It's been a history-making year for Wall Street and the Federal Reserve. Earlier this month, the Dow Jones Industrial Average (DJINDICES: ^DJI), S&P 500 (SNPINDEX: ^GSPC), and Nasdaq Composite (NASDAQINDEX: ^IXIC) reached all-time highs.
Meanwhile, President Donald Trump's handpicked successor to Jerome Powell, Kevin Warsh, was officially sworn in as only the 17th chair in the Federal Reserve's history, since its inception in December 1913. Warsh has wasted little time changing the narrative at America's foremost financial institution, which holds major implications for Wall Street and investors.

There's, arguably, no issue of greater importance at the moment than inflation. With trailing 12-month inflation vaulting to a three-year high in May, the newly updated June inflation forecast from the Federal Reserve offers a good news-bad news scenario for Wall Street.
The Iran war has sent prices soaring
Although President Trump's tariffs are a lingering concern in the goods sector, the bulk of America's inflationary pressure can currently be traced to the Iran war.
Shortly after President Trump gave the green light for the U.S. military to attack Iran, the latter closed the Strait of Hormuz to commercial vessels. This action-and-reaction halted the daily transport of approximately 20 million barrels of petroleum liquids, representing a fifth of the world's demand.
BREAKING: May CPI inflation rises to 4.2%, the highest level since April 2023.

Core CPI inflation also rises to 2.9%, the highest since September 2025.
Inflation in the US is officially back above 4% and more than double the Fed's target.
Odds of Fed rate hikes are rising.
As you can imagine, removing 20% of the world's crude oil supply overnight had quite the impact on energy prices. Gas prices soared at the fastest pace in more than three decades, while diesel prices jumped by an even steeper percentage.
In three months, TTM inflation has increased from a modest 2.4% to the aforementioned three-year high of 4.2% in May. Consumers are feeling this pressure in their pocketbooks, and the central bank has taken notice.

The latest June inflation forecast is a mixed bag
However, the Federal Reserve Bank of Cleveland's proprietary Inflation Nowcasting tool offers something of a silver lining for June. This inflation forecasting tool updates daily, Monday through Friday, following the release of new economic data.
According to the Cleveland Fed (as of June 18), TTM inflation for June is expected to modestly decline to 4.01%. Crude oil prices have tapered noticeably as peace talks between the U.S. and Iran have progressed. Since energy prices have been the primary driver of inflation, lower oil prices can provide some relief to consumers.
On the other hand, Core Personal Consumption Expenditures (PCE), a favorite inflationary measure of the central bank, isn't budging. The June Core PCE estimate of 3.3% remaining flat suggests inflationary pressures are filtering into other areas of the U.S. economy beyond energy and food. This implies that above-average inflation may last considerably longer than initially expected.
Very hawkish dot plot.

Nine out of 18 officials have at least one hike this year (and six of those 9 have *multiple hikes*).
Only one person has a cut this year, and one participant (presumably Warsh) didn't submit an SEP

Even if the president and his administration are successful in ending the Iran war in the near future, the foundation has been laid for the Federal Reserve to act. The quarterly filed dot plot (officially, Summary of Economic Projections) found that nine out of 18 anonymous Federal Open Market Committee members expect higher interest rates by the end of this year.
It could be extremely difficult for a historically pricey stock market to adapt to a rate-hiking environment. An expensive stock market already has little room for error. If Trump's actions in Iran force the central bank to raise interest rates, this margin for error may completely disappear.
