What Is Intermarket Analysis: How Long Do Iran's Dollar, Gold, Stocks and Housing Take to React?

Learn what intermarket analysis means, why global gold usually reacts to a shock before the dollar, the dollar before the Tehran bourse, and the bourse before housing, illustrated with a real, dated example from Iran's markets in the week of August 19 to 22, 2026.

What you will learn in this lesson

In this lesson you will learn what "intermarket analysis" means, why the dollar, gold, the Tehran bourse and housing react to the same shock at different speeds, and you will see that order illustrated with a real, dated example from a recent week in Iran's markets.

Definitions

Intermarket analysis means looking at several asset markets, such as currency, gold, stocks and housing, together rather than in isolation, because a piece of news or an economic shock usually enters through one market and spreads to the others with a time lag.

Lead-lag means that one market reacts to the same news sooner than another; the "leading" market moves first, and the "lagging" market follows with a delay.

Liquidity means how quickly and easily an asset can be bought or sold near its market price; the more liquid a market is, the sooner it usually adjusts its price to fresh news.

Parallel markets in Iran refers to the dollar, gold and coin, the Tehran bourse, and housing: the four channels through which household liquidity and savings move.

Mechanism: why the reactions are not simultaneous

The order of reaction is not random; it comes from the nature of each market itself:

  • Global gold is priced continuously, almost around the clock, on world exchanges, and global arbitrage aligns it with fresh news almost instantly.
  • Tehran's free-market dollar and the gold coin, following the chain described in the lesson "From the Federal Reserve to the Toman," are fed by the global ounce price and the dollar rate; but because this is not a single, always-accessible centralized market, their reaction is usually one to two days slower than global gold's.
  • The Tehran bourse lists thousands of symbols, each with its own daily price band and limited trading hours; fully digesting a piece of news across the whole index takes several trading sessions, not one hour.
  • Housing is the least liquid parallel market; prices are set through appraisal and negotiation, weekly transaction volumes are limited, and as shown in the lesson "The Boom and Bust Cycle of Housing," an economic shock's reflection in housing prices takes months.

A worked example: one real week in Iran's markets

On Wednesday, August 19, 2026 (28 Mordad 1405), the United Arab Emirates announced the suspension of trade and financial ties with Iran. The reaction of each market to this single piece of news shows the lead-lag order clearly:

  • That same day, the global gold ounce set a fresh record: the fastest reaction, in the most liquid market.
  • That same day, Tehran's free-market dollar and the gold coin stayed almost unchanged; per Sahmino's own market record, TEDPIX, the Tehran Stock Exchange's benchmark index, rose only about 0.08 percent that day, effectively flat.
  • The next day, Thursday, August 20 (29 Mordad), on a fresh US sanctions threat, the global gold ounce crossed 4,500 dollars, and this time the dollar, gold and the Tehran coin all rose together with it: Iran's domestic FX chain caught up with the global shock one day later.
  • The Tehran bourse was closed Thursday and Friday (29 and 30 Mordad). On Saturday, August 22 (31 Mordad), its first trading session after three days, TEDPIX jumped nearly 1.8 percent to break through the 6 million point mark for the first time, reaching about 6,061,000 points, on the very same day the United States and the UAE both ratcheted up pressure on Iran together.

Here is the key point: the bourse did not fall under greater political pressure, it rose. That is because a large share of the benchmark index's weight belongs to export-oriented, "dollarized" companies, which expect higher rial profits when the dollar gets more expensive, the same distinction explained in the lesson "Dollar Shares and Rial Shares."

In Iran's market

In Iran's market, these four parallel markets react to each other at different speeds:

  • Dollar and gold/coin: their relationship is nearly formulaic; domestic gold and coin prices are built from the global ounce multiplied by the dollar rate, as shown in the lesson "The Gold Price Formula in Iran," so when the dollar moves, gold and coin usually follow the same day or the next.
  • Tehran bourse: its reaction is not uniform; export-oriented, "dollarized" symbols often move in the same direction as the dollar, while "rial" symbols, whose costs and revenue are domestic, can be hurt by a dollar jump. The benchmark index is a weighted average of these two different reactions, not one uniform reaction across all symbols.
  • Housing: the slowest link. As shown in the lesson "The Boom and Bust Cycle of Housing," during one jump period the best real-estate fund on the bourse returned roughly a third of what Tehran housing prices gained; housing both starts later and takes longer to reach its final price.

Common mistakes

  • Assuming the bourse always falls against the dollar and gold; this very week's example showed that when the index's composition is dollar-heavy, the opposite of that assumption can happen.
  • Ignoring that the intermarket relationship has no fixed direction; sometimes it moves together, sometimes inversely, depending on the type of shock (political, inflationary, global interest rates).
  • Seeing a pattern once and treating it as a permanent rule; the lead-lag order is a general tendency, not a fixed formula for every piece of news.
  • Comparing markets' speeds directly without accounting for liquidity; housing should never be judged against the speed of the bourse or the dollar.

Summary

Intermarket analysis means tracking one piece of news across four parallel markets, each with its own order and time lag: global gold usually reacts first, the domestic dollar and coin one to two days later, the Tehran bourse over several trading sessions, and housing over a span of months. In the previous lesson, "The Steel and Materials Chain," you saw how a single input reaches housing prices with a delay; in this lesson you saw where the housing market itself, alongside the other three parallel markets, stands on this same timeline.

For a fuller look at the chain from the dollar to the coin, see the lesson "From the Federal Reserve to the Toman," and for the exact gold price formula, see "The Gold Price Formula in Iran." For the difference between dollar and rial stocks' reactions, read "Dollar Shares and Rial Shares," and for housing's slow cycle, read "The Boom and Bust Cycle of Housing."
