The signals a risk framework should never stop watching
A framework is only as good as the signals it tracks. SCRF watches five classes of change across global multi-asset markets. Each one answers a different part of the first principle — that the sources of risk must be explainable — and each carries a question it should prompt before any decision is made.

Five tracked signal classes
These are monitoring tracks, not forecasts. A signal notes that something has changed; the framework's job is to work out what that change means before it is treated as a reason to act.
Asset concentration
What it means: exposure has clustered into a small number of positions, sectors or factors. Concentration can hide inside a portfolio that looks broadly spread, because apparent diversity collapses when several holdings depend on the same driver.
Ask: If the dominant exposure moved against us, how much of the portfolio would move with it?
Liquidity deterioration
What it means: the market's ability to absorb trades is thinning — spreads widen, depth falls, and size that was easy to move becomes expensive to exit. Deteriorating liquidity turns a manageable position into a fragile one at exactly the wrong moment.
Ask: Could we exit this exposure at a fair price, or are we relying on liquidity that may not be there under stress?
Leverage
What it means: borrowed exposure is amplifying the portfolio's sensitivity to moves. Leverage does not create risk so much as multiply it, converting an ordinary swing into a change that can force action at the worst time.
Ask: Is the leverage in the portfolio proportionate to the opportunity, or does it leave no room for being wrong?
Abrupt correlation change
What it means: relationships that normally move apart have started to move together — often quickly. When correlation shifts, the diversification a portfolio relies on can evaporate, and assets thought to offset each other fall in the same direction.
Ask: Does our diversification still work under these new relationships, or have the offsets quietly disappeared?
Participant behaviour shifts
What it means: the composition of market participants and their behaviour is changing — positioning, crowding, risk appetite, or flows into and out of an asset class. Behaviour shifts can create new sources of risk before any price has moved to reflect them.
Ask: Who is on the other side of this position, and what happens if they all want to leave at once?
Reading
From signal to severity
A single signal is information. Severity is a judgement about how far a condition has moved from the portfolio's expected bounds — and the same signal can sit at different tiers depending on what else is moving alongside it.

Review exposure boundaries
The signals are deliberately read together, not in isolation. Concentration and leverage reinforce each other; deteriorating liquidity makes a correlation shift harder to escape; participant behaviour can move all four at once. Understanding the combination is the work — it is the difference between a warning light and a risk that is genuinely understood. The SCRF framework article sets out how these signals feed the four-step cycle from detection to adjusting exposure.
