When the bond market shows up to the party, it’s worth paying attention — it sets the tone… and the cost of capital.
Who hasn’t experienced the humiliation of being turned away at the door of a nightclub? It’s a rite of passage for many. But very few have managed to turn that frustration into a global hit.
That’s exactly what the band Chic did. On New Year’s Eve 1977, denied entry to the ultra-exclusive Studio 54, they went home, picked up a guitar and a bass… and channeled their anger into music. The result: “Le Freak,” a disco-funk anthem that likely earned them VIP status for life. “Le Freak” is a celebration of nonconformity — and a reminder that appearances aren’t everything.
In the world of finance, the “freak” is the bond market. Quiet, often operating in the shadow of its flashier cousins — equities and crypto — it tends to be overlooked. But when it takes center stage, it does so with impact. And in May, it made a comeback worth noting.
Overall, May was a good month for investors, bringing a welcome change of pace to equity markets. U.S. stocks led the way, with the S&P 500 gaining +6.2% — its best monthly performance since late 2023. Optimism spread globally: Europe rose +4.0%, China +5.3%, and Japan +5.3%. Closer to home, the Swiss SMI also posted a modest gain of +0.9%. Not every market can be a star every month.
Several factors supported this rebound. Corporate earnings and economic data were generally solid — though still reflecting the pre-Trump era, so they should be interpreted cautiously. Geopolitical and trade tensions, especially between the U.S. and China, took a breather. And markets seem to be decoding Trump’s style: lots of noise, little action. Wall Street has even coined a mocking acronym: TACO — Trump Always Chickens Out.
But the real signal didn’t come from the noise — it came from the bond market.
I like to remind people how crucial this market is. Often overlooked, the bond market is the backbone of global finance. It’s larger than the stock market, it enables governments and companies to fund themselves, it keeps the financial system running — and it sets the price of money itself: from U.S. Treasury yields to the mortgage rate of an average household.
In many ways, the bond market has more immediate power than voters. It acts as a real-time referendum on political credibility. Whatever a president says, the bond market votes every day — with interest rates. And right now, that vote is tinged with doubt.
When investors demand higher yields (or pay less for bonds), it’s a sign of mistrust. Because when you truly believe in someone, you’re usually willing to lend at a lower rate — especially if that someone is the world’s largest economy.
Higher rates create headaches, both for politicians and global markets. But let’s not overreact. A 10-year U.S. Treasury yield of 4.38% (as of writing) is high compared to the past 15 years. Yet in a world of stronger inflation and with a longer historical view, maybe this is closer to the norm than the exception. Personally, I find it more concerning that rates in Switzerland are still hovering near 0%.
Again, the real danger is a rupture in the bond market. We’re not there, but the warning signs are flashing.
I see three possible scenarios ahead:
- The U.S. administration adjusts course, tensions ease, and/or the Fed adopts a more dovish stance — bondholders benefit.
- Rates keep rising, and tougher times follow.
- Markets keep swinging between these two — as they’ve been doing for months.
Right now, I lean toward the third scenario. But one thing is certain: I won’t be leaving the freak outside my asset allocation club.
To sum up, May was a good month for markets — and that’s something to appreciate. Global tensions cooled, uncertainty became more manageable, and short-term outlooks improved. But staying grounded means listening to all the signals — not just the ones in the spotlight. Because in finance, the quietest voices often carry the most weight.
