US-Japan move to stop yen slide helps baht appreciate

A joint US-Japan intervention aimed at halting the yen's decline contributed to the Thai baht appreciating beyond 33 baht per dollar, according to economists. Amonthep Chawla, executive vice-president and head of research at CIMB Thai Bank, explained that recent weaker-than-expected US employment data have eased concerns about the Federal Reserve raising interest rates in September.

This has prompted investors to reconsider their expectations, leading some funds that previously moved into US assets to return to emerging markets, thus bolstering currencies like the baht. The baht was traded within a range of 32.99-33.01 to the dollar early yesterday, compared to its Friday close of 33.05, marking its six-week high of 32.87 to the greenback, as reported by Kasikorn Research Centre (K-Research).

Additionally, easing tensions in the Middle East, as well as progress in US-Iran talks, have positively impacted the Thai currency. The Japanese yen has rebounded to 158.52 per dollar, from a multi-decade low of 164 late last month, following the US-Japan intervention. However, Amonthep expressed concerns about the effectiveness of the US-Japan joint intervention, citing potential consequences if Japan resorts to selling US Treasuries to bolster the yen, which could impact the US financial system and economy.

The critical question remains whether Japan can manage the pressure within its domestic financial system or if continued weakness in the yen and rising yields on Japanese government bonds (JGB) could trigger broader volatility in US Treasury markets and the global financial system.
