‘72-Hour Rule’: Debt Investors Take Fright at Trump’s Social Media Deluge

In This Article:

(Bloomberg) -- Waiting three days to see whether he U-turns before making trades. Rushing bond sales through before he wakes up and starts posting. Shifting lending to tariff-proof tinned-food producers or cellphone providers.

These are all ways that battle-scarred credit investors and bond arrangers are desperately trying to navigate the constant barrage of policy bombshells from President Donald Trump’s social-media account.

More than a dozen lenders and debt bankers spoken to by Bloomberg, most of whom asked to stay anonymous discussing commercially sensitive information, said they’d been forced into a series of defensive moves after many were burned by initial efforts to treat Trump’s pronouncements with full seriousness.

When he posted about a 200% tariff on European wine, for example, a host of investment banks started doing over-the counter trades on potentially affected companies at below market price to get ahead of the crowd, according to a person with knowledge of the situation. This included the bonds of packaging specialists Ardagh Group SA and Verallia, and Italian label maker Fedrigoni SpA.

But in a few days, the downward lurch in these bond prices was completely erased after it became clear the threat wasn’t real. When tariffs were announced there was no mention of wine.

It wasn’t an isolated case in credit markets as Trump negotiates via social media and “floods the zone” with often contradictory messages. A threat to impose 50% tariffs on Canadian steel was also swiftly abandoned.

Some banks and investors have started adopting a “72-hour rule” after all Trump missives, according to three senior debt financiers, believing that a policy might actually come into place if he still hasn’t changed tack by then.

Markets whipsawed last month after Trump said he’d impose once-in-a-century tariffs on allies and enemies alike. A savage selloff, particularly in US stocks and Treasuries, pushed him to pause for 90 days on all countries other than China, triggering a relief rally that helped wipe out some, but not all, losses.

“We don’t act immediately anymore because there’s always the risk of a reversal. I think we’re becoming immune to some of it,” said Catherine Braganza, a portfolio manager at Insight Investment, who pointed out that Europe’s junk-bond market has recovered almost entirely after suffering one of the worst routs in years in early April.
