Japanese Yen extends its fall as US-Japan rate gap underpins US Dollar

• USD/JPY extends its advance and trades near its highest level in several decades.
• The US-Japan interest rate differential continues to support carry trades.
• Expectations of further Federal Reserve rate hikes are also underpinning the US Dollar.

USD/JPY trades around 162.65 at the time of writing, up 0.44% on the day, and remains close to its highest level in several decades. The pair continues to benefit from a supportive backdrop for the US Dollar (USD), while repeated warnings from Japanese authorities about possible foreign exchange intervention have failed to reverse the broader trend.

The Japanese Yen (JPY) remains weighed down by the wide interest rate differential between Japan and the world's major economies. The Bank of Japan (BoJ) raised its policy rate to 1% in June, its highest level since 1995, but it remains well below the Federal Reserve's (Fed) 3.5% to 3.75% target range. This gap of around 250 basis points continues to support carry trades at the expense of the Japanese currency.

Meanwhile, the US Dollar is regaining strength after its recent pullback. Ongoing tensions surrounding Iran continue to fuel inflation concerns and reinforce expectations of additional monetary tightening by the Fed. According to the CME FedWatch tool, markets are now assigning a high chance to another rate hike before the end of the year. These expectations were also reinforced by comments from Cleveland Fed President Beth Hammack, who said inflation remains too high and that the Fed may need to consider further rate hikes if price pressures persist.

Recent US economic data also support this outlook. The Job Openings and Labor Turnover Survey (JOLTS) showed job openings rose to 7.594M in May, above market expectations, while investors now await Wednesday's ADP Employment Change report and Thursday's Nonfarm Payrolls (NFP) report for further clues on the Federal Reserve's policy path.

On the Japanese side, policymakers continue to issue verbal intervention warnings. Chief Cabinet Secretary Minoru Kihara reiterated that authorities stand ready to take the necessary action in the foreign exchange market if needed. Finance Minister Satsuki Katayama also said the government would respond appropriately to excessive currency moves. According to ING, the risk of another intervention remains elevated after USD/JPY broke above 162, although the persistent strength of the US Dollar could limit the effectiveness of any action by Japanese authorities.

Meanwhile, discussions within the Bank of Japan continue to support expectations for a gradual normalization of monetary policy, with several policymakers recently highlighting the risks of more persistent inflation. However, despite the central bank's more hawkish stance, Japan's still-low interest rates continue to limit the Japanese Yen's appeal against a US Dollar supported by expectations of a still-restrictive monetary policy.
