Japanese investors just hit the exit on UK sovereign bonds in a big way. November saw the heaviest selling pressure in 14 years—a serious signal about what's happening in the gilt market right now.

What's driving it? Two things mainly. First, there's growing nervousness about Britain's fiscal trajectory. With concerns mounting over government finances, foreign capital is getting pickier about where it parks cash. Second—and this one's pretty straightforward—yields back home in Japan have ticked higher, making domestic assets more attractive relative to UK gilts.

When you combine fiscal anxiety with better returns elsewhere, it's not hard to see why international investors are rebalancing. The trend matters beyond just the bond market too. Capital flows like these ripple through the broader financial ecosystem, affecting everything from currency dynamics to funding costs across different asset classes.
