LSEG brings PriceStream’s upgraded FX infrastructure to Singapore

LSEG has extended its PriceStream foreign-exchange service to Singapore, adding a regional deployment of the AWS Outposts infrastructure used in its New York upgrade. The 14 October announcement advances a plan first outlined in July and gives Asia-Pacific pricing and execution a local infrastructure base.[1][2]

PriceStream distributes continuous executable quotes from identified liquidity providers. Clients request streaming prices from multiple providers and can trade through FXall, FX Trading or a FIX application programming interface. The infrastructure change therefore supports an established institutional trading workflow, including firms connecting their own systems directly to the service.[3]

The performance evidence belongs to the earlier deployment

On 23 July, LSEG described the first installation at Equinix’s NY6 data centre and reported an improvement of more than 70% in average application latency across migrated environments. It also identified Singapore and London as planned expansion locations. October’s announcement confirms the Singapore extension; it publishes no equivalent local benchmark. The reported measure was average application latency in the migrated environments; LSEG supplied no client-by-client end-to-end execution comparison.[2][1]

The architecture helps explain the approach. AWS Outposts puts AWS-managed computing and storage equipment at a customer site while retaining cloud-compatible interfaces and management. Applications can therefore use local processing capacity close to connected systems. The geographic location of the hardware remains relevant even when its operating tools come from a cloud provider.[4]

AWS’s network documentation distinguishes local connectivity from the service link back to an AWS Region. The latter supports management and traffic between the regional cloud and the Outpost. This separation allows a trading service to design its local execution path while maintaining the connections needed to operate the infrastructure; the precise routing depends on its deployment.[5]

LSEG identifies software delivery and monitoring as benefits of the platform. Participating banks and trading firms gain a regional price-distribution service whose responsiveness can be assessed on their own connection and order flow.[1]
