The Bank of Japan (BOJ) took markets by surprise on Friday when it raised its key policy rate by 0.25 percentage points to 0.75%, the highest in nearly three decades. Contrary to expectations that such tightening would bolster the Japanese yen, the currency instead plunged sharply against the US dollar and other major currencies. This unexpected weakness in the yen triggered significant shifts across global financial markets, including in the Bitcoin sector.

Yen’s Drop Spurs Bitcoin Rally Above $88,000

In the hours following the BOJ announcement, Bitcoin rose above the $88,000 mark, showing resilience amid the volatile environment. Usually, a higher interest rate in Japan would attract capital back to yen-denominated assets, but in this instance, investors sold the yen aggressively. According to market sources, this has made carry trades more attractive again, where investors borrow yen at low rates to buy higher-yielding assets like Bitcoin.

Bitcoin’s price dipped below $85,000 late Thursday before rallying to exceed $89,000 in early Friday US market hours but found resistance around that ceiling. The overall trading pattern suggests bulls are battling a recurring sell pattern during US trading hours while buyers gain strength afterward. The aggregate funding rate for Bitcoin futures across exchanges jumped to 0.085%, marking the highest level since November 21 and indicating increased buying pressure backed by leveraged long positions. This suggests investors are more confident in Bitcoin’s medium-term prospects following the BOJ move.

Institutional and Stock Index Impacts Loom Over Bitcoin-Hoarding Giants

However, the blockchain bull run comes with headwinds. Michael Saylor’s publicly traded firm, Strategy, which holds a significant Bitcoin treasury, faces possible exclusion from MSCI and other major stock indexes. MSCI is considering dropping companies with over 50% of their assets in digital currencies. Analysts estimate that the exclusion could cost Strategy up to $9 billion in reduced demand for its shares, adding pressure on the sector’s overall perception among mainstream investors.

This potential removal from global benchmarks reflects a growing tension between traditional finance gatekeepers and crypto-related firms. Given Strategy’s dominance in Bitcoin holdings, any hit to its stock could ripple across the crypto ecosystem, influencing sentiment and investment flows.

Citi Maintains Bullish Outlook Despite Fall in Token Prices

Despite the recent price pullbacks, Wall Street banks such as Citigroup remain constructive on digital assets stocks. Citi refreshed coverage on the sector, maintaining a 12-month Bitcoin price target of $143,000, implying nearly 62% upside from current levels around $88,000. Their positive outlook is driven by expectations of accelerated digital asset adoption, potentially spurred by forthcoming U.S. legislation that could clarify regulations and boost institutional interest.

Additionally, while some stocks tied directly to Bitcoin mining and crypto services have endured downward pressure—for example, Riot Platforms closed the week down 7%—Citi’s analysts argue that the broader ecosystem’s fundamentals remain intact. Longer term, the sector’s growth aligns with increased usage of blockchain technologies and expansion of digital finance.

Market Dynamics Amid External Developments

Bitcoin’s price action also occurs amid other notable occurrences in crypto and finance. Notably, the retirement announcement of Senator Cynthia Lummis, known as one of crypto’s staunchest allies on Capitol Hill, adds an element of political uncertainty. Meanwhile, cryptocurrency compliance efforts are intensifying, exemplified by a $536,853 fine levied on a crypto dealer for anti-money laundering failures in Canada, highlighting regulators’ persistent scrutiny.

Furthermore, in the broader tech-related segments, Oracle’s stock gained over 6% following reports of TikTok partnerships, sparking a ripple effect of optimism across AI and crypto-adjacent equities. This helped balance out risk sentiment in volatile markets.

What to Watch Next

Looking ahead, Bitcoin’s ability to hold above the $88,000 mark while overcoming recurring US session sell pressure may be key for further rallies. Investors will closely monitor regulatory headwinds especially relating to institutional holders and stock index compositions together with macroeconomic developments such as the BOJ’s policy stance. Should Bitcoin break decisively above $90,000, it could validate Citi’s bullish price target and attract fresh capital inflows.

Simultaneously, the weakening yen could sustain carry trade flows into risk assets, prolonging Bitcoin’s recent momentum. Conversely, uncertainty over regulatory framing for crypto companies and potential erosion of demand for bitcoin-heavy stocks like Strategy may impose near-term constraints on price appreciation.

Shifting Forces in Bitcoin’s Path

This week’s BOJ rate hike and ensuing yen depreciation have created a complex but fertile environment for Bitcoin. The cryptocurrency’s rise above $88,000 supported by leveraged futures longs contrasts with emerging challenges faced by major market participants’ stock inclusion status. Meanwhile, bullish institutional forecasts provide a supportive narrative even as regulatory scrutiny tightens. Investors should stay alert to how these evolving dynamics interact, as they are likely to shape Bitcoin’s trajectory in the coming months.
