The Rate Game

Every time the US Federal Reserve moves its interest rate — even by a quarter point — it sets off a chain reaction that eventually touches everything from US mortgages to the dollar-peso exchange rate. It's worth understanding that chain, because once you see it, Fed decisions stop looking like isolated headlines and start looking like the first domino in a very long row.

Step 1: the dollar

When the Fed hikes rates, holding dollars becomes more attractive — you get paid more to park them. That pulls money toward dollar-denominated assets from around the world, and the dollar tends to strengthen broadly (the well-known DXY index rises). When the Fed cuts, the opposite happens: the dollar loses some of its relative appeal.

Step 2: bonds and global rates

The Fed's rate is, in practice, the "floor" that rates across the developed world get built on top of. If the Fed hikes, US Treasury yields (especially short-term ones) rise almost immediately, and that pushes rates higher in other countries too — nobody wants to lend money cheaper than the US if they don't have to.

Step 3: emerging markets (and Mexico)

This is where the peso comes in. When the dollar strengthens and US rates rise, some of the money that was sitting in emerging markets (chasing better yields) heads back home to the US, where it's now also getting paid well with less risk. That can weaken the peso and other emerging-market currencies. When the Fed starts cutting, the flow tends to reverse — money goes "shopping" for yield again, and emerging markets usually benefit.

Why this matters to you

You don't need to predict what the Fed will do — nobody does with certainty, not even the pros. But you can understand the pattern: "hawkish" decisions (tougher, more hikes) tend to strengthen the dollar and pressure the peso; "dovish" decisions (softer, fewer hikes or cuts) tend to do the opposite. Every Fed meeting (roughly every 6 weeks) is a moment worth paying a little closer attention to — and on Risk On we flag those dates for exactly that reason.
