Wall Street issues inflation warnings. From the bond market to senior management, signs are growing that the US-Israeli strikes on Iran may reignite price pressures that the Federal Reserve has tried to curb for years – with major implications for interest rates, risk assets and the cryptocurrency market.
The question now is whether the oil shock from Iran will become the factor that derails the rate cut schedule that Wall Street is counting on.
The Treasury market is wasting no time in pricing in the threat. Yields on 10-year bonds rose 10 basis points to 4.03% on Monday – the biggest daily increase since October – as oil prices rose more than 6% following a near-complete shutdown of tanker traffic through the Strait of Hormuz.
The expectation of a tax cut collapsed at the same time. Traders are currently pricing the Fed’s first cut in September as the earliest date, with bets almost gone on a third cut in 2026. Just weeks ago, the market was much more optimistic about the easing cycle.
The bond market makes the message clear: the risk of inflation is back, and the Fed’s hands may be tied.
Two of the most influential figures in the US financial sector confirmed that message on Monday.
Former US Treasury Secretary Janet Yellen warned from The conflict with Iran is putting the Federal Reserve “more on hold,” making policymakers more reluctant to cut rates. Speaking at S&P Global’s TPM26 shipping conference, Yellen noted that inflation is already running at about 3% — a full percentage point above the Fed’s target — with Trump’s tariffs contributing about half a point to that rate.
She expressed her greatest psychological concern. Yellen said the Fed should be afraid that market participants will conclude: “Yes, they brought it down to 3%, but they are not serious about getting to 2%.” If this impression takes hold, it could shut down expectations of permanently high inflation – a nightmare scenario for centralists.
JPMorgan CEO Jamie Dimon took a similar tone, Pointing This inflation may become the “unwelcome guest” of the US economy. Although he acknowledged that the short-term conflict would have a limited impact on inflation, he warned that a long campaign would be completely different.
If inflation becomes more persistent than expected, all investment groups will feel the impact.
For stocks, higher interest rates for a longer period reduce valuations, especially for growth and technology stocks that are affected by discount rates. Monday’s session saw a glimpse of that: The S&P 500 index fell more than 1% during trading before stabilizing again, while defensive sectors such as energy and defense outperformed, and aviation stocks fell sharply.
The picture looks more complex for cryptocurrencies. Bitcoin rose 5.7% to $69,424 on Monday, even as bonds fell — with some interpreting it as a move toward hard assets amid geopolitical uncertainty and inflation fears. Gold’s rise above $5,300 reinforced this narrative.
However, a continued period of high interest rates will challenge the upward trajectory of cryptocurrencies. The bear market of 2022 showed how digital assets can bounce back aggressively when liquidity tightens and the Fed turns hawkish. If the hope of cutting interest rates continues to fade, the appetite for risk in cryptocurrencies could face wind in the coming months.
He emphasized that Wall Street is far from unanimous on the disaster scenario.
Morgan Stanley strategists led by Mike Wilson said that the conflict in the Middle East is unlikely to erase their bullish view on US stocks, as long as oil prices do not jump sharply and stay there. J&P Morgan’s equity strategy team described the escalation as a potential buying opportunity, noting that fundamentals remain positive.
Veteran strategist Louis Navalier went further, predicting that military moves would eventually remove key uncertainties and trigger a wave of relief once pro-Western leadership emerges in Iran and resumes crude oil exports, he wrote at InvestorPlace.
In its report, the Atlantic Council emphasized this moderate tone, affirming that the global energy infrastructure remains healthy, that the fundamentals of supplies before the conflict were healthy, and the real variable is the duration of the crisis, not the strikes themselves.
All forecasts ultimately agree on one variable: how long the Strait of Hormuz will remain closed.
A solution in a few days will probably limit the inflationary impact to a temporary increase in energy prices – painful but manageable. If the disruption continues for weeks, it risks interfering with the summer gasoline transition period, rising core inflation and tariff-driven price pressures to create a combination that will force the Fed to maintain restrictive policies until 2026.
Cryptocurrency investors consider the geopolitical agenda as important as any indicator in the chain. Bitcoin may be gaining today on safe-haven flows, but if Yellen and Dimon’s predictions about the path of inflation are true, the road could be much harder before it gets easier.
