Oil does not automatically produce a lasting inflation shock. The crucial question is how long the disruption lasts and whether higher energy prices feed into wages, services and inflation expectations. For now, markets are pricing greater uncertainty rather than assuming the shock will quickly disappear.

Bond yields are turning an energy shock into a valuation problem

Long-term bond yields have remained elevated because investors are weighing several risks at the same time: renewed inflation, heavy government borrowing, future debt supply and the additional compensation demanded for holding longer-maturity bonds. The 30-year Treasury yield reached its highest level since 2007 during the recent selloff, according to Reuters.

That matters for equities because bond yields are a core input into valuation models. When the risk-free rate rises, the distant earnings of high-growth companies become less valuable today. Technology and semiconductor shares are therefore particularly vulnerable, especially when investors are already questioning the cost and scale of AI-related investment.

The market reaction has reflected that exposure. In one recent session, the Nasdaq fell 1.33%, compared with declines of 0.69% for the S&P 500 and 0.22% for the Dow.

Treasury buybacks offered liquidity, not a full solution

The U.S. Treasury’s decision to at least double buybacks of longer-dated securities to $4 billion per operation initially pushed yields lower and weakened the dollar. The measure can improve liquidity by removing older, less-traded bonds from the market, but it does not eliminate the underlying concerns about inflation or the scale of government borrowing.

That limitation became clear when bond-market relief faded. The 30-year Treasury yield later rose to 5.247%, after falling to 5.1765% following the announcement, as investors questioned whether the programme could provide lasting support.

In practical terms, the buybacks may smooth market functioning without changing the broader supply-and-demand forces that determine long-term borrowing costs. That is why equities remained vulnerable even after the Treasury intervention.

Why the selloff is spreading globally

The weakness has not been confined to U.S. technology stocks. European shares declined in the broader risk-off move, while several Asian markets were heading for weekly losses as oil prices rose and global bond-market stress persisted.

That breadth is important. It suggests a macro repricing rather than a simple rotation away from one sector. Higher yields raise financing costs internationally, while oil-importing economies face pressure on trade balances, consumers and corporate profitability.

Currency moves also complicate the usual safe-haven narrative. After the Treasury announcement, the dollar index fell 0.84% to 98.80 while the euro rose 0.88% to $1.1676. Bitcoin also rose sharply as risk assets rebounded after the initial bond-market relief. These moves indicate that investors were not responding with an uncomplicated rush into traditional U.S. safe assets; concerns about U.S. fiscal and inflation risks were part of the repricing.

What this means for Federal Reserve policy

The oil shock makes a near-term easing pivot more difficult if it begins to lift broader inflation expectations. Reuters reported that several Federal Reserve policymakers had been prepared to raise rates at the July meeting, while headline and core PCE inflation were expected to remain above 3% in July.

That leaves policymakers facing a difficult trade-off. If they respond to the oil shock too quickly, they risk allowing inflation expectations to become less anchored. If they keep policy restrictive while growth weakens, they may deepen the pressure on households, businesses and equity valuations.

The most likely market implication while the Hormuz disruption continues is greater volatility and a higher-for-longer bias in long-term yields—not necessarily an immediate rate increase, but less confidence that cuts are imminent.

The next market tests

Three developments could determine whether the selloff deepens or stabilizes:

1. Diplomacy and shipping: A credible de-escalation that restores traffic through the strait would remove part of the oil risk premium. Continued deadlock would keep energy prices and inflation expectations exposed to further shocks.
2. Core PCE inflation: The data will help show whether higher oil prices are remaining a temporary headline shock or becoming a broader inflation problem.
3. Nvidia’s earnings and Jackson Hole: Nvidia’s results will test whether AI-related earnings growth can offset higher discount rates, while the Federal Reserve’s Jackson Hole symposium is expected to provide clues about how policymakers view growth, inflation and rate risks.

The outlook: fragile, but not predetermined

The market is not simply reacting to higher oil prices. It is repricing the interaction between energy disruption, inflation, government debt and expensive growth stocks. That is why a strong earnings season alone may not be enough to restore the earlier rally if long-term yields continue climbing.

A durable recovery would probably require at least one of three changes: credible progress toward reopening shipping routes, softer underlying inflation that offsets the energy shock, or earnings that materially exceed expectations—particularly from major AI beneficiaries. Until then, the combination of elevated oil and bond yields leaves global equities vulnerable to further headline-driven swings.
