The rating remains contingent upon WTS sustaining its capital levels, improving profitability metrics, managing interest rate risk through the cycle, and deploying leverage prudently relative to its duration-extended portfolio. An adverse and sustained movement in interest rates that results in material MTM losses, or a deterioration in the capital adequacy position, would exert downward pressure on the rating. Conversely, consistent earnings supported by disciplined portfolio and duration management, together with the build-up of additional capitalization buffers, would provide positive impetus over the medium term.
