What moves bitcoin (BTC/USD)?
Bitcoin (BTC/USD) is the largest cryptocurrency by market value, and for most of its life it traded on its own logic: a scarce digital asset whose price seemed to answer to nothing in stocks, bonds or the dollar. That has changed. Bitcoin now sits in exchange-traded funds, corporate treasuries and ordinary brokerage accounts, and the forces that move it overlap more and more with the forces that move every other market. What has not changed is the layer underneath: a supply schedule fixed in code, and a market structure that can turn a modest move into a large one within minutes.

Tendencies, not laws — bitcoin's correlation with risk sentiment shifts over time.
The halving: supply on a fixed schedule
No central bank or board sets bitcoin's supply. New coins enter circulation as the reward paid to the miners who confirm transactions and secure the network, and that reward is cut in half every 210,000 blocks, which works out to roughly every four years. The April 2024 halving took the reward from 6.25 to 3.125 bitcoin per block; the one before it, in May 2020, took it from 12.5 to 6.25. The next is due around April 2028. Total supply is capped at 21 million coins, and the halvings are how the network approaches that cap without ever quite reaching it.
The halving matters because it slows the flow of new supply while saying nothing about demand. If demand holds and new supply is cut in half, the arithmetic points toward a tighter market. Two things complicate that clean story. First, the date is known years in advance, so it is at least partly priced in long before it arrives; nothing about the day itself is a surprise. Second, each halving removes less new supply, relative to the coins already in circulation, than the one before it, so its direct effect shrinks with every cycle.
The historical pattern is real but thin. In each of the first three cycles, bitcoin's price peak came twelve to eighteen months after the halving, and the October 2025 high landed in the same window after the 2024 halving. Four cycles is a pattern, not a law. Each unfolded against a different macro and adoption backdrop, and each was more widely anticipated than the last, which is the usual way a well-known pattern loses its force.
Spot-ETF flows: demand you can watch every day
Until January 2024, a US investor's routes to bitcoin were awkward: an account at a crypto exchange, with the custody and security questions that came with it; a publicly traded trust that could sit at a steep premium or discount to the coins it held; or a futures-based fund that paid a roll cost. That month, US regulators approved eleven spot bitcoin ETFs, among them BlackRock's iShares Bitcoin Trust and Fidelity's Wise Origin Bitcoin Fund. A pension fund, an adviser or a retail investor could now buy bitcoin exposure the way they buy any other ETF.
Flows into and out of those funds have become one of the most watched gauges of bitcoin demand, and the reason is mechanical. A spot ETF holds bitcoin in proportion to the shares it has issued. A day of net inflows means the fund's custodian is buying coins in the open market; a day of net outflows means coins are being sold to meet redemptions. The figures are reported daily, and weeks of sustained inflows have tended to coincide with firmer prices, sustained outflows with softer ones. Treat that as a tendency rather than a rule. Flows respond to the same shifts in sentiment that move the price, so on any single day it is hard to say which is cause and which is effect.
Leverage and liquidations: why one move can run
Bitcoin also trades through a large derivatives market, above all through perpetual futures: contracts with no expiry that let a trader hold a leveraged long or short indefinitely. The leverage on offer runs far higher than in most traditional markets. When price moves against a crowded side, the most stretched positions are closed automatically, and those forced closures are themselves buying or selling that pushes price further, which liquidates the next layer of positions. An ordinary move can become a cascade within minutes.
October 2025 showed how far this can go. A US tariff announcement landed on a Friday evening, after stock markets had closed, with leveraged crypto positioning near record highs. Bitcoin lost more than a tenth of its value within hours, and roughly $19 billion of leveraged positions were force-closed inside a day, the largest such cascade on record at the time. Nothing in the underlying news was specific to bitcoin. The size of the move came from the market's structure, not from the headline.
Two features of that structure are worth keeping in mind. Bitcoin trades every hour of the week, so a headline that arrives on a Sunday night or a Friday evening meets thin order books and a full stack of leveraged positions. And open interest is a useful gauge of vulnerability: when a lot of leverage is stacked on one side, the same news can produce a far larger move than it would in a quieter market. This is a large part of why bitcoin's day-to-day volatility has run well above that of the major currency pairs, or of gold.
