The compliance certificate lands on the relationship manager’s desk. Two of the borrower’s three sustainability performance targets have been missed, and the margin step-up is already written into the facility agreement.
The mechanics are settled. What happens after them usually isn’t. According to the Loan Market Association, its updated draft provisions for
sustainability-linked loans, published on 18 August 2026, widen the triggers for declassification to include breaches that continue for a prolonged period. The guardrails are tightening; the conversation around them hasn’t caught up.
Covenant Design Decides the Conversation Before It Starts
In practice, a first miss is usually treated as a pricing event. The margin ratchets up and the relationship carries on.
That works once. Miss the same target two years running and the bank has to decide whether the loan still deserves its label. Facilities that answer that question in advance tend to share three features:
- Targets calibrated against the borrower’s own reported baseline, not a sector average
- A clear amendment route if the business changes shape through an acquisition, disposal or new site
- An agreed definition of “prolonged” before anyone needs it
Three Remediation Paths, Three Different Outcomes
Price it and move on
The step-up applies and nothing else changes. That’s proportionate for a near miss, but it tells the bank nothing about why it happened.
Reset the target
If the original baseline was wrong or the business has changed, renegotiating the KPI can be the honest answer. It only holds up if the bank can show the reset reflects evidence rather than convenience.
Declassify
The facility loses its sustainability-linked status and becomes a conventional loan. That protects the bank’s labelling integrity, but it also ends the incentive that was meant to drive the borrower’s transition.
The Conversation Nobody Has Scripted
The hardest part is the meeting where a relationship manager asks an SME owner whether the miss came from performance, from data, or from a target that no longer fits the business.
Too often, the RM arrives with one data point per year: the certificate. Without the evidence trail behind it, there is no way to tell a business that is drifting from one that simply measured differently this year.
That is a Data Gap problem, not a relationship problem. SME transition data exists, but it is often fragmented across invoices, spreadsheets and annual returns rather than streamlined into anything a bank can track.
Earlier Evidence, Better Outcomes
The Climate Action platform, developed and deployed by NatWest and National Australia Bank, is built on TDH’s sustainability intelligence and powered by FourTwoThree. SME customers get a structured way to build and maintain their transition profile, and the bank gets consistent data from the same borrower over time.
A slipping trajectory can then surface before the test date rather than at it. The remediation conversation starts earlier, runs on shared evidence and is far more likely to end with a target that is still met.
