Key Takeaways

This week (7–12 September; US markets closed on 7 September for Labour Day) macro pricing shifted fully towards inflation and interest rates. August CPI stood at 3.4% year-on-year, with a 0.4% month-on-month rise. Core CPI rose 0.3% month-on-month, exceeding the 0.2% forecast, while the year-on-year reading fell to 2.4%. Petrol prices surged roughly 3.9% month-on-month, and energy remained sharply higher year-on-year. Market pricing for a 25-basis-point rate hike at the 15–16 September FOMC meeting climbed to around 90%, and the 10-year US Treasury yield rose to approximately 4.96%–4.98%. Oil prices briefly neared US$100 and tested higher levels. Combined with rising yields, US equities closed lower across the week: the S&P 500 fell about 0.8%, the Dow Jones by roughly 1.6%, and the Nasdaq by around 0.7%.

The crypto market cooled in tandem. Bitcoin retreated from roughly US$80,000 at the start of the week to a low near US$76,000, trading at US$76,600–77,300 over the weekend, representing a weekly loss of 3%–4%. Ethereum followed the pullback, with its trading centre of gravity moving down to around US$2,400. Spot Bitcoin ETFs recorded net outflows of approximately US$463 million this week, ending three consecutive weeks of inflows. Ethereum ETFs saw net inflows of about US$197 million. The FOMC meeting coincides with procedural votes on the Clarity Act next week, and volatility is expected to remain elevated.

I. Macroeconomics and Traditional Finance: Core Inflation Surprises to the Upside, September Rate Hike Almost Fully Priced In

The main theme across traditional finance (TradFi) this week was the interplay between oil prices, bond yields and CPI, compressing valuations for risk assets.

1. August CPI shows persistent price stickiness, with growing fears of energy pass-through to core inflation Released on 11 September, August CPI data showed the headline index rose 0.4% month-on-month and remained at 3.4% year-on-year, broadly in line with expectations. Core CPI increased 0.3% month-on-month, above the 0.2% consensus forecast, and fell from 2.5% to 2.4% year-on-year. Petrol climbed roughly 3.9% month-on-month, contributing a large share of the monthly rise, while energy was up around 16% year-on-year. The data suggests the oil price shock is no longer purely a one-off factor, and the monthly acceleration in core readings makes it harder for the Federal Reserve to hold rates steady.
2. Rate-hike probability rises to circa 90%, long-dated yields approach 5% Following the CPI release, Fed funds futures priced in roughly a 90% chance of a 25-basis-point increase at the 16 September meeting. A hike would lift the target policy rate range to 3.75%–4.00%. The two-year yield rose to approximately 4.57%, and the 10-year yield climbed to 4.96%–4.98%, a marked increase from the prior week’s ~4.78%. Oil strengthened mid-week amid tensions around the Iran nuclear deal, briefly touching triple digits. Although oil retreated on Friday, real interest rates and risk premia both came under pressure.
3. Weekly US equity performance: post-holiday sequential pullback, Friday rebound fails to erase weekly losses For the week ending 11 September:

• S&P 500 closed at 7,656.98, down roughly 0.8% on the week
• Dow Jones Industrial Average closed at 52,573.29, down approximately 1.6% on the week
• Nasdaq Composite closed at 26,333.04, down around 0.7% on the week

Markets weakened from the first trading day after the holiday due to rising oil prices, with three down days across the subsequent four sessions. On Friday, falling oil prices and CPI figures that did not massively surprise sent the three major indices rebounding by 0.9%–1.0%, yet gains were insufficient to recover weekly losses. Investors grew more cautious over rate-sensitive sectors. Large-cap tech stocks proved relatively resilient, while cyclicals and high-growth names experienced amplified volatility.

II. Crypto Market Microstructure: Break below US$80,000, Prices and Capital Flows Cool Simultaneously

The crypto market moved from consolidation at elevated levels into a pullback driven by macro repricing this week.

1. Latest market movements: Bitcoin falls to US$76,600–77,300, Ethereum corrects in tandem Bitcoin started the week at roughly US$79,800–80,300 and gradually weakened after the Labour Day break. It dipped to US$76,000–76,500 on 10 September, staged an intraday rebound close to US$80,000 on 11 September before slipping again, and traded around US$76,600–77,300 towards the weekend. Relative to the prior week’s closing level of about US$79,800, Bitcoin lost 3%–4% this week, and the US$80,000–82,000 zone has temporarily turned into resistance.

Ethereum pulled back in parallel, with its trading centre of gravity falling from last week’s ~US$2,480 to roughly US$2,400. Its momentum was weaker than the sharp rally seen in mid-to-late August, indicating investors are inclined to reduce risk exposure ahead of the rate decision window.

