NGFS guidance: central banks can use capital buffers to manage climate risks

Central banks are being urged to consider capital buffers on loans to high-emitting sectors and on mortgages in climate-vulnerable areas, according to new guidance from the Network for Greening the Financial System (NGFS). The updated guide, released during New York Climate Week, outlines tools like adjusted loan-to-value limits and green lending terms to manage systemic climate risk. It also stresses that implementation should be tailored to each jurisdiction's mandate and legal framework. The guide expands beyond transition risk, pushing supervisors to monitor physical risks like flooding and heat, and to track the insurance protection gap. It introduces key risk indicators including financed emissions and ecosystem dependencies. While the NGFS stops short of prescribing a one-size-fits-all approach, the guidance gives central banks a practical roadmap for integrating climate and nature risks into prudential supervision.

Interesting move from NGFS. Capital buffers on high-emitting loans could actually push banks to price carbon risk properly. But the real test is how supervisors implement this without breaking the economy. The guidance says 'proportionately', which is vague. Any idea what that means in practice?

The insurance protection gap point is key. If people aren't insured, banks eat the losses. Using LTV limits for green assets is smart, but only if they don't just shift risk to other sectors. Curious to see how this plays out in the US where the Fed left the NGFS.

Capital buffers on mortgage portfolios in flood-prone areas make sense, but the data needed to assess that is a mess. How do you verify which properties are actually at risk? The NGFS mentions key risk indicators, but the real issue is data quality and sharing. Without that, these buffers are just guesswork.

The guide is more practical than the 2020 version, but still lacks teeth. It says 'should' not 'must'. Central banks have different mandates, so this will be uneven. Also, the Fed bailed, so how effective can this really be globally?

The key is that this is a roadmap, not a template. That's sensible. But the transition risk buffer on high-emitting sectors could be a double-edged sword. If applied too aggressively, it might trigger firesales. The NGFS should be careful about procyclicality. Still, it's a step forward.

LTV adjustments for green assets like energy efficiency improvements sound good, but the payback periods are long. Banks need to see that these assets hold value. Also, the guide mentions ecosystem dependencies, but that's still very early. Practical implementation will take years.
