• JGB yields declined broadly beyond the 5-year sector this week, supported by (81-3)hiroki.yagi@jpmorgan.com6736-6783

growing market focus on GPIF and a strong 20-year auction. While recent JPMorgan Securities Japan Co., Ltd.

weakness in equity markets could slow pension-related rebalancing into

domestic bonds in the near term, GPIF-related developments are likely to

remain a key market theme. Although we see no need to revise our outlook at

this stage, any large-scale asset allocation shift by GPIF would likely lead us

to reassess our views on JGB supply-demand conditions and long-term interest

rates.

• The National Conference agreed this week to fully introduce income-linked

benefits (refundable tax credits) from FY2029, while a conclusion on

consumption tax cuts was deferred. Although significant hurdles remain,

consumption tax cuts remain the base-case scenario. Discussions on the final

design of the measure, its exit strategy, and its relationship with refundable tax

credits are likely to remain in focus over the coming weeks.

• Finance Minister Katayama’s remarks have heightened market attention

toward a potential review of GPIF’s asset allocation. The market’s sensitivity

to GPIF-related headlines reflects both the perception that GPIF could alleviate

upward pressure on JGB yields and JPY weakness, and a widely held view that

a review of the Basic Portfolio has become increasingly reasonable given the

improvement in domestic bond yields.
