What is RARTA?
RARTA — Risk-Aligned Return Threshold Approach — is the Satoshi Institute framework that derives a Bitcoin allocation band from reserve composition, operating-liquidity needs, and the board's defined drawdown tolerance. It replaces precedent-based percentages with a documented methodology that yields a band rather than a point estimate, and a set of rebalancing triggers when the band is breached. Full specification at /frameworks/rarta.
Why this question gets asked
Boards want a defensible allocation number. The defensible answer is a process that produces a band.
Treasury v1 asks vs. Treasury v2 asks
- What percentage should we hold?
- Which methodology produced our band, and would it still hold under stressed inputs?
“What is RARTA?”
“Which inputs — liquidity, drawdown tolerance, volatility contribution — yield the allocation band ratified in the IPS?”
Boards want a defensible allocation number. The defensible answer is a process that produces a band.
What decision-makers should watch
- Methodology documented and stored with the IPS
- Band sized to drawdown tolerance, not target return
- Sensitivity analysis re-run on each annual review
- Rebalancing triggers tied to band breach
