EUR/JPY rose as the Yen weakened due to easing Japanese Government Bond (JGB) yields following a solid 10-year auction. This move ended EUR/JPY’s three-day losing streak, trading around 186.29. Japan’s 10-year yield recently hit 1.88%, a high not seen since 2006, bolstered by hawkish comments from BoJ Governor Kazuo Ueda.

Rising JGB yields increase Japan’s debt-servicing costs, potentially limiting the BoJ’s ability to tighten policy. However, Tuesday’s auction eased yield pressures with a bid-to-cover ratio of 3.59, surpassing November’s 2.97 and the 12-month average of 3.20. The BoJ’s upcoming policy decision, expected on December 18-19, indicates an 80% chance of a rate increase to 0.50%.

Japanese Finance Minister Shunichi Katayama expects the BoJ to pursue appropriate monetary policy to achieve its price target, indicating alignment between the government and BoJ. In the Eurozone, stable inflation data supports the expectation that the ECB will maintain its current policy, with the Harmonized Index of Consumer Prices increasing by 2.2% in November year-on-year, slightly above forecasts. The Eurozone unemployment rate was 6.4% in October, consistent with September.

Current Market Outlook

Based on the current situation, we see the Japanese Yen weakening today because a successful government bond auction has temporarily pushed down yields. This short-term move goes against the bigger picture, where the Bank of Japan (BoJ) is expected to raise interest rates soon. This clash between short-term market noise and long-term policy expectations creates a clear opportunity for traders.

The main event to watch is the Bank of Japan’s meeting on December 18-19, where markets are pricing in a very high chance of an interest rate hike. Recent data supports this view, as Tokyo’s Core CPI for November 2025 remained at 2.5%, staying stubbornly above the BoJ’s 2% target for over a year and a half. A rate hike should fundamentally strengthen the Yen, pushing the EUR/JPY pair lower.

Given this outlook, one strategy is to consider buying put options on EUR/JPY with expiration dates after the BoJ meeting. This allows for a bet on the pair falling while capping the maximum loss at the price paid for the option. Be aware that implied volatility is likely elevated, making these options more expensive as the meeting approaches.

Market Risks and Considerations

However, we must remember the market’s reaction to the BoJ’s historic rate hike back in March 2024, when the Yen actually weakened as the news was already priced in. There is a risk that even if the BoJ hikes as expected, a “sell the fact” reaction could occur if their forward guidance isn’t aggressive enough. This suggests the initial move might be counterintuitive.

There is also a significant risk if the BoJ fails to deliver the expected rate hike. The most recent Commitment of Traders report shows that speculative positioning remains heavily short the Yen. A dovish surprise from the BoJ would likely trigger a massive short squeeze, sending EUR/JPY sharply higher.

On the other side of the pair, the Euro is offering little drama, which helps isolate the Yen as the primary driver. Data from Eurozone interest rate markets shows traders are pricing in no policy changes from the European Central Bank for the next several months. This stability in the Euro makes the EUR/JPY pair a cleaner way to trade expectations for the BoJ’s upcoming decision.
