Financing the JPY5trn food consumption tax suspension with proceeds from the FX special account would likely open up gaps in the general budget
This leaves the Japanese finance ministry with three options: Plug the gap through increasing the efficiency of the tax base and expenditure, net liquidation of parts of the FX special account, or higher JGB issuance through the backdoor
Which one of these options it chooses may have substantial consequences for JPY as well as JGB yields. Special account partial liquidation would be a notable JPY positive
