Japan's 10-year government bond yield rose 3 basis points to 2.695% in Tokyo morning trade as higher oil prices stoked inflation fears, with markets also watching a ¥600 billion 30-year JGB auction later in the day.

01

Why can oil prices drag down Japanese government bonds?

Higher crude prices push up Japan's import costs, adding to inflation pressure.
This means → markets are betting the Bank of Japan may accelerate rate hikes, weighing on bond prices and lifting yields.
The 10-year JGB yield rose 3 basis points to 2.695%, tracing the "oil → inflation → rate hikes" chain.
02

What does the market expect from the 30-year auction?

Japan's Ministry of Finance is holding a roughly ¥600 billion 30-year JGB auction today.
Citi Research rates strategist Tomohisa Fujiki expects relatively strong results, with demand driven mainly by domestic Japanese investors.
In plain terms = local institutions are the main buyers here; offshore capital is not the key player in this auction.
03

What is behind the improving supply-demand picture?

Fujiki noted that the supply-demand improvement largely stems from a reduction in issuance size.
This means → demand did not suddenly surge; the Ministry of Finance simply put less debt on the table, and tighter supply brought the balance closer to equilibrium.
This reflects a deliberate effort by the Japanese government to pace ultra-long-dated issuance and avoid overwhelming the market.
