The new key fiscal target will probably become halving the ratio of the primary balance deficit to gross domestic product by the end of fiscal 2013, according to a draft of the government's upcoming fiscal guideline.

The draft, a copy of which was obtained Thursday by Kyodo News, states that the government will then aim to realize the surplus ratio by around the end of 2019.

Concerning the ratio of outstanding public debt to GDP, the draft says the government will try to stop the ratio from expanding by around 2015 and reduce it in a stable manner thereafter.
