Bank of Japan Gov. Haruhiko Kuroda reaffirmed the importance of a concerted policy mix that supports the economy, ahead of a key ruling party election that is almost certain to determine the country’s next prime minister.

Speaking after the BOJ left its policy unchanged and fleshed out more details of its green lending program, Kuroda emphasized the need to keep supporting the economy amid ongoing risks from the pandemic, including supply-side constraints.

Wednesday’s stand-pat decision comes a week before a ruling party election to pick Prime Minister Yoshihide Suga’s successor. The new leader of the Liberal Democratic Party is expected to put together a stimulus package to help the economy get back on a firmer recovery track.
