Australia

Australia holds dollar reserves and settles trade in USD. Every time the Fed expands M2, that premium compounds against the AUD, on top of domestic inflation.

CPI: World Bank (FP.CPI.TOTL.ZG). US M2: Federal Reserve FRED (M2SL). Reserve premium = cumulative M2 growth − cumulative US CPI.

Australia feels like an English-speaking bargain when you first check the exchange rate. Around 2001, one US dollar bought about 50 Australian cents — Americans were basically shopping at a 50% discount. By 2011, the tables had completely flipped. The AUD hit parity with the dollar, briefly trading above it, driven by the China-fueled mining boom that sent iron ore and coal prices into the stratosphere. If you moved to Melbourne in 2008 feeling wealthy, you felt it again in 2012 in the opposite direction.

Here's the thing about the Australian dollar that most financial sites skip: it's a commodity currency. When China's economy accelerates and buys more Australian resources, the AUD strengthens. When global growth slows, the AUD drops — sometimes fast. Between 2013 and 2016, it fell roughly 30% against the USD. That's not inflation in the traditional sense, but for an American with income in dollars living in Brisbane or Perth, it meant the rent, the groceries, and the weekend trip to the Whitsundays all got cheaper overnight. The reverse is equally true.

For US investors eyeing Australian property — particularly in Sydney and Melbourne, two of the most expensive residential markets on earth — the currency layer adds real complexity. Sydney median house prices have roughly tripled since 2000 in AUD terms. But your return in USD depends entirely on where the exchange rate sits when you sell. The AUD has swung in a 40-cent range over the past two decades. That's not a rounding error; that's the difference between a great investment and a mediocre one.

Australia's inflation peaked near 8% in late 2022 and early 2023, the highest in over thirty years, before the Reserve Bank of Australia spent 2023 and 2024 aggressively hiking rates to bring it back down. The cost of living in Australian cities — already high by global standards — took a real jump during that period.
