Japan's delicate balance between inflation and economic stability is facing a new challenge as the Iran-Israel conflict escalates. The Bank of Japan (BOJ) has long been on a path towards policy normalization, aiming to end the world's only negative interest rate regime. However, the recent surge in inflation, driven by external factors, poses a significant dilemma for the central bank.
The BOJ's primary concern is the type of inflation Japan is experiencing. "Cost-push" inflation, caused by external factors like rising oil prices, is distinct from the "demand-pull" inflation the BOJ has been striving for. Japan's heavy reliance on oil imports makes this a critical issue. The country is currently facing a situation where rising oil prices, potentially reaching $200 per barrel, could exacerbate inflation, despite the BOJ's efforts to normalize policies.
This is particularly concerning given the ongoing decline in wages. Real wages in Japan fell every month in 2025, with a slight recovery in January. The BOJ's ideal scenario involves inflation fueled by wage growth, creating a virtuous cycle of price and wage increases. However, the current situation suggests a different path.
Thomas Rupf, chief investment officer at VP Bank, predicts a noticeable increase in inflation from March onwards. He attributes this to higher global energy prices, Japan's heavy reliance on imported energy, and a weaker yen. This could lead to a rebound in inflation beyond the BOJ's 2% target, creating a challenging situation for the central bank.
The BOJ's policy bind is evident. If inflation rises, the central bank might need to accelerate normalization to curb cost-driven inflation, which reduces real wages and impacts consumption. This is a delicate balance, as higher rates typically constrain inflation by making borrowing more expensive and slowing economic growth.
Sam Jochim, an economist at EFG, highlights the complex relationship between energy prices and inflation. While energy constitutes a significant portion of Japan's CPI basket, the overall increase in inflation would likely be more substantial due to the input role of energy in production.
Hirofumi Suzuki, chief FX strategist at Sumitomo Mitsui Banking Corporation, agrees that the impact on inflation is limited for now. However, he warns that a 20% increase in oil prices could lead to a 0.3% increase in Japan's CPI. This suggests a potential material strengthening of upward pressure on overall prices.
Despite the challenges, Japan has a silver lining in its significant oil reserves. The country held emergency oil reserves equivalent to 254 days of domestic consumption as of February, according to government data. These reserves provide a degree of mitigation against the price shock.
In conclusion, the Iran-Israel conflict poses a critical test for Japan's economic policies. The BOJ's ability to navigate the delicate balance between inflation and economic stability is crucial. As the conflict continues, the central bank must carefully consider its next moves to ensure Japan's economic health and stability.
