The True Cost of Power: Brent Crossed $100 and Rates Hit a Three-Year High. Which Pressure Should an Owner Act On?
Brent crude crossed $100 a barrel this week, and the 10-year Treasury yield climbed to its highest level since 2023. For most of the year these two prices moved on separate clocks. This week they began moving together, driven by the same conflict, and the convergence changes how an owner should read the pressure on a building's value.

A Note From the Editor
In recent weeks this column treated rates, oil, and power as three separate weather systems, each on its own clock. This week two of them merged. The Hormuz conflict is now lifting oil and, through the inflation fear it feeds, pushing interest rates in the same direction at the same time. One root, two pressures, amplifying each other. That makes the third pressure, the structural cost of power, both harder to ignore and more clearly the one an owner can actually act on.
Act on the cost of power, the one pressure that is structural and within an owner's control. Brent crude crossed $100 a barrel this week for the first time since the spring, and the 10-year Treasury yield reached about 4.8 percent, its highest since 2023. Those two moves used to run independently. Now they share one root: the conflict around the Strait of Hormuz lifts oil, oil feeds inflation fear, inflation fear pushes the Federal Reserve toward higher rates, and higher rates raise the cost of every real estate deal. An owner cannot end a war or set the Fed's rate. An owner can decide how much of a building's power comes from a grid whose cost keeps climbing, and that decision pays off regardless of what oil and rates do next.
Key Facts at a Glance
Brent crude traded near $102 a barrel on September 9, crossing $100 for the first time in months and running roughly 40 percent above pre-conflict levels.
The 10-year Treasury yield reached about 4.8 percent this week, its highest since 2023, and markets price close to even odds of a Federal Reserve rate increase on September 16.
The August inflation report lands Friday, September 11, and will likely decide the Fed's move; July headline inflation stood at 3.4 percent.
Oil and interest rates now share one geopolitical root, so they amplify each other rather than moving on separate clocks.
The structural constraint is equipment: about 2,061 gigawatts sit in interconnection queues with a five-year median wait, and large transformers carry lead times of 128 weeks or more.
Commercial electricity averaged 13.54 cents per kilowatt-hour in the latest federal data, up 4.7 percent in a year, a cost that does not reverse when a conflict ends.
Why Did Brent Cross $100 This Week?
Oil crossed $100 for a geopolitical reason, not an economic one. Brent crude traded near $102 a barrel on the morning of September 9, up more than $2 from the prior day and roughly $35 higher than a year earlier, according to price data compiled by Fortune. The move caps a week in which crude rose nearly 10 percent as fighting around the Strait of Hormuz intensified.
The escalation is concrete. The United States struck three Iranian oil tankers over the weekend after Iran fired ballistic missiles at two Navy warships, and Saudi Aramco's Jazan facilities, which process about 400,000 barrels a day, were hit again on Monday, as tracked in market reporting. Iran has said an arrangement with Oman could create a restricted corridor through the strait that would require vessels to coordinate with Tehran. Roughly 7 million barrels a day still move through the waterway, so the price reflects fear of disruption more than an actual halt in supply.
That distinction matters because it tells an owner what kind of pressure this is. The U.S. Energy Information Administration (EIA) still forecasts that Brent will ease back toward the mid $80s and average near $69 in 2027 as disruptions fade and inventories rebuild, per its Short-Term Energy Outlook. A price that a federal agency expects to fall by a third within 18 months is a cyclical spike, painful and real, but temporary in nature. It is not a permanent change in the cost structure of a building.
Why Are Oil and Interest Rates Moving Together Now?
They move together because they now share one cause. The 10-year Treasury yield, the benchmark that sets the pace for commercial mortgages, reached a high of about 4.81 percent this week before settling near 4.79 percent, its highest level since 2023, according to market reporting. The immediate driver is the oil spike itself. When crude jumps, investors expect faster inflation, and they demand higher yields to hold government debt, which lifts the rates that price real estate.
The chain runs through the Federal Reserve. After a stronger-than-expected August jobs report showed 162,000 positions added against forecasts near 56,000, markets moved to price close to even odds of a quarter-point rate increase at the September 16 meeting, a striking shift toward tightening rather than easing, as reported in bond-market coverage. Fed leadership is divided, with a more hawkish chair signaling a commitment to tame inflation and at least one governor arguing for holding rates steady if inflation continues to cool. The August consumer price index, due Friday, September 11, is the data point most likely to settle the question.
