Taiwan Life Insurers: The Currency Risk Behind $724 Billion

At the end of 2025, Taiwan’s life insurers held NT$37.68 trillion in assets, equivalent to 131.22% of the island’s GDP. Foreign investments accounted for 60.42% of that balance sheet, or roughly $724 billion at the year-end exchange rate. That number measures a stock of assets, not a possible loss. The risk lies in the gap between assets heavily invested abroad and liabilities that remain predominantly denominated in New Taiwan dollars. In 2025, an appreciation of the TWD turned that mismatch into a live stress test. The reforms that took effect in 2026 build reserves, change solvency measurement and defer the recognition of some foreign-exchange effects. They do not remove the underlying economic exposure.

$724 billion abroad does not mean $724 billion at risk

The starting point is the Central Bank of the Republic of China (Taiwan)’s 20th Financial Stability Report, released on 29 May 2026. At the end of 2025, Taiwan’s life insurance sector reported NT$37.68 trillion in assets. The central bank states that foreign investments represented 60.42% of total assets, compared with 17.53% for domestic securities.

That produces NT$22.766 trillion in foreign investments. Converted at the 31 December 2025 interbank closing rate of NT$31.438 per US dollar, the amount is approximately $724.2 billion. This is an l0g calculation based on two official data points. It is not a fully dollar-denominated portfolio, an open FX position or a loss estimate.

The distinction matters. A foreign asset may be hedged with a derivative, matched by a foreign-currency liability, classified so that its currency valuation does not immediately run through profit and loss, or denominated in a currency other than the US dollar. The $724 billion figure describes the scale of the machine, not its net sensitivity.

The sector is also concentrated. At end-2025, 19 domestic insurers accounted for 99% of assets. Cathay Life held 23.87%, Fubon Life 15.67% and Nan Shan Life 14.80%. The three largest firms therefore controlled 54.34% of the market. Currency risk is not distributed uniformly across them, but a common shock reaches systemically important institutions.

Why Taiwan’s life insurance sector invested so heavily abroad

The mechanism was built over decades. Life insurers collect premiums and promise long-term benefits. They need sufficiently long and sufficiently remunerative assets to meet those liabilities. The domestic bond market does not always provide all the depth, duration and yield they seek. The same asset-liability logic is central to our guide to reading a life insurer’s financial health.

The IMF described this trend in 2019 across Japan, South Korea and Taiwan: legacy return guarantees above local yields, duration mismatches and relatively small domestic credit markets encouraged life insurers to search for yield abroad. The IMF estimated that Taiwanese life insurers added roughly $250 billion of US-dollar credit between 2013 and 2018. That historical estimate does not describe today’s portfolio composition, but it documents the structural origins of the model.

Recent central-bank data show how large it has become. At end-2025, the sector’s investment position stood at NT$30.34 trillion, with securities as the predominant asset class. Foreign investments accounted for more than three fifths of all assets.

The model must manage three constraints: investment income, the change in asset prices when interest rates move, and the exchange rate between the assets and the insurance contracts. The third becomes most visible when the TWD appreciates. A $100 asset is then worth fewer Taiwan dollars even when the issuer pays exactly what was promised.

The currency mismatch is not a simple subtraction

The central bank reports that foreign-currency policy liabilities represented 19.49% of assets at end-2025, far below the 60.42% foreign-investment share. The raw difference is 40.93 percentage points. It is a warning signal, not a complete exposure measure.

The Financial Supervisory Commission’s rules on foreign-exchange reserves, revised on 13 February 2026, explain why. To calculate the “net foreign investment exposure,” the regulator starts with total foreign investments and deducts, among other items:

1. liabilities from non-investment-linked policies whose receipts and payments are denominated in foreign currencies;
2. certain unhedged equities and funds whose FX valuation does not affect profit and loss;
3. principal covered by traditional hedges;
4. other items approved by the supervisor.

The same regulation defines traditional hedges as FX forwards, swaps, cross-currency interest-rate swaps and non-deliverable forwards. The official hedge ratio is therefore a specific regulatory calculation. It is not the percentage of every foreign asset that would be perfectly protected in every scenario.

The central bank also says insurers use basket-currency hedges. These can reduce part of the risk, but they introduce basis risk: the proxy currency or instrument may not move exactly like the exposure it is intended to offset.

