Figure 10. Thailand: Interest Rate Risk in the Banking Book—Impact on EVE and NII
1
Sensitivity analyses indicate the impact of interest rate shocks is relatively contained.
Six standard scenarios envisaged in the Basel standard
are used, including parallel shocks…
…different types of yield curve inversion…
…and shocks concentrated in the short-end of the
curve.
While the EVE impact, in terms of Tier 1 capital, of
parallel shocks is within the suggested threshold
(-15 percent) for all bank…
… non-parallel shocks generate a smaller impact.
For NII, parallel shocks cause impacts of different sign
across banks, but all within the size of existing capital
surplus above requirements/buffers.

Basel Committee on Banking Supervision, “Interest rate risk in the banking book,” April 2016. The impact on NII was estimated
within a 1-year horizon based on two ‘parallel shock’ scenarios. The impact on EVE was estimated under the
six scenarios
envisaged by the Basel standard: (i) a parallel shock up; (ii) a parallel shock down; (iii) a steepener shock (short rates down and
long rates up); (iv) a flattener shock (short rates up and long rates down); (v) a short rates shock up; and (vi)
a short rates shock
down.
