The French Bond Trade That Blew Up: Le Spread Hit 1.55 Points, and the Smartest Money Was the Desk That Said No

L&G’s fund managers saw a spread they hadn’t seen in years and wanted to buy. Their own rates strategists said no — and two days later looked like geniuses. A yield that’s historically high is high for a reason, and the reason can get worse before it gets better.

The spread over bunds hit 1.55 points Friday; the 2011 record is 1.81 — and the desk that stayed out was the one that got it right.
In one line: Borrowed-money bets on French bonds unwound all at once last week, and the fund that refused to buy the dip is the week’s best argument for keeping duration short.

The best trade of the week in Paris was the one nobody put on. At L&G Asset Management in London, fund managers looked at French government bonds after the first leg of the selloff and saw a gift: a spread over German bunds they hadn’t seen in years, plus the quiet tailwind of roll-down (as a five-year bond ages into a four-year, its spread usually tightens). The firm’s rates strategists vetoed it. Too many investors were still long France, they argued, and a crowd heading for one door at the same time makes its own stampede. Thursday’s disorderly selloff settled the argument. John Roe, L&G’s head of multi-asset allocation, told the Journal’s Joe Wallace it’s “very tempting when you see numbers you’ve not seen for a long time” to dive in.

The trades that blew up were carry trades — Wall Street for borrowing in one market to buy in another. The popular version: own French and Italian bonds, short German bunds, and collect the yield gap while waiting for it to narrow. A second version bought French and Italian paper and sold interest-rate swaps against it, stripping out the rate bet and leaving a pure wager that a country France’s size wouldn’t default inside two to five years. Both assumed the gap was already wide and bound to come back in. Instead it widened — a shift in presidential polling, a poorly received budget and a global government-bond selloff all piled up at once — and SMBC’s Hank Calenti says the intra-Europe carry trade “has gotten crushed.”

Why so violent? Ownership. France’s €3.5 trillion bond market — about $3.9 trillion — is the largest in Europe after years of deficits, and more than half of it, by MUFG’s count, sits with foreigners, who have less reason to hunt for yield in Paris now that they can earn it at home or in Germany. Short-term French yields swung as much as 0.40 percentage point over two days; Calenti’s read is that a slow bleed turned into a rout once risk managers started tapping shoulders. The spread over bunds hit 1.55 points Friday; the record, from November 2011, is 1.81. RBC BlueBay’s Mike Bell thinks ratings firms could downgrade France.

The number you haven’t seen in years

Here’s where this stops being about France. Pimco’s Konstantin Veit says hedge funds are unwinding carry trades broadly, and France is just one leg of them. The behavioral trap is universal, too: a yield that looks historically high is high for a reason, and the reason can deteriorate before the European Central Bank — which some investors count on as the eurozone’s ultimate backstop — decides it has to act. By Tuesday’s close the French 10-year was 4.755%, versus 3.497% for Germany and 4.530% for Italy.

Our read

This is Fixed Income (IN02) with a Behavioral chaser. The French lesson is the one the desk has been living for a month: long duration is where a rate shock does its damage, and ‘cheap’ isn’t a price, it’s a direction. Our stance hasn’t changed — safe money in Treasury bills and floating-rate paper (SGOV, held in 49 books, and USFR, held in 14), long Treasurys avoided. TLT sits in just 4 books, and Tuesday’s table says why: 77.28, down 11.3% for the year, while SGOV was up 0.1%. Nothing added anywhere.

The L&G story is also a governance story. The fund managers weren’t wrong about the math; they were about to be early, which in a crowded trade is the same thing as wrong. Someone with no position had the standing to say no — and that’s what a written investment policy does for a household. If a yield this fall has you wanting to lock it in, check whether the lock is on the yield or on you. Fifteen minutes with the fixed-income sleeve now beats learning what duration means in a downpour.

What It Means For Your Portfolio

Avoid — long duration; don’t buy a yield because it’s new

No action — long duration (TLT) stays avoided and safe money stays in bills and floating-rate Treasurys (SGOV, USFR); a yield you haven’t seen in years is a reason to ask why, not a buy order.

General planning principles, not advice for anyone in particular. When a yield jumps to a multiyear high, ask who’s selling and whether they’re done — a crowded position unwinding is the one time ‘buy the dip’ most reliably fails. Keep the part of your money that can’t take a loss in short Treasurys and floating-rate paper, where a rate shock is a non-event.

Write the rule before the temptation shows up: what you’ll buy, at what maturity, and who has to agree. The point of the rule is to have someone who can say no when the numbers look like a gift.
