Bitcoin faces an eight-year rates test as the BOE unwinds £368 billion

The Bank of England (BOE) announced a plan to remove £368 billion of gilts held for monetary‑policy purposes by September 2034. The unwind will proceed through bond maturities and a modest level of active sales, creating a gradual tightening of financial conditions that could influence risk‑on assets such as Bitcoin.

BOE unwind schedule

The BOE will let the remaining gilt portfolio decline by an average of £46 billion per year via maturities and will conduct about £20 billion of annual active sales. This follows a prior separation of £120 billion of longer‑dated gilts to back banknotes.

Market reaction

Following the announcement, the 10‑year gilt yield fell more than 7 basis points and the 30‑year yield dropped nearly 10 basis points. The BOE also paused active purchase‑fund (APF) auctions while reviewing a possible arrangement with HM Treasury and the Debt Management Office, with operational details expected by April 2027.

Implications for Bitcoin

Bitcoin was trading near $78,000 on the day of the announcement. The BOE’s gradual quantitative tightening adds a slow‑burn pressure on long‑term yields, a factor that historically affects crypto risk appetite. However, the immediate market response was muted, and the longer‑term impact on Bitcoin will depend on whether the predictable central‑bank withdrawal translates into broader yield increases and reduced risk appetite.

Broader context

The BOE estimates that quantitative tightening contributed 20‑30 basis points to a roughly 200‑basis‑point rise in long‑term gilt term premia since 2022, with most of the increase driven by global uncertainty, sovereign issuance, and structural demand shifts. International research suggests that US monetary tightening can depress a common crypto‑market factor, offering a limited analogy for the BOE’s actions.