2. Market structure: Bitcoin ETFs flip to outflows, capital diverts into Ethereum ETFs Spot Bitcoin ETFs recorded net outflows across all four trading days from 8 to 11 September, totalling around US$463 million. The single-day outflow on 10 September reached US$283 million, the largest of the week. This halted three straight weeks of inflows totalling approximately US$3.8 billion. Ethereum ETFs saw net inflows of about US$197 million this week, mainly driven by a US$216 million single-day inflow on 11 September. Capital displayed a short-term divergence pattern: redemptions from Bitcoin ETFs and partial absorption into Ethereum ETFs. Overall sentiment across crypto ETFs remained cautious, with no broad recovery in risk appetite.

III. In-Depth Industry Analysis: Rate Hike Almost Locked In; Regulatory Vote and Policy Meeting Fall in the Same Week

The core tension in crypto markets this week lay in the materialisation of macro tightening expectations overlapping with an active window for regulatory legislation.

1. Institutional capital shifts from aggressive accumulation to risk-driven rebalancing The heavy ETF inflows seen in late August and early September were partially reversed this week. The break below US$80,000 coincided with four consecutive days of Bitcoin ETF outflows, showing that marginal buyers from the previous rally are highly sensitive to interest rates. Friday’s inflow into Ethereum ETFs represents structural reallocation rather than a broad recovery in risk appetite. Ahead of the FOMC meeting, whether spot demand stabilises again in the US$76,000–78,000 range will determine whether this pullback marks the completion of rate-hike pricing or a breakdown of the underlying trend.
2. Revised Clarity Act text published; uncertainties remain around the 15 September procedural vote Senator Lummis released the roughly 630-page revised bill text on 10 September incorporating numerous amendments. Disagreements persist on DeFi registration, stablecoin yield provisions and ethical clauses. The Senate requires 60 votes to open debate. Republicans currently hold 53 seats, meaning cross-party support is still needed. The 15 September vote falls almost alongside the FOMC decision: the former determines whether regulatory narratives can continue to be priced in, while the latter sets liquidity costs. Even if the procedural vote passes, the bill will not immediately become law. Should the vote fail, the probability of enactment in 2026 will drop markedly.

SunX Research Comment

This week the market completed a shift from rate-hike speculation following strong employment data to core inflation cementing expectations of a rate rise. Bitcoin’s fall below US$80,000 is fundamentally a repricing of the interest-rate path rather than a sudden deterioration in on-chain fundamentals. The switch from inflows to outflows in ETFs indicates institutional participants remain active, yet they are no longer willing to bear high volatility at elevated levels ahead of the policy meeting. The key focus next week is not whether Bitcoin can instantly reclaim US$80,000, but whether spot inflows emerge near US$76,000 once the rate hike is delivered.

IV. SunX Trading Strategy Guide: Positioning for the Dual Shock of the Policy Meeting and Legislative Vote

With Bitcoin retracing to roughly US$77,000, US equities finishing the week lower and the September rate hike nearly fully priced in, chasing rallies or betting on a one-sided crash are not optimal approaches. For SunX high-net-worth clients and professional traders, strategy recommendations for this week centre on reducing leverage, managing event-driven volatility and retaining capacity for buybacks:

1. Leverage central exchange liquidity to hedge FOMC and Clarity Act risks via futures 15–16 September brings both the regulatory procedural vote and interest-rate decision, creating conditions prone to whipsaw price action after data releases. Investors holding spot assets may deploy SunX futures for partial hedging within the US$76,000–78,000 range to prevent medium-term positions from being disrupted by single-day macro shocks. If the rate hike meets expectations and the statement is neutral, alongside moderating ETF outflows, short hedges can be unwound gradually. Should the dot plot turn markedly hawkish or the Clarity Act vote stall, profit protection should take priority. SunX’s ultra-low-latency matching engine helps minimise slippage around policy announcements.
2. Cut speculative long positions in high-volatility assets; allocate part of holdings to yield-bearing instruments We recommend reducing speculative trades on low-liquidity altcoins. Convert some realised profits into compliant stablecoins and lock in relatively stable passive yield via SunX Earn. Core allocations should remain focused on Bitcoin and Ethereum. The medium-term thesis has not been invalidated by one week of outflows, though short-term price discovery is controlled by interest-rate and legislative calendars. Holding cash-generating assets preserves firepower for repurchases amid post-decision volatility, avoiding forced stop-losses during market shocks.

Closely monitor the FOMC statement and dot plot, the outcome of the Clarity Act procedural vote, and whether Bitcoin ETFs switch back from persistent outflows to inflows.
