Higher Interest Rates Not Just for Longer, but Maybe Forever

On Wednesday, Federal Reserve officials surprised markets by signalling interest rates won’t fall as much as previously planned.

The tweak might be more important than it looks. In their projections and commentary, some officials hint that rates might be higher not just for longer, but forever. In more technical terms, the so-called neutral rate, which keeps inflation and unemployment stable over time, has risen.

This matters to any investor, business or household whose plans depend on interest rates over a decade or longer. It could explain why long-term Treasury yields have risen sharply in the past few months, and why stocks are struggling.

The neutral rate isn’t literally forever, but that captures the general idea. In the long run neutral is a function of very slow moving forces: demographics, the global demand for capital, the level of government debt and investors’ assessments of inflation and growth risks.

The neutral rate can’t be observed, only inferred by how the economy responds to particular levels of interest rates. If current rates aren’t slowing demand or inflation, then neutral must be higher and monetary policy isn’t tight.

Indeed, on Wednesday, Fed Chair Jerome Powell allowed that one reason the economy and labor market remain resilient despite rates between 5.25% and 5.5% is that neutral has risen, though he added: “We don’t know that.”

Before the 2007-09 recession and financial crisis, economists thought the neutral rate was around 4% to 4.5%. After subtracting 2% inflation, the real neutral rate was 2% to 2.5%. In the subsequent decade, the Fed kept interest rates near zero, yet growth remained sluggish and inflation below 2%. Estimates of neutral began to drop. Fed officials’ median estimate of the longer-run fed-funds rate—their proxy for neutral—fell from 4% in 2013 to 2.5% in 2019, or 0.5% in real terms.

As of Wednesday, the median estimate was still 2.5%. But five of 18 Fed officials put it at 3% or higher, compared with just three officials in June and two last December.

In 2026, officials project the economy growing at its long-term rate of 1.8%, unemployment at its long-run natural level of 4%, and inflation at its 2% target. Those conditions would normally be consistent with interest rates at neutral. As it happens, officials think the fed-funds rate will end the year at 2.9%—another hint they think neutral has risen.

There are plenty of reasons for a higher neutral. After the global financial crisis, businesses, households and banks were paying down debt instead of borrowing, reducing demand for savings while holding down growth and inflation. As the crisis faded, so did the downward pressure on interest rates.

Another is government red ink: Federal debt held by the public now stands at 95% of gross domestic product, up from 80% at the start of 2020, and federal deficits are now 6% of GDP and projected to keep rising, from under 5% before the pandemic. To get investors to hold so much more debt probably requires paying them more. The Fed bought bonds after the financial crisis and again during the pandemic to push down long-term interest rates. It is now shedding those bond holdings.

Inflation should not, by itself, affect the real neutral rate. However, before the pandemic the Fed’s principal concern was that inflation would persist below 2%, a situation that makes it difficult to stimulate spending and can lead to deflation, and that is why it kept rates near zero from 2008 to 2015. In the future it will worry more that inflation persists above 2%, and err on the side of higher rates with little appetite for returning to zero.

Other factors are still pressing down on neutral, such as an aging world population, which reduces demand for homes and capital goods to equip workers.

So neutral has probably risen since 2019, but not to its pre-2008 level. Indeed, futures markets peg rates a decade from now at around 3.75%.

Of course, this is all just a forecast. If inflation comes down painlessly in the next year, if growth slows abruptly, or if Treasury yields drop, then estimates of neutral will also come down. For now, the evidence suggests the public should get used to higher rates as far as the eye can see.

Apple has dominated the electronics supply chain for years. No more.

Artificial-intelligence companies are writing huge checks for chips, memory, specialised glass fibre and more, and they have begun to out-duel Apple in the race to secure components.

Suppliers accustomed to catering to Apple’s every whim are gaining the leverage to demand that the iPhone maker pay more.

Apple’s normally generous profit margins will face pressure this year, analysts say, and consumers could eventually feel the hit.

Chief Executive Tim Cook mentioned the problem in a Thursday earnings call, saying Apple was seeing constraints in its chip supplies and that memory prices were increasing significantly.

Those comments appeared to weigh on Apple shares, which traded flat despite blowout iPhone sales and record company profit.

