Happy Monday — let's get the week going!

On Friday the drama lived in bond volatility: MOVE at 104, VIX flat. Today that index cools to 96 — down 8.6 points, more than twice its normal daily move — and the dollar still opens the week 11 centavos above the prior close, at 17.7888, just 3 centavos from its ten-day rolling ceiling of 17.8147.

The bond calms down and the currency doesn't get the memo

Here's my read, straight up: easing Treasury vol is no relief for the peso, because the level of the yield kept climbing. The 10Y grinds to 5.21% (+0.48%) without last week's spasm.

A bond repricing higher in silence dulls the emerging-market carry just as much as one spiking on panic. The spread over Banxico now sits at 2.62pp, and with the US long end here that premium buys less every day.

Don't run the catastrophe read: the VIX at 16.06 and realized peso vol at 7.58% keep the thermometer in caution mode. This is sustained pressure, guard up, without a stampede.

A bill comes due, and the line moves

Time to settle up: the pro-peso call I opened on September 21 was invalidated today — USD/MXN ran +3.26% over five business days. It's the second time this month I've underweighted how hard the rising yield drags on the currency, and the message is getting hard to ignore.

On Friday I drew the line at 17.29 to drop the dollar bias. The pair never glanced at it, opening today at 17.79, further than ever from that floor. I lift the mark to 17.60 — a close below would flip my read to neutral — and I hold the dollar bias while the peso trades pinned to its top.

Positioning tells another story. As of September 22, Chicago speculators were still net long the peso by 75,167 contracts, though they trimmed 12,615 on the week. That's Tuesday's data, not today's flow, but it paints a market long the peso while spot runs the other way.

What moves you lands Wednesday

Risk On drops from 53 to 43 and enters DEFENSIVE: the peso sub-index sinks to 8 out of 100 and pulls the composite down on its own.

What moves the week isn't on today's screen: Wednesday's PCE (6:30 CDMX) and Friday's payrolls hand the 10Y its next excuse. With the 2s10s curve at +0.31pp — positive but flat — a hot inflation print pushes the long end and squeezes EM harder.

The level to watch is 17.8147: a close above leaves the peso with no ceiling nearby.

— See you tomorrow for Tuesday's view.

— What the index means

The Risk On index sums up global risk appetite — with a Mexico focus — in a single 0–100 number. Depending on where it lands, the day falls into one of these four bands:

0–32
Risk-off
Fear in control: money runs to safety (dollar, gold, Treasuries). Usually a weak peso and markets selling off.
33–49
Defensive
Caution: not panic, but the market eases off the gas. A time to protect more than to reach for risk.
50–67
Constructive
Healthy appetite: a selective willingness to take risk. The peso and risk assets find support.
68–100
Risk-on
Full appetite: the market buys risk with confidence. A favorable backdrop for the peso and emerging markets.

The Risk On index is a proprietary indicator, designed and maintained by Mauricio Mercenario. It is a market-reading tool, not investment advice.
