JGB yields rise 2bps as tankan data fuels BOJ rate path debate

Japan's bond market sold off Tuesday as a blockbuster BOJ tankan survey reinforced the case for further rate increases, even as the central bank navigates the aftermath of the Iran conflict's energy shock.

Japanese government bonds fell during the morning Tokyo session, tracking overnight price declines in U.S. Treasurys, with the 20-year yield rising 2 basis points to 3.675% and the 30-year yield climbing 2 basis points to 3.965%. Both JGBs and Treasurys tend to move in tandem, and the selloff was compounded by ongoing yen weakness, which typically lifts import prices and inflation and could prompt the Bank of Japan to raise rates at a faster pace.

"The negative impact from rising raw material costs from the Iran war was offset somewhat by brisk demand for AI-related goods and chips," a Bank of Japan official told a briefing following the release of the tankan survey.

The Bank of Japan's quarterly tankan survey, released Wednesday, showed the index measuring sentiment among large manufacturers at +22, up from +17 in March and above the +16 consensus forecast from economists polled by Quick. That marks the highest reading since March 2018. The large non-manufacturers sentiment index rose to +37 from +36, also beating the +35 consensus and reaching its highest level since August 1991.

Large Japanese firms now plan to increase capital expenditure by 11.5% in the current fiscal year ending March 2027, a sharp acceleration from the 3.3% rise planned in the previous survey and above the 10.5% median market forecast. The survey likely does not fully reflect the recent progress toward a U.S.-Iran peace deal on June 15, the BOJ official noted, as most firms responded before the agreement.

Rate Path and Inflation Dynamics

The tankan results will be among the factors the BOJ scrutinizes at its next policy meeting on July 30-31. The central bank raised interest rates to a 31-year high in June, a landmark step in its policy normalization, and has signaled readiness to tighten further as it focuses on taming price pressures from the Iran-war-induced energy shock.

Wholesale inflation in Japan spiked to a three-year high of 6.3% in May, a sign that companies were already passing on higher costs from the energy shock. While the U.S.-Iran peace deal has eased some market fears over global price pressures, the BOJ's policy path remains complicated by the need to balance inflation control against an economy dependent on imported fuel.

The yen's persistent weakness adds another layer of complexity. A weaker yen inflates import costs, feeding into consumer prices and potentially accelerating the timeline for BOJ action. The central bank's board will release fresh quarterly growth and inflation forecasts at the July meeting, which will serve as a guide to the pace and timing of future rate increases.

The last time the tankan large manufacturers index reached similar levels in early 2018, the BOJ maintained its ultra-loose policy stance for another six years before beginning the current normalization cycle. This time, with inflation running well above the 2% target and the yen under sustained pressure, the central bank faces a fundamentally different calculus.
