So we're in April again, and honestly, the pattern is starting to feel familiar. Last year at this time, the dollar index was having what I'd call its "dark month" - dropped from 104 to 98 in just a few weeks. Everyone was talking about de-dollarization then. Now here we are a year later, and the exact same script seems to be playing out.

Let me break down what happened last April that spooked the markets. First, the tariff situation completely reversed course. Remember when Trump was showing off those tariff rate charts? Currencies from high-tariff countries got absolutely hammered, panic was everywhere. But then it became clear tariffs were just negotiation theater. Capital that had been flowing into the US during the Biden years started reversing hard - euros, emerging market currencies, everything started flowing back out.

Second, the Fed's independence took a hit. Trump was publicly calling out Powell for moving too slowly on rate cuts, even threatening to replace him. That alone shifted expectations dramatically - one-year SOFR swap rates dropped almost 20 basis points in a single month. When people stop trusting central bank independence, they stop holding the dollar.

Third, there was this massive shift in how central banks thought about reserves. Gold broke $3,000 for the first time, and central banks went all-in on diversifying away from dollars. That's when you know de-dollarization is becoming structural, not just cyclical.

Now fast forward to this April. Oil's still above $95, but honestly, nobody cares much whether the US and Iran actually reach a deal. The euro and Aussie dollar are back to pre-war levels. The yuan just hit a new yearly high. Every time there's negative news, the dollar's bounce-back is getting weaker and weaker.

The equity markets are showing the same pattern too - US stocks recovered all their losses, ChiNext climbed above 3,500. It's like we're watching the same capital reallocation happen again. The thing is, high oil prices and risk-off sentiment that usually support the dollar? They're not sticking around. If this geopolitical situation resolves poorly, the de-dollarization trend will probably keep going.

That said, there's one thing worth noting. Earlier in the year when economic data was actually improving, the whole de-dollarization momentum basically stalled. So we're not looking at a one-way move down for the dollar - it'll depend on what the data shows.

Bottom line: Last year's April playbook is repeating. After the market digested the war shock, de-dollarization is back on the menu. But it won't be smooth sailing - everyone's already positioned for it this time, so the early movers are going to face real competition.
