Widowmaker trade's lesson: Correct call on Japan yields fails without timing

For nearly 20 years, market participants received a harsh lesson: being correct about an outcome and actually profiting are often two different things.

That harsh lesson frequently originated from the Japanese bond market and the so-called "widowmaker" trade. At the time, this is what observers saw when they examined Japan.

Japan had enormous government debt, ultra-low interest rates, and bond yields that seemed unrealistically low. Many investors experienced a eureka moment, reasoning that eventually the situation would normalise and yields would have to climb.

The strategy was simply to short Japanese government bonds and wait for reality to catch up. But reality never arrived.

Taking on the Bank of Japan was like hitting a brick wall.

The BOJ proved to be an impenetrable wall. For decades, Japan fought deflation through unconventional monetary policies, and the central bank purchased massive quantities of JGBs while implementing yield curve control (YCC) to keep borrowing costs low.

In effect, anyone betting on rising yields by shorting Japanese bonds was pitted against the BOJ. These traders might have been correct that such low yields were economically illogical, but that fact proved irrelevant.

As yields remained low for nearly ten years, those short positions suffered heavy losses due to financing costs, drawdowns and risk constraints. That's how the "widowmaker" nickname emerged.

Then the Covid pandemic arrived.

The pandemic reshaped the landscape.

The black swan event gave Japan a reprieve, helping policymakers reach a goal they had pursued for nearly two decades: a more persistent inflation environment.

It seemed nearly ideal, but the rising inflation came with a drawback as it starts to lead to tighter monetary policy.

Japan is now discovering that exiting deflation means it cannot forever depend on ultra-low rates, which had made its massive debt easy to manage.

This is where the "widowmaker" narrative becomes compelling once more.

As the BOJ has slowly retreated from unconventional policies and inflation heats up again, the bond market is beginning to assert itself.

Japanese 10-year yields surpassed 3% this week, a level not seen since September 1996. This is generating a vicious cycle: higher yields raise borrowing costs, making Japan's fiscal deficit more costly to finance, and growing sustainability worries only push investors to demand even higher yields.

The inflation that Japan laboured for decades to create has now become a source of difficulty.

Being correct about the direction is insufficient.

This may be the key takeaway from the "widowmaker" trade.

Traders who shorted Japanese bonds through much of the 2000s were not necessarily incorrect about the ultimate outcome; they were simply wrong about the timing.

They might have rightly argued that near-zero yields were unsustainable, yet they still lost money for years while waiting for the market to come around.

Ultimately, being right alone does not pay. Markets care as much about timing as they do about reasoning.

In trading, being too early or too late is frequently indistinguishable from being wrong. The "widowmaker" trade serves as evidence.
