According to Woofun AI, on September 30, the Bank of England released a warning report that drew intense market attention, unusually linking the immense pressure on sovereign bonds with borrowing risks in artificial intelligence development. This macro-level warning signal marks the intensifying dual anxiety of the traditional financial system in coping with emerging technology debt and government financing difficulties, while also providing a critical opportunity to re-examine Bitcoin's monetary attributes as an independent monetary asset free from policy control.

The monetary policy tightening trend of major global central banks constitutes the macro backdrop of the current high interest rate environment. Under the leadership of Federal Reserve Chairman Kevin Warsh, who officially took office on May 22, the Federal Reserve announced on September 16 an increase in its target interest rate range by 0.25 percentage points, settling the adjusted range between 3.75% and 4%. Meanwhile, the Bank of Japan set a new overnight call rate guideline of approximately 1.25% on September 18, stipulating that this standard would take effect from September 24. In Europe, the Bank of England announced on September 17 its decision to maintain the bank rate at 3.75%, despite three policymakers advocating for a further increase to 4%. These moves indicate that even as some central banks choose to hold steady, the global financing environment remains in a tightening state, and rising market yields inevitably intensify the tension in borrowing costs.

The surge in US Treasury yields and the dramatic fluctuations in Bitcoin's price directly reflect the market's repricing of risk premiums. Data compiled by Woofun AI shows that the 10-year US Treasury yield data released by CryptoSlate presents a significant upward trend, with the daily yield reaching as high as 5.29% on September 30, while the Federal Reserve's report released on September 30 indicated a yield of 5.26% on September 29. Since these two data sets correspond to different dates, their comparison highlights the rapid climb of yields in a short period. Against this backdrop, Bitcoin's price has similarly experienced sharp swings. As of press time, Bitcoin was trading at approximately $83,530; over the past 12 months, its price had hit an all-time high of $125,000 and also dropped to a low of $57,500. This enormous volatility reflects both investors' weighing between bond contract yields and Bitcoin's potential appreciation, and reveals the complex influence of multiple demand factors on asset prices.

Bitcoin's theoretical foundation as an independent currency is deeply rooted in Satoshi Nakamoto's vision presented in the whitepaper. The proposal aimed to establish an electronic payment system that operates without the involvement of any financial institution, allowing two parties to transact directly. Through a peer-to-peer network based on proof of work (PoW), Bitcoin replaced the traditional double-spending detection mechanism that relies on trusted intermediaries, all built upon specific security assumptions. This design makes Bitcoin's issuance mechanism fundamentally different from traditional authorities—its supply cannot be increased because a government needs to refinance or a central bank believes the economy needs more support. According to the protocol rules, Bitcoin's total issuance will ultimately be strictly limited to within 21 million coins. For users who wish to break free from the policy constraints of a specific issuer, choosing this asset with independently verifiable supply rules means they must bear the costs of market volatility and asset custody responsibilities, but they also gain a monetary asset independent of institutions dealing with energy shortages or borrowing cost problems.

On the AI agent payment infrastructure front, Lightning Labs' technological breakthrough provides critical support for Bitcoin's commercial application. In February of this year, Lightning Labs launched tools allowing software to pay API fees using Lightning payment functionality through the L402 protocol. This protocol combines Lightning payment technology with access credential functionality, enabling APIs to initiate payment requests, with agents responsible for paying the corresponding Lightning payments, and upon payment completion, unlocking the required resources. This mechanism extends Bitcoin's function beyond merely holding and waiting for liquidation—software buyers can pay fees immediately when data is needed without manually arranging subscription procedures, and service providers can charge for each individual request. In July of the same year, Lightning Labs released Wavelength, an alpha-stage toolkit designed to help developers and agents more easily achieve wallet integration. Initially, the tool was only used on test networks, with mainnet functionality accessible by invitation. Its design focus is on security, employing measures such as remote signing, restricted credentials, and spending limits, and keeping private keys and passwords outside agent channels to reduce the risk of fund leakage or misuse.

Traditional payment giants and technology companies are also actively positioning themselves in the AI payment sector, forming a fiercely competitive landscape. Mastercard (MA.US) announced on September 30 the launch of new trust and intelligence services for its Agent Pay project, including a scoring system for identifying AI-initiated transactions, which is currently being tested in the United States. Google (GOOGL.US) announced in September 2025 its AP2 framework supporting payments using credit cards, stablecoins, and bank transfers, recording user-authorized payment content through signed authorization methods. Coinbase (COIN.US) added stock trading functionality and x402 micropayment functionality in its agent-related announcement on September 22, allowing users to pay for data, models, and services within self-set limits. These traditional pathways provide options for simplified budget management for agents purchasing dollar-denominated services, making enterprises that pay expenses in dollars more inclined to receive dollars, thereby opening another path within the existing payment system.

In the machine economy, Bitcoin coexists and divides labor with the dollar and stablecoins. As CryptoSlate's recent report on stablecoins pointed out, the increase in software buyers may drive greater use of digital dollars rather than completely replacing it. However, Bitcoin's unique advantage lies in the fact that some users highly value independently issued currency and direct settlement methods, so they will continue to hold Bitcoin across different transactions. Agents that can temporarily convert dollar balances into Bitcoin for payment demonstrate Bitcoin's practical infrastructure; agents or enterprises that can earn, hold, and use Bitcoin embody a deeper monetary choice. These two choices can fully coexist—Bitcoin can play an increasingly important role in savings and settlement, while the dollar will still be widely used in pricing everyday services. Even without reaching the stricter definition of "hyperbitcoinization," this would be a major development for Bitcoin, marking its transformation from a mere investment product to a practical currency.

Sovereign debt pressures combined with AI adoption are jointly driving the future of Bitcoin's monetization. The Bank of England warned that debt-financed AI investment would increase the financial system's exposure risk, and if expectations for AI-driven productivity gains fall short, the impact could even spread to sovereign financial markets. It is precisely the technology creating new payment users that is developing within the alternative credit system that Bitcoin provides. The more reasons to hold Bitcoin and the more ways to use it, the more these two factors tend to reinforce each other. Converting this opportunity into actual widespread adoption ultimately depends on the choices of people and businesses. If agents primarily use stablecoins or authorized credit card balances for payments, machine commerce will modernize fiat currency; if enterprises and their software begin to hold Bitcoin and use it as a measure of value, the transformation of the monetary system will have a more solid foundation. When Bitcoin users choose to continue holding this transferable currency, its development opportunities will grow accordingly—this is not merely the promotion of payment functionality, but a profound transformation at the level of monetary application.
