The Japanese yen has started the week with sharp losses. In the European session, USD/JPY has jumped 1.2% on the day and is trading at 147.82. The yen has fallen to five-week lows against the US dollar.
Yen sinks as oil prices rise
The fallout from the US attack on Iranian nuclear facilities over the weekend is being felt in the currency markets. The Japanese yen, traditionally a safe-haven currency, continues to depreciate, in response to rising oil prices.
Oil prices rose to their highest level since January on Monday after the US attack on Iranian nuclear facilities. Iran has threatened to close the Straits of Hormuz, a critical trade route through which 20% of the world's oil supply passes through each day. Oil prices have jumped about 10% since the Israel-Iran war started on June 13 and fears of a disruption to oil supply could further boost oil prices.
As oil prices have climbed, the yen has lost ground, declining 3.0% since the Israel-Iran war started. Japan imports almost all of its oil and the rise in oil prices is hurting Japan's trade balance.
Japan Core CPI rises to 3.7%
Japan's core inflation rate climbed 3.7% y/y in May, up from 3.5% in April. Core CPI has accelerated for a third straight month and hit its highest level since Jan. 2023. This was above the market estimate of 3.6%. Headline inflation ticked lower to 3.5% from 3.6% in April, below the forecast of 3.6%.
The rise in core CPI supports the case for the Bank of Japan to boost interest rates, but the uncertainty over tariffs and the Israel-Iran war will likely mean that the BoJ will stay on the sidelines in the coming months.
