Yen weakens against peers after BOJ raises interest rates

The yen weakened sharply against the dollar and other major peer currencies on Friday after the Bank of Japan raised rates to a 30-year high but did not offer clarity on future hikes. The yen fell against the dollar after the BOJ lifted its policy rate to 0.75% from 0.5% in a move that had been well-telegraphed by policymakers, prompting traders to sell.
