Asia Overnights Macro Data, Japanese Yen Continues Weakening

The overall tone in Asian markets this morning is shaped by slower Japanese wage growth and weakening corporate sentiment, juxtaposed with supportive current account figures. Yen weakness is driving USD/JPY and affecting yen crosses like AUD/JPY. Australian housing softness and Indonesian consumer caution contribute to a nuanced regional outlook. Investors will monitor upcoming Japanese inflation and BoJ communications for further clues on policy direction. European markets and the US market open will likely take cues from these developments alongside their respective macro releases.

Japan Economic Data

  • Average Cash Earnings YoY rose 1.5% in August, slowing sharply from 3.4% in July and missing consensus forecasts of 2.6%. This slowdown highlights weakening wage growth, a critical factor dampening household spending power. Real wages, already under pressure from persistent inflation above the Bank of Japan’s (BoJ) 2% target, continue to decline, signalling potential softness in domestic demand.
  • Overtime Pay YoY also slowed to 1.3%, down from 3.0% previously, further reflecting moderation in labour compensation beyond base wages.
  • Current Account surplus stood at ¥3,776 billion, well above forecasts and the previous month’s ¥2,684 billion, providing some support for the yen amid global uncertainty.
  • The Reuters Tankan Index declined sharply to 8 in October from 13 in September, and below the expected 15, suggesting weakening business sentiment among Japanese companies.
  • The Eco Watchers Survey, both current conditions (47.1) and outlook (48.5,) modestly beat expectations, indicating some resilience in consumer confidence despite other softness.

Australia Economic Data

  • Building Permits MoM for August declined by 6.0%, an improvement over July’s -10%, but still pointing to a slowing residential construction sector.
  • Private House Approvals MoM fell by 2.6%, signalling ongoing weakness in the housing market.

Indonesia Economic Data

Consumer Confidence in September registered 115.0, below the expected 120, suggesting cautious sentiment among Indonesian consumers.

FX MOVERS

The FX pairs that react fastest to overnight economic data tend to be those involving economies with active trading sessions overnight and high liquidity. According to recent sources, the key pairs with the fastest reactions are:

  • USD/JPY: Highly liquid and active during the Asian session; sensitive to Japanese and US economic data.
  • AUD/JPY and AUD/USD: Reflect economic activity in Australia and Japan, with commodity price influences; often volatile overnight.
  • NZD/JPY and NZD/USD: Influenced by New Zealand economic data and global risk sentiment.
  • EUR/JPY and GBP/JPY: Cross pairs involving major Asian and European economies, reacting to both regions’ economic news.
  • AUD/NZD: Often moves with regional economic reports from Australia and New Zealand and offers stable yet responsive movements overnight.

These pairs show increased volatility and liquidity during the Asian and early European sessions, making them most responsive to overnight economic releases and geopolitical developments.
