There are not that many people still working in investment who can remember a time when Japanese government bond (JGB) yields did not trend inexorably down. They peaked in 1990, just after the bubble began bursting, and declined through most of the following 35 years.
For the entirety of my career, shorting JGBs has been known as the “widow-maker”. No matter how low yields went, they always found a way to fall further, wiping out anybody reckless enough to bet that the bottom had been reached.
This may be why the big upward moves in longer-dated JGBs over the past year have not drawn as much attention as you would expect. Anyone who has been conditioned to expect JGB yields to be low forever will instinctively doubt that it can last. This is a brief upheaval, and they will soon head right down again.

Yet, something fundamental seems to have shifted. The 30-year JGB currently yields 2.9%, comparable to the 30-year bund at 3.1%. It had ticked up to almost 3.2% before the Bank of Japan said it would reduce the pace at which it is stepping back from quantitative easing (QE), while the Ministry of Finance indicated it would issue less ultra-long-dated debt in future.
The implications of this are significant – not just for Japan but also for global markets, because low-yielding Japanese debt has been a key funding source for many global carry trades. Borrow at low rates in one currency, invest in higher-yielding assets in another, pick up the difference in returns and hope you can unwind the trade before something – eg, typically a massive currency move – leaves you with sudden losses.

Long-dated JGBs signal uncertainty everywhere
Still, the higher yields on long-dated JGBs don’t imply that Japanese monetary policy is going to normalise any time soon. Markets are pricing in a very drawn-out adjustment – while the 30-year JGB and the 30-year bund are now in line, five-year yields are still well over a percentage point apart (0.97% vs 2.18%). This long-term distortion in global markets may gradually unwind – which is likely to be bullish for the yen over the long term – but it’s not immediate, or so the market thinks. Whether this may be too sanguine is another matter: if inflation (3.5% in May) remains high, rates should go up faster.
Instead, what long-dated bonds are signalling in Japan and elsewhere is a huge amount of uncertainty. Take the US 30-year Treasury, which now yields 4.8%. This doesn’t seem to be due to fears of runaway inflation in particular, because the 30-year inflation-linked Treasury is yielding about 2.5% (ie, the rate of inflation needed for them to return the same is just 2.3%). Rather, it simply feels increasingly reckless to lock up capital for so long. Investors worry about increased government spending, the potential for large amounts of bond issuance to fund it, politics (at the time of writing, the UK 30-year gilt had ticked up to 5.4%) and much more. They are right to be worried, and current yields still feel like very meagre compensation for those risks.
