The Aussie as a China Proxy
Australia sends roughly a third of its exports to China, and iron ore alone has topped 100 billion Australian dollars in annual shipments in recent years. That makes AUD/USD the most liquid China-growth proxy available to retail traders. When Beijing stimulates construction and steel output, ore rises and the Aussie follows within days, sometimes within hours.
Expectations price ahead of the data. Ore peaked near 230 dollars a tonne in 2021, collapsed under 80 during the 2022 China slowdown, then ranged between roughly 90 and 140 through 2024 before sagging beneath 100 in 2025 as property demand stayed weak. Each leg left footprints on the exchange rate.
RBA Meetings and the Cash Rate
The Reserve Bank of Australia meets eight times a year and moves in deliberate steps. It raised the cash rate off an emergency-low 0.1 percent beginning in May 2022, reaching 4.35 percent by November 2023, held through most of 2024, then cut to 4.10 percent in February 2025. Press conferences from Governor Michele Bullock reprice the pair within a sentence or two.
Aussie expectations also answer to global risk appetite. During equity selloffs the market prices emergency RBA cuts regardless of domestic strength, which is why AUD/USD can fall on a robust Australian jobs report if the session turns risk-off. Commentary from BHP and Rio Tinto on Chinese steel demand moves the currency on publication days, free research for anyone watching.
Levels That Frame the Pair
Recent history supplies clean reference points. The post-pandemic recovery printed 0.8 in February 2021, the 2022 selloff bottomed at 0.6 in October, and 2024 chopped between roughly 0.6 and 0.7. Visits toward the mid-0.63s found dip buyers aligned with ore support, while breaks lower accelerated once China data disappointed. Spikes through 0.67 during 2024 repeatedly faded when ore stalled beneath 120, a pattern worth marking on any multi-year chart.
The Copper Link
Rolling correlation between AUD/USD and copper futures typically runs plus 0.6 to plus 0.8 on monthly windows, one of the tightest commodity-FX relationships anywhere. Copper leads slightly because COMEX contracts reprice Chinese manufacturing PMI within minutes of release, earning its nickname as the metal with a doctorate in growth.
MongkolFX charts that overlay copper on the Aussie expose divergence fast. When copper prints a new weekly high and AUD/USD stalls, either the metal rolls over or the currency is coiled for catch-up, and the gap usually resolves within three to five sessions in the direction copper signaled.
Session Timing and Data Landmines
Asian hours bring the Aussie to life, especially 9:00 am to 3:00 pm Tokyo time, with daily range averaging near 60 to 80 pips. Key events cluster tightly: Chinese official PMI on the first day of each month, Caixin PMI the following morning, Australian monthly CPI around the fourth week, and labor force data mid-month at 11:30 am Sydney time. Public holidays in Japan and China routinely cut liquidity in half, so check the regional calendar before sizing anything aggressive overnight.
Chinese releases dropping at 11:45 am Beijing time can gap the pair several pips instantly, and spreads widen a minute beforehand on MongkolFX as elsewhere. Quoting tightens again once London arrives, though volume on this pair never quite matches the Tokyo session.
What to Do With It
Anchor the trading week on three inputs: iron ore futures direction, the copper divergence check, and the RBA or China calendar. Work Tokyo hours for movement, cut size ahead of Chinese data drops, and treat the mid-0.63s as a level demanding respect until it breaks with conviction. Cut losers at ore-driven invalidation rather than waiting for the exchange rate to catch on; follow the commodities and the Aussie does the rest.
