(March 11): Taiwan’s largest life insurers are braced for a multi-billion dollar erosion in book value as the industry transitions to a more rigorous accounting framework.
Cathay Life Insurance Co, the island’s biggest insurance firm, said on Wednesday that its net asset value — defined as assets minus liabilities — will decline by NT$245 billion after adopting the new accounting standards. Nan Shan Life Insurance Co’s net asset value will fall by NT$63 billion under the new framework, according to a company announcement last week.
“The decline is primarily driven by legacy policies with a high 6% guaranteed rate, which must now be valued against lower prevailing interest rates,” said Lin Chao-ting, president of Cathay Life. “This will result in a one-off hit to our net worth.”
Taiwan’s US$1 trillion life insurance industry is transitioning this year to a stricter accounting regime that requires insurers to value their liabilities using real-time market rates — a shift that injects greater volatility into their balance sheets.
Cathay Life will also reclassify 41% of its bond holdings under amortised cost — a category that does not require mark-to-market valuations as they were meant to be held to maturity, compared with 63% previously.
The firm expects its future expected profits from insurance policies to increase year by year, with a compound annual growth of 10%, said Lin. “We will be able to withstand volatilities in net worth.”
For years, the previous framework allowed Taiwanese insurers to measure liabilities using locked-in rates set at policy issuance. While that approach provided earnings stability, it also obscured embedded interest-rate risks and left financial statements increasingly disconnected from market reality.

Nan Shan Life said in a statement that falling Taiwan dollar interest rates in 2025 “led to a significant increase in policy reserves, adversely affecting net worth”, adding that the impact was largely an unrealised valuation adjustment rather than an actual loss.
“As liabilities will continue to be measured using prevailing market rates, any future reversal in interest rates would help reduce this negative effect,” the company said.
KGI Life Insurance Co, a smaller insurance firm, saw its net worth rise by NT$14 billion under new accounting rules. Other Taiwanese insurers have not yet released information on how the new standards will affect their balance sheets.

Equity holdings are set to become another source of book-value fluctuations, as future capital gains or losses will flow directly through the insurers’ balance sheets. Moreover, interest rate movements do not affect equity valuations in the same way they revalue insurance liabilities, creating the potential for asset-liability mismatches.
Taiwanese insurers held around 11% to 13% of their total investments in stock-related instruments, according to estimates by Taiwan Ratings.
“How insurers mitigate some of these volatilities by strengthening their asset-liability management will be crucial,” said Patty Wang, an analyst on financial firms at Taiwan Ratings. “They need to identify an appropriate asset mix that can better offset the valuation swings arising from movements in both Taiwan and US interest rates.”
