The Week of Inflation

Markets focus on the Fed’s September 17 meeting, with a 94% probability of a 25bps rate cut. U.S. labor data show weakness, with initial jobless claims at 263K and 911K fewer jobs added for the year ending March 2025. Euro area inflation is expected at 2.1% and U.K. at 3.8%, while China slows with retail sales up 3.4% YoY and unemployment at 5.3%. ETH/BTC is at 0.039 despite Ethereum hitting $4,957 last week. Ethereum’s stablecoin supply reached $166B, led by USDT ($87.8B) and USDC ($48B), while Hyperliquid’s USDH moves toward GENIUS-ACT compliance.

Daily Updates:

  • This week’s attention is focused on the Federal Reserve’s September 17 meeting, where policymakers are set to decide on potential rate cuts. Market expectations are heavily skewed toward a 25 basis point reduction, with CME futures implying a 94% probability of such a move.
  • President Donald Trump reported that he expects “a big cut” at the meeting on Wednesday, according to Bloomberg, despite the widely expected 25bps reduction.

  • Despite the decision coming amid inflation readings that remain well above the Fed’s 2% target, with August’s CPI at 2.9% YoY, a slew of recent labour market data releases has indicated greater weakness in the labour market than was previously thought: Initial Jobless Claims rose to 263K in the first week of September, the most since October 2021.
  • The Bureau of Labour Statistics also revised down job growth, reporting 911K fewer jobs created for the year ending March 2025 than was previously estimated.

  • On the same day as the U.S. Federal Reserve’s policy decision, both the euro area and the U.K. will release their inflation data.
  • Euro area headline inflation is expected to tick up to 2.1% in August, while U.K. inflation is forecast to remain steady at 3.8%.

  • China’s economy showed signs of slowing in August 2025. Retail sales grew 3.4% YoY, below market expectations of 5.0% and down from 3.7% in July, marking the slowest pace since November 2024 and the third consecutive month of deceleration.
  • At the same time, China’s surveyed unemployment rate edged higher to 5.3% from 5.2% in July, the highest level since February 2025.

  • The ETH/BTC spot price ratio remains under pressure, despite ETH's explosive summer rally and growing institutional adoption. Following July and August’s historic surge, ETH climbed to a new all-time high of $4,957 before easing to around $4,600, but the ratio sits at just 0.039.
  • Despite a small early morning slide in spot prices at the beginning of the week, derivatives markets positioning remains largely unchanged from the weekend.
  • Friday saw a recovery in sentiment across the board as BTC and ETH volatility smiles recovered from their sharp skew towards OTM puts. This was matched by a move higher in funding rates as traders price out what remained of the demand for short exposure over the weekend.
  • A small lift in front-end volatility levels is the only hint of the pivotal FOMC meeting ahead on Wednesday – following the last week’s CPI release, there is now little uncertainty priced-in by the market over the decision that the Fed will take.
  • However, the divergence between outright volatility levels between the two majors remains at extended levels: ETH volatility is still nearly two times that of BTC across the term structure, despite the levels of volatility implied by both options markets falling over the last week.

  • According to onchain data, Galaxy Digital has purchased 1.2M SOL (approximately $306M) in the last 24 hours, bringing its total purchases over the past five days to around 6.5M SOL (approximately $1.55B).
  • This follows Galaxy’s collaboration with Multicoin Capital and Jump Crypto on a $1.65B private placement in Solana treasury accumulation strategy Forward Industries.
  • SOL is down close to 5% over the past 24hrs, in line with the broader market, but remains up more than 24% for the month, with over half of those gains coming in the past week.

  • Native markets has secured the bid for Hyperliquids upcoming stablecoin, USDH.
  • They have proposed to reinvest the stablecoin reserve yield back into Hyperliquid projects with 50% towards USDH promotional material and expansion while 50% will go to the Hyperliquid Assistance Fund which is primarily used to buy back $HYPE tokens on the open market.
  • USDH will be GENIUS-ACT compliant across the US and EEA, fully backed by cash and US Treasury equivalents, with off-chain reserves initially managed by BlackRock and on-chain reserves overseen by Superstate via Bridge.

  • Ethereum’s stablecoin ecosystem reached a new milestone this week, with total supply on the network hitting a record $166B as of September 13, up from $149B a month earlier.
  • USDT continues to dominate, accounting for $87.8B, followed by USDC at $48B.
