The euro extended gains against the yen for a fourth straight session on Wednesday, trading above 185.46 for the first time since an alleged intervention on 30 April. The yen weakened versus major peers after Bank of Japan Governor Kazuo Ueda warned about second-round inflation effects and argued central banks should not assess oil prices in isolation, as a temporary energy shock can become persistent if it reshapes wages, expectations and price-setting behaviour. Markets continued to price in potential BoJ tightening at the 15 June meeting, but the currency response was limited.
Pressure on the yen persisted as concern over Japan’s exposure to higher crude prices and the relatively low yield on Japanese Government Bonds reduced demand. In the eurozone, comments from European Central Bank officials underpinned expectations for tighter policy. ECB board member Isabel Schnabel said on Tuesday that ignoring the inflation spike was no longer viable and that a June rate rise would be needed, while chief economist Philip Lane appeared relaxed about market pricing for an imminent hike during an interview with Nikkei.
Volatility and Central Bank Dynamics
Given the EUR/JPY is pushing above 185.50, we see this as a critical zone fraught with intervention risk. One-month implied volatility for the pair has consequently jumped to 12.5%, reflecting deep market uncertainty ahead of the June central bank meetings. This setup suggests that simply staying long is now a high-risk proposition.
The Bank of Japan’s hawkish talk is being ignored because the interest rate differential remains a powerful force. With the latest Tokyo Core CPI for May hitting 2.8%, well above target, the market is pricing in a policy tweak on June 15. However, with German 10-year bunds yielding 3.25% against the 10-year JGB’s 1.10%, the 215 basis-point gap makes funding trades in yen too attractive to pass up.
On the other side of the trade, the Euro is showing its own fundamental strength. Flash inflation data for the Eurozone just showed the headline rate remaining sticky at 2.7%, reinforcing the ECB’s need to act. We therefore fully expect a 25 basis point rate hike from the ECB in June, which is providing a solid floor for the Euro.
Strategic Approaches and Risk Management
For the coming weeks, we believe buying volatility is the most prudent strategy. We are looking at purchasing EUR/JPY straddles or strangles with an expiration in late June to capture a potentially explosive move in either direction following the central bank meetings. This strategy profits from a large price swing, whether it’s a continued rally or a sharp drop from a surprise intervention.
For those already holding long positions, we advise hedging against a sudden downturn. Looking back at the interventions of 2024, moves of 5-7 yen can happen in hours. Buying out-of-the-money JPY call options is a relatively cheap way to protect profits from a sudden and sharp reversal initiated by Japanese authorities.
