Currently, crude oil prices and bond yields are exhibiting an unprecedentedly close correlation. Fluctuations in oil prices directly drive synchronized fluctuations in bond yields and, in turn, influence stock market performance, becoming the most prominent trading characteristic in the recent market. However, this highly synchronized market movement actually harbors irrationality. The bond market has excessively anchored itself to oil price changes, overestimating the long-term inflationary impact of oil prices, leading to an excessive rise in long-term bond yields. This has resulted in a series of chain reactions affecting debt, the stock market, and other sectors being exaggerated by the market. Oil prices only have a one-off, short-term impact on inflation and are unlikely to significantly alter long-term interest rate trends. The current abnormal correlation between the two is the result of multiple factors, including fiscal policy, economic fundamentals, market pricing discrepancies, and confused expectations, further obscuring valuations and risk assessments in the current bond market. Bond yields and oil prices are currently moving in a highly synchronized manner, with a clear and intuitive correlation: rising oil prices lead to higher bond yields and falling stock markets. This month, the intraday correlation between the 10-year US Treasury yield and crude oil futures hit a record high, and this week's market performance perfectly illustrates this linkage. On Monday and Tuesday, oil prices slightly declined, and bond yields followed suit; on Wednesday, oil prices surged, and yields soared in tandem; on Thursday, both instruments continued their upward trend, rising in tandem again. However, this market consensus trading logic actually has a fatal flaw. The bond market's view of oil price fluctuations as the core pricing basis, and its excessive focus on the inflationary impact of oil prices, is essentially a trading misconception. If this judgment holds true, the current rise in bond yields has already exceeded expectations, and a series of chain reactions derived from high yields, including government debt valuations, stock market trends, and the pricing of various financial assets, have all shown significant overreaction. I. The Short-Term Impact of Oil Prices Creates a Core Contradiction with Long-Term Bond Trends From a superficial perspective, market trading behavior seems logical. Rising oil prices directly push up market inflation. The Federal Reserve, led by new Chairman Kevin Warsh, has clearly stated its policy response to inflationary fluctuations caused by oil prices. This naturally links higher oil prices to short-term interest rate hike expectations, pushing up short-term bond yields. However, the market has overlooked a crucial point: short-term interest rate fluctuations are insufficient to support a simultaneous rise in long-term bond yields. Currently, the 10-year US Treasury yield has climbed to 5.2%, reaching its highest level since the eve of the global financial crisis in June 2007—a highly irrational trend. Former European Central Bank Vice President Vitor Constio also stated bluntly that daily fluctuations in oil prices have no logical basis or value in influencing 10-year bond yields. Fundamentally, the inflationary shock from rising oil prices is one-off and temporary. On the one hand, the disruption to Persian Gulf oil supply will not last forever, and the rise in oil prices is not sustainable in the long term; on the other hand, even if oil prices remain high, it will only push up inflation once (at most twice through indirect transmission). Once oil prices stop rising, its direct effect on inflation will completely disappear. More importantly, if high oil prices continue to drag down the real economy and suppress market demand, it will actually lower the inflation level of non-oil commodities, completely offsetting the previous inflationary impact. Anomaly is that the correlation between crude oil and bonds remains high, with long-term bonds showing a much stronger correlation than short-term bonds. Even after removing short-term interest rate interference and constructing a five-year forward synthetic bond, the strong correlation between oil prices and long-term bond yields still exists, completely violating normal macroeconomic pricing logic. It's understandable that two-year short-term bonds fluctuate with oil prices, as they are highly tied to the Fed's short-term interest rate policies. Oil prices pushing up expectations of interest rate hikes naturally leads to fluctuations in short-term bonds; the current futures market has also priced in a more than 50% probability of four Fed rate hikes by the end of next year. However, short-term interest rate changes have a negligible impact on 10-year long-term bonds, and are almost negligible on 30-year long-term bonds. Unless the market believes that high interest rates will persist in the long term, there would be no such dramatic correlation as the current market. II. Market Explanations of the Multiple Core Logics Behind the Oil-Bond Linkage Regarding the unusually strong correlation between oil prices and long-term bond yields, the market has developed multiple reasonable interpretations, with no single standard answer. Each logic can explain part of the market phenomenon. First, there's the logic of fiscal pressure. High oil prices are forcing governments worldwide to implement various hedging policies, including industrial subsidies, tax breaks, and