Trader Peter Brandt announced that a short position on the EUR/JPY pair has become the largest futures and currency holding for his firm. The pair, which traded at 175.65 in futures, previously reached a high near 187.5 in April. Since late September, the asset has remained below a support level of 180, according to data from Investing.com.

The market environment is influenced by central bank policies and government interventions. The European Central Bank currently maintains a deposit rate of 2.5%, while the Bank of Japan holds its rate at 1.25%. On July 31, the US Treasury and Japan conducted a joint intervention by selling euros for yen, which strengthened the Japanese currency to 157.57 per dollar from a low of 163.73.

Economic indicators show Japan's core inflation reached 2.1% in September, exceeding the 2% target set by the Bank of Japan. Market expectations, tracked via overnight swaps, suggest an 80% probability of a rate hike by the Bank of Japan in December. Meanwhile, the European Central Bank raised its deposit rate to 2.5% on September 10, though President Christine Lagarde noted no pre-commitment to future rate paths.

Upcoming central bank meetings on October 29 and October 30 will be critical for the EUR/JPY position. While a potential rate hike by the Bank of Japan could support the short trade, actions by the European Central Bank or a decision to hold rates in Japan may impact the strategy. Additionally, officials from the US and Japan have indicated a willingness to intervene in currency markets if necessary.