2025 turned the spreadsheet risk into a live test

In 2025, the TWD appreciated 4.27% against the US dollar, moving from NT$32.781 per dollar at end-2024 to NT$31.438 at end-2025. According to the central bank, this generated a gross foreign-exchange loss of NT$548.5 billion on the sector’s net foreign assets.

Hedges offset only a small part of that shock at aggregate level. The report breaks out NT$292.2 billion in swap and hedging costs and NT$349.6 billion in gains on hedging instruments, producing a net hedging benefit of NT$57.4 billion.

These figures do not form a profit bridge that can simply be added to pre-tax income. Reserve movements, other investment income, valuation effects and accounting rules also intervene. They nevertheless show the asymmetry: a hedge can gain when the TWD rises while remaining very expensive to carry because of the interest-rate gap between Taiwan and the United States. The cross-currency basis helps separate this dollar-funding premium from the headline policy-rate differential.

Sector pre-tax profit fell to NT$156.9 billion, from NT$315.5 billion in 2024, a decline of 50.25%. Average return on equity dropped from 13.06% to 5.92%, while return on assets fell from 0.88% to 0.42%.

At end-2025, the regulatory FX hedge ratio had fallen to 50.23%, an all-time low. At the same time, the foreign-exchange valuation reserve reached a record NT$613.7 billion.

This is not the balance sheet of a sector already in collapse. The average legacy RBC ratio still stood at 315.09%, down from 331.95% a year earlier. Thirteen insurers were above 300%, while two remained below the old 200% legal threshold. The equity-to-assets ratio excluding separate accounts rose from 7.62% to 7.86%, although one institution remained below the 3% minimum. The central bank concluded that Taiwan’s financial system remained stable overall while identifying life insurers as exposed to elevated market risks.

Two trading sessions showed how fast the risk can move

Annual figures hide the violence of short episodes. The official closing rate moved from NT$32.017 per dollar on 30 April 2025 to NT$31.064 on 2 May and NT$30.145 on 5 May. Because fewer Taiwan dollars were needed to buy one US dollar, this amounted to a 6.21% TWD appreciation over two trading sessions, according to an l0g calculation.

The Financial Stability Report attributes the second-quarter move to capital inflows into Taiwanese equities, combined with increased dollar supply from exporters expecting the TWD to appreciate. The central bank later confirmed that it intervened in May 2025 to maintain order in the foreign-exchange market.

Nothing in these data proves that insurers caused the move. They do show how quickly a mismatch accumulated over years can generate earnings volatility, hedging needs and portfolio adjustments.

Hedging is expensive, but remaining unhedged can be more expensive

A Taiwan insurer holding a dollar asset can buy a forward hedge or enter a swap. The transaction fixes, or narrows the uncertainty around, the rate at which future dollars will be converted into TWD. It reduces the currency surprise, but it is not free.

When US short-term rates are far above Taiwan’s rates, hedging the dollar against the TWD incorporates that differential. The central bank explicitly states that the Taiwan-US rate gap remained wide in 2025 and kept hedging costs elevated.

That creates an uncomfortable trade-off:

• raising hedge ratios protects the balance sheet but reduces net investment income;
• lowering hedge ratios preserves more bond carry but increases sensitivity to TWD appreciation;
• basket hedges may be cheaper but leave a gap between the proxy and the actual currency exposure;
• selling or repatriating assets reduces future exposure but may realize interest-rate, credit or currency losses.

The BIS noted in 2021 that Taiwanese insurers hedged roughly half of their foreign bond holdings, compared with ratios often close to 100% in South Korea and Thailand. The comparison is historical and methodologically different, but it shows that Taiwan’s partial-hedging model was not created by the 2025 shock. The official 50.23% ratio at end-2025 confirms that it remains central to the system.

2026 brought three reforms aimed at different problems

From 1 January 2026, Taiwan’s insurers simultaneously adopted IFRS 17 for insurance contracts and TW-ICS, the new solvency regime based on the IAIS Insurance Capital Standard. In February, the regulator also rewrote the treatment of some FX differences and the reserve framework.

The three blocks are often discussed as one reform. They answer different questions.

IFRS 17: how insurance liabilities are measured

IFRS 17 changes the measurement and presentation of insurance contracts. Liabilities are more explicitly linked to future cash flows, discounting and financial risks. Taiwan’s transition is particularly sensitive because of legacy contracts with high guaranteed rates.

