Japan PPI, China CPI Data Set Up Yen-Yuan Divergence Trade

Asia FX traders have two inflation readings to work through on June 10. Japan releases its producer price index. China prints both consumer and producer prices. The data set up a divergence trade between the yen and the yuan.

China CPI vs PPI: Consumer Weak, Factory Strong

China's month-on-month CPI is expected to stay subdued, per consensus forecasts. Consumer demand remains soft. Manufacturers face rising costs from three pressures. The Middle East conflict has lifted energy and raw material input prices. A surge in electronic component prices driven by the global AI investment wave feeds through. Beijing's moves to rein in overcapacity and cut-throat domestic competition tighten supply on the factory side.

The result is a PPI that stays elevated while CPI stays low. That split matters for the yuan. Low CPI gives the PBOC room to keep policy loose. That typically weighs on the currency. High PPI squeezes exporter margins. Those firms may need a weaker yuan to stay competitive. The central bank faces a balancing act between support for demand and cost pressures on producers.

Japan PPI: Pipeline Inflation Keeps BOJ on Tightening Path

Japan's producer price index will show whether pipeline inflation is still accelerating. The weak yen and higher commodity costs have kept input prices elevated. For the Bank of Japan, this is a key input. Governor Kazuo Ueda has signalled that sustained producer inflation eventually feeds into consumer prices. That justifies further rate hikes.

The market has already priced in a BOJ rate hike at the next meeting. A strong PPI print would reinforce that view. It would also support the yen, which remains under pressure from the wide rate gap with the US. Speculative short yen positions are still elevated, according to the latest weekly COT data. A hot PPI could trigger a squeeze on those shorts. The broader context is covered in a separate note on how the BOJ rate hike is priced in as FX awaits the US CPI catalyst.