“Apple is getting squeezed for sure,” said Sravan Kundojjala, who analyses the industry for research firm SemiAnalysis.

AI chip leader Nvidia recently became the largest customer of Taiwan Semiconductor Manufacturing , or TSMC, Nvidia Chief Executive Jensen Huang said on a podcast.

Apple had been TSMC’s biggest customer by a wide margin for years. TSMC is the world’s leading manufacturer of advanced chips for AI servers, smartphones and other computing devices.

Spokesmen for Apple and TSMC declined to comment.

The big computers that handle AI tasks don’t look like the smartphones consumers own, but many companies supply components for both. In particular, memory chips are in short supply as companies such as OpenAI, Alphabet’s Google, Meta , Microsoft and others collectively spend hundreds of billions of dollars to build AI computing capacity.

“The rate of increase in the price of memory is unprecedented,” said Mike Howard , an analyst for research firm TechInsights.

That applies both to the flash memory chips that store photos and videos, called NAND, as well as the memory used to run apps quickly, called DRAM.

By the end of this year, the price of DRAM will quadruple from 2023 levels, and NAND will more than triple, estimates TechInsights.

Howard estimates that Apple could pay $57 more for the two types of memory that go into the base-model iPhone 18 due this fall compared with the base model iPhone 17 currently on sale. For a device that retails for $799, that would be a big hit to profit margins.

Apple’s purchasing power and expertise in designing advanced electronics long made it an unrivaled Goliath among the Asian companies that make most of the iPhone’s parts and assemble the device.

Apple spends billions of dollars a year on NAND, for instance, according to people familiar with the figures, likely making it the single biggest buyer globally. Suppliers flocked to win Apple’s business, hoping to leverage its know-how and prestige to attract other customers.

These days, however, “the companies now pushing the boundaries of human‑scale engineering are the ones like Nvidia,” said Ming-chi Kuo, an analyst with TF International Securities.

Demand for AI hardware is poised to keep growing rapidly. Apple’s spending growth is modest in comparison with what is being spent to fill up AI data centers, even though it is breaking records with huge sales of the iPhone 17.

Samsung Electronics and SK Hynix are raising the price of a type of DRAM chip for Apple, according to people familiar with Apple’s supply chain.

Big AI companies pay generously and are willing to lock in supply and make upfront payments, giving the South Korean chip makers leverage against the iPhone maker.

Apple signs long-term contracts for memory, but it has used its heft to squeeze suppliers.

Its contracts have empowered it to negotiate prices as often as weekly, and to even refuse to buy any memory from a supplier if Apple didn’t view the price as favorable, according to people familiar with its memory purchases.

To boost leverage with suppliers, Apple even began stocking more inventory of memory. That was atypical for Cook, who normally cuts inventory to the bone to maximize Apple’s cash flow.

Apple is fighting not only for current deliveries but also for the attention of engineers at suppliers.

Glass scientists who worked on developing the smoothest and lightest smartphone displays are now also spending time on specialised glass for packaging advanced AI processing chips, according to industry executives.

Makers of sensors and other gizmos inside the iPhone are winning new business from AI companies such as OpenAI that are developing their own hardware.

Still, suppliers said they were far from giving up on business with Apple. Working with Apple is a form of education, they said, because it remains one of the most demanding and disciplined customers in the industry.

TSMC, the Taiwanese chip manufacturer, has built successive generations of its most advanced chips with Apple as its lead customer, relying on the big predictable demand for iPhones.

Now that TSMC is doing more business with Nvidia and other AI companies, people with knowledge of the chip supply chain said Apple was exploring whether some lower-end processors could be made by someone other than TSMC.

One of Apple’s biggest profit-spinners is selling extra memory for far more than the memory chips cost the company.

Last fall Apple discontinued the iPhone Pro model with 128 gigabytes of storage.

Customers who want that model must now start at 256 gigabytes and pay $100 more—the type of move that could be repeated this year to help Apple offset higher costs, wrote Craig Moffett, an analyst at Moffett Nathanson, in an investor note.

However, Apple isn’t expected to raise the price of its next iPhone models over similarly equipped iPhone 17s, said Kuo, the analyst.

News Corp, owner of The Wall Street Journal, has a commercial agreement to supply news through Apple services.
