Yen Pressured by Policy Divergence as Asian Currencies Trade Mixed

Asian currencies showed a mixed performance in Tuesday trading as the U.S. dollar consolidated its recent gains, while the Japanese yen remained under pressure from the wide interest rate differential between Japan and the United States.

Trading was relatively thin with Japanese markets closed for a holiday, but the yen continued to be a key focus for investors following the Bank of Japan's recent policy decisions.

Yen Weakness Lingers on Policy Gap

The Japanese yen's weakness reflects the ongoing policy divergence between a hawkish U.S. Federal Reserve and a more cautious Bank of Japan. The yen's pair against the dollar (USD/JPY) edged up 0.1%, keeping the currency near recent lows.

According to DBS FX & Credit Strategist Chang Wei Liang, markets were disappointed by the BOJ's reluctance to signal a faster pace of monetary tightening, even after its 25-basis-point rate hike in September. The decision was not unanimous, with two board members dissenting, further highlighting the central bank's cautious approach.

Markets remain on alert for potential currency intervention from Japanese authorities. A recent "rate check" is often seen as a precursor to such moves. Chang noted that Japan holds around $1 trillion in foreign-exchange reserves, providing significant capacity to support the yen if needed.

Dollar Steadies, Oil Prices in Focus

The U.S. dollar index, which measures the greenback against a basket of currencies, was little changed around 100.36 after surging more than 1% last week following the Federal Reserve's hawkish rate hike. The steadiness of the dollar provided a mixed backdrop for other regional currencies.

Elevated oil prices, with Brent crude hovering around $100 a barrel, are a significant factor for energy-importing nations. The Indian rupee (USD/INR) was little changed at 95.80, while the Indonesian rupiah weakened, with the USD/IDR pair rising 0.3%.

Divergence Across the Region

Elsewhere in Asia, currency movements were varied:

• The South Korean won (KRW) strengthened sharply, with its pair against the dollar falling 1.17%.
• The Chinese yuan (CNH) remained firm near a 3.5-year high against the dollar, trading around 6.6953.
• The Australian dollar (AUD) traded near $0.7123 as markets awaited comments from Reserve Bank of Australia Governor Michele Bullock, with traders pricing in a high probability of another rate hike.
• The New Zealand dollar (NZD) rose to $0.5735 after Reserve Bank of New Zealand Governor Anna Breman warned that a sustained rise in oil prices would likely lead to higher-than-forecast inflation.
