Crypto: Inflation, the Fed and Iran set the tone for the week of September 8

Crypto markets are heading into a week centered on four US events: Wall Street’s reopening on September 8 after a weekend of tensions between Washington and Tehran, a closed-door Fed meeting the same day, a Treasury debt buyback on September 9, followed by PPI and CPI releases on September 10 and 11. The Bureau of Labor Statistics’ official calendar confirms that both inflation reports will be released at 8:30 a.m. New York time. After August’s strong jobs report, the market now assigns roughly a 57% probability to a Fed rate hike in September.

Crypto: Wall Street reopens with Brent near $100

US cash markets remained closed on Monday, September 7, for Labor Day. Their reopening on Tuesday will therefore provide the first full reaction from US equities to the new tensions between the United States and Iran over the weekend. Bitcoin, of course, never closed.

This setup extends the macro week already followed by Bref Crypto, which began with US employment data and bond yields.

The oil backdrop has clearly deteriorated. Available data put Brent at around $97.47 a barrel on Monday and WTI at $92.26 after further US strikes against Iranian tankers and retaliatory action by Tehran in the Strait of Hormuz region. Maritime traffic through the strategic passage has also declined.

For crypto, the problem is not solely geopolitical. Persistently high oil prices fuel inflation expectations, potentially push bond yields higher and reduce the Fed’s room to pause.

Bitcoin was trading around $79,500 on Monday, while Ether remained near $2,500. The market therefore avoided another massive liquidation over the weekend, but it is entering Tuesday with several factors that Wall Street has not yet fully priced in.

The closed-door Fed meeting is not the FOMC

The September 8 event has generated considerable discussion on social media. It nevertheless needs to be named correctly.

The Federal Reserve has indeed scheduled a closed meeting of the Board of Governors at 11:30 a.m. Washington time. The official agenda refers to “the review and determination of the discount and advance rates to be charged by the Federal Reserve Banks.”

This is not the FOMC meeting that will decide the US policy rate.

The Fed also notes that this type of Board meeting is generally scheduled in advance and takes place at regular intervals. A comparable meeting already appears several times in its 2026 calendar.

The distinction is important to avoid false suspense around an alleged secret meeting intended to raise rates on Tuesday. The Fed funds rate will be decided at the September 15–16 FOMC meeting.

The September 8 meeting is nevertheless worth watching. The discount rate provides direct access to credit from the Federal Reserve Banks. A revision could offer an additional indication of the Fed’s institutional tone, but it should not be confused with a monetary policy decision on the policy rate.

In other words, Tuesday may produce information. It will not deliver the decision the market is really waiting for.

Treasury to buy back up to $12.5 billion on September 9

On Wednesday, the US Treasury may buy back up to $12.5 billion of outstanding securities.

The figure is official. In its calendar published during the August Quarterly Refunding, the Treasury scheduled a cash management buyback for September 9 involving nominal bonds maturing in approximately one month to two years. The operation will take place between 1:40 p.m. and 2 p.m. New York time, with settlement the following day.

However, a common shortcut in crypto should be avoided: this is not $12.5 billion in Fed QE.

The Treasury is buying back certain older securities to manage its cash and improve the functioning of the bond market. It may issue new debt at the same time. Public debt will therefore not automatically fall by $12.5 billion.

The Treasury even specifies that its buyback program is not designed to respond to episodes of acute market stress.

That does not rule out a market impact. By buying back certain securities, Washington can improve their liquidity, alter collateral availability and temporarily influence yields. Bitcoin remains sensitive to major moves in the bond market. Bref Crypto had already observed this resilience from BTC despite rising global yields.

Another factor: on August 19, the Treasury announced that it would at least double the size of liquidity-support buybacks for longer maturities, increasing the maximum from $2 billion to at least $4 billion per operation starting September 9.

This is not a money printer. It is not insignificant either.

PPI begins the inflation test on Thursday

The first major inflation reading arrives on Thursday, September 10, at 8:30 a.m. with the August Producer Price Index.

The PPI measures the prices received by US producers. It therefore comes earlier in the supply chain than the CPI: a sustained rise in production costs can eventually be passed on to consumers, although transmission is never automatic.

The latest data provide a fairly tense starting point.

In July, headline PPI was unchanged month over month, but was still up 4.7% year over year. The measure excluding food, energy and trade margins also rose 4.7% over 12 months.

This high annual figure explains why investors will look beyond the simple monthly change.

