The OSI measures Bitcoin miner stress across $0.03, $0.06, and $0.09/kWh electricity tiers to show which operators are squeezed at current hashprice.
Frequently asked questions
What does the Operator Stress Index measure?
The OSI measures how stressed Bitcoin miners are at three different power-cost tiers — $0.03, $0.06, and $0.09/kWh — by comparing current hashprice against break-even costs for a representative modern ASIC at each rate.
Why are there three OSI scenarios?
Different mining operations have very different power costs. Splitting into $0.03 (low-cost industrial and stranded power), $0.06 (mid-tier hosted), and $0.09/kWh (high-cost or retail) shows exactly which cohort is squeezed first as hashprice falls.
What does a high OSI score mean?
A higher OSI score means more operators at that electricity rate are underwater or close to their shutdown price. If the $0.09/kWh OSI is red while $0.03/kWh is green, only high-cost miners are stressed.
How often is the OSI updated?
The OSI is recomputed hourly alongside the MCR by the compute-indexes pipeline and stored in index_timeseries for historical charts and embeddable widgets.
