• Eurozone inflation slows more than expected in June, lowering expectations of further ECB rate hikes.
• Joachim Nagel's cautious comments fail to provide meaningful support to the single currency.
• The Japanese Yen benefits from safe-haven demand and fears of intervention by Japanese authorities.

EUR/JPY trades around 185.40 at the time of writing, down 0.15% on Wednesday, as the Euro (EUR) weakens while the Japanese Yen (JPY) gains strength. The single currency is pressured by a sharper-than-expected slowdown in Eurozone inflation, while the Japanese currency is supported by both its safe-haven appeal and speculation over possible intervention by Japanese authorities.

Preliminary data showed that the Eurozone Harmonized Index of Consumer Prices (HICP) increased by 2.8% YoY in June, down from 3.2% previously and below market expectations of 3%. On a monthly basis, the index declined by 0.1% after rising by 0.1% in May.

Core HICP, which excludes volatile items such as food and energy, also eased more than expected, rising by 2.4% YoY in June, down from 2.6% previously and below the 2.6% consensus forecast. On a monthly basis, Core HICP increased by 0.2%, slowing from the previous 0.3% rise.

The softer-than-expected inflation readings lower expectations of further European Central Bank (ECB) rate hikes, weighing on the Euro. Before the inflation data release, comments from ECB Governing Council member and Deutsche Bundesbank President Joachim Nagel provided only limited support for the European currency. Nagel said that inflation risks remain tilted to the upside and that he is keeping all options open for the July and September policy meetings. He also stated that inflation will remain elevated this year and stay above the ECB's target in 2027, while stressing that the June rate increase was not an insurance hike.

Meanwhile, the Japanese Yen (JPY) continues to strengthen. Market participants remain alert to the risk of intervention after Japan's Finance Minister Satsuki Katayama said on Tuesday that authorities are ready to respond to excessive currency moves whenever necessary, although she declined to comment on any specific exchange rate level.

The Japanese Yen is also supported by comments from newly appointed Bank of Japan (BoJ) board member Ayano Sato, who said that companies are becoming more active in raising wages and prices, suggesting that the impact of a weaker JPY on inflation could now be greater than in the past. She also stated that monetary policy should remain focused on inflation, while fiscal policy should address the impact on households and businesses.

Analysts at Societe Generale also believe that investors are once again testing the resolve of Japanese authorities. The bank noted that 165 on USD/JPY could represent a new line in the sand following previous interventions and warned that a significant short-covering rally in the Japanese Yen could emerge if markets reassess the outlook for the Federal Reserve (Fed) or if the Bank of Japan continues raising interest rates.