Services also matter. In July, their index rose 0.2%, while falling energy prices drove a 0.7% decline in goods.

With oil back near $100, the market will be watching primarily to see whether cost pressures are beginning to spread beyond energy.

A hotter-than-expected PPI would probably reinforce the restrictive interpretation already supported by the jobs report. A slowdown, by contrast, would give risk assets some breathing room.

Bitcoin does not need the PPI to be perfect. It mainly needs to avoid another surprise that would push US yields sharply higher.

Friday’s CPI carries more weight

Friday, September 11, will probably be the most important event of the week.

August CPI will be released at 8:30 a.m., exactly four days before the FOMC meeting begins. The latest available reading puts US inflation at 3.4% year over year, while core inflation, excluding food and energy, stands at 2.5%. Month over month, CPI rose 0.1% in July and core CPI rose 0.2%.

The market consensus provided expects headline inflation to remain close to 3.4% in August, while core inflation could slow slightly to around 2.4%. These are forecasts, not settled figures.

This is why the statement that “CPI will confirm the Fed’s decision” needs to be qualified.

The figure will carry enormous weight. It will not decide the matter on its own.

The Fed will also consider employment, wages, inflation expectations, financial conditions and the current rise in energy prices. After 162,000 jobs were added in August, compared with a much lower consensus, the labor market has already given monetary policymakers more room to remain restrictive. Bitcoin had, in fact, fallen below $80,000 immediately after that NFP report.

CPI is therefore the second piece of the puzzle.

Oil also complicates the inflation picture

There is another important nuance: the figures released on Thursday and Friday concern the month of August.

The new strikes that took place in early September and Brent’s rise toward $97 will therefore not be fully reflected in these data.

That does not mean the Iran–US war will have no impact. The conflict has lasted for several months, and Brent has already risen by around 35% since the end of February, according to the cited data. Part of the energy shock has therefore already entered transportation and production costs, as well as some consumer prices.

But the weekend’s new escalation is primarily a problem for the coming months.

Suppose August CPI slows slightly on Friday. The market could view that as an argument for a Fed pause. At the same time, Brent at $100 or higher could push future inflation expectations in the opposite direction.

That is what makes this week less binary than a simple “good CPI = Bitcoin up” equation.

The market will have to distinguish between inflation already measured and inflation it is beginning to anticipate.

And so will the Fed.

Bitcoin remains caught between inflation and yields

Bitcoin’s reaction to Friday’s NFP has already offered an indication.

BTC had climbed above $82,000 before falling back below $80,000 when the employment data increased the probability of another tightening move. The mechanism is now well known: higher expected rates, rising bond yields, a stronger dollar and pressure on assets that do not generate yield.

That relationship is not mechanical, however.

Bitcoin has also recently shown an unusual ability to hold up while global bonds sold off sharply. Its correlation with gold has risen again, while its correlation with the Nasdaq has declined. The market is therefore beginning, at times, to treat BTC as a scarce monetary asset rather than solely as a highly speculative technology asset.

This week will test that shift directly.

Lower inflation and falling rate expectations would naturally create a more comfortable environment for Bitcoin ETFs, crypto stocks and altcoins. Conversely, higher PPI and CPI readings combined with expensive oil could lead the market to raise the probability of another rate hike.

At present, the market estimates that probability at around 57% for September. There is therefore no firm consensus.

The market is almost evenly split.

The real deadline comes on September 15–16

This week is mainly setting up the next one.

The Fed will hold its actual FOMC meeting on September 15–16, with the decision released at 2 p.m. on Wednesday, September 16, followed by a press conference at 2:30 p.m. The meeting will also include new economic projections.

Before then, the market will have absorbed the employment data, PPI, CPI, new oil-price movements and two major Treasury operations.

Barclays had already revised its scenario, anticipating two additional rate hikes in 2026, including one in September. Bref Crypto detailed Barclays’ scenario change. The bank obviously does not have the final say; this week’s data can still alter expectations.

For crypto holders, the calendar is therefore less dramatic than it may appear, but probably more important.

September 8 does not conceal a surprise Fed decision. The Treasury’s $12.5 billion buyback is not disguised QE. And CPI alone will not guarantee either a hike or a pause.

Taken together, however, these events will give the market a much clearer reading of the US trajectory: inflation, yields, liquidity and rates.

Bitcoin is entering this sequence around $80,000. The question this week is not whether one figure will make it “explode” or “collapse.” It is simpler: will the data finally allow the market to choose between another rate hike and a Fed pause?
