Some market players bet the central bank could widen the allowance band set around its yield target to arrest market distortions caused by its heavy bond buying.
With the 10-year yield moving stably below the 0.5% yield cap, however, many BOJ policymakers see no imminent need to take fresh steps against the side-effects of YCC, the sources said.
Notwithstanding abrupt moves in the bonds and yen, the BOJ is likely to make no changes to its policy framework next week, they said.
"We expect the BOJ will keep major policy levers unchanged next week," said Stefan Angrick, senior economist at Moody's Analytics.
More than three-quarters of economists polled by Reuters said they expect the BOJ to keep policy steady including its yield control scheme next week.
