On 8 October 2026 Federal Reserve Governor Christopher Waller gave a speech titled "The Signaling Value of the Summary of Economic Projections".
In September the FOMC raised the policy rate 25 basis points to 3.75 to 4 percent, ending nine months of holding steady.
He said August core PCE inflation was 0.25 percent for the month and 3 percent over 12 months.
In the Summary of Economic Projections, 16 of 18 participants expected at least one more hike this year.
Waller named the Middle East conflict and high energy prices, the AI buildout and trade-related tariffs as upward pressures on prices.
Policy rate:
3.75 to 4 percent
September hike:
25 basis points
SEP participants expecting another hike:
16 of 18
August core PCE, 12-month:
3 percent
Why it matters for exams: Policy-rate moves of the US Federal Reserve move global capital flows and the rupee, so exams ask about FOMC, basis points and PCE.

On 8 October 2026 the US Treasury's Office of Foreign Assets Control (OFAC) sanctioned Iran's remaining shadow fleet of ageing tankers and the companies behind it.
The action was taken under Executive Order 13902, which targets Iran's petroleum sector and other key sectors of its economy.
It designated 17 vessels carrying Iranian crude oil, petroleum and petrochemical products.
It is part of Operation Economic Outcast, which Secretary Scott Bessent announced on 24 August 2026.
OFAC also removed two vessels, HAKUNA MATATA and PINOCCHIO, from the SDN List after they were sold to non-sanctioned operators.

Background
The Federal Reserve is the central bank of the United States, created by the Federal Reserve Act.
The Federal Reserve System has two parts: the Board of Governors, a federal agency located in Washington, D.C., and 12 Federal Reserve Banks around the nation, which together have 24 Branches.
The Board is run by 7 members, or "governors", serving staggered 14-year terms, who are nominated by the President of the United States and confirmed by the U.S. Senate.
The Federal Open Market Committee, or FOMC, is a 12-person group that sets monetary policy at meetings held at least 8 times each year; its 12 voting members are the 7 governors, the president of the Federal Reserve Bank of New York, and 4 of the remaining 11 Reserve Bank presidents on one-year rotating terms.
The Federal Reserve Board is the issuing authority for Federal Reserve notes; the Federal Reserve Banks distribute, receive, and process those notes.
More than 99 percent of all U.S. currency in circulation is in the form of Federal Reserve notes.
The notes themselves are printed to the Board's order by the Treasury's Bureau of Engraving and Printing, whose facilities are in Washington, D.C., and Fort Worth, Texas.
Coins are separate: as the issuing authority for coins, the United States Mint determines annual coin production and moves coin from its production facilities in Philadelphia and Denver.
Capital:
Washington, D.C.
Issuing authority for notes:
The Federal Reserve Board
Reserve Banks and Branches:
12 Federal Reserve Banks, 24 Branches
Board of Governors:
7 members, staggered 14-year terms
FOMC voting members:
12, meeting at least 8 times each year
Share of currency as Federal Reserve notes:
More than 99 percent
Cash offices and institutions served:
28 Federal Reserve Bank cash offices serving approximately 8,400 banks, savings and loans, and credit unions
System began operations:
1914
Why it matters for exams: A country profile is almost always asked through its capital, its currency and the body that issues that currency, and the Federal Reserve's two-part structure is a standard comparison with the Reserve Bank of India.

In plain words
FOMC Federal Open Market Committee — The 12-person committee of Federal Reserve officials that decides the stance of United States monetary policy.
BEP Bureau of Engraving and Printing — The United States Treasury body that prints Federal Reserve notes to the order placed by the Federal Reserve Board.
Background
The Congress of the United States is the legislative branch and has two chambers, the Senate and the House of Representatives; the first Article of the Constitution establishes their structure and powers.
The Senate clause as drafted reads: "The Senate of the United States shall be composed of two Senators from each State, chosen by the Legislature thereof, for six Years."
State legislatures continued to elect senators until adoption of the Seventeenth Amendment to the Constitution, which provided for popular election of senators, in 1913.
The Constitutional Convention approved two senators per state by unanimous vote, and adopted a six-year, three-class Senate so that one third of the members go out every second year.
A Senator must have attained the "Age of thirty Years" and have been "nine Years a Citizen of the United States", and must be an inhabitant of the State for which he shall be chosen.
"The Vice President of the United States shall be President of the Senate, but shall have no Vote unless they be equally divided"; the Senate also chooses a president pro tempore to preside in the Vice President's absence.
Treaties are made by and with the "Advice and Consent of the Senate", provided "two thirds of the Senators present concur"; the same advice and consent governs the appointment of Ambassadors, other public Ministers and Consuls, and Judges of the supreme Court.
In the House the number of voting representatives is fixed by law at no more than 435, proportionally representing the population of the 50 states, and each representative is elected to a two-year term; a representative must be at least 25 years old and a United States citizen for at least seven years.
Besides the voting members there are five delegates and a resident commissioner, who hold the same powers except that they may not vote when the House meets as the House of Representatives; the arrangement of a population-based House with an equal-state Senate is called The Great Compromise.

Background
The Mississippi River is the second longest river in North America and flows from its source at Lake Itasca through the centre of the continental United States.
The Missouri River, a tributary of the Mississippi River, is about 100 miles longer than the Mississippi's own main stem.
Compared with other world rivers, the Mississippi-Missouri combination ranks fourth in length at 3,710 miles/5,970km, after the Nile at 4,160 miles/6,693km, the Amazon at 4,000 miles/6,436km and the Yangtze at 3,964 miles/6,378km.
At Lake Itasca the river is between 20 and 30 feet wide, the narrowest stretch for its entire length; the widest part is at Lake Winnibigoshish, where it is wider than 11 miles, and the widest navigable section is Lake Pepin.
The Mississippi watershed drains about 3.2 million square kilometers (1.2 million square miles), including all or parts of 31 states and two Canadian provinces, about 40% of the continental United States.
That watershed is the fourth largest in the world, extending from the Allegheny Mountains in the east to the Rocky Mountains in the west.
At least 260 species of fish, 25% of all fish species in North America, live in the Mississippi River, and sixty percent of all North American birds (326 species) use the Mississippi River Basin as their migratory flyway.
Barges and their tows move approximately 175 million tons of freight each year on the upper Mississippi through a system of 29 locks and dams.
