Solvency of the banking system
29. Stress test results suggest that the banking system as a whole is sufficiently
capitalized, although the results for the two large banks are sensitive to the definition of capital
(Figure 7). Using the current Core Tier 1 capital definition (i.e., allowing
for the phase-in transition
period embedded in Basel III rules) as starting point, these banks’ capital
ratios comfortably exceed
capital requirements under all scenarios, and capital does not fall below the 7 percent threshold.
However, under the most severe macroeconomic scenario (Adverse Scenario 2), using the “fully
loaded” common equity tier 1 (CET1) capital 2019 definition (under Basel III),
capital ratios could
fall below the 7 percent threshold.

These results suggest that the systemic banks are well placed
vis-à-vis
the introduction of Basel III, but should continue decisively with their capital build-up to
further enhance their resilience (Figure 8).
