Finance Minister Masajuro Shiokawa said Monday he does not think the Bank of Japan is considering purchasing foreign bonds as a means of boosting liquidity in the money market.
"I have not been asked to give advice on that and I have not heard any information," Shiokawa told a news conference.
Last week, the Financial Times reported the BOJ Policy Board had raised the possibility of buying foreign bonds as a way to further ease monetary policy and push the yen lower.
Shiokawa said he does not think the BOJ is formally discussing the idea, although some economists and critics are saying the measure may be taken to boost liquidity.
He said the government wants the central bank to take measures to bolster liquidity but that the specific steps are "up to the bank."
