Trump immediately ordered a naval blockade of the Strait of HormuzStrait of HormuzNarrow waterway between Iran and Oman carrying ~20% of global seaborne oil. A blockade would severely disrupt energy supplies.. The US Navy will block all ships to/from Iranian ports and seize vessels that paid Iran tolls (up to $2M/ship, some in yuan). CENTCOM begins enforcement today April 13 at 10:00 AM ET. Concurrent mine-clearing operations will proceed. Non-Iran-bound vessels may pass freely, but escalation risks for oil, global economy, and US-China relations are significant.
US Orders Naval Blockade of Strait of Hormuz — Ships Paying Iran Tolls to Be Seized, Enforcement Begins Today 10:00 ET
Following the collapse of peace talks in Islamabad, President Trump on April 12 ordered a US Navy Strait of HormuzStrait of HormuzNarrow waterway between Iran and Oman carrying ~20% of global seaborne oil. A blockade would severely disrupt energy supplies. naval blockade. Since hostilities began in late February, Iran had effectively closed the strait while allowing some vessels to pass for tolls of up to $2M/ship (some paid in yuan). Trump declared that "all vessels that paid illegal tolls to Iran will be searched and seized in international waters," warning that "those who paid tolls are not guaranteed safe passage." CENTCOM announced it will "impartially" enforce the blockade on ships entering/leaving Iranian ports starting today, April 13, 10:00 AM ET, with concurrent mine-clearing operations. Non-Iran-bound vessels may transit freely, but escalation with China, India, and other nations that have been paying tolls to import Iranian oil is inevitable. The blockade of a chokepoint carrying 20% of global oil shipments poses compounding risks: an oil price spike, global economic fallout, and deteriorating US-China relations.
US Consumer Sentiment Hits All-Time Low — UMich Index at 47.6, Worst in 70+ Years of Survey History
The University of Michigan's consumer sentiment index (preliminary) released April 10 plunged 11% from the prior month to 47.6, the lowest reading since the survey began in 1952. This marks a historic collapse, falling below the Biden-era inflation peak (50) and the Great Recession trough. Survey director Joanne Hsu noted that "confidence declined across all demographic groups regardless of age, income, or political affiliation." The primary drivers are anxiety over the Iran war and surging gasoline prices, with 1-year inflation expectationsInflation ExpectationsThe future inflation rate anticipated by consumers and market participants. The Fed closely monitors whether expectations remain "anchored"; a sharp rise can become a self-fulfilling prophecy. jumping a full percentage point from 3.8% to 4.8%. The same-day March CPI confirming a 21.2% gasoline price surge further eroded confidence. However, the immediate equity market impact was limited, with many analysts viewing sentiment as "a lagging indicator of behavior." The key question is whether this psychological deterioration will translate into actual consumer spending cuts.

Consumer Sentiment Index — How Psychology Drives the Economy
The Consumer Sentiment Index quantifies how ordinary consumers feel about current economic conditions and future prospects. The most historically significant and influential is the University of Michigan Consumer Sentiment Index, which has surveyed approximately 600 households by phone each month since 1952, asking about "current living conditions" and "future economic outlook" on a 5-point scale. Above 100 indicates optimism; below 50 signals severe pessimism.
The other major gauge is the Conference Board Consumer Confidence Index, which surveys about 3,000 households with a heavier emphasis on employment conditions. While the two measures correlate, the Michigan index is more sensitive to gasoline prices and inflation expectations, whereas the Conference Board index responds more to labor market shifts.
Historically, a sharp drop in consumer sentiment does not necessarily lead to recession. In June 2022, surging gasoline prices pushed the Michigan index to 50, yet the real economy remained resilient. However, prolonged pessimism risks triggering a "self-fulfilling recession" spiral: anxiety leads to spending cuts, which hurts corporate earnings, which triggers layoffs, which deepens anxiety further.
The "Two-Faced CPI" and the Market's Bet — Is the Energy Shock Transitory or Structural?
March CPI was like a coin with two faces.
The front face is shocking. Headline CPI surged +0.9% MoM and +3.3% YoY, leaping from 2.4% just a month earlier to the highest level in two years. The culprit is clear — a 21.2% gasoline price surge. The Iran war's de facto closure of the Strait of Hormuz cut off 20% of global oil shipments, pushing overall energy prices up 10.9%.
The reverse face is surprisingly mild. Core CPI (excluding food and energy) came in at +0.2% MoM and +2.6% YoY, beating estimates by 0.1pp each. "Sticky" categories like shelter, medical care, and used cars remained stable.
The market chose to believe the reverse face. Friday's S&P 500 fell just -0.11%, with no panic. The logic is straightforward — the FedFederal Reserve (Fed)The US central bank. Manages monetary policy (interest rates, QE/QT) to achieve price stability and maximum employment. Chair: Jerome Powell. focuses on core, and the energy shock is transitory, destined to fade with a ceasefire.
But this bet rests on two assumptions.
First, the ceasefire must hold. Yet weekend peace talks in Islamabad collapsed. VP Vance walked out after Iran refused to halt uranium enrichment, and Trump ordered a Hormuz Strait "blockade." With the two-week ceasefire deadline approaching, if oil prices breach $100 again, April CPI will be affected.
Second, consumer psychology must not spill into the real economy. Yet the UMich index at a historic low of 47.6 shows consumers do not view this as "transitory." The 1-year inflation expectations surge to 4.8% is particularly alarming — an "unanchoring" of inflation expectations is one of the Fed's most feared scenarios.
Scenarios for the week ahead. If Tuesday's PPI (March) shows energy-driven upside similar to CPI, the "two-faced inflation" thesis will be confirmed. Thursday's Netflix earnings will serve as a barometer for discretionary consumer spending. Above all, the fate of the ceasefire extension is the biggest variable.
The market's "core stability" scenario is rational but fragile. A macro storm alongside micro calm — which way this divergence resolves will determine the direction of Q2 markets.
