Dollar Rises Against Yen as BOJ Dissent Clouds Hikes
The Bank of Japan raised interest rates, but the yen became weaker instead of stronger.
Two policymakers voted against the increase, which made traders less certain that more hikes will follow.
The dollar briefly climbed to 158.05 yen.
Japanese authorities reportedly checked exchange rates, a possible early step before intervening to support the yen.
Japan’s finance minister said Tokyo would not rule out further coordinated action.
The US Federal Reserve had also recently raised rates and suggested more increases could come.
This helped support the dollar against several currencies.
Bitcoin rose nearly 6% to $81,000 as it continued recovering from an earlier drop.
The dollar rose against the yen after the Bank of Japan voted 7-2 to raise rates by 25 basis points.
The Bank of Japan lifted its policy rate to 1.25%, its highest level in 31 years.
Traders questioned whether the dissenting votes and limited hawkish guidance signaled a commitment to additional rate increases.
The dollar reached 158.05 yen before paring gains after a report that Japan conducted foreign-exchange rate checks.
Bitcoin rose 5.9% to $81,000, extending its rebound for a third consecutive day.

Hike Skepticism
Meaning of the BOJ decision
Further-Hike Expectations
The rate increase to 1.25% could support expectations that the Bank of Japan will continue raising rates.
Hike Skepticism
The 7-2 vote and lack of explicitly hawkish guidance led traders to doubt the BOJ’s commitment to additional increases.
Response to yen weakness
Further-Hike Expectations
Japanese authorities’ reported rate checks and warnings of coordinated action could help push back against one-sided yen selling.
Hike Skepticism
The yen’s weakening after a rate increase suggests that official action may be needed because the BOJ decision did not satisfy currency markets.