A second inflation input landed the same week. Canada's retaliatory tariffs on more than 700 US products, ranging from 15 to 50 percent, took effect September 8, matching a US move that had doubled duties on steel and aluminum to 50 percent, as reported by CNN. That adds a fresh, non-oil push on the same price data the Fed will weigh on Friday, and it raises the cost of the steel and aluminum that go into construction and electrical equipment. The trade dispute is context around this week's decision rather than the driver of it, but it pushes in the same direction as the oil spike.
For an owner, the mechanism is what matters. A cap rate, the yield a buyer requires on a property's income, tends to move with Treasury yields. When the 10-year rises, cap rates drift up with it, and a higher cap rate lowers the value of the same income stream. So a single geopolitical event now presses on a building twice: once through the oil price that raises operating and construction costs, and again through the interest rate that raises the cost of capital and compresses value. Last month these were separate risks to track. This week they are one risk with two faces.
What Does the Convergence Do to a Building's Value?
The convergence raises the value of every dollar of durable operating savings. Property value rests on net operating income (NOI), the income a building keeps after operating expenses, divided by the cap rate. When cap rates rise, each dollar of NOI supports less value, so protecting and growing NOI becomes more important, not less. The arithmetic is fixed and worth keeping in view: every $1,000 of durable annual NOI improvement adds roughly $12,500 in asset value at an 8 percent cap rate. When required returns climb, an owner has to work harder to defend the same valuation, and a permanent reduction in a controllable cost is one of the few levers that does the work.
Energy is that lever more often than any other line on the statement. For many commercial buildings it is the largest controllable operating expense, and unlike taxes or debt service, it responds directly to onsite investment. A building that trims its power cost by a verifiable amount each year is not only cheaper to run; it is worth measurably more, and that added value grows more valuable precisely when capital is expensive and buyers are demanding higher returns. The pressure from rates and oil, in other words, sharpens the case for acting on the one cost an owner can actually move.
Why Is the Cost of Power the Structural Pressure?
The cost of power is structural because it does not reverse when the conflict ends or the Fed pivots. Commercial electricity averaged 13.54 cents per kilowatt-hour in the most recent federal data, up 4.7 percent from a year earlier, with regional rates far higher, above 24 cents in California and much of the Northeast, according to the EIA. That increase is not driven by a headline that could fade next month. It is driven by the physical limits of the grid: record demand from data centers, electrification, and manufacturing colliding with infrastructure that cannot expand fast enough.
The hard evidence of that limit is the equipment itself. About 2,061 gigawatts of generation and storage sit waiting in interconnection queues, the lines projects join to connect to the grid, and the median project that reached operation in 2025 took about five years from request to switch-on, up from 22 months in 2008, according to Lawrence Berkeley National Laboratory. The bottleneck extends to the hardware. Wood Mackenzie's Q2 2025 transformer market survey put lead times for large power transformers at 128 weeks and for generator step-up transformers at 144 weeks, with roughly 80 percent of large units imported. Equipment availability has replaced capital and permitting as the primary constraint on connecting new power.
The trade war adds one direct energy risk in specific markets. Ontario, which supplies electricity to New York, Michigan, and Minnesota, has signaled it could tariff or cut off power exports to the United States if the dispute worsens, a step the province briefly took in an earlier 2025 round before reversing it, according to Utility Dive. For an owner in those states, that is a concrete near-term reason to value onsite generation and reduced grid dependence, on top of the structural cost pressure already in place.
Set the three pressures side by side and the difference is clear. Oil may retreat toward the mid $80s within the year. Rates may ease when inflation cools or the Fed changes course. Neither outcome is within an owner's control, and both may arrive on their own. The cost of power is the pressure that stays, because the demand behind it keeps growing and the grid behind it keeps lagging. It is also, conveniently, the one an owner can address directly.
How Should an Owner Hedge Right Now?
The week's noise resolves into a short set of actions, each matched to the pressure it addresses.
1. Act on the cost you control. Onsite solar, battery storage, and demand management cut the power bill directly, and the savings begin immediately and can be verified against existing utility bills. That is the hedge against the one pressure that will not reverse on its own.
2. Favor projects with fast, verifiable payback. When capital is expensive, the strongest case belongs to measures whose savings start at once and show up on the meter, rather than long-dated bets that depend on a distant return.
