A fundamental shift in how Taiwan's life insurers manage their $700 billion overseas portfolio is reinforcing the island's position as a key global bond investor, strategists say.
New accounting rules that came into effect this year have changed the math for Taiwan's insurers, who must routinely seek higher returns abroad to compensate for a domestic market with limited depth.
Previously, a rise in the local dollar meant an immediate earnings hit, a risk they spent billions to hedge. The new framework allows them to buffer these shifts by spreading currency gains and losses over the life of the bond, making it easier to hold foreign debt without the pressure to pay for costly market protection.
Empowered by this change, insurers have cut protection against a stronger local currency to historic lows, a move that's also upending market dynamics. Reduced hedging is removing a primary source of liquidity from offshore derivatives.
Understanding the global impact:
What is the scale of Taiwan's global bond footprint?
Taiwan as a whole owns $1.04 trillion of foreign bonds, ranking eighth globally in such holdings excluding major financial centers, according to Bloomberg-compiled data.
That's equivalent to 129% of the island's nominal gross domestic product, more than double Japan's ratio. While Norway's ratio is higher, it's mostly driven by the nation's sovereign wealth fund.
Taiwan's footprint is unique as it's led by life insurers who held $724.7 billion in overseas assets at year-end, equivalent to roughly a quarter of the island's total foreign portfolio investment. Foreign investments made up two thirds of insurers' total invested capital, underscoring the importance of currency management for these investors.
"Foreign investments for Taiwanese lifers will continue to remain high," said Chidu Narayanan, head of macro strategy for Asia Pacific at Wells Fargo in Singapore, citing the island's shallow domestic markets. "While the composition of foreign investments might evolve, overall, foreign investments are likely to remain the bulk of lifer assets."
For Serene Hsieh, a credit analyst at Taiwan Ratings Corp., foreign bonds will remain a "keystone" of insurers' portfolios to better manage interest-rate risks and regulatory capital.
Why are Taiwanese life insurers cutting FX hedging?
The move is mainly driven by a regulatory change that allows insurers to spread out any gains or losses from exchange-rate changes over a bond's remaining life, rather than recognizing them immediately.
Consequently, currency hedging covered 45.1% of life insurers' overseas assets in February, an all-time low, according to the latest Financial Supervisory Commission data. While the official reading began in January 2024, Bloomberg analysis shows the ratio was as high as 74% in 2018.
A similar drop was seen in Japan, where life insurers cut the hedging ratio to 46% as of end-September from more than 60% in 2020, as the yen weakened and hedging costs stayed high.
Hedging can be expensive for Taiwan's insurers because the cost is driven by the interest rate gap between local and foreign markets. This burden becomes more punitive during the local currency's surge, as seen last year when a historic rally in the Taiwan dollar forced insurers to either pay exorbitant costs for protection or report massive paper losses on their holdings.
The new hedging rules were designed specifically to prevent this kind of market panic.
The three-month dollar hedging costs for Taiwanese life insurers surged to nearly 14% in May 2025 before plunging to negative 1% as the demand eased.
Rather than paying for market protection, Taiwan's regulators are urging insurers to funnel savings into foreign-exchange valuation reserves, which are internal buffers to absorb currency shocks. However, Taiwan Ratings Corp. warned last week that so far these reserves remain insufficient in case of a sudden 10% currency appreciation in the local dollar.
How is the hedging reduction affecting markets?
The impact is most visible in the offshore forward markets, where traders lock in future exchange rates. For the first time since 2016, a key market signal has flipped, indicating that insurers' massive demand to hedge US dollars has nearly vanished.
Currency hedging by Taiwanese life insurers -- which involves selling foreign currencies to buy the local dollar -- has declined. That's eased the appreciation pressure on the Taiwan dollar.
Bloomberg Intelligence analyst Steven Lam cautions that the retreat from swaps and non-deliverable forwards could thin market liquidity marginally. "If insurers need to increase hedges in the future they might face steeper costs."
Regardless of the shift in hedging dynamics, the currency remains well supported by the island's hefty current-account surplus, as exporters continue to bring home a steady stream of overseas earnings.
The Taiwan dollar jumped over 4% last year, the most since 2020, but has since retreated about 1% against the US currency.
Are insurers likely to further reduce hedging?
A further drop is unlikely.
Fubon Life Insurance Co.Bloomberg Terminal said last month that its hedge ratio will stay steady in the near term, while Shin Kong Life Insurance Co.Bloomberg Terminal said it will maintain the ratio near 50%. Cathay Life Insurance Co.Bloomberg Terminal has said hedges using offshore forwards was almost zero.
A separate transition to a stricter capital regime could also discourage insurers from fully abandoning hedging, as unhedged assets would be subject to capital charges.
"We do not expect hedge ratio to decline significantly from the current level," Kiyong Seong, lead Asia macro strategist at Societe Generale in Hong Kong," wrote in a research note."Lifers' FX hedging adjustment is nearing completion."
