Saudi banks have recently begun applying enhanced compliance checks to transactions destined for the UAE, categorizing the country alongside jurisdictions like Iraq and South Sudan that are typically flagged for potential money laundering. While the Saudi Central Bank maintains that its regulatory framework is standard and lacks direct restrictions on any specific nation, three insiders confirmed that key institutions were instructed to increase scrutiny on Emirati settlements earlier this year.

The friction is hitting the private sector hard. Six business executives reported that payments are frequently returned or held in limbo without formal explanation, forcing some to route capital through third-party countries to maintain operations. One investor noted that even modest sums, previously processed within days, are now trapped for weeks. A Saudi source characterized these measures as a calculated, subtle signal to Emirati leadership amid years of diverging interests—ranging from oil production quotas to conflicting geopolitical stances in the Yemen conflict.

Despite these barriers, both nations remain deeply enmeshed. The UAE maintains that its Ministry of Economy has received no official complaints regarding these delays, emphasizing the longstanding commercial ties between the two. Analysts suggest that while the cooling of relations is evident, a total economic rupture remains unlikely, given that Saudi Arabia serves as the UAE's largest Arab trading partner. For now, the increased compliance hurdles serve as a quiet but effective lever in the competition between Riyadh and Abu Dhabi for regional financial dominance.
