a result of the AI boom. We are in the midst of a surge in spending on IT that is on track to be even bigger than the boom of the late 1990s, [when] long-term rates were even higher then than they are now, even though inflation was low and we had a budget surplus.
