Financial leaders are working around the clock to shore up deposits, stave off additional bank runs, and arrange quick deals so that sturdier firms can absorb at-risk competitors. Their efforts to reinforce the global system will be closely scrutinized.

But one of the key takeaways from SVB’s unwinding is that how weak banks communicate in the coming days and weeks may become just as crucial to maintaining stability. Sure, SVB was going to take a financial hit under any circumstance, but profound missteps in its messaging strategy seem to have made a bad situation worse, possibly fueling the massive bank run that saw its clients attempt to pull $42 billion in a single day.

Here’s what business leaders tell Fortune about communicating during a fast-moving, high-stakes situation.

Focus on your stakeholders from the beginning

In its letter to customers and investors on March 8, SVB opened with this line: “Today we took strategic actions to strengthen our financial position—repositioning SVB’s balance sheet to increase asset sensitivity to take advantage of the potential for higher short-term rates, partially lock in funding costs, better protect net interest income (NII) and net interest margin (NIM), and enhance profitability.”

The line may be detailed, but it doesn’t directly address shareholders’ and customers’ chief concern: What are you doing for me?

Andy Gilman, CEO of CommCore, would have opened with a different missive. “I would start with something that says we are taking some actions to strengthen our financial position and also to make sure that you—as investors and customers—are protected.” By contrast, SVB’s letter references ongoing support for “clients, employees, and investors” in the last line.

Similarly, Will Chabot, a managing director at communication firm Stu Loeser & Co., says corporate talking points about actions taken should be both clear and dominant, which isn’t his impression of SVB’s message. The message circulated after the former CEO’s now infamous Zoom call with venture capitalists on March 9 was to “stay calm,” he says. “[But] you don’t want some throwaway line, or a line that doesn’t address the situation completely, to be the one circulating on Twitter.”

Don’t lean on your past

Kelcey Kintner, a senior vice president at the international crisis PR firm Red Banyan, argues that the bank spilled too much ink painting “a rosy picture touting its credentials and experience” in its stakeholder letter.

One section reminds readers that “SVB is a trusted financial partner of the global innovation economy,” and several others are dedicated to the bank’s history. To be sure, the bank’s track record as a partner to entrepreneurs is meaningful, but that kind of goodwill and trust from clients can quickly evaporate in a crisis, according to experts.

“As opposed to reassuring us with facts, SVB took the ‘you owe us your loyalty’ route—and in a panic situation, that messaging doesn’t work,” an unnamed venture capitalist told Axios. “While VC firms do deals together frequently, we also compete. And the idea that we all trust each other enough in a prisoner’s dilemma is wrong.”

Chabot urges business leaders to focus on the present moment, be clear, and explain what the company is doing when in a tough spot. “The best message isn’t going to be a flowery inspirational rallying cry meant to rejuvenate tired supporters and win over your detractors,” he explains. “Crisis communication should not look like a campaign speech.”

Be clear and overshare

The best, most reassuring communication is honest and transparent—a rule that’s somewhat obvious in theory but easily overlooked during a crisis. Kintner says to look no further than the recent meltdown at Southwest Airlines, when the company blamed the weather for nearly a week of cancellations in December, even though other airlines only suffered single-day delays. “SVB had an opportunity to be more forthcoming and transparent with shareholders, which might have helped ease panic somewhat,” she says.

Instead, SVB’s first announcement about the crisis, a press release published on March 8, was woefully “convoluted,” TechCrunch wrote. Its timing was also questionable: SVB’s news appeared just after the California-based crypto bank Silvergate collapsed.

Generally speaking, companies too often fear oversharing in crises, Chabot says: “They think the more they share, the more attention that will bring to themselves, or the worse their problem looks.” But when companies say that “everything is cool,” whereas the prevailing narrative is that something has gone terribly wrong, the mismatch forces people to make ill-informed opinions, he says. For SVB, that created additional turmoil, especially since its audience—entrepreneurs, venture capitalists, and tech investors—is chronically online. “When people are not getting the full picture, they can tell, and they’re really going to turn up the volume,” Chabot says.

Don’t call attention to the wrong things

Companies should feel compelled to give customers and investors context about their own situation, but Gilman suspects that SVB made a mistake in highlighting factors outside its control.

He zeroes in on a paragraph in the letter to clients: “While VC deployment has tracked our expectations, client cash burn has remained elevated and increased further in February, resulting in lower deposits than forecasted. The related shift in our funding mix to more, higher-cost deposits and short-term borrowings, coupled with higher interest rates, continues to pressure [net interest income] and [net interest margin].”

“That kind of screams, ‘We’re in trouble,’” Gilman says. “Given what people were saying about them, that note probably added fuel to the fire and caused more people to say, ‘We’re not comfortable with our money in here.’”

Be fast, not flowery

While companies have to reflect on how a message will come across, time is of the essence in a crisis, says Red Banyan’s Kintner: “A company must capitalize on its window of opportunity when the audience is going to be the most receptive.” 

Don’t waste time trying to be a poet, says Chabot. “Crisis communication is not about a clever turn of phrase. It’s about relaying context and specific, clear information as quickly as possible.”

In an age when news spreads quickly on social media platforms, speedy circulation of corporate statements takes on heightened importance. It’s tough to regain authority when online chatter takes control of the story.

It would behoove companies facing a crisis to remember that information travels well beyond their intended audience, says Chabot. A letter to one group will be posted online and decoded by scores of others, including people who have no connection with or interest in the firm. Your single message should be unambiguous because reporters, Redditors, customers, and investors can respond very differently to the same message, Chabot says.

Your audience is not who you think it is

“Asking folks on a quote-unquote private investor call to remain calm means one thing to the person you’ve worked with for 20 years, whose trust you’ve earned,” says Chabot. But a random person on Twitter or Reddit may read “remain calm” as an admission that the company has lost control.

To spot potential pitfalls, companies should include multiple players in the room when crafting a message, says Gilman. Crisis communication is a team sport.

He notes that companies often work with their legal or finance teams to craft a public message but forget that “there are two courts to think about.” Lawyers may not consider the impact of certain types of language in the court of public opinion, and that needs to be balanced with the very real threat of lawsuits.