The Insurance Bureau announced in 2023 a 50-basis-point liquidity adjustment for certain TWD policies sold before 1 January 2004 with reserve rates of at least 6%. That measure addresses the valuation of inherited liabilities. It does not hedge the foreign asset portfolio.

TW-ICS: how much capital is needed to absorb risk

TW-ICS replaces the former RBC framework. The formal capital-adequacy threshold moves from 200% to 100%, but the numbers are not directly comparable because both the capital definition and the risk perimeter change. The new regime adds non-default spread risk, longevity risk, lapse risk, expense risk and catastrophe risk.

The transition may run from January 2026 through December 2040. According to the central bank, interest-rate risk can be recognized from at least 50% in the first year before rising linearly to 100%. Some newly introduced risks may start at 0% and rise to 100%. A separate net-asset transition spreads the capital impact of legacy high-guarantee TWD policies.

A 15-year adjustment period can prevent a disorderly portfolio shift. It also means that a transitional TW-ICS ratio must be read together with the relief measures rather than treated as a fully loaded 2026 snapshot.

New reserves: building buffers when insurers hedge less

The 13 February 2026 regulation splits the FX reserve into a volatility reserve and a fixed reserve. The fixed reserve is funded monthly according to net foreign investment exposure, with a cumulative cap equal to 10% of that exposure.

The rules also create two special reserves out of earnings. In principle, 10% of after-tax profit is allocated to a fixed FX-risk reserve. An enhanced reserve is calculated from the shortfall between an insurer’s hedge ratio and a reference ratio, multiplied by a regulatory hedging-cost assumption set at 2.5% unless the supervisor decides otherwise. The enhanced reserve normally cannot be used to pay cash dividends.

The logic is clear: an insurer choosing to hedge less must retain more earnings. The reserve is still not an FX contract. It absorbs financial consequences; it does not change the TWD-dollar rate.

Smoothing an FX difference is not the same as buying a hedge

The most delicate accounting change appears in the Regulations Governing the Preparation of Financial Reports by Insurance Enterprises, amended on 5 February 2026 and applicable from fiscal 2026.

When an insurer concludes that the conditions in IAS 1 are met, it may apply a special treatment to certain directly held debt instruments measured at amortized cost whose foreign-currency risk has not been designated as a hedged item. The unrealized FX difference on each instrument may be amortized on a straight-line basis over its expected remaining duration. The unamortized balance is reported in other assets or other liabilities. When the instrument is derecognized, the entire remaining amount is recognized in current-period FX profit or loss.

This treatment may align accounting timing more closely with the economic horizon of an insurer intending to hold a bond to maturity. It can also make earnings harder to compare: two firms exposed to the same currency move may report different timing profiles depending on asset classification and use of the rule.

The central bank states the limitation directly. The new reserve framework and accounting adjustments may smooth life insurers’ earnings volatility, but they do not reduce the underlying currency mismatch. With hedge ratios falling, the risk persists and could still have a significant earnings impact under an extreme exchange-rate scenario.

From chips to foreign securities: a macro loop, not dollar-by-dollar tracing

Taiwan accumulates claims on the rest of the world because its economy generates a very large external surplus. In 2025, the current-account surplus reached $181.14 billion. The financial account recorded a $157.16 billion net increase in assets, while official reserve assets increased by $20.04 billion.

The dynamic continued in 2026. Over the first two quarters, the central bank recorded a $121.03 billion current-account surplus and a $118.12 billion net increase in financial-account assets. In the second quarter alone, it attributed the wider goods surplus to strong demand for emerging-technology applications.

The central bank also explains the accounting link: when a country earns more from goods, services and income than it spends abroad, its net claims on the rest of the world must rise. Those claims may be held by the private sector or by the central bank. At end-2025, Taiwan’s international investment position included $3.267 trillion in external assets, $1.9174 trillion in liabilities and a net asset position of $1.3496 trillion. The CBC ranked Taiwan as the world’s sixth-largest net creditor.

“From chips to bonds” is therefore a valid macroeconomic shorthand only if it is not turned into a fictional ledger. Balance-of-payments statistics do not show that a dollar received by TSMC or a server maker is subsequently invested, unchanged, by Cathay Life or Fubon Life. They show that the economy generates excess saving over domestic investment, and that the excess is reflected in foreign-asset accumulation.

