Bitcoin Weekly: Yen Intervention and US Inflation Set the Tone

Bitcoin posted its first weekly close above $80,000 in roughly four months, landing just after markets refocused on a fresh batch of U.S. inflation releases ahead of the Federal Reserve’s Sept. 16 meeting. The move comes as investors balance softer inflation prints against renewed pressure from a stronger labor market and ongoing policy uncertainty.

At the same time, analysts say BTC’s bounce still lacks the spot-market participation needed to decisively break out of the $80,000 area. On-chain and derivatives data point to a rally that has leaned heavily on futures positioning—an imbalance that typically increases the odds of volatility if macro conditions turn.

Key takeaways

• Bitcoin achieved its first weekly close above $80,000 since early May, according to TradingView data.
• U.S. CPI and PPI prints are due this week ahead of the Sept. 16 Fed decision; CME’s FedWatch Tool shows 0.25% hike odds at 58.4%.
• Japan’s record yen interventions coincide with a reported $79.57 billion drop in foreign reserves, raising questions about ongoing U.S. Treasury sales.
• CryptoQuant argues recent upside volatility was driven more by derivatives open interest than by spot/on-chain accumulation.
• Bitcoin’s weekly supertrend indicator turned “buy” for the first time since late 2025, echoing a pattern seen during the early-2023 recovery.

Inflation week before the Fed: what markets are betting on

Inflation data returned to the center of crypto sentiment after earlier employment news pushed risk assets lower. This week, the August Producer Price Index (PPI) is scheduled for release on Thursday, followed by August CPI on Friday.

Prior CPI figures offered a mixed backdrop: the August CPI print “matched market expectations” at 0.1% month-on-month and 3.4% year-on-year, following softer-than-anticipated June results. Even so, Fed leadership has continued to stress that recent improvement may not yet justify changing course. Speaking at the Jackson Hole economic symposium in late August, Federal Reserve chair Kevin Warsh said lower headline measures did not, by themselves, establish that underlying inflation trends were meaningfully improving.

That distinction matters for traders because the Fed’s policy reaction function depends heavily on “trend” inflation rather than isolated prints. In response to Warsh’s remarks and the broader data flow, markets shifted toward a higher probability of rate hikes for the Sept. 16 meeting.

According to CME Group’s FedWatch Tool, the consensus currently favors a 0.25% rate hike, with odds at 58.4%. This hawkish tilt intensified after last week’s nonfarm payrolls report, which came in “far stronger than expected” and included upward revisions to earlier figures. The U.S. economy added 162,000 jobs in August versus a prior estimate of 56,000.

A stronger labor market generally reduces pressure on the Fed to loosen policy—especially when core inflation remains above the Fed’s 2% objective. While some officials have discussed support for pausing rate hikes, the market is still focused on how PPI and CPI could reshape expectations in the days before the meeting.

Mosaic Asset Company suggested that the jobs report could still carry an equity-friendly angle through corporate earnings, but also warned that seasonality may complicate matters. It noted that September is traditionally equities’ weakest month and that volatility may rise into the Q4 period, with U.S. midterm elections adding another potential catalyst for turbulence.

Japan’s intervention record keeps yen and liquidity in focus

Beyond U.S. inflation, traders are also tracking Japan’s yen dynamics. Japan’s Ministry of Finance reported that foreign reserves fell by $79.57 billion from the end of July amid record currency intervention. The yen strengthened to around 155 per dollar and held that level during Monday’s Asia session.

Bloomberg previously reported that Japan may have relied heavily on selling U.S. Treasuries to fund these operations. That approach could have second-order effects for U.S. bond markets and for how long Japan can sustain intervention without drawing Washington’s response.

The concern extends to the Bank of Japan’s (BOJ) position. If yen weakness returns and further intervention becomes necessary, critics argue it could become harder for both the ministry and the BOJ to act within their constraints.

Polymarket data currently prices in a BOJ September rate increase, reflecting the idea that policy makers may need to tighten to defend the currency. With benchmark rates already at the highest level since 1995 at 1.0%, Polymarket is showing 98% odds of a 0.25% hike.

