Nikkei Slips on Iran Oil Fears as BOJ Holds Rates, Signals 2027 Hikes

What happened

The Japanese stock market, represented by the Nikkei Stock Average, fell by approximately 0.5% to around 62,400 points. This decline was primarily driven by semiconductor and electronics shares, such as Advantest (down 1.7%) and Murata Manufacturing (down 1.0%). The dollar, meanwhile, remained stable around 157 yen. Investor concern centers on developments in the Middle East conflict and rising oil prices, which hit a five-month high last Friday. For an economy like Japan's, heavily dependent on energy imports, higher oil prices represent a significant risk. Regarding monetary policy, the Bank of Japan (BOJ) is expected to keep its policy rate unchanged at 1.25% at this week's meeting, assessing the effects of its previous rate hike. However, ING economists project two further 25 basis point hikes in January and April 2027, which would raise the policy rate to 1.75%.

Why it matters

Japan's reliance on energy imports makes it vulnerable to any escalation in oil prices, especially in the context of the Iran conflict. A sustained increase in crude costs could pressure corporate margins, worsen the trade balance, and keep the yen soft. Furthermore, imported inflation would be reinforced, complicating the BOJ's preference to wait and potentially pulling hike expectations forward. The expectation that the BOJ will hold rates this week is already priced in, shifting investor focus to the central bank's communication and upcoming economic data. A more hawkish tone from the BOJ could offer some relief to the yen.

Market impact

• Interest rates and bonds: With the BOJ's rate hold already priced in, JGB (Japanese Government Bond) yields are likely to react more to the central bank's forward guidance than to the decision itself. A more hawkish tone, signaling the possibility of earlier rate hikes projected for 2027, could lead to an increase in longer-term bond yields.
• Dollar and FX: The yen is likely to remain under depreciation pressure, especially if oil prices continue to rise and geopolitical risks persist, impacting Japan's trade balance. A more hawkish BOJ, however, could offer temporary relief to the currency, strengthening it against the dollar.
• Equities: Japanese stocks, particularly the technology and semiconductor sectors, are the most sensitive to risk-off swings driven by Middle East headlines and higher energy costs. Pressure on margins for energy-importing companies tends to negatively impact earnings and, consequently, stock prices.
• Commodities: Oil prices are likely to remain a dominant factor, with any escalation in the Iran conflict or supply disruptions potentially driving further increases, given the market's sensitivity to these events.

What to watch

Investors should closely monitor developments in the Middle East and the evolution of crude oil prices, which are the primary near-term risk drivers. Regarding Japanese monetary policy, attention will be on the tone of the BOJ's communication after this week's meeting, looking for signals about the potential acceleration of future rate hikes. Additionally, the release of economic data such as Tokyo inflation figures for October (headline and core CPI), September retail sales, and industrial production will be crucial for assessing the health of the Japanese economy and influencing monetary policy expectations.

Scenarios

Base case: The BOJ maintains the rate at 1.25% and signals caution, with future rate hikes occurring as projected for 2027. The yen remains under pressure but without major depreciation, while the Nikkei remains volatile, sensitive to Middle East news. Risk scenario: A significant escalation in the Iran conflict leads to a sharp and sustained increase in oil prices, forcing the BOJ to adopt a more hawkish tone and accelerate rate hikes, which could strengthen the yen but further pressure Japanese equities.