Why global markets should watch Taipei

Taiwan’s life insurers are not only exposed to global markets; their scale also makes them participants in those markets. The Financial Stability Report says the sector’s NT$30.34 trillion investment position consists mainly of securities. Public sector-wide data do not provide a complete, consistent end-2025 breakdown by country, currency, issuer and debt category. It would therefore be wrong to describe the full $724 billion as a portfolio of US Treasuries.

The IMF’s 2019 work nevertheless showed that Taiwanese life insurers had become important buyers of dollar credit. The BIS later documented the role of Asian institutional investors in generating dollar funding demand through FX swaps and other derivatives.

Three transmission channels deserve attention.

The bond channel. Even a marginal reallocation of a several-hundred-billion-dollar portfolio can affect demand in specific maturities or credit segments. The effect depends on asset composition, which must be verified in each insurer’s accounts.

The derivatives channel. Hedges must be rolled. Their price and availability depend on swap, forward and dollar-funding markets. A lower hedge ratio reduces immediate derivatives demand but raises balance-sheet sensitivity to the TWD.

The prudential channel. A loss, a higher capital charge or an enhanced reserve can constrain dividends, slow new asset purchases or force a group to raise capital. Transmission then occurs through portfolio behaviour rather than an instant forced sale.

Four scenarios for understanding the risk

1. A stable or weaker TWD

Translation pressure eases and reserves can be rebuilt. Dollar assets are worth more in TWD. Hedging costs may remain high if the rate gap with the United States stays wide. A favourable currency move does not solve the portfolio’s interest-rate or credit risk.

2. Gradual TWD appreciation

Translation losses accumulate more slowly. Reserves and the new accounting treatment can smooth reported earnings. The balance sheet still deteriorates in TWD terms if appreciation persists and hedge gains do not offset instrument costs.

3. A sharp TWD appreciation

The May 2025 move shows the speed that is possible. Hedges gain value, but their effectiveness depends on the covered share, maturities and basis risk. Margin requirements, swap rollovers and liquidity become more important, without making a crisis automatic.

4. A stronger TWD combined with a bond sell-off

This is the most demanding combination: local-currency values fall while higher yields or wider spreads reduce bond prices. If policy lapses or liquidity needs require sales, unrealized losses can be crystallized. TW-ICS explicitly adds more interest-rate, spread and lapse risk, although part of the capital charge is phased in during the transition.

These scenarios are not forecasts. They isolate mechanisms so that a real vulnerability is not converted into a crisis prophecy.

The indicators that now matter

The $724 billion figure will move with asset purchases, market prices and the exchange rate. A serious risk assessment should focus on:

The foreign-investment share. It measures dependence on overseas markets but does not, by itself, give the currency exposure.

Foreign-currency policy liabilities. They provide natural matching and should be compared by currency and duration with the assets.

The traditional hedge ratio. A decline lowers current cost but raises TWD sensitivity. Its regulatory definition must accompany any comparison.

The TWD-dollar swap cost. It determines the price of protection and can quickly change the trade-off between income and safety.

Volatility, fixed and enhanced reserves. Their size indicates both loss-absorption capacity and the share of earnings locked away.

TW-ICS before and after transition measures. A single published ratio without the transition detail may provide an incomplete picture.

The classification and duration of amortized-cost debt. These determine how much FX difference can be deferred and how much could return immediately to profit and loss upon a sale.

Conclusions supported by the evidence

The $724 billion figure describes an enormous foreign portfolio held by a sector whose assets exceed Taiwan’s GDP. It does not describe a $724 billion bomb. Vulnerability depends on each asset’s currency, matching liabilities, derivatives, hedging costs, reserves, capital and the ability to hold securities to maturity.

The 2025 data nevertheless provide hard evidence of sensitivity: a 4.27% annual TWD appreciation coincided with NT$548.5 billion in gross FX losses and a halving of sector pre-tax profit. The sector still had a high average capital ratio and a record reserve. The central issue is therefore less an immediate insolvency claim than the possibility of repeated, expensive shocks hitting a structurally mismatched balance sheet.

The 2026 reforms address the issue through three routes: more economic insurance-liability measurement, a broader capital framework and additional buffers when insurers cut hedges. Deferring some FX differences buys time. Time is useful only if it is used to improve currency matching, capital and liquidity.

The question for the coming years is easy to state and difficult to solve: can Taiwan preserve the income from its foreign assets without making the stability of its life insurance sector depend on a TWD that must never appreciate too quickly?
