Japan's Nikkei index fell 0.8% to 64,597.46 by the end of the morning session, while the broader Topix index declined 0.3% to 4,032.89. The drop comes amid rising oil prices and heightened expectations of a Bank of Japan rate hike next week, following geopolitical tensions and potential inflationary pressures.
The escalation in the Strait of Hormuz, where Iran attacked 10 ships after the US sank five Iranian oil tankers, has pushed crude oil prices above $100. This geopolitical tension has driven global bond yields higher as investors anticipate tighter monetary policies from central banks.
In Japan, expectations of a rate hike by the Bank of Japan have increased after board member Kazuyuki Masu warned of the risk of falling behind on inflation. This has added pressure on Japanese equities, with strategists at Nomura Securities citing higher crude oil prices and interest rates as key factors.
Despite the current market pressure, there is optimism for solid earnings growth among Japanese companies, particularly in the artificial intelligence and semiconductor sectors. Investors may find opportunities to buy on dips, although the market could face limited upside without new catalysts.
Nintendo was among the biggest decliners on the Nikkei, dropping 5.8%, while data-centre cable makers Fujikura and Furukawa Electric fell 5.7% and 4.8%, respectively. Conversely, energy-related stocks gained 1.1%, and securities firms and banks rose 2.1% and 1.9%, respectively, benefiting from higher interest rates.
Background
The ongoing geopolitical tensions and rising oil prices have significant implications for global markets, as they could lead to tighter monetary policies and increased inflationary pressures. The Bank of Japan's potential rate hike is part of a broader trend of central banks responding to these economic challenges.
As markets brace for key events, including US consumer price data and the Federal Reserve's policy decision, investors will closely watch the Bank of Japan's upcoming monetary policy decision for further direction.
