Thoughts on JGB Yields and Nikkei Headwinds

Watching the Bank of Japan's rhetoric has become a full-time job. The subtle shifts, or lack thereof, in their stance on yield curve control are giving me whiplash. With JGB yields finally starting to creep up past what most anticipated a few months ago, it's hard not to connect the dots to potential headwinds for the Nikkei. Domestic borrowing costs will inevitably rise, impacting corporate profitability for those heavily reliant on local financing, and could pull some capital out of equities into bonds if the yield becomes attractive enough. We're already seeing some foreign money flow out, which is concerning.

Now, I'm not saying the sky is falling, but a sustained upward trend in JGBs makes me question the easy money narrative that has underpinned a lot of the Nikkei's run. I'm keeping a very close eye on the exporters, as a stronger JPY on the back of rising yields would certainly eat into their margins. I've been trimming some of my more aggressive long positions in growth names there and rotating into more defensive plays, or at least those with significant international revenue streams less tethered to the domestic rate environment. Still holding some core positions, but definitely reducing exposure. What are others thinking about this dynamic? Are we due for a deeper correction if the BOJ truly pivots, or is this just noise around the edges?
