Global bond markets cannot seem to catch their breath. On Sept 10, the 30-year US Treasury (UST) yield rose to 5.37%, a level not seen in more than two decades, while the two-year jumped 13 basis points (bps) within a day, a steep movement that is atypical of short-term securities. At the same time, Japan’s 10-year government bond yield crossed 3% early this month, a level it had not seen since September 1996. Brent crude went through US$100 and on to US$105 after attacks on shipping in the Strait of Hormuz. The European Central Bank (ECB) raised rates in September for the second time this year, citing inflation risks. Closer to home, the 10-year Malaysian Government Securities (MGS) yield rose 29.5bps between Aug 26 and Sept 9, to 4.16%.

That is a lot for one fortnight. My first instinct, and I suspect yours, was to ask which of these was the real culprit. Was it the oil shock? The hike repricing? The fiscal worries? I spent a good while trying to rank them before realising that ranking was the wrong exercise.

Because it is all of them. The market is having its everything, everywhere, all-at-once moment — and that is not a joke about a film title. It is the analytically interesting part.

Here is what I mean. There are two clocks running in the bond market. The fast clock is the news cycle covering recent events on oil prices, war, inflation prints, shifting rate expectations, and it moves yields in days. The slow clock is more structural in nature, where the term premium — meaning the extra return an investor demands for lending long and living with whatever happens in between — is resetting towards its longer-run norm after years in which quantitative easing and yield curve control held it artificially low. That one moves over years.

Normally only one clock is audible at a time. We get a quiet structural drift punctuated by the occasional shock, and we can tell them apart. What makes this month unusual is that both are ticking loudly at once, and investors are being asked to price them simultaneously rather than in sequence. That is why every explanation feels partly right and wholly unsatisfying.

I have argued for some months that the slow clock is the one that matters. I still think so. But I will concede the obvious that on its own it no longer explains the pace or the violence of what we are seeing.

So let me take the fast clock seriously. Oil above US$100 feeds straight into inflation expectations, which is why the ECB moved and why markets have pulled forward expectations of further US Federal Reserve tightening. Heavier long-dated issuance has arrived in every major market at once and Japan has been selling its holdings of foreign securities, primarily UST, to fund record interventions defending the weakening yen and curb soaring imported inflation pressure. According to Japan’s finance ministry reserve data, its holding of foreign securities was down roughly US$87.8 billion against a record ¥15.4 trillion buying intervention.

But look closely at that last one because it is where the two clocks touch. Tactically it was a currency operation. Structurally it is consistent with the end of quantitative easing for Japan. The Bank of Japan has ended yield curve control and exited negative rates, closing out an era of near-zero long-end yields. The buyer that once absorbed super-long bonds regardless of yield to exogenously generate demand and push down yields is gone and the rest of the market players are now demanding compensation for holding them. As a result, yields have risen to reflect that.

Does any of this actually matter outside a trading floor? Yes, and it could lead to a vicious cycle if not managed well. Higher term premium raises the cost of servicing government debt. Higher debt service widens deficits. Wider deficits mean more issuance, which lifts term premium again. It turns slowly, but it turns in one direction and could become a pressure point for government fiscal health around the world, including Malaysia.

Which brings me home. Bank Negara Malaysia held the Overnight Policy Rate (OPR) at 2.75% on Sept 3, the fifth hold this year. Note, though, what changed in the wording. In July the stance was “appropriate and consistent” with the outlook but in September, “appropriate” was gone. To us, that keeps the door open to a gradual normalisation back to 3.00%, consistent with our existing view.

The curve heard it. Over that week post-OPR decision from Sept 2 to Sept 9, the three-month and one-year MGS moved barely (both +3.7bps), while the two-year rose 9.9bps, the three-year up 13.1bps and the five-year climbed 15.0bps. That is the market marking up the expected path of the policy rate. But look further out. The 10- and 30-year yields jumped 20.1bps and 17.7bps, respectively, more than the belly of the curve. That is a bear steepening, and it points to more than a domestic policy repricing. The extra move at the long end is the global demand for term premium showing up in our curve.

This development matters a lot domestically, especially when it comes to refinancing cost. For the Malaysian government specifically, we expect RM175 billion to RM185 billion of gross MGS and Government Investment Issue (GII) issuance this year, and every maturity is rolled at today’s yields, not 2020’s. Debt service charges have been rising amid a larger overall debt burden and higher interest rates. Debt servicing is projected to consume nearly 17% of government revenue in 2026 based on Budget 2026 projections, up from around 10% in the early 2010s and above the Ministry of Finance’s self-imposed 15% limit.

None of this is overtly alarming, at least for now. It is just that fiscal management simply gets harder the longer yields stay up. As with the point I made in “Go easy on government borrowing” last November (Issue 1601, Nov 17, 2025), with the currently still high debt stocks, even a modest rise in yields can balloon interest payment after refinancing. This makes fiscal consolidation all that much harder, barring new efforts to widen the tax base which itself comes with its own trade-offs.

So what should we watch? Demand at the long end. The 20-year MGS auction in late August drew a bid-to-cover of just 1.63 times, below the 2.0 times that generally signals healthy interest. Yet the 10-year GII auction in early September was covered a comfortable 2.29 times. Investors are not avoiding Malaysian government paper. They are avoiding duration. Whether that gap narrows through 2027 will tell us more than the headline 10-year yield does. It will provide a better guide to how much of the refinancing arithmetic we will actually have to absorb.
