Daily Basis — March 18, 2026

The Federal Reserve held rates steady today, which is the kind of non-event that manages to be the most important thing that happened. Markets sold off, oil is at levels that make your gas station receipt feel like a medical bill, and somewhere in the background Micron is about to tell us whether the AI trade is still working. It was one of those days where everything is connected to everything else, and none of the connections are particularly comforting.

The Fed Waits

The basic idea behind central banking is that you have one tool (interest rates) and you use it to manage, roughly, two things (inflation and employment). When both of those things are behaving nicely, your job is easy. When they are pulling in opposite directions, or when some third thing you have no control over (say, a war) starts messing with both of them simultaneously, your job becomes very hard. Today was a hard day to be a central banker.

The Federal Open Market Committee voted 11-1 to hold the federal funds rate at 3.5% to 3.75%, which is where it has been sitting for a while now. The one dissent is interesting mostly as a signal that unanimity is fraying, though we don't yet know which direction the dissenter wanted to go. In a room full of economists staring at the same data, the fact that someone felt strongly enough to break ranks tells you the data is genuinely ambiguous.

And the data really is ambiguous, or rather, it is unambiguous in an unhelpful way. The Producer Price Index came in at +0.7% for the month, which is hot. Not "the economy is on fire" hot, but "hmm, that's more than we wanted" hot. PPI measures what producers pay for inputs, and it tends to flow downstream into the prices you and I pay for things eventually. When producers are paying more for energy and materials, they generally do not eat those costs out of the goodness of their hearts.

The complicating factor, obviously, is oil. Brent crude at $108 a barrel is not a number the Fed can do anything about. Jerome Powell cannot call up the Middle East and ask them to please stop having a war because it is interfering with his inflation targets. This is the fundamental awkwardness of supply-side inflation: raising interest rates doesn't produce more oil. It just makes it more expensive for everyone else to borrow money while they're also paying more for gas. The Fed knows this, which is partly why they held.

Powell's press conference will be the main event, as it usually is. The prepared statement is drafted by committee and reads like it. The press conference is where Powell has to answer questions like "so when are you cutting rates?" and try to say nothing while appearing to say something. The market's current expectation for the first cut has been pushed out again, which means if you have an adjustable-rate mortgage or are hoping to refinance, the timeline just got a little longer. For people with savings accounts, I suppose this is the silver lining, though 3.5% on your savings feels less exciting when gas is $4.50 a gallon.

The phrase "data dependent" will appear in the statement, because it always does. What it means in practice right now is: we have no idea what oil prices are going to do, and until we do, we're not moving.

PPI and the Selloff

Markets had a brief, optimistic morning. Then the PPI number came out and everyone remembered that inflation is still a thing. The Dow fell 0.5%, the S&P 500 dropped 0.3%, and the Nasdaq declined 0.4%, which in the grand scheme of things is not a catastrophe but is the kind of broad-based decline that suggests genuine nervousness rather than sector rotation.

The mechanics here are straightforward. Hotter inflation means the Fed is less likely to cut rates soon. Higher rates for longer means the present value of future corporate earnings goes down (because you discount them at a higher rate). It also means bonds become relatively more attractive compared to stocks, so some money flows out of equities. This is Finance 101 stuff, but it plays out in real time in a way that affects your 401(k) balance, which probably ticked down a fraction of a percent today.

What's more interesting is the timing. Getting a hot inflation print on the same day as a Fed meeting creates a kind of interpretive pileup. Investors are trying to process the PPI data and simultaneously guess how the Fed will react to it, knowing that the Fed had the data before they made their decision. It's like trying to read someone's poker face while also looking at your own cards.

The Summary of Economic Projections, which comes out alongside the rate decision, is what traders will actually be parsing tonight. This is the "dot plot," where each Fed governor puts a dot on a chart showing where they think rates will be at various points in the future. The dots have a mixed track record as predictive tools (the Fed is not notably better at predicting the future than anyone else), but they matter because they signal intent. If the median dot for year-end 2026 moves up, that's the Fed telling you they expect to cut less than they previously thought. Given today's PPI, that seems likely.

For the median person with a retirement account, days like this are not fun but are also not meaningful in isolation. The market is down a third of a percent. If you zoom out to a one-year chart, today will be invisible. The thing to watch is whether this becomes a trend, whether sticky inflation and geopolitical risk keep pushing rate-cut expectations further into the future, because that affects everything from mortgage rates to credit card interest to how aggressively companies hire.

Oil at $108

There is a version of the oil story that is purely about supply and demand curves, and then there is the version that involves missiles hitting energy infrastructure in Iran. We are living in the second version.

Brent crude at $108 per barrel and WTI near $98 represents a significant move. For context, Brent was in the $70s for much of late 2024 and early 2025. A roughly 40% increase in crude prices over that span is the kind of thing that shows up everywhere: at the gas pump, in airline ticket prices, in the cost of shipping goods, in your grocery bill (because it turns out that transporting food requires fuel, which is one of those obvious facts that only becomes salient when fuel gets expensive).

The Iran situation is genuinely concerning from an energy-markets perspective because of geography. Iran sits next to the Strait of Hormuz, through which something like 20% of the world's oil supply passes on tankers. The fact that Iran is still managing to move its own oil through the strait is a small comfort, but "for now" is doing a lot of work in that sentence. Any serious disruption to Hormuz traffic would make $108 Brent look like a bargain, which is a sentence I do not enjoy writing.

For energy stocks, this is obviously great. If you own Exxon or Chevron or an energy ETF, your portfolio is having a different day than everyone else's. This is one of those situations where the thing that's bad for the economy in general is good for a specific sector, which is why financial advisors talk about diversification. Your energy holdings are hedging your everything-else holdings.

