Asian equities advanced Friday as investors responded to a combination of lower oil prices, steadier U.S. Treasury yields and stronger technology shares on Wall Street. The improvement in risk appetite came despite an increasingly restrictive global monetary-policy environment, with major central banks attempting to contain inflation while energy markets remain affected by the prolonged conflict in the Middle East.

MSCI’s broadest index of Asia-Pacific shares outside Japan gained approximately 1%. Japan’s Nikkei rose 0.8%, while South Korea’s technology-heavy KOSPI climbed more than 2%. The moves indicate that declining energy prices provided some relief to investors concerned about the inflationary consequences of crude oil remaining above $100 a barrel.

BOJ Raises Rates, but Yen Weakens

The Bank of Japan increased its policy rate from 1% to 1.25% in a 7-2 vote, taking borrowing costs to a 31-year high. The central bank said the move was intended to limit the risk that inflation would move beyond its 2% target.

Despite the expected increase, the yen weakened 0.5% to 156.75 per U.S. dollar immediately following the decision. The currency remains nearly 2% stronger for the month, reflecting earlier expectations that the BOJ could accelerate its tightening cycle.

The two dissenting votes have also left markets assessing how aggressively Japanese policymakers may proceed. Investors are likely to focus on Governor Ueda’s guidance for indications about whether another increase could arrive as early as December.

Global Central Banks Remain Focused on Inflation

Japan’s move comes amid a broader shift toward tighter monetary policy. The Federal Reserve raised rates this week for the first time in three years and indicated that additional increases could follow. The Bank of England has warned that prolonged Middle East tensions could create circumstances requiring another rate increase, while the European Central Bank has also signaled continued concern over inflation.

Australia is facing similar pressures. Reserve Bank of Australia Governor Michele Bullock said some of the upside inflation risks previously identified by policymakers appeared to be materializing, raising questions about whether three rate increases this year would be sufficient to return inflation to the 2%-3% target range.

Oil Retreat Provides a Temporary Buffer

Brent crude futures fell as much as 1.5% to $103.29 per barrel amid expectations that alternative routes could help maintain oil supplies from the Middle East. However, concerns surrounding strikes involving Saudi Arabia and Yemen’s Houthis remain an important source of uncertainty for energy markets.

Lower crude prices helped support sentiment after a sharp bond-market selloff earlier in the week pushed the U.S. 10-year Treasury yield above 5%, its highest level since 2007. The yield subsequently eased to around 4.936%.

Currency and Gold Markets Reflect Ongoing Uncertainty

The euro held around $1.148 but remained on track for a weekly decline of approximately 1%, while spot gold gained 0.5% to $4,361 an ounce. These moves highlight the competing forces affecting global markets as investors balance inflation risks, interest-rate expectations, geopolitical uncertainty and changing demand for defensive assets.

What Could Investors Watch Next?

The direction of oil prices could remain critical for Asian and global markets. A sustained decline in crude could ease some inflation pressure and provide central banks with greater flexibility, while another energy-price surge could reinforce expectations for additional rate increases.

Investors will also monitor the BOJ’s communication, U.S. Treasury yields and signals from other central banks. The interaction between energy prices and monetary policy is likely to remain a defining factor for equity, currency and bond markets as geopolitical risks persist.
