The Japanese yen traded flat against the US dollar on Tuesday, with USD/JPY around 145 as investors awaited the Jackson Hole Symposium later this week. Federal Reserve Chair Jerome Powell is expected to offer clues on the timing and scale of potential US interest-rate cuts. The dollar index remained stable and US Treasury yields held firm, encouraging cautious trading ahead of the event. The yen has faced pressure for much of the year because of the wide interest-rate differential between Japan and the United States, while the Bank of Japan’s gradual monetary-policy normalization has provided limited support. Japanese officials have warned that they are monitoring currency movements and could respond to excessive volatility, with the 145 level viewed by market participants as an important threshold. Traders will also assess US jobless claims and durable goods orders. Stronger data could support the dollar, while weaker figures could revive rate-cut expectations and ease pressure on the yen. A dovish signal from Powell could weaken the dollar, whereas a hawkish surprise could lift USD/JPY and increase intervention risks. The symposium may set the tone for currency markets in the coming weeks, leaving investors prepared for possible volatility.
