Ballast No More: What a Rising Term Premium Means for Fixed Income Held in Two Currencies

Thirty years compressed into one number

Japan’s 10-year government bond yield reached 3% for the first time since 1996. It is tempting to file that under foreign news, and most Canadian and American households will never own a Japanese government bond. File it somewhere else.

A yield level that has not been seen in three decades is not a trading range being tested. It is a marker that something structural has changed, and Japan is the clearest case because it spent longer than anyone at the opposite extreme. For most of the last thirty years, Japanese government debt was the anchor for the global assumption that safe assets pay very little and that the money you lend to a government comes back to you cheaply.

That assumption is being renegotiated worldwide. Yields have risen across the United States, Germany and the United Kingdom, and euro zone yields have reached highs not seen in more than a decade. The direction is the same everywhere, which is what distinguishes a repricing from a local story.

Why the world’s largest single investor is rewriting its bond mandate

The most instructive development is not a yield at all. It is an allocation decision.

Norges Bank Investment Management, which runs Norway’s sovereign wealth fund at roughly US$2.3 trillion and is the largest single pool of investment capital in the world, has proposed cutting government bonds from 70% to 50% of its bond benchmark. US Treasuries, its biggest holding, would take the largest reduction, close to US$80 billion out of about US$215 billion held at the end of June. The corresponding increase would go into non-government US fixed income, including corporate bonds and mortgage-backed securities, lifting that allocation from 16.2% to 27.6%.

Two features of this matter more than the headline. First, it is a benchmark change rather than a trade. A benchmark is the neutral position an institution returns to, so changing it is a statement about the next decade rather than the next quarter. Second, the fund has said any shift would be phased in gradually to limit market impact, and the proposal still awaits a response from Norway’s finance ministry. This is not a fire sale. It is a large, patient investor concluding that it is not being paid enough to lend to governments.

The structural reasons underneath

Three forces are pushing in the same direction, and none of them resolve inside a quarter.

Public finances have deteriorated across the developed world, and the US debt load has passed US$40 trillion. More borrowing means more supply of government bonds, and more supply generally means investors demand a better price. Japan’s ministries are expected to request a record initial budget for the coming fiscal year, which is the same dynamic in a different currency.

Corporate issuance has surged alongside it. The buildout of AI infrastructure is being funded heavily through debt markets, and that competes directly with governments for the same pool of capital. The scale is not small. Announced multi-year commitments across the sector now run into the hundreds of billions.

Energy costs have added an inflation impulse that arrives from the supply side rather than from demand, which is the least convenient kind for a central bank to offset. Together these support a higher term premium, meaning investors are asking for more compensation to lend for longer. After two decades in which that premium was suppressed, its return changes the arithmetic of a portfolio.

What this changes for fixed income held in two currencies

Fixed income tends to be the least examined part of a cross-border portfolio. It rarely produces a dramatic statement line, so it gets reviewed last, and cross-border households frequently hold it twice, once in a Canadian account and once in a US account, without anyone ever comparing the two sleeves side by side.

Three questions are worth putting to that combined position. What is this money actually for? If the answer is stability and it is invested at long duration, a rising term premium means the holding is more sensitive to rate movement than the label suggests. If the answer is income, the current environment is more generous than it has been in years, which is the constructive half of this story.

What currency is it in, and does that match the currency it will be spent in? A bond sleeve held in the wrong currency introduces exchange rate risk into the part of the portfolio that was chosen for safety, which is close to the opposite of the intention.

And how is it taxed on each side? Interest income is treated differently in Canada and the United States, and the account it sits in can change the after-tax result more than the yield does. That comparison is only possible when both sleeves are looked at together.

None of this argues for abandoning bonds. Higher yields are a better deal for a buyer than lower ones. It argues for knowing what the holding is doing, rather than assuming it is the boring part.

Frequently asked questions

What is a term premium?

The extra return investors demand for lending money over a longer period rather than a shorter one, to compensate for the uncertainty involved. For roughly two decades this premium was unusually compressed, partly through central bank bond buying. Its return means long-dated bonds now pay more, and also move more.

Why does Japan’s bond yield matter to a Canadian investor?

Because capital moves across borders looking for the best risk-adjusted return. When yields rise in one large market, investors there have less reason to reach into others, and pricing adjusts globally. Japan’s 10-year reaching 3% for the first time since 1996 is significant as a marker of how broad the repricing is, not because most investors hold the bond.

Is Norway actually selling US Treasuries?

Not yet, and not abruptly. Norges Bank Investment Management has proposed reducing government bonds from 70% to 50% of its bond benchmark, which would cut roughly US$80 billion from Treasury holdings. The proposal was made in response to questions from Norway’s finance ministry, awaits a decision, and the fund has said any change would be implemented gradually.

Are government bonds still a safe holding?

They remain among the lowest credit-risk assets available, in the sense that repayment is highly likely. What has changed is price volatility. Rising yields mean existing bonds fall in value, and longer-dated bonds fall further. Safety from default and stability of market value are two different things, and the last few years have made that distinction expensive to ignore.

I hold bonds in both my Canadian and US accounts. Is that diversification?

Not necessarily. If both sleeves hold similar duration and similar issuer types, you may hold the same exposure twice in two currencies rather than two different exposures. Genuine diversification within fixed income comes from differences in duration, credit quality and issuer type, not from the country the account happens to sit in.

Does a rising term premium mean I should avoid long-dated bonds?

It means long-dated bonds carry more price sensitivity, and that the compensation for holding them has improved. Whether that trade is appropriate depends on when the money is needed and how much fluctuation the plan can tolerate before it changes behaviour. This is a question about matching holdings to obligations, not a directional call.
