BOJ Rate Hike Sparks Unexpected Market Rally

The Bank of Japan (BOJ) hiked its benchmark interest rate to 1.25%, its highest level since 1995, but Japanese markets reacted in a surprising way.

The yen weakened past 157 against the dollar, and bond yields on the 10-year Japanese Government Bond slipped. Meanwhile, the Nikkei 225 stock index gained 1.5%.

Experts attribute this unusual market reaction to the BOJ's split decision, with two board members dissenting from the verdict. Toichiro Asada and Ayano Sato argued that the economic situation might not be strong enough to warrant a rate hike, given core inflation is below 2%. The BOJ's policy rate increase was its third in three months.

The decision was also seen as less hawkish than expected, with State Street's Masahiko Loo noting that the BOJ did not update its outlook report. This limited the bank's ability to reinforce a hawkish message through revised forecasts.
