Fed rate hike lands at 1.99%, and Zcash's jump was not about it

The Federal Reserve raised rates a quarter point on Wednesday to 3.75-4.00%, its first increase since 2023, and crypto rose anyway. Zcash led with a 23% jump by CoinDesk's count, reported alongside Paradigm co-founder Matt Huang's disclosure that his firm owns the token and calls it a private complement to bitcoin.

“Inflation has been too high for too long.”

Fed rate hike: what the decision actually moved

We published a forecast yesterday morning and it can be marked. Across the five 2026 meetings the median range in the two hours around a decision was 2.00%, and we wrote that a priced hike had been doing less than an unpriced surprise. Here is what the decision actually produced:

• The two-hour window around the decision ran 1.99%, from $75,065 to $76,561.
• That window contained the whole day: 16 September's full range was also 1.99%.
• Net, bitcoin went from $75,768 at 17:00 UTC to $76,080 at 20:00, a gain of 0.41%.

So the priced event delivered 1.99% against a 2.00% median, while the unpriced Senate defeat two days earlier moved bitcoin 2.98% in its window. The gap between a shock and a scheduled event held, and it held to within one hundredth of a percentage point, which is closer than the method deserves.

The vote is the part nobody predicted. The committee went 12-0. In July it split 9-3 in favour of holding, and we wrote yesterday that four members would have to change their minds for a hike to pass. All of them did, and nobody dissented, CNBC reports.

The projections were not soft either. Sixteen of the eighteen participants expect another increase, and four of those see two more as possible; only two expect the committee to stop here. Warsh does not submit a dot. A description of this meeting as signalling limited further tightening sits awkwardly next to sixteen officials pencilling in more, and the market rose in front of it regardless.

Zcash, with the Fed taken out

Now Zcash, where the headline needs unpicking. Measured at 06:45 UTC, ZEC trades at $1,362.70, up 15.93% on the day, with a low-to-high swing of 19.7% over those 24 hours. Take the Fed out of it and the picture changes: at 17:00 UTC on Wednesday, an hour before the decision, ZEC stood at $1,269.07, so only 7.4% of the move has come since. Over seven days it is up 26.2% and over thirty it is up 167.8%.

Which is to say the rate decision is not why Zcash moved. A coin that has nearly tripled in a month was already running, and Huang's disclosure landed on a trend rather than starting one. The rest of the market did far less: bitcoin at $76,550 is up 0.90% on the day, ether 2.01%, Solana 2.95%, BNB 1.93% and XRP 0.68%, while total market value is actually down 1.71% over 24 hours.

What to watch next

That last number is worth holding. The market capitalisation fell while most large coins rose, which happens when the gains are concentrated and the long tail is not participating. This is the same breadth problem we measured on Tuesday, when the share of coins beating bitcoin improved only because bitcoin was falling faster than they were.

What to watch from here is flows rather than rhetoric. American spot bitcoin funds lost $135.8 million across the three sessions into Monday while ether funds took $307.7 million, and the first post-decision numbers will show whether institutional buyers read sixteen hawkish dots the way equities did. Our measurement that bitcoin now moves less on Fed days than it did a year ago survived its first live test, and one test is not a law.
