U.S. 10-year Treasury yields pushed above 5% again in mid-September, reviving a level that has repeatedly unsettled risk assets and tightening the financial backdrop for Bitcoin and other cryptocurrencies. The benchmark yield briefly reached 5.014% intraday on Sept. 14 before ending near 4.947%, then extended the move to 5.04% on Tuesday, according to market figures cited in the analysis.
The advance ended a run of more than 700 trading days in which the 10-year yield had remained below 5% after the October 2023 spike. The level has become a closely watched dividing line: historical periods below 5% have generally ended either with a relatively quick return above it, within five to 10 months, or with yields staying under the threshold for more than 1,000 trading days.
This time, the move came with a steeper Treasury curve rather than a uniform rise in borrowing costs. The 30-year yield touched 5.38% intraday and settled at 5.328%, while the two-year yield slipped to 4.628%. That pattern, known as bear steepening, occurs when long-term yields climb faster than short-term yields. It can reflect concern that inflation, government borrowing or the term premium — the additional compensation bondholders demand for holding long-dated debt — will remain elevated.
The 10-year yield began the year around 4.15%, leaving it roughly 85 basis points higher year to date. A basis point equals one-hundredth of a percentage point.
Oil shock and central-bank expectations drive long-end pressure
The yield surge coincided with a sharp jump in oil prices after Saudi Arabia’s East–West oil pipeline was shut following an attack. The event was described in the analysis as putting supply equivalent to roughly 4% of global oil output at risk. Brent crude briefly rose above $109 a barrel.
Energy prices can feed into inflation directly through fuel costs and indirectly through transport, production and consumer prices. The immediate question for bond markets is whether the oil spike fades with a restoration of supply or becomes prolonged enough to lift underlying inflation.
U.S. core inflation for August stood at 3.4%, according to the figures in the article. CME FedWatch data cited by the analysis put the implied probability of a September Federal Reserve rate increase above 90%, with the expected federal funds target range at 3.50% to 3.75%.
The European Central Bank had raised rates the previous week, while the Bank of Japan was expected to make a policy decision on Friday. Simultaneous tightening or reduced accommodation by major central banks can leave global bond markets competing for a more limited pool of capital, particularly when governments and companies are issuing large amounts of debt.
A doubling of the U.S. Treasury’s bond-buyback operation to $6 billion from $3 billion did little to halt the climb in yields. Buybacks can improve liquidity in older Treasury securities, but the market’s response suggested that concerns over inflation, supply and long-term financing conditions were outweighing a short-term liquidity measure.
The analysis also pointed to heavy borrowing associated with data-center construction and technology infrastructure as another source of competition for capital alongside federal debt issuance. Such spending requires major corporate financing, which can add to upward pressure on long-term borrowing costs when bond supply is already substantial.
Bitcoin falls below its 50-week average
Bitcoin fell to $76,000 during the latest move in yields, according to the article, dropping below its 50-week moving average near $77,430. A moving average tracks an asset’s average price over a set period and is often used by technical traders to identify potential support or resistance levels.
The break below that level places the cryptocurrency market in a more fragile position if Treasury yields remain high. Higher yields raise the return available from U.S. government debt, while also increasing financing costs across the economy. Assets without cash flows, including Bitcoin, can face pressure when traders reassess how much risk they are willing to hold against elevated returns in bonds.
The relationship is not mechanical. Bitcoin’s price is influenced by cryptocurrency-specific flows, leverage, regulation and market positioning as well as macroeconomic conditions. Yet the timing of the selloff shows how quickly digital assets can react when longer-term U.S. borrowing rates move toward a level last sustained before major shifts in market expectations.
Previous 5% breaks produced early equity drawdowns
The historical record outlined in the analysis offers a mixed picture for equities after a sustained move above 5%, though each of the three detailed cases included an initial decline in the S&P 500 before a recovery or stabilization.
In 1966, the 10-year Treasury yield averaged 5.02% in July and 5.22% in August. The S&P 500 had already fallen about 9% from its February peak of 94.06 before the July yield break. It continued lower until Oct. 7, bottoming at 73.20 and standing 22.18% below the February high.
The subsequent rebound was swift. The index rose to 80.99 in November, reached 84.45 by January 1967 and regained its February peak by May 4. Measured from the July 1966 yield break, though, the S&P 500 was down 1.6% six months later.
The 2006 episode was more favorable for stocks after an early setback. The 10-year yield averaged 4.99% in April and 5.11% in May, eventually reaching about 5.25% in June. The S&P 500 dropped roughly 7% to 8% from May through mid-June, then recovered as yields peaked and began to decline. Six months after April, the index was up 4.7%; measured from May, it was up 7.6% by November.
In October 2023, the 10-year yield briefly exceeded 5%, reaching 5.02% intraday between Oct. 19 and Oct. 23. The S&P 500 bottomed six trading days after the break, falling to 4,117 on Oct. 27, about 4% below its Oct. 19 level. Over the following six months, it rose from 4,258.98 in October 2023 to 5,095.46 in April 2024, a gain of 19.6%.
Those examples do not establish a dependable market rule. They do show that the first reaction to a 5% Treasury yield break has often been a period of stress, while more durable equity recoveries emerged after yields stopped rising and began to retreat.
Oil, policy and earnings now set the test
The next phase depends heavily on whether the oil-driven inflation impulse proves temporary. A meaningful retreat in Brent prices would reduce pressure on inflation expectations and would more closely resemble the 2023 setup, when Treasury yields peaked soon after crossing 5%.
Persistent energy strength that spills into core inflation would create a more difficult environment, closer to the conditions associated with the 1966 example. That could reinforce expectations for restrictive central-bank policy and keep longer-dated yields elevated.
Corporate earnings are the third variable highlighted in the analysis. Continued earnings growth could help equities absorb higher discount rates, while weakening profits would leave markets with less support as financing costs rise.
For cryptocurrency traders, the immediate technical focus is Bitcoin’s ability to regain or hold around its 50-week moving average. A sustained move below that area could encourage further defensive positioning, particularly if the 10-year yield remains above 5% and oil prices keep inflation concerns alive. Treasury yields easing back below that threshold, alongside calmer energy markets, would remove one of the strongest macroeconomic pressures currently bearing on digital assets.