bans on crude oil exports. These policies directly exacerbate government fiscal deficits and disrupt international trade order, suppress economic growth, and reduce tax revenue. The global bond market is already deeply mired in high debt anxiety; the fiscal deterioration and weakened debt repayment capacity caused by rising oil prices force investors to demand higher bond yields to hedge against potential debt risks. Second, there's the tipping point effect of the economic cycle combined with supply shocks. This round of oil price increases is not an independent trend but occurs within an economic boom cycle driven by the expansion of the AI industry. Strong economic fundamentals allow the market to absorb high oil prices, and positive growth expectations themselves will simultaneously push up both oil prices and bond yields. The simultaneous rise in both indices after Wednesday's strong economic data is the best evidence of this. In short, the combined effect of AI-driven endogenous economic growth and the oil supply shock caused by the US-Iran situation has created an extreme oil-bond linkage rally. Secondly, there's the issue of pricing discrepancies in long-term bonds. Former Federal Reserve Vice Chairman Alan Blinder discovered the irrational pricing characteristics of the market as early as thirty years ago: the intraday price fluctuations of one-year short-term bonds were highly correlated with the implied interest rate 29 years later. However, from a rational macroeconomic perspective, a single day's market event cannot affect market interest rate trends decades later. This confirms the core issue: the market's pricing of long-term bonds is extremely irrational, and the sensitivity of long-term yields to short-term oil price and interest rate news far exceeds the reasonable pricing range. Finally, there's the ambiguity of market expectations. Former hedge fund manager and Bank of England policy committee member Sussier Wadwani pointed out that the market cannot accurately distinguish between temporary and permanent interest rate increases during a rate hike cycle. Without clear evidence that interest rates are too high, the market will habitually assume that some interest rate hikes are sustainable in the long term. This means that short-term fluctuations in oil prices and changes in interest rate expectations will directly impact the pricing of long-term bonds with maturities of several decades. Third, the interconnected market is essentially a resonance, not a causal relationship, as history has already proven . Many senior central bank officials have maintained a rational perspective on the current oil-bond linkage. Constio stated bluntly that the high intraday correlation observed by the market is essentially a resonance and coincidence, not a causal relationship where oil prices unilaterally drive bond yields. He also acknowledged that the current rise in 10-year bond yields has some justification; from a long-term macroeconomic perspective, real interest rates, after adjusting for inflation, need to remain at a relatively high level. Historically, the extremely high correlation between oil prices and bond yields has never been an exception, and the core logic behind each instance of this linkage has never been simply driven by oil prices. During the first Gulf War in 1990-1991, Gulf oil trade was disrupted, and market risk sentiment resonated, increasing the correlation between oil and bonds. In 2010, concerns about global economic growth intensified, and third-party macroeconomic factors simultaneously suppressed both the bond market and oil prices. The Eurozone crisis in 2012, the deep recession in the global oil industry in 2016, and the COVID-19 pandemic's impact on global commodities in 2020—each cycle's strong correlation between oil and bonds reflects a unidirectional trend driven by the macroeconomic environment, rather than a causal transmission of a single variable. This also illustrates that there is no fixed scientific law governing the correlation between oil and bonds, and the signals in the bond market are inherently contradictory and misleading. IV. Market Summary Based on different interpretations of market logic, the current high bond yields will present two completely opposite investment value judgments. If the current high yields are the result of the market overestimating the short-term impact of oil prices and irrational trading, then bond assets at this stage have extremely high allocation attractiveness. If the rising yields are essentially a reflection of the expansion of government debt and the increasing risk of debt repayment, then the current yield level simply cannot cover the potential market risks. In fact, the unusual correlation between oil and bonds in this round is not driven by a single logic, but rather is the result of the combined effect of all the theories mentioned above and multiple factors. From a practical investment perspective, I am optimistic about the allocation value of US Treasuries, especially UK government bonds, with the core logic being to use them as a hedging tool to mitigate the risks of a reversal in the AI sector and significant stock market volatility. However, at the same time, like all investors in the market, I remain highly vigilant about the three core risks: the continuously rising debt pressure in the US, the Federal Reserve's lagging policy response to rapid economic growth, and the inflationary uncertainty brought about by the continued volatility of oil prices.
