美国国债收益率升至5.28%，比特币与标普500指数脱钩：这对你的投资组合意味着什么

10-year U.S. Treasury yield rose to 5.28%: highest level since 2002

As of October 2, 2026, the U.S. 10-year Treasury yield was at 5.28%, setting the highest closing record since May 15, 2002. At the same time, the price of Bitcoin remained at around US$84,900, and its trend and independence from the U.S. stock market reached a new high in recent years. Together, these two figures describe the market landscape German investors are in this weekend: risk-free yields are returning and the cryptocurrency market is no longer drifting as it has in past years.

This article will analyze these data against specific background, clarify the established reasons behind it, and discuss its implications for buying strategies, holding cycles, leverage use, and asset custody.

According to daily treasury bond yield curve data released by the U.S. Treasury Department, the 10-year treasury bond yield rose to 5.28% on October 2, compared with 5.24% on October 1. The current highest reading this year came on September 30 at 5.29%. To assess how rare this level is, we conducted a comprehensive evaluation of the official daily series for a total of 6,692 trading days from January 3, 2000 to October 2, 2026. During this period, the last time a yield of 5.28% or higher occurred was May 15, 2002. In the nearly 24 years since then, such high yields have never been seen in a single trading day. In 2026 itself, there are currently only two days (September 30 and October 2) to reach this level.

The yield curve shows the return on bonds of the same issuer over different maturities. This curve is the benchmark that all other investments must be measured because government bonds in the largest economies are seen as the lowest-risk alternative available.

Performance at the long-term end of the yield curve: the 20-year period is higher than the 30-year period

Looking at the data for each specific period on October 2, we can see the distribution of pressure: the 2-year period is 4.83%, the 5-year period is 5.06%, the 7-year period is 5.17%, the 10-year period is 5.28%, the 20-year period is 5.67%, and the 30-year period is 5.63%.

The end of the curve is prominent. The yield on 20-year bonds is higher than that on 30-year bonds, a pattern that is often attributed to the lower liquidity of 20-year notes. But what's more important for the crypto market is the steepness of the overall curve: a difference of 0.80 percentage points between 2 and 30 years. The market demands significant premiums for long maturities, which puts pressure on investments whose value is realized far in the future.

In addition, the 30-year yield is also of historical significance. In the above-mentioned daily series starting from January 3, 2000, the last time it reached 5.63% or more before 2026 was on July 13, 2001, when it was 5.64%.

German government bond yield 3.66%: Interest rate spread with the US dollar zone

For German investors, cross-comparisons of the local currency zone are crucial. In its daily listing of federal securities yield curve with a remaining maturity of 10 years, the Bundesbank reported a figure of 3.66% on October 1, 2026, following 3.64% on September 30 and 3.68% on September 29.

This resulted in a spread between 10-year U.S. bonds and 10-year German bunds of about 1.6 percentage points. Any investor who does not want to hold U.S. dollars and invest in euros will receive a return well below the 5.28% in the headline. This makes the competitive relationship with the cryptocurrency market in Germany's investment portfolio clearer: the 3.66% price-risk-free benchmark becomes the criterion for measuring every investment decision.

Correlation between Bitcoin and U.S. stocks: Falling to lowest level since 2015

In addition to interest rates, the relationship between Bitcoin and U.S. stocks has also changed. André Dragosch, head of European research at asset management firm Bitwise, said on September 30, 2026:"The decoupling of trends between the S & P 500 and Bitcoin is the strongest in eleven years." He pointed out that the correlation between the two is at its lowest level since 2015.

Correlation describes the degree to which two price movements are synchronized. High correlation means that Bitcoin is actually traded as a technology stock. When correlations fall, Bitcoin once again carries its own unique risk factors in the portfolio, not just a magnified version of equity risk. For portfolio diversification, this is the real news to watch for this week.

The next interest rate decision of the Federal Reserve's Open Market Committee is scheduled for October 28, 2026, which will help determine whether long-term pressures continue.

Why is the current U.S. dollar driving force stronger than the stock market?

Dragosch表示，他认为这一变动主要归因于美元：比特币目前受美元的影响大于受股市的影响，“至少根据我们的分析”。同一次谈话中的第二个观察结果与此相符，即比特币与黄金的相关性已达到六年高位。Dragosch称，投资者“正在同时买入比特币和黄金”。

这是分析师的观点，而非关于未来的既定事实。但可以确定的是其描述的关联：当美元而非股市成为主导驱动力时，比特币价格更多取决于利率决策和通胀数据，而非科技公司的季度财报。因此，对于个人规划而言，央行的日历日期比财报季更为重要。

实际利率与机会成本：5.28%的无风险收益对抗零息资产

比特币不支付利息，也不分红。所有回报必须来自价格上涨。安全政府债券的收益率越高，持有非生息资产的机会成本就越高，即投资者因持有非生息资产而非债券所放弃的金额。

从算术上看，差异是显而易见的。如果将10,000欧元存入为期一年的10年期德国国债（收益率3.66%），税前利息收入约为366欧元。若以5.28%的收益率存入10年期美债，则为528美元，但这还需加上可能双向波动的美元兑欧元汇率风险。比特币必须先通过价格上涨实现同等金额，才能产生超额回报。

This calculation is not a reason to oppose cryptocurrencies, but a benchmark for introducing every investment decision in the context of high interest rates. This also explains why historically periods of high real interest rates have been unfavorable for assets that lack income streams.

