Basel 3.1 is fundamentally altering
how banks manage capital, shifting the focus from model-driven optimization to
a more complex framework built on data discipline, governance, and
comparability across multiple regulatory lenses.
According to Sajid Iqbal, Head of
Financial Risk & ICAAPO at Habib Bank AG Zurich, the reforms mark a
decisive break from previous regulatory cycles.
“Basel 3.1 is shifting capital
management away from being largely a model optimization exercise and towards a
data, governance, and comparability discipline,” he said, highlighting the
growing importance of managing capital across internal models, standardized
approaches, and output floors simultaneously.
This multi-dimensional approach is
bringing capital strategy closer to day-to-day business decisions.
Product pricing, hedging strategies,
and portfolio construction must now reflect whichever regulatory constraint is
binding at a given time, rather than relying on internal models as the primary
driver of capital efficiency.
At the same time, global banks are
grappling with significant implementation challenges, particularly those
operating across multiple jurisdictions.
Iqbal described the environment as
one of “parallel regulatory realities,” where differing timelines, supervisory
expectations, and interpretations create operational friction.
These challenges are most evident in
consolidated versus local capital planning, internal capital allocation, and
data architecture.
Firms are required to maintain
consistent data definitions even as regulators emphasize different priorities,
increasing the complexity of reporting and governance frameworks.
The evolving treatment of
risk-weighted assets is also reshaping capital planning decisions.
As model-based benefits diminish
under tighter constraints and output floors, banks are increasingly adopting a
portfolio engineering approach.
“Capital planning is shifting towards
portfolio engineering, relying less on model-based benefits,” Iqbal said.
This shift is driving institutions to
simplify portfolios where complexity no longer delivers value, while
redesigning or repricing products that attract higher standardized capital
charges.
In parallel, firms are moving toward
regime-based planning, taking into account how changes in interest rates,
market volatility, and liquidity conditions influence core capital drivers.