For crypto, these FX and rates headlines can matter because BTC and broader risk markets are sensitive to changes in USD/JPY, particularly where yen-carry trades and global liquidity conditions are concerned.

Derivatives surge without clear spot confirmation

Even as BTC reclaimed a key weekly milestone, analysts argue the underlying demand signal is still incomplete. CryptoQuant pointed out that the recent upside volatility was paired with sharp increases in derivatives open interest, suggesting that derivatives traders drove a large share of the move rather than spot buyers.

In one example, CryptoQuant reported that aggregate open interest rose from $25.2 billion to $27.53 billion in a single session—an increase of about $2.3 billion (+9.24%). On an hourly basis around 09:00 UTC, price action and open interest began expanding almost simultaneously, which CryptoQuant interpreted as evidence of new position-building.

At the same time, CryptoQuant said realized cap did not keep pace with the open interest jump. In its view, the rally had some spot/on-chain participation, but the dominant driver was futures leverage—creating a market structure that can unwind quickly if funding conditions change.

This imbalance shows up in how spot demand is tracking. CryptoQuant cautioned that spot demand remains negative and that it has been diverging from futures demand on a 30-day rolling basis. The platform also highlighted that spot BTC outflows increased further even after the rebound—its interpretation being that the rally did not yet translate into persistent spot accumulation.

Previous Cointelegraph coverage also flagged similar concerns, describing how apparent demand had turned negative as BTC’s dormant supply growth outpaced new issuance. For traders, the practical implication is that a sustainable breakout typically requires stronger spot absorption—conditions that remain uncertain as long as derivatives lead.

Liquidity walls around $80,000 and a bullish-but-testable trend signal

BTC’s weekly close above $80,000 marks a notable technical shift, but the $80,000 zone is not yet acting as reliable support. Sell-side liquidity continues to cluster just above the level, keeping price pinned within a narrower trading range.

CoinGlass data shows liquidity concentrated around $80,560, forming what the analysis describes as a thick wall of resistance. This helps explain why BTC has been unable to hold above $80,000 consistently despite the bullish weekly close.

Looking higher, on-chain-focused commentary from Glassnode previously identified additional dense liquidity bands—especially a band between $83,000 and $86,000. In its newsletter, Glassnode wrote that an upward impulse consumed some short orders but stopped short of the densest cluster of short liquidation “fuel” in that upper zone. Below spot, it said the move left intact a separate long liquidation band between $60,000 and $63,000, framing the current consolidation as a market trapped between boundaries.

Chart-watchers are also watching for a potential resolution direction. Jesse Olson, developer of the Markets Sniper trading suite, suggested BTC/USD could be repeating a bullish chart fractal from August 2023, with $76,000 described as a potential local reversal point.

Supertrend flips green: why the weekly indicator stands out

One of the clearest trend signals cited in the market commentary is BTC’s weekly supertrend indicator. Sunday’s weekly close flipped the indicator to green for the first time since November 2025, producing a “buy” signal.

The supertrend method uses average true range (ATR) and a multiplier to calculate a trendline, then issues a buy or sell signal based on how price interacts with that level. Weekly signals are closely watched by Bitcoin traders because, as the analysis notes, a weekly close above the supertrend line has not occurred during a bear market. The last time supertrend switched from red to green was in mid-January 2023, when BTC’s bear-market bottom at $15,600 was already about two months behind it.

That historical context is part of why some traders view this as more than a short-term signal. It also aligns with other indicators analysts cited recently, including BTC’s earlier weekly reclaim of its 50-week exponential moving average—an event described as historically important for long-term trend reversals after a prolonged downtrend.

What to watch next is whether the market’s key catalysts—U.S. CPI/PPI ahead of Sept. 16, and ongoing yen-liquidity developments tied to Japan’s intervention path—translate into stronger spot participation. If derivatives remain the primary driver while spot demand stays weak, the $80,000 breakout signal may stay vulnerable despite bullish trend indicators.