3. Use third-party ownership where it fits. A power purchase agreement (PPA), a contract in which a developer owns the system and sells the power at a set rate, or a roof lease to a solar developer, lets an owner capture lower and steadier energy costs without spending capital that is now competing with expensive debt paydown.
4. Read the lease before the rate rises further. Confirm whether energy costs pass through to tenants and whether expense stops, the cap on the landlord's share of operating costs, leave the owner exposed to rising power prices. The answer decides who actually absorbs the structural increase.
5. For planners, treat the grid constraint as the durable one. The interconnection reforms and distributed-energy rules that ease local capacity will matter long after this week's oil and rate moves are forgotten, because the demand straining the grid is structural.
What About the Technology Coming to Market?
One technology shift is worth an owner's attention, because it makes onsite power more efficient over time. The artificial intelligence (AI) buildout is standardizing on native direct-current power inside data centers, an 800-volt direct current design whose open specification was published in July 2026 ahead of one-megawatt server racks arriving in 2027, and that shift is pulling the whole power architecture toward direct current, as described by NVIDIA and its Open Compute Project partners. The reason it matters to a commercial owner is indirect but real. Solar panels and batteries are native direct-current devices, so as the market moves toward direct current, a solid-state transformer, a software-controlled device that converts and routes power while blending grid, solar, and battery and replacing a stack of legacy electrical gear, becomes a more efficient way to run a building's own generation. The practical move is to design electrical rooms to be ready for that hardware now and deploy it as it matures between 2026 and 2030, since it can sidestep both the interconnection queue and the transformer lead times described above. DG Matrix, whose Interport unit this publication examined earlier this year, is an early barometer of the category, and the field is broadening as Eaton, Hitachi Energy, Schneider Electric, ABB, Siemens, and Vertiv build to the same open standard.
The Bottom Line
Two pressures converged this week, and one did not. Oil crossed $100 and rates hit a three-year high because a single conflict is now driving both, and the August inflation report on Friday may push them further in the same direction or begin to unwind them. Either way, both remain outside an owner's control and may reverse when their triggers do. The cost of power will not reverse, because the demand behind it keeps growing and the grid behind it keeps lagging. An owner cannot reopen the Strait of Hormuz or set the Federal Reserve's rate, but an owner can decide how much of a building's power comes from a grid that will only get more expensive. In a week when the pressures an owner cannot control are amplifying each other, the pressure an owner can control is the one worth acting on.

Frequently Asked Questions
Why did oil cross $100 this week?
For a geopolitical reason. Fighting around the Strait of Hormuz escalated, with the United States striking Iranian tankers and Saudi facilities hit again, pushing Brent near $102 a barrel, roughly 40 percent above pre-conflict levels. About 7 million barrels a day still flow through the strait, so the price reflects fear of disruption more than an actual supply halt.
Are oil and interest rates connected now?
This week, yes. The oil spike feeds expectations of faster inflation, which pushes the Federal Reserve toward higher rates and lifts the 10-year Treasury yield. One geopolitical root is now driving both pressures at the same time, so they amplify each other rather than moving independently.
Does the oil price hit my electricity bill?
Only indirectly. Almost no US electricity is made from oil, so the rise reaches a building through diesel, construction materials, and general inflation rather than the meter. The larger and more durable driver of power cost is structural grid demand, which is what an owner should focus on.
Why act on energy cost rather than wait for oil and rates to settle?
Because energy cost is the structural pressure that will not reverse when the conflict ends or the Fed pivots, and it is the one an owner can address directly. Onsite generation and efficiency cut the bill immediately, and the savings hold regardless of what oil and rates do next.
Does the US-Canada trade war affect a building's energy cost?
Indirectly for most owners, and directly for some. New tariffs that took effect September 8 add to inflation and raise the cost of steel, aluminum, and electrical equipment. The sharper risk is regional: Ontario supplies power to New York, Michigan, and Minnesota and has signaled it could tariff or halt those exports if the dispute worsens, which gives owners in those states a concrete reason to value onsite generation.
Should I invest in an energy project when borrowing is so expensive?
Favor fast-payback projects whose savings begin at once, and consider third-party ownership such as a power purchase agreement so the project does not compete with expensive debt. A measure that lowers and steadies operating cost improves net operating income, which matters more, not less, when capital is costly.
