Inflation at 2.7%, Coinbase Expands Into Stocks & BoJ Raises Rates
Markets continue to chop sideways, with Bitcoin ranging between $84K and $92K and Ethereum trading below $3K, reflecting a lack of conviction and thin liquidity.
In other news, Coinbase is making a major push beyond spot crypto, expanding into stock trading, prediction markets, Solana DEX trading, custom stablecoins, and a broader suite of financial products. Visa launched stablecoin settlement in the US using Circle’s USDC on Solana, while Ark Invest added more BitMine shares, continuing its exposure to crypto-linked equities.
On the policy front, President Trump is set to interview Fed Governor Christopher Waller as a potential next Fed Chair, and stated that the new chair would cut rates by a lot. The Bank of Japan is preparing to raise its short-term policy rate to 0.75% from 0.5%, adding pressure to global markets. Meanwhile, the SEC concluded its investigation into the Aave Protocol, and clarified that broker-dealers must maintain control of crypto private keys to comply with customer protection rules.

Market Commentary
Bitcoin
$BTC tested weekly resistance at $92K but failed to reclaim it and dropped to $85K. Choppy price action followed, with BTC printing a sharp $3K green candle on the 4H timeframe, only to erase those gains shortly after. Bitcoin is now trading around $87K.
The Bank of Japan decisioncontinues to play a key role in short term price movements. Overall, nothing has materially changed.
The macro environment still needs to remain supportive for Bitcoin to attempt the next leg higher.


Ethereum
As mentioned in the previous edition, $2,900 support held for $ETH, after which Ethereum moved up to test $3,400. However, it lacked the strength to break out, saw a strong rejection, and is now trading below weekly support. For now, $2,900–$3,400 defines the active range.
Just like Bitcoin and the broader market, the macro environment needs to remain supportive for Ethereum to attempt the next leg higher.

Bitcoin dominance increased to 59.3 (+0.6% weekly).
In traditional markets:
- S&P 500 down 2.60%
- NASDAQ down 4.12%
- Gold up 0.84%
The total crypto market cap stands at $2.93 trillion, down roughly 4.57% from $3.07 trillion. The Fear & Greed Index is at 17 (Extreme Fear), big drop from last week’s 26 (Fear).
What's Next?
The CPI report came in softer than expected, with November inflation at 2.7% YoY versus 3.1% expected, while U.S. core CPI slowed to 2.6% in November, the lowest level since March 2021. This is a bullish sign for risk assets and reinforces the broader disinflation trend.
On the other hand, the Bank of Japan’s rate hike to 0.75%, the highest level in three decades, remains a bearish overhang for crypto, adding uncertainty to global risk assets and liquidity expectations.
Futures markets continue to de risk, with open interest trending lower and funding rates near neutral. This signals a lack of speculative conviction rather than forced deleveraging. Leverage is no longer driving downside, but it is also not supporting upside. Although the expected Fed cut has already materialized, the crypto market appears somewhat exhausted following a series of macro events.
At present, capital within crypto is leaning toward risk off strategies, such as yield farming and parking funds in stablecoins. With no major macro catalysts expected into year end, we expect continued choppy price action and no clear directional trend in the near term.
