TOKYO, July 8 (Reuters) - Japan's government is considering revising language on monetary policy in its economic blueprint, a draft obtained by Reuters showed, as market fears it is infringing on central bank independence push bond yields to multi-decade highs.
The possible change highlights the balancing act facing Prime Minister Sanae Takaichi, whose dovish stance and preference for aggressive fiscal and monetary support have unsettled investors and intensified
scrutiny of her administration's influence over policy as borrowing costs climb.
Since taking office in October, Takaichi has vowed to boost investment and focus on spending to revitalise the economy. Her administration has also signalled reservations over the Bank of Japan's interest rate hikes.
In a draft economic blueprint released last month, the government said it was "very important for monetary policy to be guided appropriately to achieve a stronger economy."
Some analysts said the wording sparked a selloff in Japanese government bonds, fuelling concerns that the government could pressure the BOJ to keep interest rates low and risk falling behind the curve as inflationary pressures build.
In response, the government revised the language to emphasise the importance of the BOJ conducting appropriate monetary policy "to achieve stable inflation" as Japan seeks to strengthen its economy, according to the revised version of the blueprint obtained by Reuters on Tuesday.
Several domestic media outlets, including the Nikkei business daily, had earlier reported that the language could be revised.
The revised blueprint draft, however, retained a key passage urging the central bank to align its policy decisions with the government's economic agenda.
The new draft was submitted to a meeting of ruling coalition lawmakers on Tuesday. A final version of the blueprint, which will be the first since Takaichi took office, will be released after cabinet approval later this month.
Japan's law grants the central bank independence from political interference, but it also requires close coordination with the government's economic policy.
Citing that coordination mandate, the Takaichi administration and its reflationist advisers have urged the BOJ to proceed cautiously with further rate hikes.
However, inflation has hovered around the central bank's 2% target for four years, underpinned by rising import costs from the yen's persistent weakness and steady wage growth, reinforcing the BOJ's argument for lifting still-low borrowing costs.
The BOJ raised interest rates twice since Takaichi took office, including in June when it took its key policy rate to a 31-year high of 1%, and has made clear it stands ready to tighten further to prevent inflation from getting out of hand.
Underscoring the bank's vigilance on price pressures, even dovish board member Toichiro Asada said "relatively rapid" pass-through of higher costs warranted close attention.
