Why the Mexican Peso Lost Value Against the Dollar on July 13 (Super Simple Explanation)

What Happened in the World?

Imagine two big countries, the United States and Iran, had some fights near a very important narrow water path called the Strait of Hormuz (a chokepoint where lots of oil ships travel). Because of these attacks, people who trade money got scared.

• The market (a giant playground where people buy and sell currencies) became nervous.
• The Mexican peso started to lose ground against the US dollar this Monday, July 13.
• Things got more wobbly when President Donald Trump said something new: the US will charge a fee (like a toll) for ships to pass safely through the Strait of Hormuz.
• Trump told Fox News: “We will become the guardian of the Strait (…) And we should be compensated for that.” That means the US wants to be paid for keeping the path safe.

Callout: When big countries argue and leaders make surprising money-related statements, investors can get jittery, and coins like the peso may become a little less valuable compared to the dollar.

How the Peso‑to‑Dollar Price Looks Today

We use something called the exchange rate (that’s just how many pesos you need to get one dollar). Here’s the simple picture from Bloomberg (a company that reports money news):

• The peso became 0.17% weaker (a tiny bit less valuable) against the dollar.
• The exchange rate is now 17.50 pesos per 1 dollar.
• That is 3 cents more than the closing price on Friday, July 10. (So last Friday it was about 17.47 pesos per dollar, and now it’s 17.50).

Why Did This Happen? (Step‑by‑Step)

1. The US and Iran had attacks in the Middle East.
2. Money traders got worried about safety and oil supply.
3. Trump announced a possible toll for the Strait of Hormuz.
4. Investors looked at Mexico and thought it might be a bit riskier, so they liked dollars more.
5. The peso slipped a little in value.

What Smart Analysts Say

Felipe Mendoza, a market analyst at EBC Financial Group, explained it in plain words:

• For the rest of the day, we don’t expect any sudden crazy moves because the economic calendar is quiet.
• The peso’s direction will depend on how the market reads Mexico’s ability to pay its bills (fiscal viability) while facing requests from the US in the T‑MEC (that’s the trade agreement between Mexico, the US, and Canada, also called USMCA).

Callout: Key Idea: No big surprises are expected today from regular economic reports, but Mexico’s money health versus US trade demands is what traders will watch.

Going to the Bank? Here Are the Prices

Banamex (a big Mexican bank) told us what you’d get at their counters (ventanillas) this Monday session:

• Selling price: They sell 1 dollar for 17.95 pesos (if you buy dollars from them).
• Buying price: They buy 1 dollar for 16.98 pesos (if you sell your dollars to them).

(That small difference is how the bank makes a little profit, like a lemonade stand charging different prices to buy lemons and sell lemonade.)

Other Money Facts: Bonds and Other Countries

In the world of loans to governments (called bonds), here are the numbers:

• The US government’s 10‑year loan (bond) gives a return of 4.60%.
• The Mexican government’s 10‑year bond stays at 9.03% (higher because Mexico is seen as a bit riskier, like a higher allowance for a riskier chore).

Also, the peso wasn’t the only money that lost value against the dollar. Others that became weaker today:

• Israeli shekel: lost 0.51%
• Indian rupee: lost 0.31%
• Indonesian rupiah: lost 0.28%
• Japanese yen: lost 0.27%
• South African rand: lost 0.20%

Summary

On Monday, July 13, the Mexican peso weakened a bit (0.17%) to 17.50 per dollar because markets were nervous over US‑Iran attacks and Trump’s plan to charge a fee for the Strait of Hormuz. Analyst Felipe Mendoza says no disruptive moves are expected for the rest of the day, but Mexico’s fiscal stance amid US trade demands (T‑MEC) will guide the peso. Bank rates at Banamex: sell at 17.95, buy at 16.98. US 10‑year bond yield is 4.60%, Mexico 10‑year is 9.03%. Other currencies also fell. This information comes from Valeria López and Bloomberg.
