Question about Spread Volatility on Broker Platform (Forex)

Over the past few months, I've noticed that spreads on some major currency pairs, such as $EURUSD and $GBPUSD, have been highly volatile during Asian market hours, even when there's no significant news.

I'd like to ask friends and fellow traders in the forum if you've encountered a similar situation, and if anyone can provide information on whether this is normal or if it might be a sign to consider the liquidity of the broker I'm using.
