Volatile yen draws intervention watch, other currencies subdued

Currency markets kept a close eye on the Japanese yen on Monday, following a significant drop last week that raised concerns about a potential rate check from Tokyo. Investors were closely monitoring the yen's interest rate outlook after a series of hikes by major central banks in the previous week. The yen recovered slightly to 156.64 per US dollar after losing 2% last week.

However, Japan's markets were closed for a three-day holiday, resulting in reduced liquidity and heightened trader alertness for any official intervention to support the volatile currency. The Bank of Japan (BOJ) had increased rates to their highest level in 31 years to 1.25% on Friday, but the expected move failed to strengthen the yen due to two dissenting votes and insufficient hawkish guidance from officials.

This led to a sharp decline in the yen prior to the Nikkei newspaper reporting that Japanese officials had conducted rate checks. A rate check involves authorities asking banks for currency quotes to assess market conditions, often seen as a signal for potential currency intervention. Apart from the BOJ, the Federal Reserve and the European Central Bank also raised rates this month, with both expressing the possibility of further tightening to combat inflation stemming from the ongoing war in the Middle East.

Fred Neumann, HSBC's chief Asia economist, noted that the BOJ's messaging has become increasingly difficult due to the Federal Reserve's hawkish signal, as the Fed unanimously raised its policy rate. The yen had strengthened to its strongest level in seven months in early September, as traders anticipated a more aggressive BOJ rate hike and early signs of Japanese investors repatriating their funds.

However, the yen has since lost some of its gains. Neumann emphasized that the bar remains high for the BOJ to convince markets of its hawkish stance and anchor expectations regarding the yen. He added that investors may once again challenge the BOJ's resolve to raise rates further and align with the Federal Reserve's tightening.

Meanwhile, the euro remained relatively stable at $1.1482 after election results indicated the far-right Alternative for Germany (AfD) emerged as the top party in state elections in northeastern Germany. This outcome has negatively impacted Chancellor Friedrich Merz's conservative party. ING economists highlighted that the fragmented political landscape, fueled by years of economic stagnation, could hinder the country's recovery. They warned that this fragmentation could make the stagnation harder to overcome.

The dollar index, which tracks the US currency against six major peers, remained steady at 100.23 after gaining over 1% the previous week due to the Federal Reserve's rate hike. Traders now estimate a 55% probability of another rate increase at the Fed's October meeting, up from 42.5% a week prior, according to the CME FedWatch tool.

Thomas Simons, chief US economist at Jefferies, stated that the midterm elections are unlikely to hinder the Fed's decision to hike rates again in October. However, the path of future rates will depend on labor market developments and geopolitical events. In the broader economic landscape, the British pound reached $1.339 in early trading, while the Australian dollar was valued at $0.7129, and the New Zealand dollar was trading at $0.5721.