For the Fed, expensive oil is the worst kind of problem. It's inflationary, but it's not the kind of inflation that responds to interest rate changes. You can't drill for oil by raising the federal funds rate. You can cool demand for oil by making the economy weaker, but "let's make the economy worse so people drive less" is not a great pitch. This is why Powell's press conference will involve a lot of careful language about distinguishing between "core" inflation (excluding food and energy) and headline inflation (including them). The Fed officially targets headline inflation but tends to look through energy spikes when making policy, on the theory that they're temporary. Whether a war-driven spike is temporary depends entirely on how the war goes, which is not something economists are trained to predict.

The connection to your personal finances is pretty direct. If you drive to work, you're spending more on gas. If you're shopping for a car, the economics of an EV just got slightly more favorable (though EVs have their own cost issues). If you're invested in a broad index fund, you're probably slightly down today but your energy allocation is helping cushion it. And if you were hoping for lower interest rates to refinance your mortgage, the oil spike is one more reason that's getting delayed.

Micron's Moment

Micron Technology reports earnings after the close today, and the stock is up 60% year-to-date, which is the kind of number that makes you either very excited or very nervous depending on whether you think the rally is justified.

The bull case for Micron is essentially the bull case for AI. Micron makes memory chips (DRAM and NAND flash), and it turns out that training and running large AI models requires enormous amounts of memory. Every data center that Nvidia sells GPUs into also needs Micron's memory to go alongside those GPUs. It's the less glamorous but entirely necessary part of the AI infrastructure stack, like being the company that makes the electrical wiring for a fancy new building. Nobody writes breathless headlines about wiring, but you can't have the building without it.

The question going into earnings is whether Micron can deliver numbers that justify a 60% move. The stock is trading at a valuation that implies significant growth ahead, and the market is not patient with expensive stocks that disappoint. If Micron's guidance is strong, it validates the broader semiconductor and AI trade. If it's soft, or even just in-line-but-not-spectacular, you might see a pullback not just in Micron but in the whole AI complex, because the narrative depends on demand continuing to accelerate.

There's an interesting China angle here too. Several Chinese companies have been getting approvals for US revenue streams, which matters for semiconductor companies because China is both a huge market and a geopolitical complication. The semiconductor industry lives in this weird space where the US and China are simultaneously each other's biggest customers and biggest strategic rivals. Micron itself was banned from some Chinese government purchases a few years ago, so any thawing in the US-China tech relationship is relevant.

General Mills and Macy's also report today, which in normal times would be the more relatable earnings (cereal and department stores versus memory chips). But we live in the AI economy now, apparently, so the company that makes DRAM modules gets more attention than the company that makes Cheerios. Whether this ordering of priorities makes sense is a question I'll leave to future economic historians.

For your portfolio, Micron's earnings are a useful data point regardless of whether you own the stock directly. If you have any exposure to a broad index or a tech-heavy fund, the AI trade is a meaningful part of your returns this year. Understanding whether the fundamentals support the stock prices, or whether we're in the "vibes" phase of a hype cycle, matters for how you think about your allocation going forward.

Alibaba Restructures

Alibaba's American depositary receipts rose 3.6% today on news that the company is consolidating its AI operations under a single unit, which is the kind of corporate reorganization that sounds boring but actually signals something significant.

The logic is pretty simple. Alibaba had AI efforts scattered across multiple divisions, which is how things tend to work at large conglomerates. Somebody in cloud computing is doing AI, somebody in e-commerce is doing AI, somebody in logistics is doing AI, and they're all building slightly different versions of the same infrastructure while fighting over budget in separate meetings. Putting it all under one roof is the "we're serious about this now" move. It also makes it easier to measure whether AI is actually making money, which is a question that many companies are finding uncomfortable to answer honestly.

The price hikes on select services are the other half of the story, and arguably the more interesting half. Alibaba is signaling that it believes its AI-enhanced products are valuable enough to charge more for. This is a real test. It is easy to add AI features to things; every company is doing that. It is harder to add AI features that customers will actually pay a premium for. If Alibaba can pull that off, it suggests the AI investment is translating into real revenue rather than just R&D expense.

The broader context is China's tech sector trying to find its footing in a world of US-China trade tensions. Beijing has been pushing its tech champions to be more profitable (this is a change from the era of growth-at-all-costs), and Alibaba's restructuring fits that directive. The approvals for Chinese companies to access US revenue streams, reported alongside this news, suggest some degree of pragmatic accommodation between the two countries, at least in the tech space. Both sides want their companies to make money, even if they disagree about everything else.

For American investors who own Chinese tech stocks (directly or through emerging-market funds), Alibaba's move is cautiously encouraging. The stock is still well below its all-time highs from 2020, so there's a lot of ground to make up. But a company that's restructuring for profitability and raising prices is a company that's at least trying to return value to shareholders, which has not always been the top priority for Chinese tech firms.

The Bottom Line

Today was one of those days where the connecting thread is uncertainty, and the market's response to uncertainty is to do a little bit of everything: sell stocks, buy oil, stare at the Fed, and wait for earnings. The PPI print reminded everyone that inflation is not a solved problem, the Iran situation reminded everyone that geopolitics can override economics, and the Fed's hold reminded everyone that the people in charge of monetary policy are just as uncertain as the rest of us. Micron's earnings tonight will either reinforce the AI narrative or give people one more thing to worry about. If you have a long time horizon (and at 25 to 40, you do), the correct response to days like this is probably to do nothing, which is, not coincidentally, exactly what the Fed decided to do.