Bitcoin prices range from US$83,898 to US$86,796: down 32.7% from record highs

As of this writing, Bitcoin is trading at approximately US$84,900 (approximately 75,400 euros). In the past 24 hours, the price range has ranged from $83,898 to $86,796, a decline of about 2%. It has risen slightly by about 1% in the past seven days and has risen slightly less than 8% in the past 30 days. The market value is approximately US$1.71 trillion.

The price is still 32.7% away from the all-time high of US$126,080 set on October 6, 2025. The anniversary of that record is approaching, coinciding with a high interest rate level not seen in more than two decades.

German buying channels: MiCA licenses, spot purchases and ETN in brokerage accounts

German investors have two main distinct buying channels. The first is to purchase coins directly through a trading platform. Under the European Cryptographic Asset Markets Regulation (MiCA), providers need to obtain a license in the EU. Which platforms have this license and their fees can be found for an overview of the best cryptocurrency exchanges.

The second approach is through a regular brokerage account. In Europe, there are no spot ETFs for a single crypto asset because EU law requires funds to diversify their investments. It is replaced by transactional notes (ETN or ETP). Such notes track price but are legally a claim on the issuer and therefore carry issuer risk. For which products can be traded in Germany and their differences, please refer to the overview of crypto ETFs for German investors.

Holding period under Article 23 of the German Income Tax Law: interest rate path from one year to October 28

For German individual investors, Article 23 of the German Income Tax Law applies for tax purposes. Proceeds from selling crypto assets are tax-exempt after holding for more than a year. Personal income tax rates apply for one year, except for exemption limits that cover the total of all private disposal transactions.

This deadline ties taxes to the interest rate calendar. People holding positions starting in the late fall of 2025 are approaching the one-year limit, and sales shortly before that may require higher taxes, while sales a few days later may be tax-free. In turn, this deadline also locks in capital during periods when high interest rates are likely to persist. Users who want to track which positions are about to expire and when they will expire can refer to the Overview of Crypto Tax Tools and Combined Trackers.

The crypto market's calendar was largely blank ahead of the October 28 interest rate decision, which extended the period of uncertainty.

Leverage, funding rates and clearing prices when funds are expensive

High interest rates increase borrowing costs, which in turn affects leveraged positions in the crypto market. For open-end futures contracts such as perpetual contracts, funding rates ensure that the contract price anchors the spot price. This is a regular payment between buyers and sellers and often increases as the general interest rate level rises.

The clearing price is the price at which the margin is no longer sufficient to maintain a position and the position is forcibly closed. Given that the 24-hour high and low range fluctuates close to $2,900, this point is hit faster than the calm weekly balance sheet suggests. For EU retail customers, leveraged products are also subject to leverage caps, further reducing the operating space.

Custody and pledge income in a high government bond yield environment

There are two parallel models in custody. Under trusteeship by the service provider, the key is kept by the provider, which requires a license in the EU. Under self-custody, the key is held by the investor, usually on the hardware device, and assumes full responsibility for recovering the mnemonic.

High interest rates also affect earnings quotes in the crypto market. If the return on government bonds is 5.28%, the coin yield promised by the provider must be significantly higher to remain attractive. However, higher bids are rarely generated out of thin air and are usually lent out on a coin basis or deployed in an agreement. As long as the risk of default is ignored, comparing such returns with government bonds is misleading.

Bull and Bear Market Scenarios: Bitwise Model and Interest Rate Pressure

Expectations differ widely, and both sides 'views deserve to be treated fairly.

The optimistic aspect is Bitwise's valuation model. Dragosch pointed out to the media that the fair value of BTC is approximately US$197,000 and said a lot of bad news has been "priced in." If this reading holds, the current level is more a discount for macro concerns than a new equilibrium.

The cautious side is the interest rate series itself. A level unseen since 2002 keeps the risk-free benchmark permanently high and attracts capital away from investments with no sustainable return. As long as long-term yields do not yield, this headwind will still exist regardless of how the model calculates fair value. In any case, the price target is the personal opinion of the person proposing it.

Portfolio and Order Book: Things to Check Before Interest Rate Resolution

The next significant date has been determined. The Federal Reserve's Open Market Committee will meet on October 27 and 28, 2026, and announce its decision on October 28. Prior to this, the calendar was largely blank, during which time three things could be leisurely checked: whether open leveraged positions had clearing prices in the most recent intraday range; when the first positions would expire a year; and whether interest-bearing alternatives in the local currency region were actually more in line with the expected investment term.

U.S. debt and Bitcoin: The main takeaway

benchmark has been shifted. A yield of 5.28% in U.S. dollars and a yield of 3.66% in euros are the opposite of competition for every interest-free asset. Those wanting to enter new places should check in advance the buying channels and fees in the overview of the best cryptocurrency exchanges.

Decoupling changes its role in the mix. When Bitcoin no longer runs in sync with the stock market, its diversification function changes. Those who want to gain access through a brokerage account rather than a trading platform can find terms in the Overview of the Best Cryptocurrency Brokers.

October 28 is the next metronome. Before interest rate decisions, it is beneficial to focus on the clearing price and the one-year period of Article 23 of the German Income Tax Act, as these two variables change over time rather than with headlines.