Why bitcoin now reacts to the Fed, CPI and payrolls
In its first decade, bitcoin barely noticed US economic data. It moved on its own news: exchange hacks, enforcement actions, disputes within its own community. As institutions and ETFs brought it into the same portfolios as stocks and bonds, that changed. Bitcoin now regularly moves around the same releases that move other risk assets: Federal Reserve rate decisions and the guidance that comes with them, the monthly CPI inflation report, and the non-farm payrolls report.
The link runs through liquidity and risk appetite rather than through anything bitcoin itself pays or earns. Looser expected Fed policy, whether lower rates or a hint that cuts are coming sooner, tends to support risk assets broadly, by making borrowing cheaper and pushing investors further out along the risk spectrum. As one of the most volatile assets available in a mainstream account, bitcoin has often been a beneficiary. Tighter expected policy works the other way. A hot CPI print that raises the odds of a more hawkish Fed, or a strong jobs report that pushes rate cuts further out, has repeatedly coincided with pressure on bitcoin alongside equities, though neither release says a word about crypto. How that rate repricing spreads through markets more broadly is the subject of what moves the US dollar.
A risk-on correlation that comes and goes
Bitcoin's relationship with equities, and with technology stocks in particular, is real but unstable. During the 2022 rate-hiking cycle it traded like a leveraged technology stock, falling with the Nasdaq as financial conditions tightened. In other stretches the link has loosened, and bitcoin has moved on a regulatory ruling, an exchange failure or an ETF headline with little regard for what stocks were doing that day.
Two framings compete. One treats bitcoin as a high-beta risk asset that amplifies whatever is moving equities; it has fit best when liquidity was tightening and leverage was high. The other treats it as a scarce, non-sovereign store of value with a family resemblance to gold, insulated from any one country's monetary policy; it belongs to bitcoin's early years and returns during episodes of currency or banking stress. Neither has held across bitcoin's history, and assuming either one is permanent is a reliable way to be surprised. A more useful habit is to check, on the day, whether bitcoin is tracking equities and the dollar or diverging from them. The answer tells you which driver is in charge.
Regulation and adoption: the catalyst with no calendar
Bitcoin is also exposed to a kind of news that has no equivalent in currencies or commodities. A regulator's ruling on a fund, an enforcement action against an exchange, a decision on how digital assets are classified or taxed: any of these can move price on its own, whatever rates or equities are doing. So can adoption news, such as a payments company or asset manager adding bitcoin custody, a corporate treasury disclosing a holding, or a government changing its stance.
Like political risk in a currency, this kind of news follows no release calendar. It can arrive at any hour, and when it does it can override the macro backdrop for days. Crypto's own media and communities amplify it faster and louder than is usual in traditional markets, which keeps bitcoin's volatility elevated even in weeks with nothing on the economic calendar.
Reading bitcoin on any given day
Put these together and bitcoin's price sits at the crossing of six forces: a fixed supply schedule, ETF flows that reveal institutional demand, a leveraged market prone to cascades, a sensitivity to Fed policy and US data that has grown with institutional ownership, a correlation with equities that comes and goes, and a stream of regulatory and adoption news that respects no calendar. On any given day some reinforce each other and some cancel out. Working out which one is dominant is the actual task, and it is the same task that what moves gold describes for a market with its own tangle of drivers.
The forces also fade at different speeds. A liquidation cascade often exhausts itself within a day; a run of ETF outflows or a change in the expected Fed path can weigh on the price for weeks; a regulatory decision can shift the picture for years. So when bitcoin drops four percent in an afternoon, the useful question is not just what happened, but which of these happened. NewsPips is built to help with that question: it gathers the coverage of each event into a single story, states which way the news currently leans for bitcoin with the stories behind that lean, and alerts you when the lean flips. The public bitcoin page shows the reading on a fifteen-minute delay, and how the readings are made is explained in plain terms. What it will not do is tell you what to trade.
