Abstract:A sharp divergence has opened up in the Asia-Pacific region: Australia is witnessing a services sector boom and trade surplus, while Japan faces bond market jitters over unfunded tax cut proposals. Traders are buying AUD against the JPY to exploit this fundamental split.

SYDNEY/TOKYO — A clear fundamental divergence is emerging in the Asia-Pacific currency pairs, creating a compelling narrative for AUD/JPY bulls. While Australia reports robust economic activity, Japan is grappling with fiscal credibility concerns likened to the UK's “Truss shock.”
The Australian Dollar (AUD) has found solid footing above 0.6970 against the Greenback, driven by strong domestic data. The JanuaryServices PMI surged to a four-year high of 56.3, indicating that the domestic economy is accelerating despite global headwinds. Coupled with a widening Trade Surplus of AUD 3.37 billion, the Reserve Bank of Australia (RBA) retains legitimate hawkish cover to hold rates higher for longer.
Conversely, the Japanese Yen (JPY) is under pressure from fiscal policy risks. Prime Minister Sanae Takaichis proposal for temporary tax cuts has spooked the Japanese Government Bond (JGB) market, raising fears of unfunded spending sprees. The upcoming 30-yearJGB auction is viewed as a critical test of investor appetite.
Market participants are concerned that aggressive fiscal expansion, without a credible funding plan, could force the Bank of Japan into an uncomfortable corner—either monetizing debt or allowing yields to spike aggressively. This uncertainty is fueling a “sell on rallies” mentality for the Yen, particularly against currencies backed by strong yield and growth data like the Aussie.
