LONDON (Reuters) - As calm returns to markets roiled by banking havoc in March, it's time to reflect on the policy response.

The International Monetary Fund has warned of a "perilous combination of vulnerabilities" in markets. The Bank of International Settlements says for the first time since World War Two that central banks are dealing with surging inflation coinciding with very high debt levels, threatening economic stability.

"The risks to the financial system are not as pressing as they were in March but that doesn't mean the crisis has passed," said Northern Trust chief economist Carl Tannenbaum, who worked in the Fed's risk section during the 2008 global financial crisis.

Here, experts weigh in on what policymakers did well in March with takeaways for the future.

1/ STICK WITH THE PLAN

The Federal Reserve and the European Central Bank continued hiking rates in March as Silicon Valley Bank (SVB) failed and Credit Suisse (CS) was forced to merge with UBS.

Rapid rate rises after years of ultra-low rates have caused pain. But changing course as markets slid could have exacerbated that.

"If they hadn't have done those rate increases, there was a danger that people would look at that and say, oh, my god, the situation is even worse than we thought it was," said Dario Perkins, managing director, global macro at TS Lombard and a former advisor to Britain's Treasury.

A measure of volatility in the Treasury market has eased after hitting its highest level since 2008 in March.

Low and stable inflation is good for markets and the economy, so central banks had to show their seriousness on inflation, Tannenbaum added.

2/ LOUD AND CLEAR

After staying the course comes selling the message.

The Fed met just 12 days after the SVB failure and the ECB's March 16 meeting was two days before Credit Suisse's rescue. U.S. regional bank stocks tanked 36% in March.

Central banks softened rate rises with communication that was mindful of instability risks, showing reassuring "humility", said Perkins.

Not all communication has been stellar.

The Swiss National Bank said on March 15 Credit Suisse met capital and liquidity requirements.
