Stocks whipsawed Wednesday afternoon and briefly erased their losses before selling off again into the close after the FOMC kept interest rates unchanged in a hawkish Fed hold.  Three Fed members dissented in favor of a quarter-point rate hike, and Fed Chair Warsh said the Fed is committed to “deliver price stability.”  The 10-year T-note yield rose +4 bp to 4.64%.

Earnings results from Microsoft and Meta Platforms after Wednesday’s close will be looked at to see whether the vast spending behind the buildout of artificial intelligence can deliver adequate returns. 

The FOMC, as expected, kept the fed funds target range unchanged at 3.50% to 3.75% in a 9-3 vote, with Cleveland Fed President Beth Hammack, Minneapolis Fed President Neel Kashkari, and Dallas Fed President Lorie Logan voting for a quarter-point rate hike.

The post-FOMC statement said, "Economic activity is expanding at a solid pace despite elevated uncertainty that owes, in part, to the conflict in the Middle East," adding that "productivity growth and capital investment are strong."  Inflation remains elevated "in part reflecting supply shocks that have driven price increases in certain sectors, including energy." 

Fed Chair Warsh said, "The economy is showing impressive resilience" even with recent shocks and policymakers "will not hesitate to act" if inflation remains elevated.

Sep WTI crude oil prices (CLU26) jumped by more than +6% on Wednesday as the recent lull in hostilities came to an abrupt end after the Islamic Revolutionary Guard Corps (IRGC) said it targeted a US airbase and command center in Jordan with ballistic missiles. The IRGC also claimed to have hit and halted three tankers attempting to transit through the Strait of Hormuz. Meanwhile, the US and Saudi Arabia launched a joint attack on "Iran-aligned terrorists" in Iraq after the IRGC directed them to target US forces and Saudi energy infrastructure.

Tensions remain high in the Middle East as the US maintains its blockade of Iranian oil shipments in the Persian Gulf.  Also, diplomatic attempts to reopen the Strait of Hormuz appear to be at an impasse.  Iranian Deputy Foreign Minister Gharibabadi said Oman's proposal for a route through the Strait of Hormuz, with 50% under Iran's control and 50% under Oman's, would not address Iran's concerns and that the inbound passage and part of the outbound channel must be entirely under Iran's control.

US MBA mortgage applications fell -6.4% in the week ended July 24, with the purchase mortgage sub-index down -3.6% and the refinancing mortgage sub-index down -9.9%.  The average 30-year fixed rate mortgage rose +7 bp to an 11.5-month high of 6.76% from 6.69% the prior week.

The outlook for strong Q2 earnings, which continue this week, is a bullish factor for stocks.  The markets are awaiting results from a raft of megacap technology companies this week, including Microsoft and Meta Platforms today, and Amazon.com and Apple on Thursday.  Forecasts compiled by Bloomberg Intelligence suggest Q2 earnings may increase by +23%, close to Q1’s blowout earnings of +30%, which was more than double the +12% analysts had expected.  AI spending is expected to account for most of earnings, with AI infrastructure stocks set to contribute nearly 60% of the S&P 500's earnings-per-share growth in Q2. So far, earnings results have been positive, with 87% of the 216 S&P 500 companies that have reported Q2 earnings beating estimates, according to Bloomberg data. 

The markets are discounting a 56% chance of a +25 bp rate hike at the next FOMC meeting on September 15-16.

Overseas stock markets settled mixed on Wednesday.  The Euro Stoxx 50 closed down -0.65%.  China's Shanghai Composite rebounded from a 1-week low and closed up +0.40%.  Japan's Nikkei-225 Stock Average fell to a 2.25-month low and closed down -1.49%.

Interest Rates

September 10-year T-notes (ZNU6) on Wednesday closed down -1 tick.  The 10-year T-note yield rose +3.3 bp to 4.639%.  T-notes were under pressure from Wednesday’s +6% surge in crude oil prices, which raises inflation expectations and is hawkish for Fed policy.  Also, the FOMC's hawkish hold on interest rates weighed on T-note prices after three Fed members dissented in favor of a 25 bp rate hike, and Fed Chair Warsh said policymakers "will not hesitate to act" if inflation remains elevated. 

European government bond yields moved higher on Wednesday.  The 10-year German bund yield rose +5.6 bp to 3.160%.  The 10-year UK gilt yield rose +9.2 bp to 5.036%.

The German Jun import price index eased to 6.1% y/y from 6.8% y/y in May.

The markets are discounting a 90% chance of a +25 bp ECB rate hike at their next policy meeting on September 10.
