ASX 200 Priced in Bitcoin AUD

What the chart shows

The numerator is the S&P/ASX 200 index level in AUD. The denominator is Bitcoin's AUD price. The ratio is therefore 'how many BTC does one ASX 200 index unit cost in AUD terms'.

Reading the chart is unusual because the absolute ratio value is meaningless in isolation (it depends on the index reference level). The interesting signal is the trajectory:

• Falling ratio = ASX 200 underperforms Bitcoin. The dominant pattern since BTC entered institutional consciousness in 2014. Each Bitcoin halving cycle (2016, 2020, 2024) has produced a step-down in the ratio.
• Flat ratio = ASX 200 keeping pace with Bitcoin. Occurred for limited stretches during BTC consolidation periods (Q3 2018, mid-2023, mid-2025).
• Rising ratio = ASX 200 outperforms Bitcoin. Less common. The 2022 BTC bear market produced the cleanest example: from the November 2021 BTC peak to the 21 November 2022 low, the ASX 200 slipped about 4 percent while BTC AUD fell about 74 percent, so the ratio rose about 3.7-fold. It happened again from August 2025 to mid-2026, when the ratio roughly doubled as Bitcoin fell.

The debasement thesis

The framing behind this chart is the 'measure things in Bitcoin' debasement thesis. The argument:

1. Fiat currency is debased over time. Australian broad money (M3) has grown far faster than real output since 2000. The currency in which prices are quoted is itself losing purchasing power.
2. This makes nominal price charts misleading. When you quote the ASX 200 in AUD and AUD itself is being inflated, the chart appears to show steady real wealth accumulation. In reality much of the rise is the measuring stick shrinking, not the asset growing.
3. Bitcoin is the hard-supply alternative. 21 million coin cap, halving-coded supply reduction every four years, no central authority. The framing is that BTC is a constant unit and everything else is being debased against it.
4. Pricing in BTC reveals 'real' performance. When you divide the ASX 200 by BTC AUD, the steady AUD uptrend converts to a steady downtrend in BTC terms. The same is true of property, gold (in BTC terms), and almost every traditional asset.

This framing is contested. Mainstream economists argue that the AUD is not 'debased' to the degree the BTC thesis implies, and that BTC's outperformance reflects adoption-curve expansion rather than fiat collapse. The framing has nonetheless become standard in Bitcoin-investor circles and informs long-horizon allocation decisions.

Why AU investors should look at the ratio

• Long-horizon wealth preservation framing. AUD-resident BTC stackers use the chart to size conviction in long-horizon BTC allocation. If the ratio continues falling, BTC has continued to outperform local equity in AUD-debasement-adjusted terms. Over 2014-2026 the BTC side has come out well ahead, though with deep drawdowns along the way.
• Asset allocation sizing. The ratio gives a 'how concentrated should I be in BTC vs equity?' anchor. Most professional financial advisors recommend BTC at 1-5 percent of portfolio. The BTC framing argues for higher allocations based on the 12-year track record of relative outperformance.
• Cost-of-living context. If you measure your standard of living in BTC (groceries, rent, super contributions), what you spend in AUD looks bigger or smaller depending on the BTC-AUD ratio. AUD-resident BTC stackers think this way explicitly; ASX 200 in BTC is the equity version of the same framing.
• Sceptic's perspective. If you are not a BTC stacker, the chart is useful as a 'what am I being told about the future' framing. The BTC-debasement view is one of three or four serious arguments for elevated BTC allocation; understanding the framing helps evaluate whether to adopt it.

Methodology

1. Numerator source. Yahoo Finance, ticker ^AXJO (S&P/ASX 200 price return index).
2. Denominator source. Our daily BTC AUD series at /assets/data/btc-aud-daily.json: Bitstamp BTC/USD daily closes converted at the daily AUD/USD rate from Yahoo Finance, with Kraken's native BTC/AUD closes for roughly the last two years. Each refresh is cross-checked against Coinbase and Kraken spot prices.
3. Ratio calculation. Daily ASX 200 close divided by daily BTC AUD close. Only days where both values are available are kept. BTC trades 365 days/year but ASX trades ~252; weekend BTC values are not used since there's no ASX print to pair with.
4. Same-currency frame. Both numerator and denominator are AUD-denominated. This keeps the ratio currency-consistent (an 'ASX 200 in BTC AUD' ratio rather than mixing AUD and USD).
5. Log scale. Y axis is log-scaled so a halving of the ratio looks the same regardless of absolute level.
6. Refresh and fallback. An automated refresh runs twice a day (07:30 and 13:30 Sydney) and the site rebuilds when the data changes. If either source is unreachable, the last good data is kept.
